npm install
npx hardhat test
Many of the example contracts make use of LayerZeroEndpointMock.sol which is a nice way to test LayerZero locally!
configure an .env file to have the values of .env.example and test deploy! (Use a real LayerZero endpoint in place of 0x0000..)
npx hardhat --network mumbai deploy --endpoint 0x0000000000000000000000000000000000000000
