What Is the MetaMask Wallet?
MetaMask is an open-source cryptocurrency wallet that functions as a browser extension and mobile app. It allows users to store, send, receive, and swap digital assets across various blockchain networks — primarily Ethereum and EVM-compatible chains like Polygon, Binance Smart Chain, and Arbitrum.
As a non-custodial wallet, MetaMask gives you full control over your private keys and funds. This means no third party can freeze or recover your account — great for privacy, but it also places responsibility for security directly on you.
Because of its seamless integration with thousands of decentralized applications (dApps), MetaMask has become the go-to wallet for engaging with DeFi protocols, staking platforms, NFT marketplaces, and more.
Why Use MetaMask?
- Free to download and use
- Available as browser extension (Chrome, Firefox, Edge) and mobile app (iOS, Android)
- Supports multiple blockchains and tokens (ERC-20, ERC-721, etc.)
- User-friendly interface ideal for beginners
- Enables direct interaction with dApps without managing complex infrastructure

Step 2: Choose Your Platform
Select the version that matches your device:
- Browser Extension (for Chrome, Firefox, Brave, Edge)
- Mobile App (iOS or Android)
For this guide, we’ll focus on the browser extension (Chrome).
Step 3: Install the Extension
After clicking “Install MetaMask for Chrome,” you'll be redirected to the Chrome Web Store. Click “Add to Chrome”, then confirm by selecting “Add Extension.”
Once installed, the fox icon will appear in your browser’s toolbar.
Step 4: Launch MetaMask
Click the MetaMask icon in your extensions menu. A setup window will open in a new tab.
Click “Get Started” to begin the wallet creation process.
Step 5: Create a New Wallet
Choose “Create a Wallet” if you’re setting up for the first time. If you already have a seed phrase from another device, select “Import Wallet.”
Step 6: Set a Strong Password
Enter a secure password. This password encrypts your local data and is required every time you open MetaMask — but it does not recover your wallet. Only your seed phrase can do that.
Accept the terms of use and proceed.
Step 7: Secure Your Secret Recovery Phrase
You’ll be shown a 12-word recovery phrase (seed phrase). This is the master key to your wallet.
📌 Critical Security Tips:
- Write it down on paper — never store it digitally (no screenshots, cloud notes, emails).
- Keep it offline and in a safe place.
- Never share it with anyone — not even support teams.
Click the lock icon to reveal the words, then click “Next.”
Step 8: Confirm Your Seed Phrase
Re-enter the 12 words in the correct order to verify you’ve saved them properly.
If successful, you’ll see a confirmation message: “Congratulations!”
Click “All Done” — your wallet is now ready to use.
