# Cancel/Refund

If the Swap can't be completed, you can always refund.

The original funds can be reclaimed by the user if they no longer want to complete the swap (took too long, lost the secret, swap failed, etc.)

### Example

```javascript

const SWAP_CONTRACT_ADDRESS_ON_SOURCE_CHAIN = "0x..."; // get this from the docs for your network
const ABI = '{
    "constant": false,
    "inputs": [
      {
        "internalType": "bytes32",
        "name": "_contractId",
        "type": "bytes32"
      }
    ],
    "name": "refund",
    "outputs": [
      {
        "internalType": "bool",
        "name": "",
        "type": "bool"
      }
    ],
    "payable": false,
    "stateMutability": "nonpayable",
    "type": "function"
  }';

const provider = new ethers.providers.Web3Provider(window.ethereum);
const signer = provider.getSigner();

const safeSwap = new ethers.Contract(SWAP_CONTRACT_ADDRESS_ON_SOURCE_CHAIN, ABI, signer);

const response = await safeSwap.refund(swapInfo.sourceContractId, { gasLimit: 200000 });
return response.hash;
