## What's Live Now

| Feature                       | Status      |
| ----------------------------- | ----------- |
| Bridge (60+ chains → MegaETH) | ✅ Live      |
| Swap (any token → USDm)       | ✅ Live      |
| Prediction Markets            | 🔒 Waitlist |

## Step 1 — Create an Account

No wallet extension required. evently uses **Privy** for frictionless Web2 onboarding — your on-chain wallet is created automatically in the background.

**Sign in with:**

* **Email** — enter your email, click the magic link, done
* **Google, Twitter, Discord, GitHub, or Apple** — one-click social login

Privy automatically creates an **embedded wallet** on first login. No seed phrase, no browser extension, no ETH needed to start.

**Already have a wallet?** MetaMask, Rabby, Coinbase Wallet, and Rainbow are also supported as external wallet options.

***

**Gas fees are sponsored.** Core trading operations (buy, sell, create market, resolve, claim) are gasless — the protocol covers gas on your behalf. You never need to hold ETH to trade.

***

## Step 2 — Get USDm

All trades use **USDm** — the USD-pegged stablecoin on MegaETH.

**Bridge:** [evently.market/bridge](https://evently.market/bridge) — LiFi, 60+ EVM chains.

# Prediction Markets

## Overview

evently Markets is the platform's core product — a **LMSR-based prediction market** where anyone can create or trade on outcomes using USDm (the MegaETH stablecoin).

You don't bet. You **trade your conviction**. Information becomes a financial asset — priced by the market, settled on-chain, with instant finality on MegaETH's \~10ms blocks.

Markets cover Crypto, Politics, Fun, Technology, Business, Science, World, Entertainment, Pop Culture, and more. Many markets are sourced from Polymarket and display live Polymarket odds alongside evently's own prices for comparison.

Each outcome is represented as a tradable **ERC-1155 share**. One winning share redeems for exactly **1 USDm** after market resolution — regardless of total volume or how many people traded the same way.

***

## Access

Markets are structured around two independent whitelists:

* **Traders** — during beta, access requires an invite code or waitlist approval. At public launch, trading is open to all.
* **Market creators** — always require explicit creator whitelist approval. This applies even at public launch. Contact the evently team to apply.

To gain trader access during beta:

* **Invite code** — redeem a code from an existing member
* **Waitlist** — submit your wallet at [evently.market/markets](https://evently.market/markets)

***

## Fee Structure

| Fee           | Recipient                   | Basis Points               |
| ------------- | --------------------------- | -------------------------- |
| Creator fee   | Market creator              | 100 bps (1%)               |
| Treasury fee  | evently protocol treasury   | 100 bps (1%)               |
| Resolver pool | Resolver / staking post-TGE | 50 bps (0.5%)              |
| **Total**     |                             | **250 bps (2.5%) — fixed** |

Admin markets (created by evently team): creator cut goes to treasury instead.

***

## Pricing Mechanism — LMSR

Prices are determined by the **Logarithmic Market Scoring Rule (LMSR)**, the same mechanism used by Polymarket. The LMSR guarantees that:

* Being correct always yields a profit (unlike parimutuel)
* Prices always sum to exactly 100%
* The market maker (AMM) is always solvent

**Cost function:** `C(q) = b × ln( Σ exp(q[i] / b) )`

**Implied probability of option i:** `P(i) = exp(q[i]/b) / Σ exp(q[j]/b)`

`b = 200 USDm` controls price sensitivity. At creation all options start at equal probability (e.g. 50/50 for binary markets).

***

## Order Matching — CLOB + AMM

Trades are routed through two layers:

1. **CLOB (Central Limit Order Book):** resting limit orders are matched first at price-time priority
2. **LMSR AMM:** any remaining budget is priced by the AMM as market maker of last resort

**Buying:** CLOB ask orders at or below your price are filled first. Remainder goes to the AMM.

**Selling:** instant sell to the AMM via `sellToAMM()` with mandatory slippage protection (`minUsdmOut`), or post a limit ask via `placeOrder(SELL, ...)`.

Each address can hold up to **10 active resting orders per market** (across all options and sides). The overall book cap remains 200 orders per (market, option, side).

***

## Market Lifecycle

```
Active → BettingClosed → Resolved → [Disputed] → Finalized
                                          |
                                    Cancelled / Slashed
```

### 1. Active

Shares can be bought and sold. Market is open until `bettingDeadline`.

### 2. BettingClosed

Deadline passed. No more trades. Waiting for resolution.

### 3. Resolved

Creator declares the winning option with a mandatory **evidence hash** (on-chain audit trail). A **24-hour dispute window** opens.

### 4. Disputed

Any address that has traded on the market can dispute the resolution by posting **50 USDm collateral**. The `disputeResolver` (a dedicated role, separate from admin) adjudicates with a mandatory evidence hash. The dispute window is 24 hours after resolution.

**Admin disputes are free** — admin can dispute any market without posting collateral (security function, not a profit mechanism). Imported Polymarket markets can be disputed under the same rules.

### 5. Finalized

No dispute raised (or dispute settled). Winners can redeem shares at **1 USDm each**.

### 6. Cancelled

Markets with no trading activity can be cancelled by the creator, admin, or anyone after `resolutionDeadline`. **Markets with any trading activity cannot be cancelled** unless `resolutionDeadline` has passed — they must be resolved. On timeout cancellation, any accrued creator fees are confiscated to the treasury.

### 7. Slashed

Admin can slash a market in `Active`, `BettingClosed`, `Resolved`, or `Disputed` status. Cannot slash `Finalized`, `Cancelled`, or already-`Slashed` markets. Creator collateral goes to treasury; shareholders receive a pro-rata refund from the pool + subsidy.

***

## Market Creation

### Creator Whitelist

Market creation requires explicit approval on the creator whitelist — separate from the trader whitelist and always enforced. Apply via the evently team.

### Community Markets (Creator-Whitelisted Users)

* Requires **50 USDm collateral** + LMSR subsidy (`b × ln(n)` USDm)
* Collateral returned on honest resolution
* Creator earns **1% of all volume**, claimable after finalization
* Must set clear `resolutionCriteria`
* 2 to 4 options; question max 300 characters; options max 100 characters each
* Betting window must be at least 1 hour (prevents flash markets)

### Official Markets (Admin)

Created by the evently team — no collateral required. Displayed with an **Official** badge. Many are sourced from Polymarket with live odds via the CLOB API.

### Imported Polymarket Markets

Any creator-whitelisted user can mirror a Polymarket market by paying a **10 USDm one-time import fee** (to treasury). The Polymarket `conditionId` must be a valid 66-character lowercase hex string starting with `0x` — duplicates are blocked on-chain.

### Oracle Markets

Creator-whitelisted users can create binary price-feed markets that resolve automatically. Requires exactly 2 options and a valid Redstone price feed ID (ETH, BTC, SOL, MEGA). Collateral and fees are the same as standard markets. See the [Oracle Markets](#oracle-markets) section below.

***

## Trading

```
placeOrder(marketId, optionIndex, side, quantity, pricePerShare, minFill)
```

* `side`: BUY or SELL
* `pricePerShare`: limit price in USDm (18 decimals), must be between 0 and 1
* `minFill`: slippage guard — reverts if total shares filled < this value
* BUY orders escrow USDm upfront; SELL orders escrow shares upfront

For instant AMM sells:

```
sellToAMM(marketId, optionIndex, shares, minUsdmOut)
```

`minUsdmOut` is required and prevents sandwich attacks against the AMM.

***

## Dispute Rewards — Monthly VRF Lottery

When a dispute is settled **in the disputer's favour** (creator was wrong):

* Creator loses their 50 USDm collateral. **25 USDm** goes to the disputer as a reward (regular disputer also receives back their own 50 USDm collateral, totalling 75 USDm). If admin disputed, the full 50 USDm goes to treasury.
* All creator accrued fees are slashed to treasury.
* **30% of the total net treasury gain** (slashed collateral portion + slashed fees) is allocated to the current month's lottery pool.

At the end of each 30-day cycle, `distributeMonthlyDisputeRewards()` draws a **single winner** using **Drand BLS12-381 VRF** (MegaETH native precompile). The entire pool goes to that winner — winner-takes-all. The winner index is derived from `keccak256(vrfProof) % count`, verified on-chain.

This incentivises honest dispute participation without creating runaway dispute abuse, and adds provably fair randomness to the outcome.

***

## Oracle Markets

Oracle markets are binary markets where the outcome is resolved **automatically** from a live price feed — no human resolver needed.

Instead of a creator calling `resolveMarket()`, a keeper reads the on-chain Redstone price and calls `resolveMarketWithOracle()`. The contract verifies the price signature on-chain (≥3 signers from `redstone-primary-prod`) and resolves instantly.

### How it works

| Field             | What it means                                               |
| ----------------- | ----------------------------------------------------------- |
| **Price feed**    | The asset being tracked (ETH, BTC, SOL, MEGA)               |
| **Strike price**  | The price threshold in USD (8 decimal places)               |
| **Above / Below** | Whether option 0 wins if price is above or below the strike |

**Example:** *"Will ETH be above $3,000 at 31 May 00:00 UTC?"*

* Strike = `300000000000` (3000 × 10⁸)
* Strike Above = `true`
* If the Redstone ETH/USD price ≥ $3,000 → option 0 ("Yes") wins
* If below → option 1 ("No") wins

### Creating an oracle market

Oracle markets require exactly **2 options** and a whitelisted creator, just like regular markets. The additional fields (price feed, strike, direction) are set at creation and cannot be changed. Collateral and fees work identically to standard markets.

### Resolution

Any address can trigger resolution once the betting deadline has passed and before the resolution deadline expires. Resolution is permissionless — no keeper trust required, since the price data is cryptographically signed by Redstone validators on-chain.

***

## Lucky Trader Weekly Raffle

Every week, evently picks one active trader at random to win a **USDm bonus** from the protocol treasury.

### How to enter

Just trade. Any call to `placeOrder` or `sellToAMM` during the current week automatically enters your address into that week's raffle. You are entered **at most once per week** — submitting multiple trades doesn't give more entries.

The raffle tracks up to **500 unique addresses** per week.

### Winner selection

At the end of the week, the admin draws the winner using **Drand BLS12-381 VRF** (MegaETH's native randomness precompile). The winner address is derived from `keccak256(vrfProof) % traderCount` — fully verifiable on-chain. The result is final and cannot be replayed.

The winner receives the full bonus in USDm, paid directly from the treasury. The `LuckyTraderWinner` event is emitted and displayed live in the **Lucky Trader Banner** on the frontend.

### Frontend banner

The `LuckyTraderBanner` component on the markets page shows:

* The current week's eligible trader count
* The latest winner (address + bonus amount), flashing green when a new winner is drawn

***

## Redeeming Winnings

After finalization:

```
redeemWinnings(marketId)
```

Each winning share redeems for **exactly 1 USDm**. Solvency is guaranteed by the LMSR invariant: `poolBalance + subsidyDeposited >= total winning shares`.

***

## Polymarket Integration

Official markets import odds and volume data from [Polymarket](https://polymarket.com) via the Gamma API and CLOB price history API. Polymarket odds are displayed for reference — evently prices are set independently by the LMSR AMM.

# Swap & Bridge

## Overview

evently integrates [LiFi](https://li.fi) for cross-chain swaps and bridges, accessible directly from the app at no extra cost beyond protocol fees.

* **Swap page** — swap any token to USDm (or any other token) on MegaETH mainnet
* **Bridge page** — bridge assets from Ethereum or other chains to MegaETH

Both features are available without leaving the evently interface.

***

## Getting USDm

USDm is the base trading token for all evently prediction markets. To get USDm:

1. Go to [evently.market/swap](https://evently.market/swap)
2. Select your input token (ETH, USDC, USDT, etc.)
3. Select USDm as output
4. Confirm — your USDm is ready to trade instantly

***

## Bridging to MegaETH

To move assets from Ethereum or other L2s to MegaETH:

1. Go to [evently.market/bridge](https://evently.market/bridge)
2. Select your source chain and token
3. Select MegaETH as destination
4. Confirm — bridging typically takes seconds

LiFi supports **60+ routes** across major chains and bridges.

***

## Swap Points

Every swap recorded through evently earns **Swap Points**, stored permanently onchain in `EventlyProfiles.sol`.

* **Rate:** 5 points per $0.01 USD volume
* **Cooldown:** 30 seconds between recorded swaps
* Volume is tracked in USD cents

This creates a loyalty incentive for routing swaps through evently rather than external DEX aggregators.

***

## Technical Integration

The swap and bridge widgets are powered by the LiFi SDK (`@lifi/widget`). The frontend component is `LiFiSwap.tsx`.

MegaETH is configured as a supported chain in the LiFi widget:

```ts
// Chain ID 4326 — MegaETH Mainnet
chains: { allow: [4326] }  // Destination
```

***

## Supported Chains (Bridge)

| Chain            | Support    |

USDm (MegaETH Stablecoin)
Address: 0xFAfDdbb3FC7688494971a79cc65DCa3EF82079E7
Chain: MegaETH Mainnet (Chain ID 4326)
```


# Architecture Overview

## Contract System

evently is composed of independent smart contracts deployed on MegaETH mainnet.

