🧪 An open-source, up-to-date toolkit for building decentralized applications (dapps) on the Ethereum blockchain. It's designed to make it easier for developers to create and deploy smart contracts and build user interfaces that interact with those contracts.
⚙️ Built using NextJS, RainbowKit, Foundry, Wagmi, Viem, and Typescript.
- ✅ Contract Hot Reload: Your frontend auto-adapts to your smart contract as you edit it.
- 🪝 Custom hooks: Collection of React hooks wrapper around wagmi to simplify interactions with smart contracts with typescript autocompletion.
- 🧱 Components: Collection of common web3 components to quickly build your frontend.
- 🔥 Burner Wallet & Local Faucet: Quickly test your application with a burner wallet and local faucet.
- 🔐 Integration with Wallet Providers: Connect to different wallet providers and interact with the Ethereum network.
Before you begin, you need to install the following tools:
- Node (>= v18.18)
- Yarn (v1 or v2+)
- Git
To get started with Scaffold-ETH 2, follow the steps below:
- Install dependencies if it was skipped in CLI:
cd my-dapp-example
yarn install
- Run a local network in the first terminal:
yarn chain
This command starts a local Ethereum network using Foundry. The network runs on your local machine and can be used for testing and development. You can customize the network configuration in packages/foundry/foundry.toml
.
- 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/foundry/contracts
and can be modified to suit your needs. The yarn deploy
command uses the deploy script located in packages/foundry/script
to deploy the contract to the network. You can also customize the deploy script.
- 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 Debug Contracts
page. You can tweak the app config in packages/nextjs/scaffold.config.ts
.
Run smart contract test with yarn foundry:test
- Edit your smart contracts in
packages/foundry/contracts
- Edit your frontend homepage at
packages/nextjs/app/page.tsx
. For guidance on routing and configuring pages/layouts checkout the Next.js documentation. - Edit your deployment scripts in
packages/foundry/script
