Laika

Laika is a request builder for web3 - like Postman for blockchains. It allows you to interact with smart contracts without writing code, supporting all EVM-compatible blockchains with universal UI for ABIs.

• Request Management: Send and sign transactions using multiple wallets via RainbowKit
• Collections & Organization: Hierarchical project organization (Collections → Folders → Smart Contracts)
• Environment Variables: Global and local environment variables with {{variable}} syntax for dynamic values
• Code Generation: Generate JavaScript code snippets (web3.js, ethers.js) from contract interactions
• Integrated Documentation: Built-in ABI documentation viewer with Monaco Editor
• Multi-tab Workspace: Manage multiple contract requests simultaneously

• React 19 + TypeScript + Vite
• TanStack Router (file-based routing)
• Zustand (state management with persistence)
• Tailwind CSS v4 + shadcn/ui components
• wagmi + viem + RainbowKit (Web3 integration)
• Monaco Editor (code/ABI display)
