What is an NFT? Understanding the Basics

Non-fungible tokens, or NFTs, have transformed the digital world by allowing unique ownership of digital goods such as art, music, collectibles, and more. But what is an NFT exactly, and what makes it different from cryptocurrencies? Simply put, an NFT is a blockchain-based digital certificate of ownership, proving that a file—whether art, a tweet, or a game asset—is one-of-a-kind and belongs to you.

NFT meaning comes from their non-fungible nature, which means each token is distinct and cannot be exchanged on a 1:1 basis like cryptocurrencies such as Bitcoin or Ethereum.

NFT art, collectibles, and music files represent popular use cases. For creators, NFTs offer a way to monetize digital work directly, while buyers can collect, trade, or display exclusive digital items.

OKX supports beginner education and provides a safe entry into NFTs with easy-to-understand resources, making your first steps hassle-free.

NFTs vs. Cryptocurrencies

NFTs are unique and non-interchangeable, whereas cryptocurrencies like Bitcoin and Ethereum are fungible and act as digital currencies. With NFTs, you own a specific asset, not just a unit of value. This uniqueness means NFT ownership is verifiable and tradeable on the blockchain, and that's the fundamental reason behind their value.

Top NFT Examples

Some of the most well-known NFT projects include:

• CryptoPunks: Iconic pixel art collectibles.
• Bored Ape Yacht Club: Unique, limited-edition digital apes with perks.
• NBA Top Shot: Video highlights as collectible sports cards.
• Music NFTs: Songs and albums by artists like 3LAU and Kings of Leon.

These projects show the variety and potential of NFTs in today's digital economy.

Step 1: Create or Choose Your NFT

Before you can sell NFT art, music, or other content, you need to either create your own digital asset or select an original file to tokenize. NFT platforms support formats such as PNG, JPG, GIF, MP4, MP3, and more. Be mindful: high-quality, original work tends to attract more buyers.

Remember the basics—don’t copy someone else’s work, and always respect intellectual property and copyright laws. If you’re selling something you didn’t create, you’ll need proof you have rights to that file.

OKX makes it simple for creators to start, supporting multiple digital file types and easy onboarding with clear instructions.

Create Digital Art or Collectible

Here’s a quick checklist for new NFT creators:

• Decide on your asset: Art, music, animation, video, collectible card, etc.
• Ensure your file is high-resolution and original.
• Choose a supported format: JPEG, PNG, GIF, MP4 for video, MP3 for audio.
• Prepare a brief description and title for your NFT.

💡 Pro Tip: Adding a detailed, engaging backstory or meaning to your NFT can increase its value and buyer interest!

Verify Ownership & Copyright

Before listing or minting, verify you have the right to sell the file. Research local laws and consider adding a license or copyright statement in your NFT’s metadata for clarity.

Step 2: Set Up Your Wallet

To sell NFT assets, you need a crypto wallet that supports NFT standards. Wallets store your assets and enable transactions on NFT marketplaces.

There are two main types of wallets: custodial (where a platform helps manage your keys) and non-custodial (where you control your keys directly). Custodial wallets are beginner-friendly, while non-custodial options offer more control but require careful management.

OKX offers an integrated wallet solution, blending easy setup with layered security—including encrypted backups and multifactor authentication for peace of mind.

Custodial vs. Non-Custodial Wallets

• Custodial wallets: Security handled by the platform, quick recovery options, ideal for beginners.
• Non-custodial wallets: You own the private keys—more responsibility, but total control.
• ✅ Main difference: Security and responsibility. Decide what fits your experience and comfort level.

Funding Your Wallet for NFT Sales

To sell or mint an NFT, you typically need a small amount of cryptocurrency to cover transaction (gas) fees. You can fund your wallet by:

• Buying crypto directly by bank or card on the marketplace
• Transferring crypto from another wallet or exchange
• Using integrated services like OKX for seamless purchasing

💡 Pro Tip: Always enable 2FA and back up your wallet recovery phrase in a safe location. Never share your keys with anyone.

Step 3: Mint Your NFT

Minting is the process of publishing your digital file as a verified asset on the blockchain. Once minted, your NFT is tradable and uniquely tied to your crypto wallet.

To mint NFT, you’ll upload your chosen file, fill in metadata (title, description), select your blockchain, and pay a small fee called 'minting cost' or 'gas'.

On OKX, the minting process is streamlined, with clear instructions and low, transparent fees, allowing you to focus on creativity, not complexity.

Choosing a Blockchain

Popular blockchains for NFTs include:

• Ethereum: Most widely supported, but can have high gas fees.
• Polygon: Lower fees, eco-friendly, compatible with Ethereum infrastructure.
• OKX: Fast, low-cost transactions, beginner-friendly UX.

Each blockchain has its strengths. Beginners often prefer low-fee options like Polygon and OKX.

Metadata and Unlockable Content

When minting, you’ll be prompted to enter:

• Title and description: Describe your NFT and its story.
• Royalties: Specify a percentage cut you'll receive from future sales.
• Unlockable content: (Optional) Add secret files, download links, or exclusives for your buyer.
• Tags and attributes: Help users find your NFT in marketplace searches.

Step 4: List and Sell Your NFT

Once your NFT is minted, it’s time to list it for sale. Understanding how to sell NFT means knowing your options: fixed price or auction, choosing the right platform, and promoting your work.

OKX’s step-by-step selling flow is ideal for beginners and integrates handy marketing and analytics tools.

Pricing Your NFT: Fixed vs. Auction

You can set your NFT sale as:

• Fixed price: Set your price, and anyone can buy immediately (great for quick sales).
• Auction: Bidders compete, driving price higher. Useful for rare or highly desired items.

Example: Set a fixed price of 0.05 ETH ($125) for fast sales, or launch an auction with a starting bid of 0.01 ETH if you expect higher demand.

Listing Your NFT on OKX and Other Platforms

Steps for listing:

1. Connect your funded wallet to the NFT marketplace.
2. Choose your freshly minted NFT from your wallet.
3. Select “List for Sale.”
4. Enter your price or set auction parameters.
5. Confirm and pay any listing fees.

OKX enables cross-listing and helps you reach wider audiences. Leading platforms include OpenSea, Binance NFT, and NFTify—each with its own strengths.

Promoting Your Sale

To boost sales:

• Share your listing on Twitter, Instagram, Discord, and NFT communities.
• Ask friends and contacts to engage or share.
• Use OKX’s built-in marketing features like featured spots or collection highlights.

• Selling fees: Platforms take 1–2.5% cut on successful sales. OKX charges just 2%.

NFT Royalties and Secondary Sales
