Run Tests

npx hardhat test

How to run the PingPong example

1. Deploy both PingPong contracts:

npx hardhat --network bscTestnet deploy --tags PingPong
npx hardhat --network avalancheFujiTestnet deploy --tags PingPong

2. Verify both contracts:

npx hardhat verify --network bscTestnet [Address of the contract] [Address of the LayerZero endpoint on BSC Testnet]
npx hardhat verify --network avalancheFujiTestnet [Address of the contract] [Address of the LayerZero endpoint on Fuji]

3. Set the remote addresses, so each contract can receive messages:

npx hardhat --network bscTestnet setTrustedRemote --target-network avalancheFujiTestnet --contract PingPong
npx hardhat --network avalancheFujiTestnet setTrustedRemote --target-network bscTestnet --contract PingPong

4. Send a cross chain message from bscTestnet to avalancheFujiTestnet !

npx hardhat --network bscTestnet ping --target-network avalancheFujiTestnet
