Web3.js Interaction

Web3.js is a JavaScript library that enables communication with Ethereum and EVM-compatible blockchains. It abstracts blockchain protocol details and provides high-level APIs for sending transactions, calling smart contracts, managing accounts, and listening to blockchain events. Web3.js connects to Ethereum nodes (via Infura, Alchemy, or self-hosted) and enables decentralized applications (dApps) to interact with the blockchain. Core capabilities: account management, transaction sending, smart contract interaction, event listening, and utility functions for cryptography and encoding.
