The MetaMask Extension is a browser-based cryptocurrency wallet that allows users to interact with the Ethereum blockchain and decentralized applications (dApps) directly from their web browser. As the most popular Web3 wallet, it serves as a bridge between traditional browsers and the emerging decentralized web.
Available primarily as a MetaMask Chrome Extension (with support for other Chromium-based browsers like Brave, Edge, and Firefox), this tool enables users to manage their Ethereum-based assets, interact with smart contracts, and access the growing ecosystem of decentralized finance (DeFi) platforms and dApps without running a full Ethereum node.
The MetaMask Wallet functionality allows users to securely store, send, and receive Ethereum and ERC-20 tokens. Your private keys are encrypted and stored locally on your device, giving you complete control over your assets.
Seamlessly interact with decentralized applications without leaving your browser. The extension injects a Web3 API into websites, allowing them to communicate with the Ethereum blockchain through your wallet.
Access not only the Ethereum mainnet but also various test networks and popular Ethereum-compatible chains like Binance Smart Chain, Polygon, Avalanche, and more through custom RPC settings.
Built-in swap functionality allows users to exchange tokens directly within the extension, aggregating rates from various decentralized exchanges to find the best prices.
Connect popular hardware wallets like Ledger® and Trezor® for enhanced security, keeping your private keys offline while using MetaMask® as the interface.
