MetaMask Extension – Your Gateway to Web3 and Decentralized Apps
The MetaMask Extension is a browser-based cryptocurrency wallet that allows users to store digital assets, manage tokens, and connect to decentralized applications (dApps) directly from their web browser. It is one of the most widely used Web3 wallets and acts as a bridge between traditional browsers and blockchain networks like Ethereum.
MetaMask is a self-custody wallet, meaning users control their private keys and funds instead of relying on a centralized platform.
MetaMask gives users full control over their wallet, private keys, and recovery phrase.
The extension allows seamless access to:
DeFi platforms
NFT marketplaces
Blockchain games
Decentralized exchanges (DEXs)
MetaMask supports multiple blockchain networks, including:
Ethereum
Polygon
Binance Smart Chain (BSC)
Avalanche (custom networks supported)
Users can store, send, and receive thousands of ERC-20 and compatible tokens directly in the wallet.
MetaMask allows users to swap tokens inside the extension without leaving the wallet interface.
