MetaMask is a popular cryptocurrency wallet that works as a browser extension. It enables users to manage their Ethereum-based assets and interact with the Ethereum blockchain.
MetaMask can be installed as a browser extension for Chrome, Firefox, Brave, and Edge. There is also a mobile version available for iOS and Android. Upon installation, users create a new wallet or import an existing one using a seed phrase. A password is then set for local access to the wallet.
Users can send and receive funds, view transaction history, and manage their token portfolio. MetaMask automatically calculates gas fees, which can be adjusted based on transaction speed preferences.
MetaMask is one of the most widely supported wallets in the Ethereum ecosystem, with compatibility for numerous dApps and DeFi platforms.
Security features
During setup, MetaMask generates a 12-word seed phrase, which is crucial for wallet recovery. This phrase must be stored securely offline.
MetaMask integrates with hardware wallets like Ledger and Trezor, providing an extra layer of security by storing private keys offline.
Users can create multiple accounts within MetaMask. Each account generates a unique Ethereum address.
MetaMask includes a built-in phishing detector. It warns users if they attempt to visit known malicious sites.
