NFTs, or non-fungible tokens, are blockchain-based tokens that prove ownership and provenance of digital items such as images, video files, and even physical assets.
They’ve gained immense popularity recently, with multi-million dollar sales of NFT artwork making headlines. Twitter profiles flaunt NFT avatars like Bored Ape Yacht Club, CryptoPunks, and Pudgy Penguins. Even major brands and celebrities have embraced NFTs—but how do you create one?
Minting an NFT ("creating on the blockchain") is straightforward with this beginner-friendly guide. We’ll focus on Ethereum, the leading blockchain for NFTs, and OpenSea, the top NFT marketplace.
Step 1: Get a Crypto Exchange Account
To mint an NFT—or engage in crypto—you’ll need an account on a crypto exchange like Coinbase or Kraken. These platforms let you buy and sell cryptocurrencies.
Why? You’ll need Ethereum (ETH) to pay for minting fees (explained later). Plus, if your NFT sells, you can cash out or trade earnings.

Step 2: Buy Ethereum
Most NFTs are built on Ethereum, the second-largest cryptocurrency. Buy ETH on your exchange; it’s widely listed.
Why Ethereum?
NFT marketplaces (like OpenSea) require ETH for:
- Initialization: A one-time sign-up fee paid in ETH.
- Gas fees: Transaction costs that fluctuate ($30–$300).
Step 3: Set Up a Crypto Wallet
NFT marketplaces connect to crypto wallets. The most popular is MetaMask, a browser extension for Chrome/Brave.
How to Install MetaMask:
- Download MetaMask.
- Create a password.
- Note your 12-word recovery phrase (store it securely!).
Avoid buying ETH directly via MetaMask—exchange fees are lower.
Step 4: Transfer Ethereum to Your Wallet
Send ETH from your exchange to MetaMask:
- On the exchange, navigate to "Withdraw."
- Enter your MetaMask public address (starts with "0x").
- Confirm the transaction.
Step 5: Sign Up for OpenSea
- Unlock MetaMask (click the fox icon).
- Visit OpenSea.
- Click "Profile" → "Connect Wallet" → MetaMask.
- Sign terms via MetaMask and verify your email.
Step 6: Mint Your NFT
- Click "Create" (top-right).
- Upload your file (image, video, etc.).
- Name your NFT and add a description (optional).
- Click "Create"—your NFT is minted!
👉 Pro tip: Optimize NFT listings for visibility
Listing for Sale:
- Choose fixed price (buyer pays gas) or auction (seller pays gas).
- OpenSea charges a 2.5% commission on sales.
Alternative NFT Marketplaces
While OpenSea dominates, consider:
| Marketplace | Fees |
|------------|------|
| Rarible | 2.5% (buyer + seller) |
| SuperRare | 3% (buyer) |
| Foundation | 15% (seller) |
Minting on Other Blockchains

- Flow: Home to NBA Top Shot.
FAQ
1. How much does it cost to mint an NFT?
Gas fees vary ($30–$300). Fixed-price listings avoid seller fees.
2. Can I change my NFT after minting?
No—NFTs are immutable. Verify files before minting.
3. Which blockchain is best for NFTs?
Ethereum has the largest ecosystem, but Solana offers lower fees.
4. Do I own copyright if I buy an NFT?
No—ownership ≠ copyright. Check the NFT’s terms.
Final Tips
- Start with low-value NFTs to practice.
- Research gas fees (Etherscan Gas Tracker).
