base on An Omnichain Interoperability Protocol # LayerZero - an Omnichain Interoperability Protocol This repository contains the smart contracts for LayerZero Endpoints. For developers looking to build on top of LayerZero please refer to the [docs](https://layerzero.gitbook.io/docs/) ## Overview LayerZero is an Omnichain Interoperability Protocol designed for lightweight message passing across chains. LayerZero provides authentic and guaranteed message delivery with configurable trustlessness. The protocol is implemented as a set of gas-efficient, non-upgradable smart contracts. ## Development ### Interfaces add this to your package.json ` "@layerzerolabs/contracts": "latest", ` ### Setup - copy .env.example to .env and fill in variables - `yarn install` ### Testing `yarn test` #### Single Test File `yarn test test/Endpoint.test.js` ### Gas Uasge `yarn test:gas` ### Coverage `yarn test:coverage` ### Lint `yarn lint` only lints .js/.ts files ## Deployment Deploy networks are generated based on tags. #### Hardhat `yarn dev` spins up local environment and deploys contracts #### Development ``` hardhat --network rinkeby-testnet deploy hardhat --network rinkeby-sandbox deploy ``` #### Production ``` hardhat --network ethereum deploy ``` ### Adding a new network 1. Update [hardhat config](hardhat.config.ts) with network 1. refer to [STAGING_MAP](utils/deploy.js) for staging environments supported 2. Update [endpoints.json](constants/endpoints.json) with network 3. Make sure that key in endpoints.json matches network name in hardhat Example: One LayerZero Network ``` //hardhat.config.ts ethereum: { url: `{rpc address}`, chainId: 1, //chainlist id } //endpoints.json "production": { ... "ethereum": { "id": 1 //layerzero chain id } } ``` Example: More than one LayerZero Network on same chain (using expandNetwork) ``` //hardhat.config.ts ...expandNetwork({ ropsten: { url: `{rpc address}`, chainId: 3, //chainlist id } }, ["testnet", "sandbox"]), //endpoints.json "development": { ... "ropsten": { "id": 4 //layerzero chain id } } ``` ### Acknowledgments Thank you to the core development team for building the LayerZero Endpoints: Ryan Zarick, Isaac Zhang, Caleb Banister, Carmen Cheng and T.
