Environment

Now that our installation is complete, let's configure the development environment for Scaffold ETH-2 which consists of three terminals:

  1. Run a local network in the first terminal:
yarn chain

This command starts a local Ethereum network using Hardhat. The network runs on your local machine and can be used for testing and development. You can customize the network configuration in hardhat.config.ts.

  1. On a second terminal, deploy the test contract:
yarn deploy

This command deploys a test smart contract to the local network. The contract is located in packages/hardhat/contracts and can be modified to suit your needs. The yarn deploy command uses the deploy script located in packages/hardhat/deploy to deploy the contract to the network. You can also customize the deploy script.

  1. On a third terminal, start your NextJS app:
yarn start

Visit your app on: http://localhost:3000. You can interact with your smart contract using the contract component or the example ui in the frontend.

  • Tweak the app config in packages/nextjs/scaffold.config.ts
  • Run smart contract test with yarn hardhat:test
  • Edit your smart contract YourContract.sol in packages/hardhat/contracts
  • Edit your frontend in packages/nextjs/pages
  • Edit your deployment scripts in packages/hardhat/deploy
