Build With Proto-CCTP

ProtoCCTPGateway

Use the ProtoCCTPGateway contracts on all chains. The contracts are identical on all deployed chains.

send(uint _destChainId, address _recipient, uint _USDCamount);

send(uint _destChainId, address _recipient, uint _USDCamount, bytes memory _userData);

The send() function initiates a transfer of USDC or Bridged USDC to a recipient on a destination chain.

• _destChainId = The chain ID of the destination blockchain

• _recipient = The wallet address of the recipient on the destination blockchain

• _USDCamount = The amount of USDC or Bridged USDC to be transferred (6 decimal)

• _userData_ = OPTIONAL. Additional data to be sent along with the transfer.

How To Use

1. Use the official Circle USDC - On testnets, obtain from the official testnet faucet.

2. Approve the desired amount of USDC to the ProtoCCTPGateway contract.

3. Call send(_destChainId, _recipient, _amount)
