How to Install and Create a MetaMask Wallet
Step 1: Install the MetaMask Browser Extension
To get started, install MetaMask as a browser extension. Compatible with Chrome, Firefox, Brave, and Opera, this example uses Google Chrome:
- Visit the official site at metamask.io/download
- Click on “Chrome” and select Install MetaMask for Chrome
- Confirm by clicking “Add to Chrome”
- Finalize by selecting “Add extension”
✅ Security Tip: Always verify you're downloading from the official MetaMask website to avoid phishing scams.
Once installed, a fox icon will appear in your browser’s extension menu.
Step 2: Set Up Your MetaMask Account
Now that the extension is installed:
- Click the puzzle (or fox) icon in your browser toolbar
- Select MetaMask to open the setup window
- Click Get Started
- Choose Create a Wallet
- Create a strong password — avoid reusing passwords from other accounts
- Accept the Terms of Use and proceed
You’ll then be shown a 12-word recovery phrase (also known as seed phrase). This is the key to restoring your wallet if you lose access.
🔐 Critical Security Advice:
- Never share this phrase with anyone
- Write it down on paper and store it in a secure location
- Do not save it digitally (e.g., screenshots, notes apps)
After saving your phrase, confirm it by selecting the words in order. Once verified, your wallet is ready to use.
How to Find Your Wallet Address (Public Key)
Your public key, or wallet address, is what others need to send you ETH or NFTs. It's safe to share — unlike your private key or recovery phrase.
To find your address:
- Open MetaMask
- Click on your account name at the top
- Your public address appears below — click the copy icon to save it to clipboard
You can now use this address to receive Ethereum or withdraw funds from exchanges.
Adding Ethereum (ETH) to Your Wallet
To buy or mint AI art NFTs, you’ll need ETH for gas fees and purchases.
Option 1: Buy ETH via Exchange
- Sign up on a regulated exchange like Coinbase or Kraken
- Complete identity verification
- Purchase ETH using fiat currency (USD, EUR, etc.)
Option 2: Transfer ETH to MetaMask
Once you have ETH in your exchange account:
- Go to the Withdraw section
- Select Ethereum (ERC-20)
- Paste your MetaMask public address into the recipient field
- Confirm transaction
⚠️ Always send a small test transaction first to ensure accuracy.
ETH transfers may take several minutes depending on network congestion. Once received, your balance will appear in MetaMask under the Ethereum Mainnet.

Add Polygon Network for Lower-Cost NFT Transactions
Minting and trading NFTs on Ethereum can incur high gas fees. The Polygon network (formerly Matic) offers a scalable, low-cost alternative while remaining fully compatible with platforms like OpenSea.
Here’s how to add Polygon to MetaMask:
- Open MetaMask
- Click the network dropdown (default: Ethereum Mainnet)
- Select Add Network
- Enter the following details:
Network Name: Polygon Mainnet
New RPC URL: https://polygon-rpc.com/
Chain ID: 137
Currency Symbol: MATIC
Block Explorer URL: https://polygonscan.com- Click Save
You’re now connected to Polygon! You can switch between Ethereum and Polygon anytime within MetaMask.
To use Polygon, you’ll need MATIC tokens to cover transaction fees. You can buy MATIC directly on exchanges or bridge ETH from Ethereum to Polygon using the official Polygon Bridge.
Ready to Mint AI Art NFTs?
With your MetaMask wallet funded and configured for both Ethereum and Polygon, you're fully equipped to explore the world of AI-generated NFT art.
Platforms like OpenSea allow you to:
- Mint original AI artworks
- List them for sale

- Explore trending AI artists
Whether you're creating surreal visuals with generative models or collecting algorithmically crafted pieces, your wallet is your gateway.
Frequently Asked Questions (FAQ)
Q: Is MetaMask safe for storing NFTs?
A: Yes — as long as you protect your 12-word recovery phrase and never share it. Since MetaMask is non-custodial, only you control your assets.
Q: Can I use MetaMask on mobile?
A: Absolutely. Download the MetaMask app from the App Store or Google Play to manage your wallet on iOS or Android devices.
Q: Why should I use Polygon instead of Ethereum?
A: Polygon offers significantly lower transaction fees and faster processing times, making it ideal for frequent NFT creators and buyers.
Q: What happens if I lose my recovery phrase?
A: Unfortunately, there’s no way to recover your wallet without it. Always back it up securely during setup.
Q: Can I have multiple wallets in MetaMask?
A: Yes — MetaMask allows you to create or import multiple accounts within the same extension or app.
Q: Do I need ETH to use Polygon?
