Laika AI

Laika is a Web3 request builder designed to simplify smart contract interactions across all Ethereum Virtual Machine (EVM) compatible blockchains. It provides a Postman-like interface tailored for blockchain developers and teams who want to interact with smart contracts without writing code. Laika supports both read and write methods on contracts, enabling users to send and sign transactions through multiple wallets integrated via RainbowKit. Its universal ABI (Application Binary Interface) UI automatically fetches and displays contract methods, making it easier to explore and test smart contracts.

The tool organizes projects hierarchically into collections, folders, and smart contracts, allowing developers to manage complex workflows efficiently. It also features multi-tab workspaces for handling multiple contract requests simultaneously. Laika generates JavaScript code snippets compatible with popular libraries like web3.js and ethers.js, helping developers transition from no-code interactions to programmatic integration. The built-in Monaco Editor enhances the experience by providing integrated ABI documentation and code display.

Laika is built with modern web technologies including React, TypeScript, and Tailwind CSS, and leverages wagmi, viem, and RainbowKit for seamless Web3 wallet integration. It is open source under the MIT License, encouraging community contributions and transparency. Developers can get started by cloning the GitHub repository, installing dependencies with Bun, and running the development server. Comprehensive documentation and a video tutorial are available to guide new users through setup and usage.

By abstracting the complexity of smart contract calls and wallet interactions, Laika accelerates development cycles and testing for DeFi projects, DAO tooling, and infrastructure teams. It stands out by combining multi-chain support, no-code contract interaction, and code generation in a single, user-friendly interface.