```
+---------------------------+
|   EventlyProfiles.sol     |  ← Identity, stats, referrals, swap points
+------------+--------------+
             | reads/writes profile data
+------------v--------------+
|   EventlyMarkets.sol      |  ← Prediction markets (LMSR b=200 + CLOB)
|   Pending deployment      |    Pre-launch audit complete — 29 tools
+---------------------------+
```

The Markets contract is fully independent — it only reads USDm balances and approvals from the ERC-20 contract. The Profiles contract tracks identity and onchain social layer.

## Design Principles

* **Pull payment pattern** — winners pull funds via `redeemWinnings()` / `claimCancelRefund()`; no push transfers that can fail
* **Checks-Effects-Interactions (CEI)** — state reset before all external calls
* **ReentrancyGuard** — custom `_locked` mutex on all state-mutating external functions
* **No upgradeability** — contracts are immutable; new versions are redeployed
* **Transparency** — all events emitted for full on-chain auditability

***

## EventlyMarkets — Key Architecture

LMSR AMM (b=200 USDm) as market maker of last resort. CLOB (Central Limit Order Book) with bids and asks matched first at price-time priority.

```
BUY order  → CLOB asks filled first → remainder to LMSR AMM
SELL order → CLOB bids filled first → remainder rests as limit ask
           → OR: sellToAMM() for instant AMM execution
```

ERC-1155 shares: 1 winning share = 1 USDm at redemption. Solvency guaranteed by LMSR invariant: `poolBalance + subsidyDeposited >= total winning shares`.

Pre-launch audit complete (29 tools — 7 AI engines + 22 automated scanners). No blocking findings. Awaiting professional audit (two independent firms).

***

## Gas Configuration (MegaETH-Specific)

MegaETH has near-zero gas costs (\~10ms blocks, \~100K TPS). Transaction configuration in the frontend:

```ts
maxFeePerGas: 1_000_000n     // 1 gwei
maxPriorityFeePerGas: 0n
```

## Overview

EventlyMarkets is the production prediction markets contract for evently. It combines:

* **ERC-1155 tradable positions** — each trade mints/burns fungible shares per outcome
* **LMSR AMM** — Logarithmic Market Scoring Rule (b=200 USDm), permanent liquidity provider
* **CLOB (Central Limit Order Book)** — bids and asks with price-time priority, matched automatically on `placeOrder`
* **Creator economy** — 1% creator fee on all volume, claimable after finalization
* **Dual whitelist** — separate whitelists for market creators (always enforced) and traders (beta-only)
* **Dispute system** — any market participant can dispute; dedicated `disputeResolver` role settles; monthly VRF lottery for successful disputers
* **Oracle markets** — price-feed-based binary markets resolved automatically via Redstone Pull-model oracle

## LMSR Pricing Mechanism

LMSR (Logarithmic Market Scoring Rule) is an automated market maker where price follows a mathematically sound cost function:

```
C(q) = b × ln( Σ exp(q[i] / b) )
```

* `q[i]` = shares outstanding for option i
* `b` = liquidity parameter (200 USDm) — controls price sensitivity
* Cost to buy shares of option i = C(q after) - C(q before)

**Implied probability of option i:**

```
P(i) = exp(q[i]/b) / Σ exp(q[j]/b)
```

At initialization all quantities are 0, so each option starts at 1/n probability. Prices always sum to exactly 1.

**Market subsidy:** To bootstrap liquidity, the creator locks `b × ln(n)` USDm at market creation. This subsidy guarantees solvency: `poolBalance + subsidyDeposited >= total winning shares` at all times.

***

## Architecture

```
BUY order  -> CLOB ask orders filled first (price-time priority)
           -> Remaining budget routed to LMSR AMM

SELL order -> CLOB bid orders filled first (price-time priority)
           -> Unmatched remainder rests as limit ask in CLOB
           -> OR: sellToAMM() for instant execution at AMM price

Resolution -> Creator calls resolveMarket() with evidence hash (admin only for imported markets)
           -> 24h dispute window opens
           -> disputeResolver settles if disputed, with evidence hash

Finalized  -> Each winning share redeemable for exactly 1 USDm
Cancelled  -> All holders get pro-rata refund (poolBalance + subsidyDeposited)
```

***

## Market Lifecycle

```
Active → BettingClosed → Resolved → [Disputed] → Finalized
                                          |
                                    Cancelled / Slashed
```

1. **Created** — creator locks 50 USDm collateral + LMSR subsidy. `winningOption` initialized to `type(uint256).max` (sentinel: not yet resolved).
2. **Active** — users buy/sell shares via LMSR AMM and CLOB.
3. **BettingClosed** — after betting deadline, no new trades.
4. **Resolved** — creator declares winning option with a mandatory evidence hash. 24-hour dispute window opens.
5. **Disputed** — any market participant (trader or creator) can dispute by posting 50 USDm collateral. Admin disputes are free (security function). `disputeResolver` (not admin) adjudicates with evidence hash.
6. **Finalized** — dispute window closes without challenge, or `disputeResolver` settles. Winners redeem at 1 USDm/share.
7. **Cancelled** — only allowed before any trading activity, or after `resolutionDeadline` timeout. If timeout: creator's accrued fees are confiscated to treasury.
8. **Slashed** — admin can slash a market in `Active`, `BettingClosed`, `Resolved`, or `Disputed` status. Cannot slash `Finalized`, `Cancelled`, or already-`Slashed` markets. Creator collateral goes to treasury; shareholders get pro-rata refund.

**Mandatory resolution:** `cancelMarket` is blocked if `totalVolume > 0` or there are active resting orders, unless `resolutionDeadline` has passed. A market with any activity must be resolved (or time out) — it cannot be quietly cancelled.

***

## Access Control Roles

| Role               | Address                          | Capabilities                                                                                                               |
| ------------------ | -------------------------------- | -------------------------------------------------------------------------------------------------------------------------- |
| `admin`            | Multisig                         | Whitelist management, pause, ban, slash markets, admin markets, treasury (timelocked), admin cancel orders, transfer roles |
| `disputeResolver`  | Dedicated address                | `settleDispute()` only — cannot resolve markets or access treasury                                                         |
| Market creator     | `marketCreatorWhitelisted[addr]` | Create markets, resolve their own markets, cancel their own markets                                                        |
| Whitelisted trader | `whitelisted[addr]`              | Trade, dispute participated markets                                                                                        |

The `disputeResolver` and `admin` are separate roles. Admin cannot unilaterally settle disputes.

***

## Whitelist System

Two independent whitelists:

* **Trader whitelist** (`whitelisted`) — controls who can trade. Enforced during beta; disabled (`setWhitelistEnabled(false)`) at public launch.
* **Creator whitelist** (`marketCreatorWhitelisted`) — controls who can create markets. Always enforced.

Admin is implicitly a market creator. Admin also bypasses the trader whitelist — the `onlyWhitelisted` modifier always passes for admin, regardless of `whitelistEnabled`.

***

## Fee Structure

| Recipient      | Default                      | Description                                                       |
| -------------- | ---------------------------- | ----------------------------------------------------------------- |
| Market creator | 1% (`creatorFeeBps = 100`)   | Accrues in `creatorAccruedFees`, claimable after finalization     |
| Treasury       | 1% (`treasuryFeeBps = 100`)  | Accumulates in `treasuryBalance`                                  |
| Resolver pool  | 0.5% (`resolverFeeBps = 50`) | Redirected post-TGE to staking contract (24h timelock on changes) |
| **Total**      | **2.5% (fixed)**             | Not configurable                                                  |

Admin markets: creator cut goes to treasury.

**Dispute lottery allocation:** When a dispute is settled against the creator, 30% of the net treasury gain from that dispute (slashed collateral portion + slashed creator fees) is routed to the current month's dispute lottery pool instead of treasury. Distributed equally to all that month's successful disputers via `distributeMonthlyDisputeRewards()`.

***

## Dispute System

### Eligibility

Any address that has placed an order or sold to the AMM on the market (`hasParticipated[marketId][user] == true`) can dispute. Admin can always dispute (free of charge, security function).

Imported Polymarket markets can be disputed under the same rules.

### Collateral

* Regular disputer: posts 50 USDm. Returned + 25 USDm reward if right; forfeited to treasury if wrong.
* Admin disputer: no collateral posted. If right: nothing transferred. If wrong: 25 USDm reward added to treasury from creator collateral.

### Settlement

`disputeResolver` calls `settleDispute(marketId, creatorWasRight, finalOption, evidenceHash)`. Evidence hash is mandatory and emitted as `ResolutionEvidence` event.

**If creator was right (dispute rejected):**

* Disputer's 50 USDm collateral → treasury (if they paid it)

**If creator was wrong (dispute upheld):**

* Creator loses 50 USDm collateral:
  * Regular disputer: disputer receives back their 50 USDm + 25 USDm reward (75 USDm total). 25 USDm of creator collateral → treasury (after lottery deduction)
  * Admin disputer: full 50 USDm creator collateral → treasury (after lottery deduction)
* All creator accrued fees slashed to treasury (after lottery deduction)
* 30% of net treasury gain → current month's lottery pool (`monthlyDisputePool[month]`)
* Market finalized with `_finalOption`

***

## Monthly Dispute Lottery

Successful disputers accumulate entries in `_monthlyDisputers[month]` (one entry per won dispute). After month `M` ends, admin calls `distributeMonthlyDisputeRewards(M, vrfProof, vrfMessage)`:

* **Winner-takes-all** — one disputer is selected via Drand BLS12-381 VRF (MegaETH native precompile). `winnerIndex = uint256(keccak256(vrfProof)) % count`
* The full `monthlyDisputePool[M]` is transferred to the single winner
* VRF proof is verified on-chain before the winner is selected — invalid proof reverts
* Cannot be called again for the same month (idempotent guard)

**View:** `getMonthlyDisputers(month)` — returns disputer list for any past month.

***

## Oracle Markets

Oracle markets are binary prediction markets resolved automatically from a Redstone price feed, without requiring a human resolver.

### Creating an Oracle Market

```solidity
createOracleMarket(
    string  question,
    string[] options,         // exactly 2: e.g. ["Yes", "No"]
    Category category,
    string  resolutionCriteria,
    string  imageURI,
    uint256 bettingDeadline,
    uint256 resolutionDeadline,
    bytes32 priceFeedId,      // e.g. bytes32("ETH")
    uint256 strikePrice,      // in feed decimals (8 dp) — e.g. 3000_00000000 = $3,000
    bool    strikeAbove       // true: option 0 wins if price >= strike; false: wins if price <= strike
)
```

Constraints:

* Must have exactly **2 options** (binary market)
* `priceFeedId` must be non-zero (`bytes32("ETH")`, `bytes32("BTC")`, `bytes32("SOL")`, `bytes32("MEGA")`, etc.)
* `strikePrice` must be non-zero

### Supported Price Feeds

Feeds are sourced from the `redstone-primary-prod` data service (5-signer threshold). The `priceFeedId` is a right-padded `bytes32` encoding of the ticker string:

| Asset      | priceFeedId (bytes32 of ASCII) |
| ---------- | ------------------------------ |
| ETH / USD  | `bytes32("ETH")`               |
| BTC / USD  | `bytes32("BTC")`               |
| SOL / USD  | `bytes32("SOL")`               |
| MEGA / USD | `bytes32("MEGA")`              |

### Resolving an Oracle Market

```solidity
resolveMarketWithOracle(uint256 marketId, bytes32 evidenceHash)
```

* Permissionless — anyone can call it (typically a keeper script)
* Reads the Redstone price injected in calldata by the keeper
* `conditionMet = strikeAbove ? price >= strike : price <= strike`
* `winningOption = conditionMet ? 0 : 1`
* Requires: betting deadline passed, resolution deadline not expired, evidence hash provided
* Verifies Redstone data freshness and signature count (≥3 signers from `redstone-primary-prod`)

**View:** `getOracleConfig(marketId)` — returns `(priceFeedId, strikePrice, strikeAbove)`.

### Keeper Script

`scripts/resolve-oracle.js` scans all markets, identifies eligible oracle markets, wraps the call with `WrapperBuilder` (injects Redstone price calldata), and calls `resolveMarketWithOracle`. Configure with:

```
REDSTONE_DATA_SERVICE=redstone-primary-prod
DRY_RUN=true  # set to false to send actual transactions
```

***

## Lucky Trader Weekly Raffle

Every week, one active trader wins a USDm bonus drawn by VRF.

### Eligibility

Any address that calls `placeOrder` or `sellToAMM` is automatically entered into the current week's raffle — at most once per address per week (`hasEnteredWeek[week][addr]`). The raffle tracks up to 500 addresses per week (`MAX_WEEKLY_TRADERS`).

### Drawing the Winner

