- Browser Integration: MetaMask is primarily known as a browser extension that allows users to interact with Ethereum-based decentralized applications (DApps) directly from their web browsers, such as Google Chrome, Mozilla Firefox, and Brave.
- Wallet Functionality: MetaMask serves as a cryptocurrency wallet that allows users to store, send, and receive Ether (ETH), as well as various Ethereum-based tokens (ERC-20 and ERC-721). It is a non-custodial wallet, meaning users have full control over their private keys.
- DApp Integration: MetaMask's primary function is to enable users to interact with Ethereum DApps seamlessly. When users visit a DApp that is integrated with MetaMask, they can log in, approve transactions, and manage their Ethereum assets directly through the extension.
- Security: Security is a top priority for MetaMask. Users are required to set up secure passwords and store their recovery seed phrases in a safe place. Transactions must be confirmed within the extension, adding an extra layer of security.
- Network Support: MetaMask supports various Ethereum networks, including the Ethereum mainnet and different testnets (e.g., Ropsten, Rinkeby, and Kovan). Users can also add custom networks for specific purposes.
- Privacy Features: The extension includes privacy features like built-in tracking protection to enhance user privacy while browsing and using DApps.
