ethers.js es una librería JavaScript/TypeScript ligera y modular que simplifica la interacción con redes compatibles con la Ethereum Virtual Machine. Ofrece una API coherente para providers, firmas, contratos y utilidades cryptográficas, todo con tipado estricto y tamaño liviano para front‑end y back‑end.
¿Por qué ethers.js?
Ligera & modular
Solo 90 kB min+gz; importa solo los módulos necesarios.
TypeScript nativo
Tipado estricto que evita errores de compilación.
Rendimiento
Serialización optimizada y manejo eficiente de eventos.
Seguridad mejorada
Firmas off‑line, BIP‑39, EIP‑1559 incorporado.
ethers.js vs Web3.js
| Aspecto | ethers.js | Web3.js |
|---|---|---|
| Tamaño bundle | ≈ 90 kB | ≈ 250 kB |
| TypeScript | Soporte nativo | Tipos externos |
| Multicall | Built‑in | Plugin |
| API de eventos | Promises + async iterators | Callbacks |
| Migración EIP‑1559 | Sí | Parcial |
Workflow de integración en 4 pasos
Provider
Infura / Alchemy / JSON‑RPC
Signer
Wallet o PrivateKey
Contract
ABI ↔ llamada/metodo
Event stream
filter → await logs
Módulos principales
ethers.providers
Conexión a RPC, WebSocket y ENS.
ethers.Wallet
Gestión de claves, firmas & BIP‑39.
ethers.Contract
Interacción ABI segura y tipada.

Buenas prácticas
- • Reutiliza providers; evita instanciar nuevos en cada render.
- • Implementa multicall para reducir latencia y gas.
- • Maneja reconexión automática en WebSocket provider.
- • Tipa contratos con
typechain. - • Suscribe a eventos con filtros específicos, no catch‑all.
ethers.js is a lightweight, modular JavaScript/TypeScript library that simplifies interaction with Ethereum Virtual Machine-compatible networks. It provides a consistent API for providers, signing, contracts, and cryptographic utilities, all with strict typing and a small footprint suitable for front-end and back-end.
Why ethers.js?
Lightweight & modular
Only 90 kB min+gz; import only needed modules.
Native TypeScript
Strict typing prevents compilation errors.
Performance
Optimized serialization and efficient event handling.
Enhanced security
Offline signing, BIP-39, EIP-1559 built-in.

Best practices
- • Reuse providers; avoid instantiating new ones on every render.
- • Implement multicall to reduce latency and gas.
- • Handle auto-reconnect on WebSocket provider.
- • Type contracts with
typechain. - • Subscribe to events with specific filters, not catch-all.
