Quickstart

To get started with Scaffold-ETH 2, follow the steps below:

1. Clone this repo & install dependencies

git clone https://github.com/scaffold-eth/scaffold-eth-2.git
cd scaffold-eth-2
yarn install

2. 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.

3. 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.

4. 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. You can 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
