Introduction to MetaMask Chrome Extension

MetaMask Chrome Extension is a browser-based cryptocurrency wallet that allows users to interact securely with decentralized applications (dApps) on Ethereum and other compatible blockchains. It combines secure account management, transaction signing, and portfolio tracking directly in the Chrome browser.

Unlike web wallets that store private keys online, MetaMask keeps keys encrypted in the browser extension, providing user control over digital assets while interacting with the Web3 ecosystem.

This guide covers installation, account setup, security tips, dApp interaction, and best practices for using MetaMask Chrome Extension safely.
