solidity-examples v0.0.2-beta.83

Simple LayerZero omni chain contracts

Setup the project

npm install

Run tests

npx hardhat test

NOTE: You must add a .env with a MNEMONIC that is funded on testnets !

configure an .env file to have the values of .env.example and test deploy! (Use a real LayerZero endpoint in place of 0x0000..)

Testing Cross Chain Messages

1. Deploy both OmniCounters:

npx hardhat --network fantom-testnet deploy
npx hardhat --network mumbai deploy 

2. Send a cross chain message from mumbai to fantom-testnet !

npx hardhat --network mumbai omniCounterIncrement --target-network fantom-testnet

3. Optionally use this command in a separate terminal to watch the counter increment in real-time.

npx hardhat --network fantom-testnet omniCounterPoll    

For further reading, and a list of endpoint ids and deployed LayerZero contract addresses please take a look at the Gitbook here: https://layerzero.gitbook.io/

Read the currently set Oracle

npx hardhat --network mumbai omniCounterGetOracle

Set a custom Oracle for the deployed OmniCounter

npx hardhat --network mumbai omniCounterSetOracle --target-network mumbai --oracle 0xORACLE_ADDR

See some examples in /contracts 🙌

Many of the example contracts make use of LayerZeroEndpointMock.sol which is a nice way to test LayerZero locally!