```solidity
drawLuckyTrader(
    uint256 week,
    bytes   vrfProof,
    bytes   vrfMessage,
    uint256 bonusAmount   // in USDm (18 decimals)
)
```

* Admin only; callable once per week (`weeklyLuckyDrawn[week]`)
* VRF verified on-chain via the Drand BLS12-381 precompile at `drandVerifier`
* `winnerIndex = uint256(keccak256(vrfProof)) % traderCount`
* `bonusAmount` is debited from `treasuryBalance` — reverts if treasury insufficient
* Emits `LuckyTraderWinner(week, winner, bonusAmount)`

**Views:**

* `getWeeklyTraders(week)` — returns all entered addresses for that week
* `getCurrentWeek()` — returns the active week number (`block.timestamp / WEEK_DURATION`)

### Admin Setup

`setDrandVerifier(address)` — set the Drand precompile address (admin only). The precompile address is network-specific; confirm via MegaETH documentation before deployment.

***

## Emergency Controls

### Pause

`pause()` — admin only. Blocks all trading and market creation. Auto-expires after 72 hours (`MAX_PAUSE_DURATION`). Anyone can call `unpause()` after 72h have elapsed; admin can unpause at any time.

### Ban

`banAddress(addr)` / `unbanAddress(addr)` — admin only. Banned addresses cannot interact with any market function.

### Admin Cancel Orders

`adminCancelOrders(orderIds[])` — admin only. Force-cancels resting orders and returns escrowed funds to order owners. Used to remediate griefing or banned-address orders.

### Timelocked Admin Operations

| Operation                    | Delay    | Request                                 | Execute                       | Cancel                       |
| ---------------------------- | -------- | --------------------------------------- | ----------------------------- | ---------------------------- |
| Treasury withdrawal          | 24 hours | `requestTreasuryWithdrawal(to, amount)` | `executeTreasuryWithdrawal()` | `cancelTreasuryWithdrawal()` |
| Resolver pool address change | 24 hours | `requestResolverPoolChange(addr)`       | `executeResolverPoolChange()` | `cancelResolverPoolChange()` |

## Token ID Encoding

```
tokenId = marketId * MAX_OPTIONS + optionIndex
```

`MAX_OPTIONS = 4`, so each market occupies token IDs `[marketId*4, marketId*4+3]`.

## CLOB Design

| Property           | Value                                                                                                     |

| Dead entry cleanup | Immediately on `cancelOrder` (`_cleanBook` — F-DS-M02); also before length check in `_restOrder` (INV-08) |
| Book cap           | 200 orders per (market, option, side) — griefing cap                                                      |
| Per-user cap       | 10 active orders per market per address — per-user saturation cap                                         |
| Min order value    | 1 USDm — prevents dust order griefing                                                                     |

## Profile Struct

```solidity
struct Profile {
    string username;
    uint256 swapVolumeUsd;    // Lifetime swap volume in USD cents
    uint256 swapPoints;       // Points earned from swaps
    uint256 tradePoints;      // Points earned from prediction market trades
    address referrer;         // Referrer address
    uint256 referralEarnings; // Total USDm earned via referrals
}
```

## Profile Creation

| Function                                                | Cost | Description                              |
| ------------------------------------------------------- | ---- | ---------------------------------------- |
| `createProfile(username, referrerUsername)`             | Free | Standard profile creation                |
| `createProfileWithPromo(username, referrer, promoCode)` | Free | Valid community code grants bonus points |

Profiles are **free for everyone**. Community codes grant a points bonus on creation.

Referrers are passed by **username** (not address). If the username doesn't resolve, it is silently ignored — no revert.

## Gas Sponsorship Flow

```
User triggers trade
  → sendGasless() checks shouldSponsor()
  → Privy packs UserOperation
  → Pimlico Paymaster signs (verifies whitelist + rate limit)
  → Pimlico Bundler submits to MegaETH
  → EventlyMarkets executes
  → Receipt returned synchronously via eth_sendRawTransactionSync
  → UI updates within ~10 ms
```

**Sponsored functions:** `placeOrder`, `sellToAMM`, `createMarket`, `resolveMarket`, `claimRewards`, `approve` (USDM)

***

## Session Key Flow

```
User clicks "Session" → one wallet popup
  → generatePrivateKey() — ephemeral key
  → smartWallet.signMessage(delegation)
    { sessionKey, selectors, contract, expiresAt, maxCalls }
  → stored in sessionStorage

Per trade (no popup):
  → tradeWithSession() — validates session
  → submits with session key context
  → up to 100 trades before session expires
```

***

## Security Controls

| Control                      | Value                            |
| ---------------------------- | -------------------------------- |
| Paymaster contract whitelist | EventlyMarkets + USDM only       |
| Sponsored selectors          | 6 core functions only            |
| Rate limit                   | 20 user ops / min / wallet       |
| Spend cap                    | 1 ETH equivalent / hour / wallet |
| Spam threshold               | 15 ops in 10 s → blocked         |
| RPC failover                 | 2 endpoints, health-checked      |

## Authentication & Wallets (Privy)

evently uses [Privy](https://privy.io) for authentication. Users sign in with email or social accounts — no wallet extension required.

**Supported login methods:** Email · Google · Twitter · Discord · GitHub · Apple · External wallets (MetaMask, Rabby, Coinbase Wallet, Rainbow)

On first login, Privy automatically creates an **embedded wallet** (EOA) in the background. This is then wrapped in an **ERC-4337 Kernel smart account** for gasless transactions.

```tsx
// frontend/app/providers.tsx
import { PrivyProvider } from "@privy-io/react-auth";
import { SmartWalletsProvider } from "@privy-io/react-auth/smart-wallets";

<PrivyProvider appId={PRIVY_APP_ID} config={privyConfig}>
  <SmartWalletsProvider config={smartWalletsConfig}>
    {/* wagmi + app */}
  </SmartWalletsProvider>
</PrivyProvider>
```

### MOSS Wallet (MegaETH embedded SDK)

Privy coexists with the **MOSS Wallet SDK** — MegaETH's native embedded wallet. The MOSS wagmi connector is registered in `providers.tsx` and is selectable via any standard wagmi `useConnect()` flow.

* Package: [`@megaeth-labs/wallet-wagmi-connector`](https://www.npmjs.com/package/@megaeth-labs/wallet-wagmi-connector)
* Connector id: `mossWallet` · rdns: `com.megaeth.account`
* Network is fixed per instance — evently pins MOSS to mainnet (chain `4326`)
* Quickstart: [docs.megaeth.com/moss-docs/wallet/quickstart](https://docs.megaeth.com/moss-docs/wallet/quickstart)
* Full reference: [docs.megaeth.com/moss-docs](https://docs.megaeth.com/moss-docs)

```tsx
// frontend/app/providers.tsx
import { megaWallet } from "@megaeth-labs/wallet-wagmi-connector";

const wagmiConfig = createConfig({
  chains: [megaethMainnet, megaethTestnet],
  connectors: [megaWallet({ network: "mainnet" })],
  transports: { /* … */ },
});
```

```tsx
// Anywhere in the app
import { useConnect } from "wagmi";

const { connect, connectors } = useConnect();
const moss = connectors.find((c) => c.id === "mossWallet");

<button onClick={() => moss && connect({ connector: moss })}>
  Connect MOSS Wallet
</button>
```

MOSS exposes additional MegaETH-native methods through the EIP-1193 provider (`wallet_balances`, `wallet_swap`, `wallet_grantPermissions`, …) — useful for paymaster setup, smart approvals, and the policy engine. See the [Methods Reference](https://docs.megaeth.com/moss-docs/methods/methods) and [Paymaster Guide](https://docs.megaeth.com/moss-docs/wallet/paymaster-setup) upstream.

***

## Gas Sponsorship

Core Evently operations are gasless. The protocol sponsors gas via a **Pimlico paymaster** (ERC-4337).

Sponsored functions: `placeOrder`, `sellToAMM`, `createMarket`, `resolveMarket`, `claimRewards`, `approve` (USDM).

```tsx
import { useSmartAccount } from "@/hooks/useSmartAccount";

const { sendGasless } = useSmartAccount();

// User never pays gas — routed through bundler + paymaster
await sendGasless({
  to: MARKETS_ADDRESS,
  abi: MARKETS_ABI,
  functionName: "placeOrder",
  args: [marketId, optionIdx, side, quantity, price, minFill],
});
```

See `frontend/lib/paymaster.ts` for the full whitelist and rate-limiting logic.

***

## Logo Component

The evently logo is rendered via the `EventlyLogo` component:

```tsx
import { EventlyLogo } from "@/components/EventlyLogo";

// Icon only — adapts to currentColor (dark/light)
<EventlyLogo size={32} />

// With dark background
<EventlyLogo size={32} withBg />
```

**Wordmark** — "event" in `#19191A` (dark), "ly" in `#70BAD2` (blue):

```tsx
<span>
  <span style={{ color: "var(--t1)" }}>event</span>
  <span style={{ color: "#70BAD2" }}>ly</span>
</span>
```

***

## Brand Colors

```tsx
// Tailwind custom colors (tailwind.config.js)
colors: {
  "mega-pink":  "#F786C6",  // Create market only
  "mega-blue":  "#70BAD2",  // Primary accent / logo "ly"
  "mega-green": "#6DD0A9",  // Buy / Yes / action
}

// CSS variables
"--pink":  "#F786C6"
"--blue":  "#70BAD2"
"--green": "#6DD0A9"
"--t1":    "#19191A"  // Primary text (light mode)
"--t2":    "#52525b"  // Secondary text
```

***

## MegaETH Chain Config (wagmi)

```ts
import { defineChain } from "viem";

export const megaEth = defineChain({
  id: 4326,
  name: "MegaETH Mainnet",
  nativeCurrency: { name: "Ether", symbol: "ETH", decimals: 18 },
  rpcUrls: {
    default: { http: ["https://mainnet.megaeth.com/rpc"] },
  },
  blockExplorers: {
    default: { name: "Blockscout", url: "https://megaeth.blockscout.com" },
  },
});
```

***

## Real-Time Events (MegaETH \~10ms blocks)

Use `watchContractEvent` for live trade feed — critical for MegaETH's \~10ms block finality:

```ts
import { useWatchContractEvent } from "wagmi";

useWatchContractEvent({
  address: MARKETS_ADDRESS,
  abi: MARKETS_ABI,
  eventName: "OrderFilled",
  onLogs(logs) {
    // Update live feed — fires every ~10ms block
    setTrades(prev => [...logs.map(parseTrade), ...prev].slice(0, 50));
  },
});
```

***

## Wiring Checklist

* [ ] `getImpliedPrices(marketId)` — display live YES/NO probabilities
* [ ] `quoteBuy(marketId, optionIdx, usdmIn)` — slippage preview before trade
* [ ] `quoteSell(marketId, optionIdx, shares)` — slippage preview for sells
* [ ] ERC-1155 position display in portfolio (`balanceOfBatch`)
* [ ] `watchContractEvent` polling for live trade feed
* [ ] Order book panel — display resting limit orders
* [ ] Post-trade confirmation toast with shares received
* [ ] `sellToAMM()` instant sell flow

***

## Contract Addresses

```ts
// config/markets.ts
export const MARKETS_ADDRESS = process.env.NEXT_PUBLIC_MARKETS_ADDRESS as `0x${string}`;
export const PROFILES_ADDRESS = "0x9F0708145BCCD1F5B16F610cB8a75A63fA4A9a24";
export const USDM_ADDRESS = "0xFAfDdbb3FC7688494971a79cc65DCa3EF82079E7";
```

***

## Gas Settings (MegaETH)

```ts
// Near-zero gas on MegaETH — use these for all transactions
const txConfig = {
  maxFeePerGas: 1_000_000n,      // 1 gwei
  maxPriorityFeePerGas: 0n,
};
```


# UX Upgrade — Gasless & Realtime

# Oracle & VRF Integration

Two MegaETH-native capabilities power automatic market resolution and provably fair randomness in evently: **Redstone Pull-model Oracle** and **Drand BLS12-381 VRF**.

***

## Redstone Pull-model Oracle

### How it works

Redstone uses the **Pull model**: price data is NOT stored on-chain. Instead, a keeper (off-chain script) fetches the latest signed price package from Redstone and injects it as calldata when calling `resolveMarketWithOracle()`.

The contract inherits from `RedstoneConsumerNumericBase` and reads the price inline using `getOracleNumericValueFromTxMsg(feedId)`. Signature verification happens automatically — the call reverts if fewer than 3 valid `redstone-primary-prod` signers are present in the calldata.

### Integration — Keeper script

```js
const { WrapperBuilder } = require("@redstone-finance/evm-connector");
const { ethers } = require("hardhat");

const contract = await ethers.getContractAt("EventlyMarkets", MARKETS_ADDRESS);

const wrapped = WrapperBuilder
  .wrap(contract)
  .usingDataService({
    dataServiceId: "redstone-primary-prod",
    uniqueSignersCount: 3,
    dataFeeds: [feedId],  // e.g. "ETH"
  });

await wrapped.resolveMarketWithOracle(marketId, evidenceHash);
```

### Authorized signers

The contract hardcodes 5 `redstone-primary-prod` signer addresses in `getAuthorisedSignerIndex()`. Minimum threshold is 3 (`getUniqueSignersThreshold()`). Any call with fewer valid signatures will revert.

### Encoding price feed IDs

The `priceFeedId` parameter in `createOracleMarket` is `bytes32`. Encode it as a right-padded ASCII string:

```ts
import { padHex, toHex, stringToBytes } from "viem";

const feedId = padHex(toHex(stringToBytes("ETH")), { size: 32, dir: "right" });
```

### Strike price precision

Strike prices use **8 decimal places** (same as Redstone USD feeds):

| Value    | Encoded          |
| -------- | ---------------- |
| $3,000   | `300000000000`   |
| $100,000 | `10000000000000` |
| $0.50    | `50000000`       |

***

## Drand BLS12-381 VRF (MegaETH Native)

MegaETH exposes a native precompile for verifying **Drand quicknet BLS12-381** randomness proofs. evently uses this for:

1. **Monthly dispute lottery** — `distributeMonthlyDisputeRewards(month, vrfProof, vrfMessage)` draws a single winner-takes-all
2. **Weekly Lucky Trader raffle** — `drawLuckyTrader(week, vrfProof, vrfMessage, bonusAmount)` draws one winner from that week's active traders

### Interface

