The MetaMask Chrome extension is one of the most popular cryptocurrency wallets, designed to give users easy and secure access to Ethereum and other EVM-compatible blockchains directly from their web browser. It acts as a bridge between your browser and decentralized applications (dApps), allowing seamless interaction with Web3 platforms, NFTs, and DeFi protocols.

This guide explains what the MetaMask Chrome extension is, how to install and use it, key features, and best security practices.

What Is MetaMask Chrome Extension?

MetaMask is a non-custodial wallet, which means you control your private keys. Unlike centralized exchanges, MetaMask does not store your funds. The Chrome extension allows you to:

  • Store Ethereum (ETH) and ERC-20 tokens
  • Send and receive crypto directly from your browser
  • Connect to decentralized applications (dApps)
  • Buy crypto with fiat using integrated providers
  • Manage NFTs and DeFi assets

By using the MetaMask Chrome extension, users can access Web3 platforms without relying on external applications or mobile wallets.

  5. Choose “Create a Wallet” if you’re new, or “Import Wallet” if you already have a recovery phrase
  6. Set a strong password for browser access
  7. Securely back up your 12-word Secret Recovery Phrase
