# 3.1 EVM Compatible Chains

The following table lists the contract addresses and corresponding domain values for supported EVM-compatible chains:

| **Chain Name** | **Contract Address**                       | **domainValue** |
| -------------- | ------------------------------------------ | --------------- |
| Ethereum       | 0xeC0D8Cfd081ccce2D6Ed4E3dd8f248D3cAa3d24B | 0               |
| Avalanche      | 0x0D4d2595B1d83AB6110b4291816D62d1417C5A8B | 1               |

The usage method of WanBridge's CCTP is as follows:

1. Call the contract interface `estimateFee` on the From chain to get the cross-chain fee (native coin). Provide the `domainValue` of the To chain as input.
2. Call the contract interface `depositForBurn` function on the From chain to initiate the USDC cross-chain transfer, pass the native coin fee as `payableAmount`, the cross-chain amount as `amount`, the domain value as `destinationDomain`, the receiving address on the To chain as `mintRecipient`, and the USDC token address on the From chain as `burnToken`.
3. The WanBridge backend will monitor events and help users complete the **claim** operation on the To chain.