```solidity
interface IDrandVerifier {
    function verify(bytes calldata proof, bytes calldata message) external view returns (bool);
}
```

The contract calls `IDrandVerifier(drandVerifier).verify(vrfProof, vrfMessage)` and reverts if the proof is invalid.

### Winner derivation

```solidity
uint256 winnerIndex = uint256(keccak256(vrfProof)) % count;
address winner = entries[winnerIndex];
```

The VRF proof itself is the source of entropy — it is deterministic given the Drand round and cannot be manipulated by the caller.

### Admin setup

Set the precompile address before any draw:

```solidity
setDrandVerifier(0x...precompile...);
```

The address is network-specific. Confirm the MegaETH Drand precompile address from the official MegaETH documentation before deployment.

### Fetching a Drand proof (off-chain)

```js
// Fetch latest quicknet round
const res = await fetch("https://api.drand.sh/52db9ba70e0cc0f6eaf7803dd07447a1f5477735fd3f661792ba94600c84e971/public/latest");
const { round, signature } = await res.json();

// vrfProof = signature (hex-encoded BLS12-381 G1 point)
// vrfMessage = round number encoded as 32-byte big-endian uint
const vrfProof = "0x" + Buffer.from(signature, "base64").toString("hex");
const vrfMessage = ethers.utils.hexZeroPad(ethers.utils.hexlify(round), 32);
```

# Security Overview

## Approach

evently's security process is structured in three phases:

```
Phase 1 — AI audits (7 engines) + automated tools    ← completed
Phase 2 — Professional third-party audit              ← two independent firms scheduled
Phase 3 — Ongoing monitoring + bug bounty             ← post-launch
```

All findings, fixes, and the contracts reviewed at each stage are documented publicly in this documentation and in the GitHub repository.

***

## AI Security Audits

All evently contracts underwent multi-round security review using **7 AI engines** with a 3-round methodology (Systematic review → Economic analysis → Triage). The contracts reviewed are: **EventlyProfiles.sol v1.3** and **EventlyMarkets.sol (LMSR, b=200)**.

| AI Tool         | Contracts                      | Findings | Status                       |
| --------------- | ------------------------------ | -------- | ---------------------------- |
| Claude Opus 4.6 | EventlyMarkets · Profiles v1.3 | 6        | All resolved or acknowledged |
| GPT-4o          | EventlyMarkets · Profiles v1.3 | 13       | All resolved or acknowledged |
| Gemini 1.5 Pro  | EventlyMarkets · Profiles v1.3 | 9        | All resolved or acknowledged |
| Grok (xAI)      | EventlyMarkets · Profiles v1.3 | 6        | All resolved or acknowledged |
| DeepSeek R1     | EventlyMarkets · Profiles v1.3 | 7        | All resolved or acknowledged |
| Qwen3.5         | EventlyMarkets · Profiles v1.3 | 4        | All resolved or acknowledged |
| Perplexity      | EventlyMarkets · Profiles v1.3 | —        | All resolved or acknowledged |

**All 7 AI engines reviewed EventlyMarkets (LMSR).** Key cross-tool findings documented in [Consolidated AI Audit](/security/pre-audit-consolidated).

***

## Automated Tool Scans

22 automated security tools completed, following the methodology recommended by [z0r0z/majeur](https://github.com/z0r0z/majeur). Individual reports are linked in the Audit Reports section.

***

## Third-Party Audits

Two independent professional audits are scheduled for Q2 2026. Firms were selected based on availability, scope fit, and budget. Formal audit reports will be published here upon completion.

***

## Security Properties

### Reentrancy

Fund-moving functions use a custom inline `nonReentrant` mutex (`_locked` flag — not the OZ import). CEI (Checks-Effects-Interactions) enforced throughout. All AI audits confirmed: **0 reentrancy vulnerabilities found in active paths**. `nonReentrant` added to `resolveMarket`, `cancelMarket`, `slashMarket`, `claimCreatorFees`, `reclaimCancelledOrder` .

### Pull Payment

All payouts use pull-payment: winners call `redeemWinnings()`, cancelled-market holders call `claimCancelRefund()`, creators call `claimCreatorFees()`. No push to arbitrary addresses. Lazy refund for cancelled CLOB orders via `reclaimCancelledOrder()`.

### Treasury Resilience

Treasury fees accumulate in `treasuryBalance` (no external transfer on every trade). Withdrawals are two-step with a 24-hour timelock: `requestTreasuryWithdrawal()` → wait 24h → `executeTreasuryWithdrawal()`. Admin can cancel before execution. Prevents rug-pull .

### Access Control

| `onlyAdmin`           | Admin multisig                            | Slash, pause, ban, whitelist management, treasury, admin cancel |
| `onlyDisputeResolver` | Dedicated resolver address                | `settleDispute()` only                                          |
| `onlyMarketCreator`   | `marketCreatorWhitelisted[addr]` or admin | `createMarket`, `createImportedMarket`                          |
| `onlyWhitelisted`     | `whitelisted[addr]`                       | Trading functions (beta only; disabled at public launch)        |
| `whenNotPaused`       | —                                         | All trading and market creation                                 |

Admin and `disputeResolver` are **separate roles** — admin cannot unilaterally settle disputes. Resolver pool address changes are also timelocked (24h).

### Emergency Controls

**Pause:** `pause()` (admin only). Blocks all trading and market creation via `whenNotPaused`. Auto-expires after **72 hours** (`MAX_PAUSE_DURATION`). After expiry, anyone can call `unpause()` — prevents permanent lockout by a compromised admin key.

**Ban:** `banAddress(addr)` / `unbanAddress(addr)` (admin only). Banned addresses cannot call any market function. Used to remediate griefing addresses without affecting other users.

**Admin Cancel Orders:** `adminCancelOrders(orderIds[])` — force-cancels resting CLOB orders; escrowed funds returned to original owners. Used when a banned address has open orders.

### Mandatory Evidence Hashes

Both `resolveMarket()` and `settleDispute()` require a non-zero `bytes32 evidenceHash`. Emitted via `ResolutionEvidence(marketId, submitter, hash)` event. Provides an immutable on-chain audit trail linking every resolution to an off-chain evidence document.

### Mandatory Resolution

`cancelMarket` is blocked if the market has any trading activity (`totalVolume > 0` or active resting orders) until `resolutionDeadline` passes. Prevents creators from quietly cancelling active markets to avoid adverse outcomes.

### LMSR Solvency

Mathematically proven by construction: `poolBalance + subsidyDeposited >= total winning shares` at all times. The LMSR cost function is monotone — buying shares always increases the pool by at least the payout obligation.

### conditionId Validation

Imported Polymarket condition IDs are validated as exactly 66 characters, `0x`-prefixed, lowercase hex `[0-9a-f]` only. Prevents case-aliased duplicates from bypassing the `keccak256` deduplication guard.

### No Upgradeability

Contracts are immutable. No proxy pattern. Any upgrade requires a new deployment with migration.

## Known Design Choices

| Item                                | Decision            | Rationale                                                                                          |
| ----------------------------------- | ------------------- | -------------------------------------------------------------------------------------------------- |
| Single `disputeResolver`            | Centralization risk | Separate from admin; planned upgrade to validator council post-TGE (Megavalidators NFT governance) |
| Fixed 2.5% fee                      | Not configurable    | Prevents admin fee manipulation; constants audited                                                 |
| Trader whitelist disabled at launch | Open trading        | Creator whitelist always active as quality gate                                                    |
| LMSR b = 200 USDm fixed             | Not per-market      | Simplifies solvency proof; configurable b roadmapped for V4                                        |
| Creator collateral 50 USDm          | Fixed               | Dynamic collateral scaling deprioritized; admin ban provides secondary deterrent                   |
| ERC-1155 pre-resolution transfers   | No restriction hook | Positions technically transferable. `optionSupply` tracks total minted, not per-wallet.            |
| Admin multisig                      | Gnosis Safe         | Planned post-raise. Single-sig admin is acknowledged risk during beta.                             |

## Cross-Tool Consensus — Acknowledged by Design

The following findings were raised by multiple tools independently. All are acknowledged design decisions, not vulnerabilities.

## Reentrancy Analysis (Consolidated)

All 7 audits confirmed zero exploitable reentrancy in active trading paths.

| Function group                                            | Guard                |

| `placeOrder`, `sellToAMM`, `cancelOrder`                  | `nonReentrant` + CEI |
| `redeemWinnings`, `claimCancelRefund`, `claimCreatorFees` | `nonReentrant` + CEI |
| `disputeMarket`, `settleDispute`                          | `nonReentrant` + CEI |
| `resolveMarket`, `cancelMarket`, `slashMarket`            | `nonReentrant` + CEI |
| `reclaimCancelledOrder`                                   | `nonReentrant` + CEI |
| All state-mutating admin functions                        | `nonReentrant` + CEI |

**Consensus: 0 reentrancy vulnerabilities in active paths.**

***

## Economic Analysis — LMSR Solvency

**Verdict: SOLVENT — proven by construction.**

* `poolBalance + subsidyDeposited = C(q) ≥ max(q[i]) = q_winner` at all times
* 1 winning share redeems for exactly 1 USDm — no pro-rata rounding
* CLOB fills use escrowed USDm (BUY) or escrowed shares (SELL) — AMM pool unaffected by CLOB matching
* Cancel refund pool: `poolBalance + subsidyDeposited` — subsidy recoverable by shareholders

**No economic attack vector identified by any of the 7 engines.**

## Architecture Overview

EventlyMarkets combines three trading layers:

| Layer                 | Role                                                                    |
| --------------------- | ----------------------------------------------------------------------- |
| LMSR AMM (b=200 USDm) | Permanent market maker; baseline liquidity; market maker of last resort |

# Claude Opus 4.6

**Tool:** Claude Opus 4.6 (Anthropic) **Type:** 3-round AI audit (Systematic → Economic → Triage) **Contracts reviewed:** EventlyProfiles.sol · EventlyMarkets.sol (LMSR b=200 + CLOB bids/asks) **Chain:** MegaETH (Chain ID 4326) — Solidity ^0.8.20 **Dependencies:** OpenZeppelin ERC-1155 / SafeERC20, PRBMath SD59x18 **Date:** March 2026 **Status:** Complete

***

## Summary

Full audit of EventlyMarkets covering the LMSR AMM, CLOB order book (bids & asks), ERC-1155 position system, dispute mechanism, and collateral/fee flows. All previously identified vulnerabilities (F-02, A-03, F-DS-M02, R2-2, L-01) confirmed patched. Four additional findings (GROK-M01, GPT-R3-3, GROK-L02, QWEN-I03) identified and resolved. **No production blockers remain.**

## Round 1 — Systematic Vulnerability Scan

### Reentrancy

All external state-mutating functions use `nonReentrant` mutex (`_locked`). CEI (Checks-Effects-Interactions) pattern is correctly followed throughout:

* `placeOrder`: USDm/shares transferred in at top; all state updates before external calls (seller transfers, share transfers, AMM mint)
* `sellToAMM`: quantities and balance decremented, shares burned, \_collectFees called — all before `usdm.safeTransfer`
* `redeemWinnings`: shares burned, balances decremented before transfer
* `claimCancelRefund`: pre-burn snapshot, then burn, then transfer — F-02 fix correctly implemented
* `cancelOrder`: order deactivated, amounts zeroed before `safeTransfer` / `_safeTransferFrom`
* `disputeMarket`: state set before transfer
* `settleDispute`: state fully updated before `usdm.safeTransfer` to disputer
* `resolveMarket`, `cancelMarket`, `slashMarket`: now protected by `nonReentrant` (L-01 fix) ✅

**No reentrancy vulnerabilities found.**

### Access Control

* `onlyAdmin`: correctly restricts `withdrawTreasury`, `transferAdmin`, `settleDispute`, `slashMarket`, `setResolverPoolAddress`, `setFees`, `burnLosingShares`
* `onlyWhitelisted`: correctly gates `placeOrder`, `sellToAMM`, `disputeMarket`, `createMarket` when `whitelistEnabled = true`
* `transferAdmin`: zero-address check present ✅
* `resolveMarket`: checks `msg.sender == m.creator` and timing bounds ✅
* `claimCreatorFees`: requires `Finalized` status — implicitly blocks `Disputed` (R2-2 fix) ✅

**L-02 (Low):** Single admin key is a centralization risk. Admin can call `slashMarket`, drain treasury, override dispute outcomes, and trigger `burnLosingShares`. Mitigated by planned Gnosis Safe multisig post-raise. Acknowledged design tradeoff.

### Integer Arithmetic

* Solidity ^0.8.20 built-in overflow protection ✅
* LMSR math uses PRBMath SD59x18 — audited fixed-point library ✅
* Fee calculations: `(amount * BPS) / 10000` — correct order, no precision loss beyond 1 wei per operation ✅
* `redeemWinnings` payout: `payout = shares` (1 share = 1e18 = 1 USDm) — no rounding, exact ✅
* `claimCancelRefund` pro-rata: `(poolBalance * userTotal) / allTotal` — standard floor division, last redeemer may receive 1 wei less. Acceptable.

**L-03 (Low):** In `quoteBuy`, the binary search upper bound is `maxQ = 26000e18` (\~26,600 USDm worth of shares per tx). Derived from the SD59x18 `exp` overflow limit at `q/b ≈ 133`. Documented in NatSpec.

### Token Handling

* `SafeERC20` used for all USDm transfers ✅
* ERC-1155 shares: minted on AMM buy, burned on sell/redeem, `optionSupply` tracking mirrors ERC-1155 supply correctly
* CLOB fills: shares transferred from contract escrow (ASK) or minted (AMM BUY) to buyer

**L-04 (Low):** `optionSupply[marketId][opt]` is manually maintained alongside `_mint`/`_burn`. Peer ERC-1155 transfers via `safeTransferFrom` do not update `optionSupply` — it tracks total minted supply, not per-wallet balances. The math in `redeemWinnings` (uses `balanceOf`) and `claimCancelRefund` (uses `optionSupply`) remains correct by design. Acknowledged.

### CLOB Order Book

The CLOB replaces the previous P2P sell-only book with full bids and asks:

* **Price-time priority**: orders sorted by price first (ascending for asks, descending for bids), FIFO within same price using `placedAt` timestamp
* **Immediate matching**: `placeOrder` matches against the opposite book before creating a resting order
* **Dead entry cleanup (F-DS-M02 fix)**: `_cleanBook` called immediately on `cancelOrder`, preventing permanent DoS of a book
* **Book cap**: `MAX_ORDERS_PER_BOOK = 200` per (market, option, side) pair — griefing cap maintained ✅
* **AMM fallback**: unmatched BUY budget routed to LMSR AMM — ensures liquidity always available

**No CLOB-specific vulnerabilities found.**

### LMSR Math Verification

The cost function `C(q) = b × ln(Σ exp(q[i]/b))` is correctly implemented in `_lmsrCost`. Verified properties:

* **Initial price symmetry:** At `quantities = [0,0,...,0]`, all options have price 1/n ✅
* **Price sum invariant:** `Σ P(i) = 1` always ✅
* **Monotonicity:** Buying option i increases P(i), decreases P(j≠i) ✅
* **Solvency:** `poolBalance + subsidyDeposited ≥ total winning shares` — proven by LMSR cost function bound ✅

***

## Round 2 — Economic Attack Analysis

### LMSR Solvency

**Proof:** `poolBalance + subsidyDeposited = C(q_final) ≥ quantities[winning_opt]` = total winning shares minted. `redeemWinnings` draws from `poolBalance` first, then `subsidyDeposited`. **SOLVENT by mathematical guarantee.** ✅

### F-02 Fix Verification

`claimCancelRefund` snapshots `allTotal` before burning. Multiple sequential claimers cannot extract more than `poolBalance`. ✅

### F-DS-M02 Fix Verification

`cancelOrder` now calls `_cleanBook` immediately after marking the order inactive. Dead entries are removed on the same transaction. An attacker who fills a book with 200 orders and cancels them all will see the book length drop to 0 — no permanent DoS possible. ✅

### R2-2 Fix Verification

`claimCreatorFees` requires `m.status == MarketStatus.Finalized`. While a market is `Disputed`, its status is `Disputed` — not `Finalized` — so the require reverts. No front-run path exists: the creator cannot claim fees during the dispute window. ✅

### Fee Accounting

`_collectFees` correctly splits into creator, treasury, and resolver cuts. Admin markets redirect creator cut to treasury. Creator fees locked until finalization. On slash or lost dispute: `creatorAccruedFees` zeroed to treasury. ✅

**M-01 (Medium) — Multi-ledger accounting:** In `sellToAMM`, `poolBalance -= grossUsdm` before `_collectFees` returns `netUsdm`. Fees (grossUsdm - netUsdm) are credited to treasury/resolver/creator balances but not deducted separately from poolBalance — this is correct since `poolBalance` is reduced by gross. The implicit invariant `poolBalance + treasuryBalance + resolverPoolBalance + Σ creatorAccruedFees = total USDm held` should be validated by formal invariant tests. No discrepancy found.

### Auto-Burn Economic Model

`burnLosingShares` is callable by admin only, 24h after finalization. The BURN\_DELAY matches DISPUTE\_WINDOW, so winning and losing determination is always final before the burn. The keeper-driven model is appropriate for MegaETH's environment. ✅

***

## Round 3 — Adversarial Triage

### Can funds be stolen?

* `withdrawTreasury`: `onlyAdmin`, draws from `treasuryBalance` only ✅
* `redeemWinnings`: burns shares before transfer, subsidy drawn only for shortfall ✅
* `claimCancelRefund`: pre-burn snapshot prevents over-extraction ✅
* `claimCreatorFees`: `onlyCreator`, requires `Finalized`, one-time flag ✅
* `cancelOrder`: returns only escrowed funds to `msg.sender == o.maker` ✅
* `settleDispute`: slash mechanism intended; only activates on dishonest resolution ✅
* `burnLosingShares`: `onlyAdmin`, burns worthless losing shares only — no USDm movement ✅

**Verdict: No direct fund theft path found.**

### Can the contract be bricked?

* `transferAdmin(address(0))`: blocked ✅
* `_cancelAllOrders` in `resolveMarket`/`cancelMarket`/`slashMarket`: max 200 asks + 200 bids × 4 options = 1,600 iterations. Safe on MegaETH. **L-05 (Low):** On L1-like environments this could hit gas limits; noted for any future multi-chain deployment.
* LMSR `exp` overflow: `quoteBuy` cap at 26,000e18. ✅
* CLOB dead entries: cleaned immediately on cancel — no permanent DoS possible (F-DS-M02 fix). ✅

**Verdict: No bricking path found.**

### ERC-1155 Transfer Hook

No `_beforeTokenTransfer` override. Shares are freely transferable. `redeemWinnings` uses `balanceOf` (actual balance) so peer transfers don't break redemption. `optionSupply` tracks total minted, not per-wallet — by design. ✅

**I-01 (Info):** Empty ERC-1155 URI — no metadata for position tokens. URI to be added pre-deployment.

**Tool:** GPT-5.3\
**Type:** 3-round AI audit (Systematic → Economic → Triage)\
**Contracts reviewed:** EventlyProfiles.sol · EventlyMarkets.sol (LMSR b=200 + CLOB bids/asks)\
**Chain:** MegaETH (Chain ID 4326) --- Solidity ^0.8.20\
**Date:** March 2026\
**Status:** Complete

***

## Summary

The evently system is generally well-structured and follows several good security practices (custom reentrancy guard, CEI ordering, pull-payments fallback, and fee accounting). No critical reentrancy or solvency vulnerabilities were identified.

However **3 notable findings** were discovered: - **1 High severity** - **2 Medium severity**

The **High severity issue** relates to a dispute settlement imbalance in `EventlyMarkets` that can lead to protocol-level token loss.

***

## Findings

F-02 Medium EventlyMarkets Creator can By design resolve market\
dishonestly\
before dispute

### F-03 Medium EventlyProfiles Username case Fixed — \_toLower() applied normalization inconsistency

***

## Round 1 --- Systematic Review

### Reentrancy

EventlyMarkets implements a manual reentrancy lock (`_locked`) protecting external entrypoints such as:

* `buyShares`
* `sellShares`
* `placeBid`
* `placeAsk`
* `settleDispute`
* `claimWinnings`
* `claimRefund`
* `claimSlashedRefund`

Example:

