Web3.js is a collection of TypeScript/JavaScript libraries for interacting with Ethereum and EVM-compatible blockchains via the JSON-RPC API, including smart contract interaction, ABI encoding/decoding, account management, and event subscriptions. The libraries were officially sunset on March 4th, 2025, so the project is no longer actively developed.
Use cases
- interact with ethereum smart contracts from javascript
- deploy and call smart contracts in a dapp
- encode and decode contract ABIs in typescript
- sign transactions and manage ethereum accounts
- subscribe to on-chain events over websocket
- connect to any EVM chain via JSON-RPC
- resolve ENS names in a web app
When to choose
- maintaining an existing dapp already built on web3.js
- you need the mature, well-documented oldest Ethereum JS library and accept it is sunset
- working in a legacy Node.js or browser codebase standardized on web3.js
When to avoid
- starting a new project - the libraries are officially sunset as of March 2025
- you want ongoing updates, security patches, or community support
- you prefer actively maintained alternatives like ethers.js or viem
