Sample scripts for using Circle's CCTP to cross-chain transfer USDC.

Simple Cross-Chain Transfer of USDC using CCTP

This script sets up a cross-chain transfer with the following specs:

1. Source chain: Ethereum Sepolia
2. Destination chain: Arbitrum Sepolia

This script uses ethers.js (v5.7).

CCTP contract addresses for mainnet and testnet can be found here.

Quick Setup

1. Clone this repo (star it if you like it!)
2. Create a .env file in the root of the project
3. Use the .env.example to populate your .env file
4. For TRANSFER_AMOUNT, fill in 10000000 in order to transfer 10 USDC
5. Remember to fund your wallets with ETH on both the source AND destination chain for this script to work!
6. Once everything is set up, run node index and your cross-chain transfer will begin! 🏄‍♂️
