LZ Token Bridge

Quick demo on using OFT protocol to send tokens crosschain using LayerZero

Getting Started

Clone this repository. If you dont have foundry installed, set it up

Or, if your repo already exists, run:

forge build

Create a .env file with following secrets

PRIV_KEY
MUMBAI_RPC
GOERLI_RPC
ETHERSCAN_API_KEY
POLYGONSCAN_API_KEY

Deploying cross chain token

At the moment, the codebase scripts are configured to bridge a token from mumbai testnet to goerli testnet. This can be changed by changing chain id and lz_endpoints in deploy.s.sol

1. Run make deploy_src to deploy a sample token and proxy contract on the source chain
2. Run make deploy_dest to deploy receiver OFT contract on the destination chain
3. Run make deploy_setup to setup source chain contract to interact with destination contract
4. Run make init_send to initiate a token bridge call from source chain

Development

This project uses Foundry. See the book for instructions on how to install and use Foundry.