```solidity
pendingWithdrawals[msg.sender] = 0;
usdm.safeTransfer(msg.sender, amt);
```

State changes occur before external calls, preventing reentrancy exploits.

Verdict: **Safe implementation**

***

### Access Control

Key protected functions:

* `pause`
* `unpause`
* `setDisputeResolver`
* `settleDispute`
* `distributeMonthlyDisputeRewards`

Profiles contract uses `onlyGame` modifier, and Markets contract uses `onlyAdmin`.

Market resolution is controlled by the market creator:

```solidity
require(msg.sender == m.creator, "Only creator");
```

This is a trust assumption rather than a vulnerability.

***

### Integer Arithmetic

Solidity ^0.8 prevents overflow.

Examples reviewed:

```solidity
(uint256 distributablePool * userBet) / winningPool
```

```solidity
(treasuryGain * DISPUTE_REWARD_SHARE_BPS) / 10000
```

Dust may occur due to integer division but is negligible.

Verdict: **Safe**

***

### Logic & State

#### Username normalization issue

Profile creation:

```solidity
usernameTaken[_username] = true;
usernameToAddress[lowerUsername] = msg.sender;
```

Case-sensitive duplicates possible (`Alice` vs `alice`), leading to inconsistent lookups.

***

### Denial of Service

CLOB bid/ask arrays are bounded by practical market size. `getLeaderboard` and other view functions iterate across all players but are **view-only**, therefore safe.

***

### Front-running / MEV

Expected in:

* Prediction market betting
* CLOB order matching

No exploitable contract logic issues found.

***

## Round 2 --- Economic Analysis

### Market Solvency

LMSR invariant maintained via `b` parameter (cost function bounded). Creator collateral posted at market creation ensures resolution incentives exist.

Verdict: **Markets remain solvent.**

***

### Dispute Economics

Disputes require 50 USDM collateral from disputer.

```solidity
DISPUTE_COLLATERAL = 50e18
```

Economic protection against frivolous disputes exists.

***

### Referral Sybil Vectors

Mitigation exists:

```
REFERRAL_ACTIVATION_THRESHOLD = 0.01 ether
```

Attack still possible but economically inefficient.

***

### Market Creator Advantage

Creator resolves markets but disputes require collateral (50 tokens), creating economic protection.

***

### Treasury Risks

Treasury controlled by admin key.

Worst-case scenario: treasury drained but markets continue operating.

***

## Round 3 --- Triage

### F-01 --- Dispute payout imbalance (High)

Bug:

```solidity
usdm.safeTransfer(m.disputer, DISPUTE_COLLATERAL + 25e18);
```

Contract only receives 50 tokens but sends 75, causing protocol loss.

#### Fix

```solidity
function settleDispute(uint256 _marketId, bool _creatorWasRight) external onlyAdmin {
    Market storage m = markets[_marketId];
    require(m.status == MarketStatus.Disputed, "Not disputed");

    if (_creatorWasRight) {
        treasuryBalance += DISPUTE_COLLATERAL;
    } else {
        usdm.safeTransfer(m.disputer, DISPUTE_COLLATERAL);
        m.winningOption = m.disputeOption;
        m.creatorCollateralReturned = true;
        m.creatorFeePaid = true;
    }

    m.status = MarketStatus.Finalized;
    _emitFinalized(_marketId);
}
```

***

### F-02 --- Dishonest creator resolution

Creator can resolve incorrectly before dispute.

Classification: **Design Tradeoff**

***

### F-03 --- Username normalization bug

Recommended fix:

```solidity
string memory lowerUsername = _toLower(_username);

require(!usernameTaken[lowerUsername], "Username taken");

usernameTaken[lowerUsername] = true;
usernameToAddress[lowerUsername] = msg.sender;
```

## Round 1 — Systematic Scan

### Reentrancy, Access Control, Token Handling, and Math

The contract uses `nonReentrant` on core functions (`buyShares`, `sellToAMM`, `createSellOrder`, `disputeMarket`, `settleDispute`, `claimCreatorFees`, `redeemWinnings`, `claimCancelRefund`). However, `cancelMarket` and `closeBetting` lack this modifier. While these specific functions don't perform external calls before state changes, it is a best practice for consistency. (**L-01**)

`onlyAdmin` and `onlyWhitelisted` modifiers are correctly applied to sensitive functions. Solidity 0.8.20 provides native overflow protection. `SafeERC20` is used for all USDm transfers. The cost function `_lmsrCost` correctly implements `C(q) = b × ln(Σ exp(q[i]/b))`. PRBMath SD59x18 is used for fixed-point `exp` and `ln` operations.

***

## Round 2 — Economic Attack Analysis

### Solvency, Fees, and Order Book

The contract relies on `subsidyDeposited + poolBalance ≥ total winning shares`. The subsidy is calculated as `b × ln(n)`, which covers the worst-case transition from uniform to concentrated probability.

Fees are collected during `buyShares` and `sellToAMM`. A notable design characteristic: fees are taken from the `remaining` amount in `buyShares` *before* the AMM quote, effectively reducing the net USDm passed to the LMSR cost function. (**H-02**)

The `MAX_ORDERS_PER_BOOK` cap (A-03 fix) is correctly implemented and prevents order book flooding.

***

## Round 3 — Adversarial Triage

### C-01 — Potential Insolvency via P2P Redemptions \[RESOLVED / FALSE POSITIVE]

In `redeemWinnings`, if `payout > poolBalance`, the contract draws from `subsidyDeposited`. However, `poolBalance` only tracks net USDm from AMM trades. When a buyer fills a P2P sell order in Phase 1 of `buyShares`, the USDm is sent directly to the seller — but the buyer receives ERC-1155 shares that are indistinguishable from AMM-minted shares and are equally redeemable against the contract's pool.

If significant volume goes through P2P orders, the physical USDm backing those shares has already left the contract. The `poolBalance` does not account for this gap, and the subsidy alone may not cover the shortfall.

**Recommended Fix:** Implement a redemption reserve that retains a portion of P2P sales in `poolBalance`, or require that total USDm in the contract always equals the maximum possible payout:

```solidity
// Suggestion: explicit solvency check on buy
require(
    usdm.balanceOf(address(this)) >= totalMintedShares + treasuryBalance + resolverPoolBalance,
    "Solvency check failed"
);
```

### H-01 — P2P vs AMM Price Arbitrage / Griefing

`buyShares` fills P2P sell orders before routing to the AMM. If a P2P order is priced significantly above the current AMM implied probability (e.g., 0.99 USDm when AMM price is 0.50 USDm), a buyer calling `buyShares` is forced to fill the expensive P2P order first. While `_minShares` slippage protection helps, the execution is economically sub-optimal.

**Recommended Fix:** Compare the cheapest P2P order price against the current LMSR `getPrice` before filling, and skip P2P orders priced above AMM:

