Instead of relying on centralized exchanges, MetaMask allows users to hold their private keys, giving them complete control over their digital assets. The extension is available for popular browsers including Chrome, Firefox, Edge, and Brave, making it easy to access Web3 from any desktop environment.

How to Install the MetaMask Wallet Extension
Setting up the MetaMask Extension is simple and takes only a few minutes. Here are the steps:
Step 1: Visit the Official MetaMask Website
Open your browser and go to the official website. Always verify the URL manually to avoid phishing or scam sites imitating the MetaMask platform.
Step 2: Select Your Browser
Choose your browser type—Chrome, Firefox, Brave, or Edge—and click the button to install the extension. This redirects you to the respective browser’s extension store.
Step 3: Add the Extension
Click Add to Browser and confirm the installation. The MetaMask icon will appear in your browser toolbar once successfully installed.
Step 4: Create a New Wallet
Choose Create a Wallet. MetaMask will ask whether to share anonymous usage data—this step is optional.
Step 5: Set a Strong Password
Create a secure password that will unlock the wallet on your browser. This password is local to your device and cannot be used for account recovery.
Step 6: Backup Your Secret Recovery Phrase
MetaMask will provide a 12-word Secret Recovery Phrase. This is the most important part of your wallet setup. Write it down and store it somewhere safe and offline.
Never share your recovery phrase with anyone and never store it digitally unless encrypted.
Step 7: Complete Verification
Confirm the recovery phrase in the correct order. After verification, your wallet is ready to use.
