We are excited to launch Contracts UI Builder, a tool that helps you to spin up a quick React frontend for deployed smart contracts. This development wizard instantly generates complete dapp interfaces with wallet integration and multi-network support, eliminating the need to build contract interaction UIs from scratch.
The OpenZeppelin Contracts UI Builder is a smart contract frontend generator that transforms any deployed contract into a simple, functional React application. By analyzing your contract's ABI, it automatically creates user-friendly interfaces for all contract functions, complete with wallet integration and cross-chain compatibility.
Building blockchain apps frontends traditionally requires extensive knowledge of wallet integration, blockchain libraries, and React development. Contracts UI Builder removes these barriers by auto-generating production-ready interfaces.
Perfect for rapid prototyping, MVP development, and contract testing. Generate functional interfaces in a few clicks rather than spending days on frontend development.
Each generated interface includes:
Generate testing interfaces for deployed contracts on testnets. QA teams can interact with all contract functions without requiring custom tooling or technical blockchain knowledge.
Create professional-looking dapp interfaces for stakeholder demos, investor presentations, or user testing sessions. Show contract functionality without exposing technical complexity.
Launch minimum viable products quickly by using generated frontends as starting points. Deploy immediately or extend with custom features as your project grows.
Create simple interfaces for team members to interact with deployed contracts. Perfect for non-technical stakeholders who need contract access.
Navigate to builder.openzeppelin.com, select your network, and input your contract address. The tool automatically fetches your contract's ABI and displays all available functions.
Choose which write function to execute on in your dapp interface. Customize function names, add descriptions, and configure input validation as needed.
Then simply generate your complete React application. Preview the interface, test functionality, and export the full codebase for deployment or further development.
Watch our hands-on demonstration of Contracts UI Builder in action. This 4-minute tutorial walks you through the complete process, from contract input to frontend export, showing exactly how fast and simple it is to create frontend interfaces for deployed smart contracts with the OpenZeppelin Contracts UI Builder.
At the moment, the Contracts UI Builder supports all major EVM-compatible networks:
Selected non-EVM networks will also be integrated, with integration currently in development for Solana, Stellar, and Midnight.
The tool automatically detects network requirements and configures the frontend accordingly.
Contracts UI Builder works with any deployed smart contract. This includes ERC-20 tokens, ERC-721 NFTs, DeFi protocols, DAOs, gaming contracts, and custom business logic contracts.
No React experience is required to use the generated interface. However, if you want to modify or extend the code, basic React knowledge can be helpful. The exported code follows standard React patterns and includes clear documentation.
Yes, the generated React components use standard CSS classes and can be styled with any CSS framework or custom styles. The code is fully exportable and modifiable.
Yes, all generated code follows React best practices and includes proper error handling, loading states, and security considerations. You can deploy the generated interface directly to production.
Generated interfaces include wallet connection functionality using popular Web3 libraries, such as viem, wagmi, and RainbowKit. Users can connect MetaMask, WalletConnect-compatible wallets, and other major wallet providers.
Absolutely. The generated components are modular and can be imported into existing React applications. Each contract function becomes a standalone React component.
Yes, Contracts UI Builder supports integration with OpenZeppelin Relayer for gasless transaction execution. This allows users to interact with your smart contracts without needing gas, which significantly improves the user experience.
