# 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
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.evently.market/product/swap-and-bridge.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
