# Cross Chain Swaps

#### **Cross Chain Swaps (Different Assets)**

Cross chain swaps provides 1-2min swaps between assets on the origin and destination chains e.g. USDC Arbitrum to USDT on Ethereum. 

These intents are filled optimistically by the Everclear solver using our inventory. Fees are slightly higher than regular intents and depend on available liquidity and the route.

### 🧠 Example: **Fast Path Swap (Bridge + Swap)**

Transfer **10,000 USDC** from **Optimism (chainId 10)** → **Ethereum (chainId 1)** as **USDT**, via Fast Path.

➡️ Must include the `outputAsset` field for Swaps.

```js
const axios = require('axios');

const data = JSON.stringify({
  "amount": "10000000000", // 10,000 USDC (in decimals)
  "origin": "10", // Optimism
  "destinations": ["1"], // Ethereum
  "inputAsset": "0x0b2C639c533813f4Aa9D7837CAf62653d097Ff85", // USDC on OP
  "outputAsset": "0xdAC17F958D2ee523a2206206994597C13D831ec7", // USDT on ETH
  "to": "0xade09131C6f43fe22C2CbABb759636C43cFc181e",
  "from": "0xade09131C6f43fe22C2CbABb759636C43cFc181e",
  "callData": "",
  "isFastPath": true // Fast Path = under ~2 mins
});

const config = {
  method: 'post',
  url: 'https://api.everclear.org/intents/',
  headers: { 
    'Content-Type': 'application/json'
  },
  data
};

axios.request(config)
  .then((response) => console.log(JSON.stringify(response.data, null, 2)))
  .catch((error) => console.error(error));
```
