Viem is a TypeScript library providing low-level, stateless primitives for interacting with Ethereum, serving as a modern alternative to ethers.js and web3.js. It offers modular, tree-shakable modules with end-to-end type safety inferred from contract ABIs and EIP-712 typed data.

Use cases

• interact with ethereum smart contracts from typescript
• read blockchain data like block numbers and balances
• encode and decode contract ABIs
• build a dapp frontend that talks to ethereum
• sign and send ethereum transactions
• work with EIP-712 typed data
• connect browser extension or WalletConnect wallets
• test contracts against forked ethereum networks

When to choose

• you want a lightweight, tree-shakable ethereum library with strong TypeScript inference
• you are building dapps or libraries on top of wagmi
• you need stable, well-tested JSON-RPC abstractions with small bundle size
• you prefer modular, composable APIs over monolithic web3 libraries

When to avoid

• you need a non-EVM blockchain SDK
• your project requires JavaScript-only support without TypeScript 5+
• you depend on plugins or tooling built specifically for ethers.js or web3.js
