## What it is
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

## Facets
- artifact type: library
- maturity: stable
- function: sdk, http-client, cryptography, auth