```solidity
if (o.pricePerShare > getPrice(_marketId, _opt)) { idx++; continue; }
```

### M-01 — `closeBetting` lacks access control

Any user can call `closeBetting` once the betting deadline has passed. While the function requires the deadline to be expired, allowing any address to trigger state transitions can lead to unexpected bot behavior.

**Recommended Fix:** Restrict `closeBetting` to admin, creator, or a permissioned keeper address.

### M-02 — Fee rounding dust always favors resolver

The `resolverCut = totalFee - creatorCut - treasuryCut` calculation means rounding dust is always absorbed by the resolver pool. Over many trades, this creates a systematic minor imbalance in fee distribution.

**Recommended Fix:** Document this as an explicit design choice, or implement round-robin dust assignment across the three recipients.

**C-01 (Critical):** Potential P2P insolvency — review the `poolBalance` accounting against P2P-settled shares before high-volume deployment. The mathematical LMSR solvency guarantee applies to AMM-minted shares only; P2P fills may create an uncovered gap.

# Perplexity

**Perplexity GPT-5.1 --- Security Report**

**Tool:** Perplexity GPT-5.1\
**Type:** 3-round AI audit (Systematic → Economic → Triage)\
**Contracts reviewed:** EventlyProfiles.sol · EventlyMarkets.sol (LMSR b=200 + CLOB bids/asks)\
**Chain:** MegaETH (Chain ID 4326) --- Solidity ^0.8.20\
**Date:** March 2026\
**Status:** Complete

**Summary**

Across the two contracts, I found 1 High, 2 Medium, 3 Low, and several Informational issues, mostly around access control, minor logic bugs, and DoS/UX footguns rather than direct fund theft vectors. EventlyProfiles handles reentrancy and pull-payments well. EventlyMarkets exposes meaningful griefing, fee-routing, and accounting risks in its AMM and order book logic. No "instant full-treasury drain" production blocker appears, but the High issue and one Medium in EventlyMarkets are practical blockers before mainnet deployment.

**Findings**

***

**ID** **Severity** **Contract** **Title** **Status**

***

F1 High EventlyMarkets Incomplete nonReentrancy coverage on ERC20/1155 flows Implemented — nonReentrant on all external state-mutating functions

F2 Medium EventlyProfiles setAuthorizedCaller ignores \_authorized argument Acknowledged

F3 Medium EventlyMarkets Order book unbounded loops enable griefing/DoS Fixed — MAX\_ORDERS\_PER\_BOOK = 200

F4 Medium EventlyMarkets Weak validation of market parameters (deadlines, options) Implemented — requires bettingDeadline>now, resolutionDeadline>betting, option length checks

F5 Low EventlyProfiles Leaderboard O(n²) iteration may become unusable at scale Acknowledged

F6 Low EventlyMarkets Fee accounting edge cases on cancel / slash / finalize Implemented — creatorAccruedFees zeroed to treasury on slash/dispute loss

F7 Low EventlyMarkets Potential dust and rounding issues in LMSR share math Acknowledged

F8 Informational EventlyProfiles Username mapping is case-normalized but external key isn't By design

### F9 Informational EventlyMarkets Market creator informational advantage is inherent By design

**Round 1 --- Systematic Review**

**1. Reentrancy**

* EventlyProfiles.sol
  * Only claimReferralEarnings is nonReentrant and performs CEI before sending ETH to msg.sender, which is correct.
  * withdrawFees sends full balance to owner without nonReentrant, but the function cannot be reentered from within this contract because there are no callbacks here; still, making it nonReentrant would be slightly safer defense in depth.
* EventlyMarkets.sol
  * Declares its own \_locked guard, but you need to verify every function that moves USDm (AMM buy/sell, create/cancel orders, redeem, resolve/finalize) is actually marked nonReentrant and respects CEI.
  * Because EventlyMarkets is an ERC1155, callbacks like onERC1155Received on external receivers (when transferring positions) could open up cross-contract reentrancy if such transfers are permitted before finalization. The spec says ERC-1155 positions are non-transferable pre-resolution "by design," but you must ensure safeTransferFrom is disabled or overridden accordingly.

Finding F1 (High):\
If any of the key flows (e.g., AMM trade functions, redeemWinningShares, cancelSellOrder) lack nonReentrant while performing external ERC20 transfers or 1155 mints/burns plus internal accounting, you have a concrete reentrancy surface that could be abused to mint extra shares or drain the USDm pool. I treat this as High until a complete pass confirms all such functions are guarded and CEI-compliant.

**2. Access Control**

* EventlyProfiles.sol
  * setGameContract is owner-only, update\* and game-only mutating functions are protected with onlyGame as expected.
  * authorizedCallers is intended as an owner-settable whitelist for recordSwap, but setAuthorizedCaller(address \_caller, bool \_authorized) ignores \_authorized and always sets the value to true. This prevents revocation and could accidentally re-enable a compromised address. (F2, Medium)
* EventlyMarkets.sol
  * Uses admin as privileged account; must ensure functions like slashMarket, cancelMarket, or any treasury-draining path are properly onlyAdmin-gated. From the context, the presence of creator collateral and treasury balance implies critical admin-only flows.
  * Whitelist logic (whitelistEnabled, whitelisted) plus invite codes provide optional access gating; ensure that any bypass (e.g., admin markets) is explicit and documented.

**3. Integer Arithmetic**

* All contracts compile under Solidity ^0.8.20, so arithmetic overflows/underflows revert by default.
* EventlyProfiles.sol
  * Points for swaps (\_volumeUsdCents \* SWAP\_POINTS\_PER\_USD\_CENT) / 100 are straightforward; the \_volumeUsdCents <= 1,000,000 guard removes extreme multipliers.
* EventlyMarkets.sol
  * LMSR math will combine poolBalance, virtualPools, and SHARE\_UNIT (1e18) to calculate shares and price. These divisions can introduce dust; some residual USDm or shares may become unclaimable. That is a Low severity accounting issue unless it accumulates significantly (F7).

**4. Logic & State**

* EventlyProfiles.sol
  * Username uniqueness is enforced on lowercase, while the stored username preserves original case. This is a good anti-squatting pattern, but external callers querying usernameToAddress must always pass lowercased string; the contract's own \_resolveReferrer currently indexes with the raw \_referrerUsername without lowercasing, which bypasses lowercasing and makes those lookups case-sensitive, undermining the design (Informational F8, since UX, not funds).
* EventlyMarkets.sol
  * Market lifecycle: Active → BettingClosed → Resolved/Disputed → Finalized/Cancelled/Slashed, with creator collateral flags and fee flags.
  * Potential issues:
    * If deadlines or statuses are not strictly checked in all entry points, you can buy after bettingDeadline or redeem before Finalized. (F4, Medium)
    * Without careful handling, creatorCollateralReturned and creatorFeePaid might be toggled multiple times or not at all if resolution paths diverge (e.g., cancelled vs slashed). (F6, Low)

**5. Denial of Service**

* EventlyProfiles.sol
  * \_getLeaderboard uses nested loops over allPlayers to compute a top-k leaderboard in O(n²) time in the worst case. As allPlayers grows large, those view calls may become too expensive to execute on-chain, effectively DoS'ing the function (F5, Low). This affects only visibility, not funds.
* EventlyMarkets.sol
  * Order book uses arrays of order IDs per (marketId, optionIndex), and insertion maintains sorted-by-price order by shifting elements in a nested fashion. Cancelling orders likely traverses arrays to remove IDs. This is prone to gas-heavy execution and griefing: a user can create many tiny orders to bloat the order book and make trades or cancellations revert from gas usage (F3, Medium).

**6. Front-running / MEV**

* EventlyMarkets.sol
  * AMM trades and P2P fills are deterministic given the order book; MEV can reorder trades and fills but cannot break invariants if functions are coded correctly.
  * If there is any check like "fill cheapest order, then mint from AMM," MEV can place and cancel orders around a user's transaction or front-run with their own fills to capture surplus. That is more economic than technical, and belongs in Round 2.

**Round 2 --- Economic Analysis**

**Market Solvency (EventlyMarkets)**

* LMSR invariant is maintained via the `b` parameter. Creator collateral posted at market creation ensures resolution incentives exist.
* Winnings are paid from poolBalance; creator fees and treasury fees come only from trade volume. No flow appears to create promises exceeding available USDm, so insolvency risk is low provided accounting is consistent across all lifecycle states.

**Referral Sybil Vectors**

* Referrals require referred user to reach REFERRAL\_ACTIVATION\_THRESHOLD before rewards are credited, limiting trivial sybil farming.
* However, a single controller can spin many addresses, each legitimately reaching the threshold, to farm referral rewards; that is economically bounded by the fee structure and not a contract-level vulnerability.
* Profiles store referral relationships on-chain and allow only a single referrer per player; there is no on-chain limit to the number of referrals per referrer, which is intentional.

**Market Creator Insider Advantages (EventlyMarkets)**

* Creators receive a fee share of all trade volume for their market, but those fees are paid only after finalization, and collateral is locked to incentivize honest resolution.
* Creators can choose question wording, resolution criteria, resolution window, and they may have informational advantage; that is inherent to prediction markets. The main concern is whether they can:
  * Resolve in their favor despite objective outcome, or
  * Stall resolution to keep fees or block redemptions.
* The presence of Disputed and Slashed statuses plus DISPUTE\_COLLATERAL suggests a mechanism for disputer challenges; if admin has unilateral power to slash or finalize, governance centralization is high and may be a social, not technical, risk (F9, Informational).

**AMM Manipulation Vectors (LMSR)**

* Prices come from the LMSR cost function parameterized by `b=200`; if the liquidity parameter is not adjusted arbitrarily by admin, creator has no special price-manipulation ability beyond trading like anyone else.
* If any admin/creator-only function can directly mutate poolBalance or virtual pool state without corresponding share mint/burn, that is a latent rug vector; ensure only trades and resolution update these fields.
* Fee structure is symmetric on buy and sell; users cannot create cycles that generate net profit solely from fees unless rounding errors are exploitable (F7).

**Order Book Griefing (CLOB)**

* Sorted arrays for order IDs per option mean that:
  * Creating many small orders at extreme prices forces expensive insertions.
  * Canceling or filling orders likely needs scanning and shifting arrays.
* An attacker can spam a market's order book to the point where legitimate order placements or fills hit the gas limit and revert, effectively DoS'ing that market (F3, Medium). This is a credible griefing vector, not directly profitable but harmful.

**ERC-1155 Position Trading Edge Cases**

* ERC-1155 positions are non-transferable pre-resolution "by design," which is good to prevent unauthorized secondary markets before a final outcome.
* After finalization, redemption of winning shares must burn the correct amount and pay pro-rata USDm; losing shares become worthless. The tricky cases are:
  * Partial redemptions leaving dust shares;
  * Rounding such that last redeemer receives disproportionate or zero payout.
* There's no clear double-spend path if burning happens before transfer of funds (CEI), but dust and rounding (F7) can produce unintuitive payouts.

**Treasury Failure Scenarios**

* EventlyProfiles.sol:
  * withdrawFees sends all ETH in Profiles to owner; if owner is a contract that reverts or uses too much gas, fees become stuck but this is owner revenue, not user funds.
* EventlyMarkets.sol:
  * Treasury balance is tracked in treasuryBalance alongside creatorAccruedFees and poolBalance; mis-accounting across slash/cancel/finalize could send excess funds to treasury or leave collateral stranded (F6, Low).
  * A failing treasury recipient contract could cause trade functions that immediately forward fees to revert, effectively pausing some markets; using an internal balance then separate withdrawal (like withdrawTreasury) is the correct pattern.

**Round 3 --- Triage**

**F1 --- Incomplete nonReentrancy coverage on ERC20/1155 flows (High, EventlyMarkets)**

* Classification: Real Vulnerability
* Rationale: Any function that both updates market accounting and transfers ERC20 or ERC1155 can be a reentrancy target if not guarded and following CEI, especially via ERC1155 receiver hooks or ERC20 tokens with callbacks.
* Fix pattern:

```solidity
uint256 private _locked = 1;
modifier nonReentrant() {
    require(_locked == 1, "Reentrant");
    _locked = 2;
    _;
    _locked = 1;
}
```

* Production blocker: Yes, until you verify and enforce nonReentrant + CEI on all external-call-bearing functions.

**F2 --- setAuthorizedCaller ignores \_authorized argument (Medium, EventlyProfiles)**

* Classification: Real Vulnerability (logic bug)
* Rationale: Owner cannot revoke previously authorized callers; the function's signature is misleading and may cause security assumptions to be wrong.
* Fix:

```solidity
function setAuthorizedCaller(address _caller, bool _authorized) external onlyOwner {
    authorizedCallers[_caller] = _authorized;
}
```

* Production blocker: No, but advisable to fix before relying on dynamic whitelist management.

**F3 --- Order book unbounded loops enable griefing/DoS (Medium, EventlyMarkets)**

* Classification: Design Tradeoff (with real DoS impact)
* Fix: Hard cap number of active orders per (market, option). MAX\_ORDERS\_PER\_BOOK = 200 applied.
* Production blocker: Treated as a blocker for high-volume public deployment. Fixed.

**F4 --- Weak validation of market parameters (Medium, EventlyMarkets)**

* Classification: Real Vulnerability (misconfiguration risk)
* Fix example in createMarket:

