• Extensive community support

Step 1: Install MetaMask

For Chrome Users:

1. Go to metamask.io
2. Click “Download”
3. Select “Install MetaMask for Chrome”
4. Click “Add to Chrome” in the Chrome Web Store
5. Click “Add Extension” when prompted

Step 2: Create Your Wallet

1. Click the MetaMask icon in your browser toolbar
2. Click “Get Started”
3. Select “Create a Wallet”
4. Choose whether to help improve MetaMask (optional)
5. Create a strong password
   • Use at least 8 characters
   • Include numbers and special characters
   • Don’t use the same password for other accounts

Step 3: Secure Your Seed Phrase

This is the most important step for your wallet security!

What is a Seed Phrase?

A seed phrase (also called recovery phrase) is a series of 12 words that can restore your entire wallet. It’s your ultimate backup.

Steps:

1. Click “Reveal Secret Words”
2. Write down all 12 words in the exact order shown
3. Use pen and paper - never store digitally
4. Verify the phrase by clicking words in correct order
5. Store your paper safely - consider multiple copies in different locations

Critical Security Rules:

• ❌ Never store seed phrase on computer/phone
• ❌ Never share with anyone (MetaMask will never ask for it)
• ❌ Never enter it on websites or apps
• ✅ Keep multiple physical copies in secure locations
• ✅ Consider using a fireproof safe

Step 4: Explore Your Wallet

Congratulations! Your wallet is now created. Let’s explore the interface:

Main Screen Elements:

• Account name: Shows your current account (Account 1)
• Balance: Shows your ETH balance
• Account address: Your public address for receiving funds
• Send/Receive buttons: For transactions

Key Features:

• Networks: Switch between different blockchains
• Assets: View your token holdings
• Activity: Transaction history
• Settings: Wallet configuration options

Step 5: Get Your First Crypto (Testnet)

Before using real money, let’s practice with test ETH:

Switch to Goerli Testnet:

1. Click the network dropdown (shows “Ethereum Mainnet”)
2. Select “Show/hide test networks”
3. Toggle on “Show test networks”
4. Select “Goerli Test Network”

Get Test ETH:

1. Copy your wallet address (click the address to copy)
2. Go to goerlifaucet.com
3. Paste your address and request test ETH
4. Wait for the transaction to complete
5. Check your MetaMask - you should see test ETH!

Step 6: Your First Transaction

Let’s practice sending crypto on the testnet:

Send Test ETH:

1. Click “Send” in MetaMask
2. Enter a recipient address (you can send to yourself)
3. Enter amount (try 0.01 ETH)
4. Review gas fees
5. Click “Confirm” to send
6. Wait for confirmation

Understanding Gas Fees:

• Gas: Computational effort required for transactions
• Gas Price: How much you pay per unit of gas
• Gas Limit: Maximum gas you’re willing to use
• Total Fee: Gas Price × Gas Used

Step 7: Security Best Practices

Now that your wallet is set up, follow these security practices:

Immediate Actions:

• Verify your seed phrase backup is secure
• Set up additional security (if available)
• Bookmark the official MetaMask website
• Never share your seed phrase or private keys

Ongoing Security:

• Keep MetaMask updated
• Be cautious of phishing websites
• Double-check addresses before sending
• Start with small amounts when trying new protocols

Step 8: Connect to Your First DApp

Let’s connect to Uniswap to see how DApps work:

1. Go to app.uniswap.org
2. Click “Connect Wallet”
3. Select “MetaMask”
4. Approve the connection in MetaMask
5. You’re now connected to Uniswap!

Note: You’re still on testnet, so you won’t be using real money.

Troubleshooting Common Issues

MetaMask Not Appearing:

• Check if extension is enabled
• Try refreshing the page
• Look for the fox icon in your extensions

Can’t See Test ETH:

• Ensure you’re on Goerli testnet
• Wait a few minutes for transactions to process
• Try a different faucet if one doesn’t work

Transaction Stuck:

• Check if you have enough ETH for gas fees
• Try increasing gas price
• Wait longer - network might be congested
