🔐 What Is MetaMask?

MetaMask is a crypto wallet and browser extension (also available as a mobile app) that allows you to:

  • Manage Ethereum-based assets (ETH, ERC-20 tokens, NFTs)
  • Interact with decentralized apps (dApps)
  • Store private keys securely
  • Send and receive crypto

✅ Step-by-Step: Getting Started with MetaMask

🔹 Step 1: Install MetaMask

On Desktop:

  1. Go to the official site: https://metamask.io
  2. Click "Download".
  3. Choose your browser: Chrome, Firefox, Edge, or Brave.
  4. Add the MetaMask extension.

On Mobile:

  1. Open the App Store (iOS) or Google Play Store (Android).
  2. Search for MetaMask.
  3. Download and install the app.
⚠️ Always verify you're using the official MetaMask site or app to avoid phishing scams.

🔹 Step 2: Create a New Wallet

  1. Open MetaMask.
  2. Click “Get Started”.
  3. Choose “Create a Wallet”.
  4. Set a strong password.
  5. Agree to the terms and continue.

🔹 Step 3: Backup Your Secret Recovery Phrase

  • MetaMask gives you a 12-word Secret Recovery Phrase.
  • Write it down and store it offline (never share this with anyone!).
  • Confirm your phrase to continue.
🛡️ Anyone with access to this phrase can access your wallet. Keep it safe.

🔹 Step 4: Using MetaMask

🪙 Add Funds:

  • You can receive ETH or other tokens by clicking “Receive” and sharing your wallet address.
  • You can buy ETH via MetaMask (with card, bank, etc., using third-party providers like Transak or MoonPay).

🔁 Send Crypto:

  • Click “Send”, paste the recipient’s address, choose the amount, and confirm.

🔌 Connect to dApps:

  • Visit a dApp (like OpenSea, Uniswap, etc.)
  • Click “Connect Wallet”, choose MetaMask, and approve the connection.

🔹 Step 5: Custom Networks (Optional)

MetaMask supports more than just Ethereum mainnet. You can add:

  • Polygon (MATIC)
  • Binance Smart Chain (BSC)
  • Arbitrum, Optimism, and more

To do this:

  1. Click on the network dropdown at the top.
  2. Select “Add network”.
  3. Enter the details (you can find them on the official site of the network).

🧠 Tips for Safe Use

  • Never share your Secret Recovery Phrase or private key.
  • Only interact with trusted dApps.
  • Use a hardware wallet for higher-value storage (e.g., Ledger + MetaMask).
  • Consider setting up a second browser profile or wallet for testing purposes.
