Ethers.js is a complete, compact Ethereum library and wallet implementation written in TypeScript. It provides wallet management, contract interaction via ABIs, JSON-RPC provider connections, and first-class ENS name support.

Use cases

• interact with ethereum smart contracts from javascript
• create and manage ethereum wallets in the browser
• send transactions and read blockchain data via json-rpc
• import and export json wallets and bip39 mnemonic phrases
• resolve ens names in a web3 app
• connect to infura, alchemy, or metamask providers
• build a dapp frontend with typescript

When to choose

• you need a well-documented, tree-shakeable TypeScript library for Ethereum
• you want client-side key management without sending private keys to a server
• you need broad provider support (Infura, Alchemy, MetaMask, Etherscan) in one library
• you want human-readable ABI contract bindings

When to avoid

• you are targeting non-EVM blockchains like Solana or Bitcoin
• you need a full node or indexing service rather than a client library
• your project is Python, Go, or another non-JavaScript stack
