MetaMask Extension – Your Gateway to Secure Crypto and Web3

MetaMask Extension

A Secure Web3 Wallet for Browsers

The MetaMask Extension is a widely used browser-based cryptocurrency wallet that allows users to interact with blockchain networks directly from their web browser. Designed as a non-custodial wallet, MetaMask gives you full control over your private keys and digital assets without relying on centralized intermediaries.

Available for popular browsers such as Google Chrome, Brave, Edge, and Firefox, the MetaMask extension serves as both a crypto wallet and a gateway to decentralized applications (dApps).

What Is MetaMask Extension?

MetaMask is a software wallet that enables users to:

  • Store Ethereum (ETH) and ERC-20 tokens
  • Connect to decentralized finance (DeFi) platforms
  • Buy, send, and receive cryptocurrency
  • Manage NFTs
  • Interact with Web3 applications
  • Add custom blockchain networks

Because it is non-custodial, only you have access to your secret recovery phrase and private keys.

How MetaMask Works

When you install the MetaMask extension:

  1. A wallet is generated in your browser.
  2. You receive a 12-word secret recovery phrase.
  3. Your private keys are encrypted and stored locally on your device.
  4. You set a password to unlock the extension.

MetaMask then acts as a secure bridge between your browser and blockchain networks, allowing you to approve transactions and connect to decentralized applications.