```solidity
require(options.length >= MIN_OPTIONS && options.length <= MAX_OPTIONS, "Bad options");
require(bettingDeadline > block.timestamp, "Betting in past");
require(resolutionDeadline > bettingDeadline, "Resolution before betting end");
```

* Production blocker: Medium; misconfigured markets can be stuck but do not directly lose funds if cancellation/refund paths exist.

**F5 --- Leaderboard O(n²) DoS-at-scale (Low, EventlyProfiles)**

* Classification: Design Tradeoff
* Rationale: On large allPlayers, leaderboard views become too expensive; but they are non-critical and view-only.
* Potential improvement: Maintain incremental sorted leaderboards, or compute top lists off-chain.

**F6 --- Fee accounting edge cases (Low, EventlyMarkets)**

* Classification: Design Tradeoff (needs careful review in full code)
* Rationale: Complex states (Cancelled, Slashed, Finalized) with multiple flags (creatorCollateralReturned, creatorFeePaid) plus treasuryBalance and poolBalance easily create mis-accounting paths if not consistently updated.
* Recommendation: Unit-test every lifecycle path to ensure total USDm in equals net of: all user redemptions, creator fees, and treasury fees.

**F7 --- Dust and rounding in LMSR (Low, EventlyMarkets)**

* Classification: Design Tradeoff
* Rationale: Share math with SHARE\_UNIT = 1e18 and integer division will leave small residuals; last redeemer or treasury must be designated as dust recipient.
* Example mitigation: Track unclaimed dust and direct it explicitly to treasury during finalization, and document this behavior.

**F8 --- Username mapping case pitfalls (Informational, EventlyProfiles)**

* Classification: Design Tradeoff / UX issue
* Rationale: Lowercased uniqueness but raw \_referrerUsername lookups can cause confusion; ensure all internal mappings use \_toLower.

**F9 --- Market creator informational advantage (Informational, EventlyMarkets)**

* Classification: By design
* Rationale: Creators choosing questions and resolution criteria will always have some informational advantage; that's inherent to this product class.

# Grok-4

**Tool:** Grok AI Security Auditor (xAI) v2026.03 **Type:** 3-round AI audit (Systematic → Economic → Triage) **Contracts reviewed:** EventlyProfiles.sol · EventlyMarkets.sol (LMSR b=200 + CLOB bids/asks) **Chain:** MegaETH (Chain ID 4326) — Solidity ^0.8.20 **Date:** March 2026 **Status:** Complete

***

## Summary

| Severity  | Count |
| --------- | ----- |
| Critical  | 0     |
| High      | 0     |
| Medium    | 1     |
| Low       | 2     |
| Info      | 3     |
| **Total** | **6** |

**Overall Assessment:** The contract is production-ready with strong safeguards. All previously reported issues (F-02, F-03, A-03) are correctly patched. Core LMSR invariants, CEI patterns, and access controls hold. One medium economic design gap exists around subsidy handling on cancellation.

***

## Round 1 — Systematic Vulnerability Scan

**Reentrancy:** Fully mitigated. Every external-interaction function uses the `nonReentrant` mutex. All state updates precede external calls (strict CEI pattern). ERC-1155 `onERC1155Received`/`onERC1155BatchReceived` are pure selectors with no side effects. SafeERC20 prevents ERC-20 reentrancy vectors.

**Access Control:** Robust. `onlyWhitelisted` (with admin bypass) gates all user actions. `onlyAdmin` protects admin-only paths. Creator-only resolution, dispute, and fee claims are correctly restricted. Whitelist/invite mechanics cannot be bypassed.

**Integer Arithmetic & Rounding:** Safe (Solidity 0.8+ checked arithmetic). Fee calculations use consistent integer division; resolver cut absorbs dust. No overflow paths reachable under realistic quantities (`quoteBuy` caps at 26,000e18 shares per option).

**Token Handling:** Standard OpenZeppelin ERC-1155 + SafeERC20. Escrow in `createSellOrder` and safe mint/burn/transfer patterns are correct. Token ID encoding (`marketId * MAX_OPTIONS + opt`) cannot overflow in practice.

**LMSR Math Correctness:**

* `_lmsrCost`, `getPrice`, `quoteBuy` (binary search), `quoteSell` implement the canonical LMSR formulas.
* Binary search in `quoteBuy` is monotonic and bounded (tolerance 1e15 aligns with `MIN_TRADE`).
* `C(q) = b · ln(Σ exp(qᵢ/b))` invariant holds; PRBMath SD59x18 usage is precise and within documented safe ranges.

No systematic vulnerabilities found in Round 1.

***

## Round 2 — Economic Attack Analysis

**LMSR Solvency:** Guaranteed. At any point `poolBalance + subsidyDeposited = C(current quantities) ≥ q_winner` (because `C(q) ≥ b · ln(exp(q_winner/b)) = q_winner`). `redeemWinnings` draws from pool first, then subsidy, never exceeding available funds. Sequential claims preserve the invariant.

**Fee Accounting:** Accurate 2.5% split (configurable, hard-capped at 5%). P2P and AMM paths both route fees to the correct buckets (`treasuryBalance`, `resolverPoolBalance`, `creatorAccruedFees`). Admin-market creator cut is correctly redirected to treasury.

**Order-Book Safety:** `MAX_ORDERS_PER_BOOK = 200` prevents griefing. Cheapest-first fill logic, partial-fill support, and post-fill `_cleanOrders` compaction are correct. Sell-order escrow and cancellation paths cannot be abused.

**Resolution MEV / Front-running:** Creator resolution window is time-bound and can be overridden by anyone after the resolution deadline. Dispute mechanism + admin settlement provides a credible challenge path. No on-chain MEV vector allows unauthorized resolution.

**Subsidy-Exhaustion / Refund Solvency:** Impossible to exhaust subsidy beyond its mathematical bound. `claimCancelRefund` uses pre-burn total-supply snapshot (F-02 fix) and pro-rata math is sound under sequential calls.

No economic attacks succeed — except the design gap identified in M-01 below.

***

## Round 3 — Adversarial Triage

**Can funds be stolen from `poolBalance` or `subsidyDeposited`?** No. All outflows are either:

* Explicit redemptions/refunds (math-guaranteed)
* Fee withdrawals by authorized parties
* Admin slash/cancel (funds move only to treasury or rightful owners)

Admin-key compromise is the only vector, which is an accepted centralization trade-off.

**Can the contract be permanently bricked?** No. All state transitions are reachable; no dead-end status combinations. Order-book and quantity arrays remain manageable.

**Edge cases simulated:**

* Zero-volume market → cancel succeeds, collateral returned ✅
* Single bettor takes entire liquidity on one side → redeem works ✅
* All bets on losing side + honest resolution → no winning shares, pool locked (see M-01) ✅
* Full dispute flow (creator wins / loses) → accounting correct ✅
* Extreme quantities → `quoteBuy` capacity guard triggers before PRBMath overflow ✅

***

## Findings

### M-01 — Medium

**Title:** `subsidyDeposited` is permanently locked on `Cancelled`/`Slashed` markets

**Contract:** EventlyMarkets.sol

**Description:** The creator (or admin for admin markets) pays the LMSR initial subsidy (`b · ln(n)`) at creation. On `cancelMarket` / `slashMarket`, only `poolBalance` is refunded pro-rata via `claimCancelRefund`. The `subsidyDeposited` value is never included in the refund pool and has no withdrawal path. In finalized markets, any unclaimed winnings leave the remaining `poolBalance + subsidyDeposited` locked forever.

```solidity
// createMarket / createAdminMarket
usdm.safeTransferFrom(..., CREATOR_COLLATERAL + subsidy);
m.subsidyDeposited = subsidy;

// claimCancelRefund — subsidy never included
uint256 refund = (m.poolBalance * userTotal) / allTotal;
m.poolBalance -= refund;

// redeemWinnings is the only path that spends subsidyDeposited
```

**Impact:** Creator permanently loses the subsidy on cancellation. Unclaimed funds in resolved markets are locked indefinitely with no recovery mechanism.

**Recommended Fix:**

1. Include `subsidyDeposited` in the effective refund pool in `claimCancelRefund` (or return it to creator on honest cancel).
2. Consider an optional admin sweep function for unclaimed funds after a long timeout (e.g. 365 days post-finalization).

**Status:** Open

***

### L-01 — Low

**Title:** `quoteBuy` binary search returns slightly conservative share count due to flooring

**Contract:** EventlyMarkets.sol

**Description:** The binary search exits with `sharesOut = lo` where `C(q + lo) - C(q) < _usdm` (tolerance 1e15). The buyer receives marginally fewer shares than the exact net USDm paid would justify.

**Impact:** Negligible (< 0.001 shares per trade). Fully protected by `_minShares` slippage parameter.

**Recommended Fix:** Optional — after binary search, compute exact shares via Newton iteration, or document the 0.001-share tolerance explicitly.

**Status:** Acknowledged

***

### L-02 — Low

**Title:** No market-existence check in view functions

**Contract:** EventlyMarkets.sol

**Description:** `getMarketInfo`, `getPrice`, `getQuantities`, etc. accept any `_marketId`. Non-existent markets return zero / default struct values without reverting, potentially confusing off-chain consumers.

**Impact:** No on-chain fund risk. Minor UI/UX confusion.

**Recommended Fix:**

```solidity
require(_markets[_marketId].createdAt != 0, "Market does not exist");
```

**Status:** Open

***

### I-01 — Info

**Title:** NatSpec still references CPMM in key documentation strings

**Contract:** EventlyMarkets.sol

**Description:** The top-level `@notice` and the `BUYING` description in the contract header still reference "CPMM pricing (binary: pool\_j / (pool\_i + pool\_j))". The implementation is pure LMSR — these comments are outdated.

**Recommended Fix:** Update all inline documentation to reference LMSR.

**Status:** Open

***

### I-02 — Info

**Title:** No expiry or sweep for unclaimed creator fees / resolver pool

**Contract:** EventlyMarkets.sol

**Description:** `creatorAccruedFees` and `resolverPoolBalance` have no timeout mechanism. Dust can accumulate indefinitely.

**Recommended Fix:** Optional admin sweep function after a configurable timeout (e.g. 2 years) with event emission.

**Status:** Open

***

### I-03 — Info

**Title:** `whitelistedCount` is incremented but never read on-chain

**Contract:** EventlyMarkets.sol

**Description:** `whitelistedCount` is a purely informational counter. It is incremented in `addToWhitelist` and `batchWhitelist` but never read by any on-chain logic.

**Status:** Acknowledged

## Summary

| Severity  | Count |
| --------- | ----- |
| Critical  | 0     |
| High      | 0     |

| **Total** | **4** |

**Overall Assessment:** The contract demonstrates strong security hygiene with proper CEI patterns, SafeERC20 usage, and correct LMSR implementation. Known fixes (F-02, A-03) are properly applied. No production blockers identified.

***

## Round 1 — Systematic Vulnerability Scan

### Reentrancy Protection

✅ **CEI Pattern:** All external-facing functions with state changes follow Checks-Effects-Interactions. State updates precede `safeTransfer`/`_safeTransferFrom` calls.

✅ **nonReentrant Modifier:** Applied to all functions with external calls: `buyShares`, `sellToAMM`, `createSellOrder`, `cancelSellOrder`, `disputeMarket`, `settleDispute`, `claimCreatorFees`, `redeemWinnings`, `claimCancelRefund`.

✅ **LOW-001 \[RESOLVED — L-01]:** `nonReentrant` has been added to `resolveMarket`, `cancelMarket`, and `slashMarket`. While CEI is followed (state changes before external calls), adding the modifier provides defense-in-depth against future refactoring risks.

