The MetaMask Extension is a widely used browser-based cryptocurrency wallet that enables users to store digital assets and interact with decentralized applications (dApps). Acting as a gateway to the decentralized web (Web3), it allows individuals to send and receive cryptocurrencies, trade tokens, manage NFTs, and access decentralized finance (DeFi) platforms directly from their browser.

Overview of MetaMask Extension

MetaMask is a self-custody wallet, meaning users retain full control over their private keys and funds. Instead of relying on centralized exchanges, the extension stores encrypted keys locally on the user’s device, enhancing privacy and security. It is available for major browsers including Chrome, Firefox, Brave, and Microsoft Edge, making it one of the most accessible Web3 wallets available today.

Once installed, users can create a new wallet or import an existing one using a 12-word secret recovery phrase. After setup, the extension connects your browser to blockchain networks, enabling seamless interaction with Web3 platforms.
