The MetaMask Extension is a popular browser-based cryptocurrency wallet that enables users to securely manage digital assets and interact with decentralized applications (dApps). Serving as a gateway to the decentralized web (Web3), MetaMask allows individuals to store crypto, send and receive tokens, trade assets, and participate in decentralized finance (DeFi) platforms directly from their browser.

Overview of MetaMask Extension

MetaMask is a self-custody wallet, meaning users retain complete control over their private keys and funds. Instead of storing assets on centralized exchanges, the extension encrypts private keys locally on the user’s device, enhancing privacy and security. It is available for major browsers such as Chrome, Firefox, Brave, and Microsoft Edge, making it widely accessible.

After installing the extension, users can create a new wallet or import an existing one using a 12-word secret recovery phrase. Once set up, MetaMask becomes a secure bridge between your browser and blockchain networks.
