Metamask® Extension | Getting started with Metamask®

MetaMask® is your gateway to the decentralized web, serving as both a secure cryptocurrency wallet and a bridge to interact with blockchain applications. Trusted by millions, MetaMask® empowers you to manage digital assets, swap tokens, and explore Web3 with complete control.

Two Core Components:

  1. MetaMask® Extension:
    The browser-based interface (Chrome, Firefox, Brave, Edge). Install it to manage assets and interact with dApps directly from your desktop.
  • Official Download: Always get it from metamask.io → "Download" → Select your browser (e.g., MetaMask® Chrome Extension).
  1. MetaMask® Mobile App:
    The full-featured wallet for iOS and Android. Download from Apple App Store or Google Play.

Getting Started with MetaMask®:

  1. Download:
  • Extension: Visit metamask.io/download.html. Click your browser icon (e.g., Chrome). Follow store prompts to add the MetaMask Wallet Extension.
  • Mobile App: Search "MetaMask Wallet" in your device's official app store.
  1. Create a New Wallet:
  • Open the Extension or App. Click "Create a New Wallet".
  • Crucial: Write down your 12-word Secret Recovery Phrase (SRP) on paper. Store it offline, never digitally. This is your master key!
  • Confirm the SRP. Set a strong MetaMask® password (this encrypts access locally on your device/browser).
  1. MetaMask® Login:
  • Extension: Click the MetaMask® fox icon in your browser toolbar. Enter your password.
  • Mobile App: Open the app, enter your password.
  • Note: This password unlocks the local interface. Your funds are secured by your SRP.

Key Features Accessible via MetaMask®:

  • Asset Management: View ETH and tokens across networks (Ethereum, Polygon, BNB Smart Chain, etc.).
  • dApp Interaction: Seamlessly connect to DeFi protocols, NFT marketplaces, and games. Approve transactions securely.
  • Token Swaps: Swap tokens directly within the wallet using built-in aggregators (fees apply).
  • Buy Crypto: Purchase ETH with fiat via integrated partners (e.g., Transak, MoonPay).
  • Bridge Assets: Move tokens between different blockchains.
  • Network Management: Easily add custom EVM-compatible networks (use caution!).

Security First:

  • You control your keys: Your SRP generates your private keys, stored only on your device. MetaMask® never holds custody.
  • Transaction Confirmations: Review all transaction details carefully before approving within the Extension or App.
  • Phishing Warnings: MetaMask® displays alerts for known malicious sites.

MetaMask® FAQ: Essential Answers

  1. Q: How do I install the MetaMask® Chrome Extension?
  • A: Go ONLY to metamask.io/download.html. Click the Chrome icon. This redirects to the official Chrome Web Store listing. Click "Add to Chrome".
  1. Q: Is it safe to use the MetaMask® Extension?
  • A: The official extension/app from metamask.io is safe. Security depends on YOU: Guard your SRP fiercely, use strong unique passwords, enable auto-lock, bookmark dApp URLs, and never enter your SRP anywhere except the official wallet during restore.
  1. Q: I forgot my MetaMask® password. How do I recover my wallet?
  • A: Your password only protects local access. It does NOT lock your funds. Uninstall/reinstall the Extension or App. Select "Import using Secret Recovery Phrase". Enter your 12-word SRP. Set a new password. Never share your SRP!
  1. Q: Can I use the same wallet on Extension and Mobile?
  • A: Yes! Use your SRP to import your existing wallet into the other platform (Mobile or Extension). Go to Settings → Security → "Reveal Secret Recovery Phrase" on the device where the wallet is active (authenticate). Then import it on the new device.
  1. Q: Why do I need the Extension and the Mobile App?
  • A: They serve the same core wallet function but on different devices. The Extension is essential for interacting with dApps in your desktop browser. The Mobile App provides full wallet management on your phone and can connect to mobile dApps via WalletConnect. Many users utilize both.
  1. Q: A dApp is asking to connect to my MetaMask® Wallet. Is this safe?
  • A: Connecting only shares your public address. Always verify the dApp's URL is correct before connecting. Be extremely cautious when a connected dApp asks you to sign a transaction. Review every detail shown in your MetaMask® pop-up before approving.
