Web3.js is a foundational JavaScript library for interacting with Ethereum nodes via JSON-RPC — accounts, contracts, transactions, and events — used in my blockchain integrations and admin tooling.
Overview
Web3.js exposes the Ethereum JSON-RPC API in JavaScript: querying balances and blocks, sending transactions, deploying and calling contracts, and subscribing to events. It is a long-standing core library in the Web3 ecosystem.
How I Use Web3.js
I use Web3.js in Node services and admin dashboards to verify on-chain payments, monitor contract events, and automate blockchain interactions for platforms like a unified Web3 admin dashboard managing token, NFT, and staking flows.
Why Web3.js?
Web3.js is battle-tested and works well on the backend for indexing and verification tasks. Its broad coverage of the Ethereum RPC surface makes it dependable for server-side blockchain automation.
