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.
