Project Layout
/contracts: Contains solidity smart contracts./deploy: Scripts for contract deployment and interaction./test: Test files.hardhat.config.ts: Configuration settings.
How to Use
yarn hardhat compile: Compiles contracts.yarn deploy: Deploys using script/deploy/deploy.ts.yarn interact: Interacts with the deployed contract using/deploy/interact.ts.yarn test: Tests the contracts.
Note: Both yarn deploy and yarn interact are set in the package.json. You can also run your files directly, for example: yarn hardhat deploy-zksync --script deploy.ts
Environment Settings
To keep private keys safe, this project pulls in environment variables from .env files. Primarily, it fetches the wallet's private key.
Rename .env.example to .env and fill in your private key:
WALLET_PRIVATE_KEY=your_private_key_here...
Network Support
hardhat.config.ts comes with a list of networks to deploy and test contracts. Add more by adjusting the networks section in the hardhat.config.ts. To make a network the default, set the defaultNetwork to its name. You can also override the default using the --network option, like: hardhat test --network dockerizedNode.
Local Tests
Running yarn test by default runs the zkSync In-memory Node provided by the @matterlabs/hardhat-zksync-node tool.
Important: zkSync In-memory Node currently supports only the L2 node. If contracts also need L1, use another testing environment like Dockerized Node. Refer to test documentation for details.
