Details

This repo demonstrates how to send USDC cross-chain (with additional instructions to be used by a contract) by using Wormhole's generic-messaging layer and by interacting with Circle's Cross-Chain Transfer Protocol.

Compiling contracts

Install Foundry tools, which includes forge, anvil and cast CLI tools.

cd evm
make build
