🦊 MetaMask Extension – Your Gateway to the Decentralized Web

The MetaMask Extension is a widely used crypto wallet and gateway to blockchain applications, built specifically for web browsers. Available for Chrome, Firefox, Edge, and Brave, the MetaMask Extension allows users to securely manage cryptocurrencies, interact with decentralized applications (dApps), and explore the world of Web3 — all from the convenience of their browser.

Since its launch in 2016 by ConsenSys, MetaMask has become one of the most popular self-custody wallets for Ethereum and other blockchain networks. It is especially known for its role in enabling DeFi, NFTs, and blockchain gaming.

🌟 Key Features of the MetaMask Extension

🔐 Self-Custody Crypto Wallet

MetaMask is a non-custodial wallet, meaning you have full control over your private keys and digital assets. No third party can access your funds as long as you safely store your seed phrase.

🌐 Web3 and dApp Access
