Step-by-Step Guide to Buying an NFT on OpenSea (for Beginners)
If you’ve never bought anything on OpenSea, here’s exactly how to set up everything and make a purchase, assuming you already know the NFT you want.
1. Set Up a Crypto Wallet (If You Don't Have One)
To buy an NFT, you need a crypto wallet. The most popular choice is MetaMask.
How to Install MetaMask (Chrome & Mobile)
Go to MetaMask.io
Click "Download" and install it for Chrome, iOS or Android.
Follow the steps to create a new wallet.
Write down your Secret Recovery Phrase (12 words) → DO NOT SHARE IT WITH ANYONE.
Once set up, your MetaMask wallet is now ready!
2. Buy Cryptocurrency (ETH or MATIC)
Since OpenSea runs on Ethereum (ETH) and Polygon (MATIC), you need the correct cryptocurrency before buying an NFT.
Option 1: Use MoonPay (Easiest)
You can buy crypto with a credit/debit card using MoonPay:
Go to MoonPay.
Select Ethereum (ETH) or Polygon (MATIC) (based on the NFT you're buying).
Enter the amount you need.
Paste your MetaMask wallet address into MoonPay.
Complete the purchase with your credit/debit card.
The crypto will be sent to your MetaMask wallet within minutes.
Option 2: Use a Crypto Exchange (Cheaper but More Steps)
Sign up for Coinbase, Binance, Kraken, or another exchange.
Buy ETH using a bank transfer or credit card.
Withdraw it to your MetaMask wallet.
3. Connect Your Wallet to OpenSea
Now that you have your MetaMask wallet and crypto, connect it to OpenSea:
Go to OpenSea.io.
Click "Wallet" (top-right) and select MetaMask.
A MetaMask popup will appear → Click "Next", then "Connect".
Your wallet is now linked, and your profile is created automatically.
4. Find the NFT You Want to Buy ( The “T8020”)
Now that you're logged in:
Search for the NFT in the OpenSea search bar.
Click on the NFT listing you want to buy.
Check:
Blockchain: Ethereum (Make sure you have the right crypto).
Price: Listed in ETH
Seller: Verify that it's from the official collection.
5. Buy the NFT
You have two ways to buy an NFT on OpenSea:
Option 1: Buy Now (Fixed Price)
If the NFT has a "Buy Now" button, click it.
Click "Confirm Checkout"
MetaMask will pop up → Click "Confirm" to approve the transaction.
Wait for confirmation. Once approved, the NFT is now yours!
Option 2: Place a Bid (If It's an Auction)
If the NFT is up for auction, you must place a bid.
Click "Make Offer".
Enter your bid amount in WETH (Wrapped ETH).
Click "Convert ETH to WETH" if needed.
MetaMask will pop up to approve the transaction.
If the seller accepts your bid, you’ll win the NFT.
6. View Your NFT
After purchase, go to:
Profile → "Collected" Tab → You’ll see your new NFT!
7. (Optional) Transfer or Sell Your NFT
To send it to someone, click the "Transfer" button.
To resell it, click "Sell", set your price, and list it.
