How to Set Up MetaMask in 2026: Complete Beginner's Guide

MetaMask is the most popular crypto wallet in the world with over 30 million users. Here's how to set it up properly and securely.

Step 1: Install MetaMask

1. Go to metamask.io (verify the URL carefully — use our Risk Scanner if unsure)
2. Click "Download" and install the browser extension for Chrome, Firefox, Brave, or Edge
3. You can also install the MetaMask mobile app for iOS or Android

Warning: Only install MetaMask from the official website or your browser's official extension store. Never install from a link someone sends you.

Step 2: Create your wallet

1. Click "Create a new wallet"
2. Set a strong password (this only protects the app, not your funds — your seed phrase is what matters)
3. Write down your 12-word seed phrase on paper — not in a file, not a screenshot, not in notes
4. Verify your seed phrase by selecting the words in the correct order
5. Your wallet is created

Step 3: Secure your wallet

• Back up your seed phrase in at least 2 physical locations
• Enable password lock — set a short auto-lock timer
• Consider a hardware wallet for amounts over $500 — see our Hardware Wallet Quiz
• Never share your seed phrase — not with MetaMask support, not with anyone

Run our Security Checklist to make sure you haven't missed anything.

Step 4: Add networks

MetaMask comes with Ethereum by default. To use cheaper L2 networks:

1. Click the network dropdown (top of MetaMask)
2. Click "Add network"
3. Popular networks to add: Arbitrum One, Base, Optimism, Polygon

Check which networks your wallet supports with our Wallet Compatibility Checker.

Step 5: Your first transaction

1. Get some ETH — buy on an exchange and withdraw to your MetaMask address
2. Always send a small test amount first — $5-10 to verify everything works
3. Check gas fees — use Should I Send Now? to check if it's a good time
4. Practice in our sandbox — try our Crypto Sandbox to practice without real money

MetaMask security tips

• Check the URL before every transaction — phishing sites look identical to real ones
• Don't approve unlimited token allowances — use our Signature Decoder to understand what you're approving
• Regularly review connected sites — disconnect sites you no longer use (Settings → Connected Sites)
• Use a hardware wallet for large amounts — MetaMask connects to both Ledger and Trezor
