The MetaMask Extension is one of the most widely used browser-based cryptocurrency wallets, designed to provide secure access to digital assets and decentralized applications (dApps). It serves as a gateway to the decentralized web (Web3), allowing users to store cryptocurrencies, interact with smart contracts, trade tokens, and explore decentralized finance (DeFi) platforms directly from their browser.
Overview of MetaMask Extension
MetaMask is a self-custody wallet, meaning users maintain 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, ensuring privacy and security. Available for browsers such as Chrome, Firefox, Brave, and Edge, MetaMask enables seamless interaction with the Ethereum blockchain and other compatible networks.
After installation, users can create a new wallet or import an existing one using a secret recovery phrase. Once set up, the extension allows quick access to Web3 services and blockchain-based applications.
