🏗 Scaffold-ETH 2 with Hardhat + Monad Testnet Configuration

Documentation | Website

🧪 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, Hardhat, 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.

Requirements

Before you begin, you need to install the following tools:

• Node (>= v20.18.3)
• Yarn (v1 or v2+)
• Git

Quickstart

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

1. Install dependencies if it was skipped in CLI:

cd my-dapp-example
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 packages/hardhat/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 Debug Contracts page. You can tweak the app config in packages/nextjs/scaffold.config.ts.

Run smart contract test with yarn hardhat:test

• Edit your smart contracts in packages/hardhat/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/hardhat/deploy

Contract Verification

After deploying your smart contract to a testnet or mainnet, you can verify it on block explorers like Etherscan or Sourcify. This makes your contract source code publicly available and allows users to interact with it through the block explorer.

Sourcify Verification (Recommended)

Scaffold-ETH 2 is configured to use Sourcify for contract verification by default. Sourcify is a decentralized verification platform that supports multiple block explorers.

For Monad Testnet

1. Deploy your contract to Monad testnet:

yarn deploy --network monadTestnet

2. Verify your contract using the hardhat-deploy plugin:

yarn hardhat-verify --network monadTestnet <CONTRACT_ADDRESS>

Replace <CONTRACT_ADDRESS> with the address of your deployed contract.

Configuration

The Sourcify configuration is already set up in packages/hardhat/hardhat.config.ts:

sourcify: {
  enabled: true,
  apiUrl: "https://sourcify-api-monad.blockvision.org",
  browserUrl: "https://testnet.monadexplorer.com",
},
