Modern, type-safe TypeScript interface for Ethereum
Last updated: July 2026
Viem is a modern, lightweight, TypeScript-first library for interacting with Ethereum — a low-level interface for reading blockchain data, sending transactions, interacting with contracts, and more — designed as a faster, more type-safe, better-architected alternative to Ethers.js and Web3.js. It's the foundation that Wagmi is built on, but it's also used directly in backends, scripts, and non-React frontends. Viem's appeal is developer experience: excellent TypeScript inference (types flow from your ABIs), a well-designed modular API, strong performance, small bundle size, and thoughtful abstractions that make common tasks clean while keeping low-level control available. It has rapidly become a preferred choice for new EVM projects. The trade-offs: as a relatively newer library it broke from the long-dominant Ethers.js conventions (a learning curve for developers used to Ethers), migrating existing Ethers codebases takes effort, and its low-level nature means you build more yourself than with a batteries-included framework. But for developers building anything that interacts with EVM chains in TypeScript — frontends, backends, scripts, or tooling — Viem is the modern standard-bearer, offering superior type safety, performance, and architecture, and it (with Wagmi on top) has largely become the default choice for new Ethereum development, displacing the older libraries.
