MetaMask Extension is the leading crypto wallet and gateway to blockchain apps, seamlessly integrated into your browser. Designed for simplicity, security, and accessibility, MetaMask empowers users to interact with Ethereum and other EVM-compatible networks directly from Chrome, Firefox, Edge, and Brave.
MetaMask is a browser-based crypto wallet that enables users to store, manage, and interact with digital assets and decentralized applications (dApps). Available as a browser extension, MetaMask transforms your web browser into a powerful Web3 interface. Whether you want to buy NFTs, interact with DeFi protocols, or send and receive crypto, MetaMask is your go-to tool.
Launched by Consensys, MetaMask has become a cornerstone in the decentralized internet. Its intuitive design, secure architecture, and robust development tools have made it the most widely used Ethereum wallet in the world.
MetaMask gives you complete control over your funds. You hold the private keys — not an exchange, not a bank. This self-custody model is crucial for privacy and security.
While MetaMask started with Ethereum, it now supports a range of blockchains like Binance Smart Chain (BSC), Polygon, Avalanche, Arbitrum, Optimism, Base, and more. You can easily add custom networks manually or through one-click integration.
MetaMask connects directly with dApps, DeFi platforms, NFT marketplaces like OpenSea, and blockchain games such as Axie Infinity. With a few clicks, users can approve transactions, swap tokens, and sign smart contracts.
MetaMask allows users to swap cryptocurrencies directly within the wallet interface. By aggregating data from multiple DEXs, it ensures users get the best available price and lowest gas fees.
Use the MetaMask Extension on your browser and sync it with the MetaMask mobile app to manage your crypto on the go. The wallet syncs your accounts and transactions seamlessly.
When you install the MetaMask Extension, it injects a Web3 object into your browser. This enables websites to detect MetaMask and request interaction. For example, when a dApp needs access to your wallet for a transaction, it sends a request that you must manually approve.
Behind the scenes, MetaMask uses JavaScript APIs to interact with the Ethereum blockchain and compatible networks. It signs transactions locally, meaning your private keys never leave your device — a core security feature.
