🏗 Scaffold-ETH 2 - Foundry Edition + Monad 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, 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.

Requirements

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

• Node (>= v18.18)
• Yarn (v1 or v2+)
• Git

Quickstart

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

1. Install dependencies:

cd se2-foundry-monad
yarn install && forge install --root packages/foundry

2. 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.

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/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.

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 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

Deploying to Monad

Smart Contracts

First, check out the existing .env file and fill in the necessary values:

MONAD_RPC_URL= 
MONAD_SOURCIFY_VERIFIER_URL=

# Do not change the name of the variable below, put Monad chain id here
FOUNDRY_CHAIN_ID=

Also, change the ETH_KEYSTORE_ACCOUNT to scaffold-eth-custom to deploy!

Then, run the following command to deploy your contract to Monad:

yarn deploy --network monad

To verify your contract, run the following command:

yarn verify --network monad

To run both deploy and verify, run the following command:

yarn deploy --network monad && yarn verify --network monad

Frontend

First, copy the .env.example file to .env.local and fill in the values.

Then, change the target network in packages/nextjs/scaffold.config.ts to monad

targetNetworks: [monad],

Then, run the following command to deploy your nextjs app to production:

yarn vercel

You should be able to see a URL to your app on Vercel.
