What Is an NFT?
An NFT, or Non-Fungible Token, is a unique digital asset verified using blockchain technology. Unlike cryptocurrencies such as Bitcoin or Ethereum—which are interchangeable—each NFT is one-of-a-kind. This makes them ideal for representing ownership of digital art, music, videos, and other creative works.
When you create an NFT, your file (image, audio, video) is uploaded and linked to a blockchain—typically Ethereum—where it receives a permanent, tamper-proof record of authenticity and ownership. This ensures your artwork cannot be copied, forged, or altered without detection.

Who Can Create an NFT?
Anyone can create an NFT. You don’t need advanced technical skills or coding knowledge. Whether you’re a digital illustrator, photographer, musician, or just someone with a creative idea, you can turn your work into a sellable NFT in minutes.
All you need is:
- A digital file (JPG, PNG, GIF, MP3, MP4, etc.)
- A cryptocurrency wallet (like MetaMask)
- Access to an NFT marketplace (like OpenSea)
- A small amount of ETH for gas fees (only during initial setup)
Let’s dive into the step-by-step process.
Step-by-Step Guide: How to Create Your First NFT
Step 1: Set Up a Crypto Exchange Account
Before you can mint an NFT on OpenSea, you’ll need Ethereum (ETH) to cover initial gas fees—the transaction costs on the Ethereum network.
We recommend using a reliable exchange that supports TWD deposits and withdrawals for seamless funding. Once registered, you can purchase ETH directly with your local currency.
After buying ETH, transfer it to your digital wallet to use on OpenSea.

Step 2: Install and Set Up MetaMask Wallet
MetaMask is one of the most popular crypto wallets used for interacting with Ethereum-based platforms like OpenSea.
How to Set Up MetaMask:
- Download the Extension: Go to metamask.io and install the browser extension (available for Chrome, Firefox, and Brave).
- Create a New Wallet: Click “Create a Wallet” and agree to the terms.
- Set a Strong Password: Choose a secure password you won’t forget.
- Backup Your Secret Recovery Phrase: This 12-word phrase lets you recover your wallet if you lose access. Never share it with anyone.
- Confirm Your Phrase: Re-enter the words in order to verify your backup.
- Finish Setup: Your wallet is now ready to use.
Once set up, send ETH from your exchange account to your MetaMask wallet using the public address.
Step 3: Connect MetaMask to OpenSea
OpenSea is the largest NFT marketplace, supporting a wide range of file types and offering an intuitive interface.
How to Connect:
- Visit opensea.io
- Click the wallet icon in the top-right corner
- Select MetaMask from the list
- Confirm the connection in your MetaMask extension
That’s it—you’re now logged into OpenSea without needing a traditional username or password.
Step 4: Create Your NFT Collection
A Collection is like your personal gallery on OpenSea where all your NFTs will live.
To Create a Collection:
- Click your profile icon → My Collections → Create a new collection
- Upload a logo, featured image, and banner
- Enter your collection name and description
- Choose the blockchain (recommended: Ethereum)
- Save your collection
Now you’re ready to add your first item.
Step 5: Upload and Mint Your NFT
- Inside your collection, click Add Item
- Upload your file (supports JPG, PNG, GIF, MP3, MP4, SVG, WAV, OGG)
Fill in details:
- Name
- Description
- External link (optional)
- Properties (traits like color, style, rarity)
- Unlockable content (e.g., bonus files accessible after purchase)
- Select Ethereum as the blockchain
- Click Create
This first-time setup requires an Ethereum transaction (gas fee), which only needs to be done once per wallet.
Step 6: List Your NFT for Sale
Once your NFT is created, you can list it for sale.
How to Sell:
- Click Sell on your NFT
- Set a fixed price in ETH
- Choose listing duration (1 day to 6 months)
- Confirm the transaction in MetaMask
OpenSea charges a 2.5% service fee on sales—no upfront cost to list.
After signing the transaction, your NFT will appear publicly on the marketplace.
Frequently Asked Questions (FAQ)
Q: How much does it cost to create an NFT?
A: The initial setup on OpenSea requires a one-time gas fee (paid in ETH). After that, minting is free ("lazy minting"). Costs vary depending on Ethereum network congestion but typically range from $10–$50.
Q: Can I create an NFT for free?
A: Yes! OpenSea allows "lazy minting," meaning you don’t pay gas fees until someone buys your NFT. The buyer covers the transaction cost.
Q: Which blockchain should I use for my NFT?
A: Ethereum is the most established and widely supported. Alternatives like Polygon offer lower fees but less visibility.
Q: What file types are supported?
A: OpenSea supports JPG, PNG, GIF, MP4, MP3, WAV, SVG, and more. Max file size is 100 MB.
Q: Can I edit my NFT after minting?
A: Yes—you can update pricing, metadata, and unlockable content at any time before or after sale.
Q: Is my NFT protected by copyright?
A: Minting an NFT doesn’t automatically grant copyright. You retain intellectual property rights unless explicitly transferred in the sale terms.
