The MetaMask Extension is a widely-used crypto wallet and Web3 browser extension that allows users to interact with decentralized applications (dApps) directly from their web browsers. Designed for ease of use and robust security, MetaMask is compatible with major browsers like Chrome, Firefox, Brave, and Edge. Whether you're trading tokens, minting NFTs, or participating in DeFi protocols, MetaMask serves as your bridge to the blockchain world.
MetaMask was developed by Consensys, a blockchain software company focused on Ethereum infrastructure and decentralized protocols. As of now, MetaMask boasts tens of millions of users worldwide, making it one of the most trusted non-custodial wallets available.
1. Non-Custodial Wallet
MetaMask gives you full control over your crypto assets. Unlike centralized exchanges, your private keys and funds are managed only by you, not by third-party services.
2. Multi-Network Support
Though originally built for Ethereum, MetaMask supports a growing list of Ethereum-compatible blockchains such as Binance Smart Chain (BSC), Polygon, Arbitrum, Optimism, and more. Users can manually add custom networks via the interface or use automatic integration through platforms like Chainlist.
3. Integrated Token Swap
With MetaMask Swap, users can easily trade tokens across multiple decentralized exchanges (DEXs) directly from their wallet. It offers competitive prices by aggregating quotes from multiple liquidity sources.
4. Secure Identity Vault
MetaMask securely stores user credentials and private keys in an encrypted format, accessible only through the extension and protected by a password and optional biometric authentication (on mobile).
5. Custom Gas Fee Settings
Users can adjust gas fees according to their preferences – whether they want faster transaction times or lower costs. The extension provides real-time gas estimates to help you make informed decisions.
6. NFT and Token Management
MetaMask automatically detects supported ERC-20 and ERC-721 tokens. It also allows users to manually add custom tokens to track their holdings in one place.
