🔶 How to Install the MetaMask Wallet Extension

Installing MetaMask is a quick and easy process. Just follow these steps:

Step 1: Go to the Official Website

🔶 How to Create a New MetaMask Wallet

After installing the extension, it will guide you through creating a wallet.

1. Click “Get Started”

This opens the setup screen.

2. Choose “Create a Wallet”

If you already have a wallet, you can choose “Import Wallet” using your recovery phrase.