```solidity
// Current: resolveMarket lacks nonReentrant
function resolveMarket(uint256 _marketId, uint256 _winningOption) external {
    // ... state changes ...
    _cancelAllOrders(_marketId); // External transfers via _safeTransferFrom
}

// Recommended:
function resolveMarket(uint256 _marketId, uint256 _winningOption) external nonReentrant {
    // ...
}
```

**Recommended Fix:** Add `nonReentrant` to `resolveMarket`, `finalizeMarket`, `cancelMarket`, and `slashMarket`.

### Access Control

✅ Clear separation between `onlyAdmin`, `onlyWhitelisted`, and creator-only functions. No privilege escalation vectors.

✅ Creator collateral logic correctly uses `creatorCollateralReturned` flag to prevent double-claims.

✅ Invite code system properly prevents reuse via `inviteCodeUsed` mapping.

### Integer Arithmetic & Fee Precision

✅ Solidity ^0.8.20 provides automatic overflow revert.

✅ Fee rounding dust absorbed by `resolverCut`:

```solidity
uint256 resolverCut = totalFee - creatorCut - treasuryCut; // Absorbs rounding error
```

✅ `setFees` validates `totalBps <= MAX_TOTAL_FEE_BPS (500)`.

### Token Handling

✅ All USDm transfers use `safeTransfer`/`safeTransferFrom`.

✅ Proper use of `_mint`, `_burn`, `_safeTransferFrom` with correct token ID encoding (`marketId * MAX_OPTIONS + optionIndex`).

✅ P2P sell orders properly escrow shares to contract before listing.

### LMSR Mathematical Correctness

✅ `_lmsrCost` correctly implements `C(q) = b * ln(Σ exp(qᵢ/b))` with proper fixed-point conversion via PRBMath.

✅ `quoteBuy` uses tolerance `1e15` (0.001 shares) with proper bracketing and capacity validation.

✅ `getPrice` maintains `Σ Pᵢ = 1e18` (100%) via normalized exponentials.

⚠️ **INFO-001:** Upper bound `maxQ = 26,000e18` yields `q/b ≈ 130`, approaching the PRBMath `exp()` overflow threshold (\~133). Currently safe, but future library changes or parameter adjustments could trigger overflow.

**Recommended Mitigation:** Add explicit check: `require(q[i] * 1e18 / b_ < 133e18, "LMSR overflow risk")`.

***

## Round 2 — Economic Attack Analysis

### LMSR Solvency Guarantee

✅ **Invariant Verified:** `poolBalance + subsidyDeposited ≥ total winning shares × 1e18`

The LMSR mechanism ensures solvency because:

1. Initial subsidy = `b * ln(n)` covers worst-case uniform→concentrated transition
2. Trader payments (net of fees) increase `poolBalance` proportionally to shares minted
3. Fees are deducted *before* LMSR cost calculation, so shares minted correspond to net collateral
4. Redemption logic draws from `poolBalance` first, then `subsidyDeposited`, with explicit exhaustion check

### Fee Accounting Integrity

✅ Default 2.5% split (1% creator, 1% treasury, 0.5% resolver) is correctly enforced.

✅ Creator fees accrue in `creatorAccruedFees[_marketId]` and are only claimable post-finalization with `creatorFeePaid` guard.

✅ Admin market creator fees correctly redirected to treasury when `isAdminMarket || creator == address(0)`.

### Order Book Security

✅ `MAX_ORDERS_PER_BOOK = 200` (A-03 fix) prevents order book flooding.

✅ P2P orders filled before AMM; P2P trades don't affect LMSR quantities, preventing price oracle manipulation.

✅ Cheapest-first sorting with proper slippage protection via `_minShares`/`_minUsdm`.

⚠️ **INFO-002:** Binary search tolerance `1e15` in `quoteBuy` may cause rounding at the `MIN_TRADE` boundary. A trade of exactly `MIN_TRADE` could yield 0 or `2e15` shares due to tolerance bounds.

**Impact:** Negligible for practical trade sizes; protected by `require(ammShares >= MIN_TRADE)`.

### Resolution MEV Analysis

✅ `resolveMarket` requires `block.timestamp >= bettingDeadline`, preventing pre-deadline resolution. Status changes to `Resolved` before order cancellation, blocking further trades.

✅ 24-hour `DISPUTE_WINDOW` with collateral requirement prevents spam disputes.

### Subsidy Exhaustion Attack

✅ `redeemWinnings` checks `fromSubsidy <= m.subsidyDeposited` before drawing from subsidy. LMSR solvency guarantee ensures this holds under normal operation.

### claimCancelRefund Sequential Call Safety

✅ F-02 fix snapshots `optionSupply` before burning, ensuring fair pro-rata distribution across sequential claimants.

***

## Round 3 — Adversarial Triage

### Fund Theft Vectors

No theft vectors found. Funds only exit via: `redeemWinnings` (requires burning winning shares), `claimCancelRefund` (requires burning shares in cancelled market), `sellToAMM` (requires burning shares with AMM pricing), or authorized fee withdrawals.

### Permanent Bricking Vectors

No permanent bricking path found. Admin key compromise allows fee changes and treasury withdrawals, but cannot freeze user redemptions. `claimCancelRefund` remains callable regardless of admin status.

**Centralization Risk:** Admin key compromise enables fee increases to 5% cap, resolver pool redirection, market slashing, and treasury withdrawal. Recommended mitigation: deploy admin behind multisig or timelock.

### Edge Cases

✅ Zero-volume market: subsidy covers theoretical payouts; no actual shares to redeem.

✅ Single bettor monopoly: LMSR cost escalation and `maxQ` cap prevent infinite share acquisition.

✅ All bets on losing side: unclaimed `poolBalance` remains in contract (design choice, not vulnerability). No sweep mechanism.

⚠️ **INFO-003:** `closeBetting` function lacks event emission, reducing off-chain observability of market state transitions.

**Recommended Fix:** Add `emit BettingClosed(_marketId);`.

## Production Blockers

✅ **No Critical/High findings blocking deployment.** The contract is suitable for production with the following recommendations:

1. Add `nonReentrant` to resolution functions (LOW-001) as defense-in-depth
2. Deploy admin behind multisig/timelock to mitigate centralization risk
3. Monitor LMSR parameter adjustments to maintain `q/b < 133` safety margin

| **Total** | **7** |

***

## Round 1 — Systematic Vulnerability Scan

### M-01 — Reentrancy risk in resolution / cancellation functions

**Severity:** Medium **Location:** `resolveMarket()`, `cancelMarket()`, `slashMarket()`

```solidity
function resolveMarket(uint256 _marketId, uint256 _winningOption) external {
    // ...
    _cancelAllOrders(_marketId); // calls _safeTransferFrom to sellers
}
```

Functions that change market state and then perform external transfers (ERC-1155 `safeTransferFrom`) are **not** protected by the `nonReentrant` modifier. Although state is updated before transfers, an attacker could re-enter through a malicious ERC-1155 receiver and execute operations that rely on the newly set `MarketStatus`. While most state-dependent functions check for `Active` or `BettingClosed` and would revert, the possibility of unexpected interactions remains — for example, a re-entrant call to `claimCancelRefund` after status is set to `Cancelled` but before all transfers have completed.

**Recommendation:** Add `nonReentrant` to `resolveMarket`, `cancelMarket`, and `slashMarket`.

***

### M-02 — Dead order entries can permanently block new orders

**Severity:** High (categorized as M-02 but functionally High impact) **Location:** `createSellOrder()`, `cancelSellOrder()`, `_cleanOrders()`

```solidity
function cancelSellOrder(uint256 _orderId) external nonReentrant {
    // ...
    o.active = false; // marks as dead, but orderId remains in _orderBook array
    o.sharesRemaining = 0;
    _safeTransferFrom(...);
}
```

When a sell order is cancelled, it is only marked `active = false`. The order ID is **not removed** from the `_orderBook` array for its (market, option) pair — the array length remains unchanged. An attacker can fill the array with 200 orders, cancel them all, and leave the array full of dead entries. After that, **no new orders can be created** for that (market, option) pair because `oids.length < MAX_ORDERS_PER_BOOK` will always fail. This permanently disables P2P trading for that option.

**Recommendation:**

* Call `_cleanOrders(marketId, optionIndex)` inside `cancelSellOrder` after marking the order inactive.
* Alternatively, allow creating a new order even if the array is at cap, provided enough dead entries exist (compact on-the-fly).

***

### M-03 — Precision loss in LMSR pricing may cause insolvency in edge cases

**Severity:** Medium **Location:** `getPrice()`, `_lmsrCost()`, `quoteBuy()`, `redeemWinnings()`

```solidity
// Inside _lmsrCost:
sum = add(sum, exp(wrap(int256(q[i] * 1e18 / b_))));
```

The contract uses integer division inside `wrap` before exponentiation, truncating small values to zero. The binary search in `quoteBuy` has a tolerance of `1e15` shares. Over many trades, accumulated rounding errors could cause the actual pool balance (`poolBalance + subsidyDeposited`) to be slightly less than the theoretical cost function value. In the worst case, `redeemWinnings` might revert because the remaining subsidy is insufficient for the last claimant, locking their winning shares permanently.

**Recommendation:**

* Add a small safety margin when checking `fromSubsidy <= m.subsidyDeposited` and emit a warning if the margin is approaching exhaustion.
* Alternatively, use a slight over-allocation at creation (subsidy += epsilon).

***

### L-01 — Inefficient order insertion gas pattern

**Severity:** Low **Location:** `createSellOrder()`

```solidity
oids.push(0);
for (uint256 i = oids.length - 1; i > insertAt; i--) {
    oids[i] = oids[i - 1];
}
oids[insertAt] = orderId;
```

The insertion logic first pushes a dummy zero, then shifts elements rightward. With `MAX_ORDERS_PER_BOOK = 200`, the worst-case overhead is 200 SSTORE operations per insertion. Acceptable at current scale but suboptimal.

**Recommendation:** Consider using a sorted linked list or a packed structure that avoids element shifting.

***

### I-01 — `MAX_ORDERS_PER_BOOK` cap not enforced against dead entries

**Severity:** Info **Location:** `createSellOrder()`

The cap `MAX_ORDERS_PER_BOOK = 200` is enforced at creation time against the raw array length, not the count of active orders. Dead (cancelled) entries count toward the cap. This is a documentation / design gap that compounds with M-02.

**Recommendation:** Document that the cap applies to total order slots (active + dead) for a given pair, and that operators should be aware of the cleanup requirement.

***

## Round 2 — Economic Attack Analysis

### E-01 — Griefing attack via order book spam (dead entries)

**Severity:** High (see M-02 above)

An attacker fills the order book with the maximum number of orders, then cancels them all. This costs only gas (shares are returned on cancellation), with no USDm at risk. It effectively disables P2P trading for that market-option pair, forcing all trades through the AMM at potentially worse prices. On MegaETH with low gas costs, the attack is cheaper than on L1.

**Recommendation:** Same as M-02 — clean dead entries on cancellation.

***

### E-02 — Creator can claim fees on cancelled markets

**Severity:** Low **Location:** `claimCreatorFees()`, `cancelMarket()`

If a market is cancelled after the betting deadline but before resolution, the creator can still call `claimCreatorFees` (if status is `Finalized`). A creator could intentionally generate volume via wash trading, then cancel the market to extract fees, with the fee cost borne by traders. The creator's collateral is returned on honest cancellation, reducing their net risk.

**Recommendation:** Consider forfeiting accrued creator fees to treasury on market cancellation, or require a minimum active duration before fees can be claimed.

***

### E-03 — LMSR rounding edge case (see M-03)

The same precision concern from M-03 applies in the economic context: rounding errors accumulating across many binary-search iterations could cause a final redeemer to encounter an underflow in `subsidyDeposited`. See M-03 for the full analysis.

***

## Round 3 — Adversarial Triage

### A-01 — Can funds be stolen?

**Finding:** No direct theft vector found. All USDm transfers use `safeTransfer` and follow the CEI pattern under `nonReentrant`. Market pool balances are only decreased by `redeemWinnings`, `claimCancelRefund`, and `sellToAMM`. The only risk is the rounding-induced insolvency (M-03), which would block a redemption but not steal funds — they would remain locked in the contract.

### A-02 — Can the contract be permanently bricked?

**Finding:** Partial bricking possible. The CLOB order book dead-entry flooding vector (M-02) has been resolved -- \_cleanBook() is now called immediately on cancelOrder (F-DS-M02). No function permanently disables the entire contract. The admin can still withdraw treasury, create markets, and resolve disputes.

### A-03 — Edge case: single bettor takes all

If a single user buys all shares of the winning option, they receive the entire pool on redemption. Correct and expected: `redeemWinnings` uses `poolBalance + subsidyDeposited`, which is guaranteed ≥ total winning shares by LMSR theory.

### A-04 — Edge case: all bettors on losing side

If no shares of the winning option were purchased, the winning supply is zero — no one can redeem. The `poolBalance` and `subsidyDeposited` remain locked in the contract indefinitely. No sweep mechanism exists. This is a known design limitation of prediction markets, not a security flaw, but worth documenting.

## Finding Detail

### #01 — `recordSwap()` Missing Access Control

**Severity:** Medium **Contract:** EventlyProfiles.sol

`recordSwap()` could be called by any address, allowing arbitrary inflation of swap points and volume stats without actual swap activity.

**Fix:**

```solidity
modifier onlyAuthorized() {
    require(authorizedCallers[msg.sender], "Not authorized");
    _;
}
function recordSwap(address player, uint256 volumeUsdCents) external onlyAuthorized { ... }
```

**Status:** Fixed

***

### #07 — Order Book Griefing — No MAX\_ORDERS Cap

**Severity:** Medium **Contract:** EventlyMarkets.sol

`createSellOrder` inserted into a sorted array with O(n) insertion. Without a cap, an attacker could spam thousands of tiny sell orders (MIN\_TRADE = 1e15) to make `buyShares` prohibitively expensive in gas for legitimate buyers.

**Fix:**

```solidity
uint256 public constant MAX_ORDERS_PER_BOOK = 200;
// in createSellOrder:
require(_orderBook[_marketId][_opt].length < MAX_ORDERS_PER_BOOK, "Order book full");
```

**Status:** Fixed

***

## Reentrancy Analysis

All state-mutating functions were verified for reentrancy:

* `buyShares()`: pool state updated **before** USDm transfer — CEI compliant
* `sellShares()`: shares burned before USDm transfer — CEI compliant
* `claimWinnings()`: `pendingWithdrawals[msg.sender] = 0` before transfer — CEI compliant
* `claimCancelRefund()`: pre-burn snapshot taken before any burn — CEI compliant
* Custom `_locked` mutex applied on all above functions

**Verdict: No reentrancy vulnerabilities found.**

***

## Integer Overflow

All contracts use Solidity `^0.8.20`. Overflow/underflow checks are built-in. No unsafe casting identified. LMSR math uses PRBMath SD59x18 (audited fixed-point library) for `exp` and `ln` operations.
