DappBoilerplate is a Web3 boilerplate that combines Next.js, RainbowKit, wagmi, and Chakra UI to give you a working decentralized application scaffold out of the box. It is maintained as an open-source repository on GitHub and targets developers who want to skip environment setup and start building dApps immediately.
What is DappBoilerplate?
DappBoilerplate is a decentralized application starter kit that runs on Next.js and uses React, RainbowKit, wagmi, and Chakra UI as its core stack. It takes a fresh clone of the repository, plus a wallet like MetaMask, and produces a running web app where users can connect their wallet, view their account balance, sign messages on-chain, and switch between Ethereum and Layer 2 networks. The project lives at github.com/JalelTounsi/DappBoilerplate and invites forking and contributions.
Key Features
- Fully functional Next.js app — includes a
pages/index.tsxentry point that auto-updates as you edit, with hot reload viayarn dev. - Wallet connection with RainbowKit — provides a customizable connect-wallet flow that works with MetaMask and other injected Ethereum wallets.
- Account balance display — shows the connected wallet's balance immediately after connection.
- On-chain message signing — lets users sign a message with their wallet, a common requirement for authentication flows.
- Chain switching — allows users to switch between Ethereum and Layer 2 networks directly from the UI.
- Chakra UI styling — a pre-configured component library for building responsive interfaces without custom CSS.
- Vercel deployment ready — the README points to Next.js deployment documentation, making it easy to publish the app.
Who is it for?
- Web3 developers who want to avoid wiring together wallets, chain providers, and UI frameworks from scratch.
- Hackathon teams that need a rapid starting point for a dApp prototype, including wallet interactions.
- Learners exploring how RainbowKit, wagmi, and Next.js work together in a real project.
What can you do with it?
- Prototype an Ethereum dApp — connect a wallet, view balances, and sign messages with minimal code.
- Experiment with Layer 2 networks — switch between chains to test how your app behaves on different networks.
- Build a production foundation — extend the boilerplate with smart contract calls, data fetching, and custom business logic.
How does it work?
The onboarding flow is described in the README: clone the repository, run yarn install to install dependencies, then yarn dev to start the development server at http://localhost:3000. The main page is pages/index.tsx, and edits to that file hot-reload in the browser.
FAQ
Is DappBoilerplate free to use?
Yes, the project is open source and the README explicitly says "Feel free to fork and contribute." It is available on GitHub without any licensing restrictions mentioned.
How do I install DappBoilerplate?
Run git clone https://github.com/JalelTounsi/DappBoilerplate.git, then cd DappBoilerplate, install dependencies with yarn install, and start with yarn dev.
What chains does it support?
The feature list states that users can switch between Ethereum and Layer 2s, so it supports Ethereum and Layer 2 networks out of the box.
Can I deploy it to Vercel?
Yes, the README includes a "Deploy on Vercel" section that links to the Vercel platform and Next.js deployment documentation.
