Discover everything about the MetaMask Extension—its features, how to install it, and why it's the most popular crypto wallet for DeFi, NFTs, and Web3 apps. Learn how MetaMask empowers secure crypto access directly from your browser.
The MetaMask Extension is a powerful crypto wallet and gateway to decentralized applications (dApps), available directly within your web browser. Built as a browser plugin, MetaMask enables users to securely manage Ethereum-based assets, interact with DeFi protocols, mint NFTs, and explore Web3 without needing a centralized intermediary.
As of today, MetaMask is considered the most widely used Ethereum wallet globally, with over 30 million monthly active users and growing adoption across NFT markets, blockchain gaming, and financial dApps.
The MetaMask Extension is a browser-based Ethereum wallet that works as both a key vault and token manager. It allows users to store cryptocurrencies (mainly ERC-20 and ERC-721 tokens), manage wallet addresses, and interact with decentralized applications (dApps) such as Uniswap, OpenSea, Aave, Compound, and many others.
The extension is available for popular browsers like:
It supports Ethereum and Ethereum-compatible blockchains like Binance Smart Chain, Polygon, Arbitrum, Avalanche, Base, and more.
1. Non-Custodial Wallet
MetaMask gives users full control of their private keys and funds. It does not store any user data or credentials on centralized servers, making it a true non-custodial wallet.
2. Multi-Network Support
Although built for Ethereum, MetaMask can be configured to work with multiple EVM-compatible networks, including BNB Chain, Fantom, Avalanche, and Optimism.
3. One-Click dApp Access
MetaMask allows you to sign into dApps securely using your wallet. It replaces the need for usernames/passwords and enables one-click access to DeFi, NFT, and Web3 services.
4. Swapping & Bridging
Integrated token swapping allows users to exchange tokens without leaving the wallet. MetaMask aggregates prices from multiple DEXs like Uniswap, 1inch, and Paraswap to give the best available rates.
5. Custom Tokens & NFTs
Users can add custom tokens manually and manage their NFT collections within the wallet’s interface.
6. Hardware Wallet Integration
MetaMask supports integration with Ledger and Trezor, allowing for cold wallet access via a secure hardware device.
7. Secure Encryption & Backup
Wallet credentials are encrypted and stored locally in the browser. The recovery seed phrase is provided only once and must be securely backed up by the user.
Installing MetaMask is simple and only takes a few minutes:
After setup, your wallet will be ready to send, receive, and manage crypto or connect with dApps.
By default, MetaMask only supports Ethereum and ERC-20 tokens. However, you can manually add any EVM-compatible chain by entering the following:
