MetaMask Wallet | Your Gateway to the Decentralized Web

MetaMask is a leading crypto wallet and gateway to blockchain apps, enabling millions of users to explore decentralized finance (DeFi), NFTs, and Web3 in a secure, user-friendly manner. Available as both a browser extension and mobile app, MetaMask simplifies the way users interact with Ethereum-based dApps, trade tokens, store crypto securely, and manage digital identities.

What is MetaMask?

MetaMask is a non-custodial cryptocurrency wallet developed by ConsenSys, one of the most prominent blockchain software companies in the world. It allows users to manage Ethereum (ETH) and other ERC-20 tokens, access DeFi protocols, and interact with smart contracts—all without relying on centralized intermediaries.

Designed for accessibility, privacy, and control, MetaMask operates directly in your web browser (Chrome, Firefox, Brave, Edge) or via the mobile app (iOS/Android). Whether you are a beginner or an advanced blockchain user, MetaMask empowers you to securely participate in the decentralized web.
