The long-dominant, complete JavaScript library for Ethereum
Last updated: July 2026
Ethers.js is one of the most widely-used JavaScript/TypeScript libraries for interacting with Ethereum, long the dominant choice for reading blockchain data, managing wallets, signing, and interacting with smart contracts before Viem emerged as a modern challenger. Known for being complete, well-documented, and relatively compact, Ethers has powered a huge portion of the EVM ecosystem's frontends, backends, and scripts, with a clean API covering providers, signers, contracts, and utilities (ABI encoding, units, ENS). Its maturity means enormous community knowledge, countless tutorials, and battle-tested reliability across years of production use. The trade-offs: while still extremely popular and fully capable, momentum in new projects has shifted toward Viem (which offers stronger TypeScript inference and a more modern architecture), some find its type safety less thorough than Viem's, and version transitions (v5 to v6) introduced changes to adapt to. But for the vast number of existing projects built on it — and developers who prefer its mature, well-documented, familiar API — Ethers.js remains a rock-solid, complete choice for EVM development, and its enormous existing footprint and documentation make it a safe, well-understood option even as newer libraries gain ground in greenfield projects.
