Setting Up MetaMask for the First Time

Step 1: Open MetaMask

    • MetaMask will ask for feedback to improve the service. Choose "I agree" or "No thanks" as per your preference.

    • Create a strong password for your wallet and click "Create".

    • MetaMask will generate a 12-word secret recovery phrase. Write this down and store it in a safe place. You will need this to recover your wallet if you forget your password or lose access to your device.

    • Click "All Done" to complete the setup.

  2. Import Wallet:

    • Click "Import Wallet".

    • Agree to the terms and conditions, then click "Import".

Using MetaMask

Step 1: Access Your Wallet

  1. After setup or import, you will be taken to your wallet dashboard. Here you can see your account balance, transaction history, and tokens.

Step 2: Managing Assets

  1. Add Tokens: Click on "Add Token" to add custom tokens to your wallet.

  2. Send/Receive: Use the "Send" button to transfer tokens to another address, and the "Receive" button to get your public address for receiving tokens.

Step 3: Connect to dApps

  1. When you visit a dApp (like Uniswap or OpenSea), you will often see a "Connect to Wallet" button. Clicking this will prompt MetaMask to connect.

  2. Permissions: Review and grant permissions to the dApp as needed.

Security Tips

  2. Password: Use a strong, unique password for your MetaMask wallet.

  3. Phishing Attacks: Be cautious of phishing attacks. Only enter your password and recovery phrase on the official MetaMask extension or website.

  4. Regular Backups: Regularly back up your secret recovery phrase and any private keys.
