How It Works
Under the hood, HookSmith is a bridge between raw Ethereum smart contract data and modern frontend development.
1. ABI Parsing
When you paste your JSON ABI, HookSmith's parser analyzes every function and event. It identifies:
- Read Functions: View functions that don't require gas (`view`, `pure`).
- Write Functions: State-changing functions (`payable`, `nonpayable`).
- Events: Contract events that can be listened to.
- Input/Output Types: Precision mapping of Solidity types to TypeScript types (e.g., `uint256` → `bigint`).
2. Hook Generation
Using the parsed schema, the engine constructs a custom React hook (e.g., `useMyContract`).
- It wraps Wagmi v2 hooks (`useReadContract`, `useWriteContract`).
- It generates strictly typed interfaces for all arguments.
- It handles common patterns like loading states and error handling automatically.
3. Project Scaffolding
If you choose to download the Starter Project, HookSmith generates a complete Next.js application on the fly.
- Dynamic Zip Generation: The backend creates a zip file in-memory containing your specific hook and configured Wagmi providers.
- Design System: It includes a pre-configured Tailwind CSS setup with the "Bento" UI system.
- Wallet Connection: RainbowKit or similar connectors are pre-installed and configured.
