The trusted Web3 wallet extension that empowers millions to securely access decentralized applications, manage crypto assets, and explore the blockchain ecosystem with confidence.
The MetaMask Extension is one of the most widely used cryptocurrency wallet solutions in the world. Designed as a browser extension, MetaMask acts as a secure bridge between traditional web browsers and decentralized blockchain networks. It allows users to store digital assets, interact with decentralized applications (dApps), and manage blockchain identities—all from one intuitive interface.
Originally launched to support Ethereum, MetaMask has evolved into a powerful multi-chain wallet supporting Ethereum-compatible networks such as Binance Smart Chain, Polygon, Avalanche, and many more. With millions of active users worldwide, MetaMask has become a cornerstone of the Web3 ecosystem.
MetaMask Extension functions as your gateway to Web3. It enables seamless interaction with decentralized finance platforms, NFT marketplaces, DAO governance tools, and blockchain-based games. Without MetaMask, accessing most decentralized applications would be nearly impossible for everyday users.
MetaMask is a non-custodial wallet, meaning users retain full control over their private keys and funds. Unlike centralized exchanges, MetaMask does not store or manage your assets. Everything is controlled locally by the user, enhancing security and independence.
🔐 Important Security Tip: Always download MetaMask only from the official website or verified browser extension stores. Never share your recovery phrase with anyone.
MetaMask operates as a browser-based wallet that injects a Web3 provider into supported browsers. When a user visits a decentralized application, the dApp can request access to MetaMask. The user must approve every interaction, ensuring full transparency and control.
MetaMask Extension is compatible with all major desktop browsers, making it accessible to users across different operating systems and environments.
