Key Features of MetaMask Extension

🦊 Secure Wallet for Ethereum and Beyond

MetaMask is not just a wallet—it’s a self-custody vault. Users retain full control of their private keys, ensuring true ownership of their digital assets. It supports Ethereum and thousands of ERC-20, ERC-721 (NFT), and other EVM-compatible tokens.

🌐 Seamless Web3 Browsing

MetaMask serves as a bridge between your browser and the decentralized internet. You can connect to dApps like Uniswap, OpenSea, Aave, and more with a single click. It makes interacting with smart contracts and DeFi platforms intuitive, safe, and efficient.

🔐 Enhanced Privacy and Security

MetaMask doesn’t store your personal data. Everything is encrypted and stored locally in your browser. With password protection and seed phrase backups, users can safely manage their accounts. The extension also alerts users to phishing sites and malicious actors.

💱 Built-In Swaps & Token Management

With the MetaMask Swaps feature, users can exchange one crypto token for another directly within the extension. It aggregates prices from multiple DEXs to provide the best rates, minimizing slippage and maximizing value.
