Now that our installation is complete, let's configure the development environment for Scaffold ETH-2.

1. Initialize a Local Blockchain:

In the first terminal, run a local network:

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.

2. Deploy Your Smart Contract:

In the 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.

3. Launch your NextJS Application:

In the 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.

What's Next:

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