MetaMask Wallet – The Gateway to Ethereum, Web3, and DeFi
MetaMask Wallet is one of the most widely used non-custodial cryptocurrency wallets in the world. Available as a browser extension and mobile app, MetaMask empowers users to manage their digital assets, interact with decentralized applications (dApps), explore DeFi (Decentralized Finance), buy and sell NFTs, and access the broader Web3 ecosystem with complete control over their private keys.
Created by ConsenSys in 2016, MetaMask has become the default wallet for anyone using the Ethereum blockchain and Ethereum-compatible networks like Polygon, BNB Smart Chain, Avalanche, and Arbitrum.
🔑 What Is MetaMask Wallet?
MetaMask is a non-custodial crypto wallet, which means you are the sole owner of your private keys and funds. Unlike centralized exchanges where you must trust the platform with your assets, MetaMask lets you create, import, and control your wallet directly from your browser or mobile device. No sign-up, no KYC, no middleman.
When you set up MetaMask, it creates a 12-word Secret Recovery Phrase (also called a seed phrase), which serves as your wallet’s backup. This phrase is the only way to restore your wallet if your device is lost or reset, so it must be kept safe and offline.
