Non-fungible tokens (NFTs) are a specialized segment of the crypto market. You may have heard about digital art selling for large sums or seen brands launching NFT collections. You may wonder if these tokens are still relevant and whether they have any real value.
This guide covers what an NFT is, how NFT marketplaces work, how NFTs are used in art, and even how to create one.
What is an NFT?
An NFT is a type of digital asset that represents ownership of a unique item like art, music, or gaming collectibles. To fully understand this, it helps to break down the term:
-
Non-fungible means something that’s distinct and can’t be replaced with something identical. For example, a concert ticket (though not an NFT) is considered non-fungible because each ticket has a specific seat and value.
-
Token refers to a unique, digital identifier stored on a blockchain. Unlike a standard computer file that can be copied, a token can represent a single item or a numbered item in a limited series. We explain the role of the blockchain in NFTs later.
NFTs vs. cryptocurrencies
NFTs are often compared to cryptocurrencies like bitcoin, but they’re different because cryptocurrencies are fungible. One bitcoin is interchangeable for another bitcoin, but NFTs are distinct units. One NFT can’t be exchanged for another on a one-to-one basis because each contains unrepeatable data.
Plus, while you can buy a fraction of a cryptocurrency, an NFT is typically treated as a whole unit — you either own the token, or you don’t. However, the landscape of fractional NFTs is evolving.
How do NFTs work?
NFTs rely on a combination of blockchain technology and smart contracts, which act as the digital infrastructure for ownership.
The role of blockchains
A blockchain is a shared, decentralized digital ledger that records transactions across many computers. Because this ledger is public and permanent, anyone can verify who created a specific NFT and who owns it now. This makes the asset’s transaction history more transparent and much harder to forge.
Note that the blockchain doesn’t store the NFT itself; it only holds the individual identifier and metadata link that points to where the file is hosted.
What is a smart contract?
A smart contract is a self-executing program stored on the blockchain. Once the right conditions are met, for instance, a buyer sending the correct amount of crypto to buy something, the program automatically completes the transaction.
In the world of NFTs, smart contracts handle the heavy lifting:
-
They assign the unique Identifier to each token, ensuring no two are exactly alike.
-
They instantly update the ledger to show the new owner after a sale.
-
They can be programmed to pay the original NFT artist a percentage of every future resale (royalties), depending on the platform capabilities and marketplace rules.
The minting process
Creating an NFT is known as minting, a process that transforms a standard digital file into a distinctive cryptographic asset. It begins when a creator prepares their work (e.g., an image, video, or music file) and attaches metadata. This includes their name, a description, and a secure link to the high-resolution file.
While anyone can view or download the digital file linked to an NFT, only the wallet holding that specific token is recognized as the current owner.
The actual “mint” occurs when the creator’s digital wallet interacts with a smart contract to record the metadata and identifier onto the blockchain. To finalize this, network validators must verify the transaction — a step that often requires a small payment (called a gas fee) to cover the necessary computing power.
Once the transaction is confirmed, the NFT is officially born on the public ledger and appears in the owner’s digital wallet.
What is an NFT marketplace?
An NFT marketplace is an online platform where users can buy, sell, and trade NFTs. These platforms work similarly to online marketplaces for physical goods, but they’re built for digital assets.
For creators, these platforms provide the tools to mint NFTs without needing to write complex code; the marketplace handles the interaction with the smart contract on the creator’s behalf.
For buyers and collectors, marketplaces serve as a searchable directory of digital assets. Using advanced filters and categories, they can discover new artists or review an NFT’s transaction history and creator wallet details to help them assess authenticity.
Note: Before you can buy or sell an NFT, you must connect a compatible crypto wallet. This wallet holds the cryptocurrency needed for purchases and provides a secure place to store your NFTs after a transaction is finalized.
When storing your NFTs, always use a reputable wallet, keep your private keys secure, don’t share any sensitive info, and be cautious with unknown links and platforms.
What is NFT art?
NFT art is a digital collectible where the artwork’s certificate of authenticity is recorded on a blockchain. In the traditional art world, proving a masterpiece is genuine requires a paper trail of physical certificates and expert appraisals. NFT art replaces this manual process with a “digital deed” stored as data. This acts as the artwork’s DNA, containing the artist’s digital signature and the secure location of the file.
It’s important to distinguish between the art and the token. While the art itself is a digital file — such as a JPEG, a 3D model, or a high-definition video — the NFT is the unique token that proves you own that specific version. This distinction allows digital artists to create scarcity in a world where files are easily copied.
NFTs have opened the door for formats that don’t fit in a traditional frame. This includes generative art (created by code), programmable art that changes based on real-world data, and immersive 3D assets designed specifically for virtual galleries.
Unlike traditional art sales, where an artist never sees another cent after the first sale, NFT creators can program royalties into their work (though this is platform- and marketplace-dependent). This means a percentage of the sale price is funneled back to them every time the piece is traded between collectors in the future.
Unless a specific legal agreement is attached to the NFT, the copyright usually remains with the artist. So, you can display your NFT in a digital frame or use it as a social media avatar, but you generally can’t print it on merchandise or use the imagery for commercial gain. You own the specific edition of the art, but the artist still owns the underlying intellectual property.
Are NFTs still relevant?
NFTs remain relevant in some sectors, though enthusiasm is lower than in 2021 when NFTs were wildly popular for a time. Their relevance has shifted from art-only collectibles to functional digital tools. In 2026, the technology is often being used by major brands and industries for practical applications that don’t always make the headlines.
Here are some examples:
-
Digital identity and ticketing: Reduces fraud in event ticketing and secures digital credentials like diplomas.
-
Gaming assets: Allows players to own certain in-game items (e.g., skins, weapons, or land) that can be moved between different games.
-
Real-world asset (RWA) tokens: Links physical goods, like luxury watches or real estate, to a digital certificate of authenticity on a blockchain.
Are NFTs valuable?
The question of whether NFTs are valuable now depends on utility rather than just rarity. While most early speculative projects have lost their initial peak value, blue-chip collections and those with clear benefits remain highly sought after.
Several key factors now drive market value:
-
Utility and access: Does the NFT grant you entry to a community, a physical event, or a digital service?
-
Brand and reputation: High-value NFTs are often backed by established creators or companies with long-term roadmaps.
-
Scarcity and provenance: Just like traditional art, a limited supply from a verified historical creator still attracts collectors.
-
Institutional adoption: With over 40% of Fortune 500 companies now integrating NFTs into their loyalty programs or supply chains, institutional support has helped sustain demand for some NFT use cases.
The 2026 NFT market reality
A key takeaway is that the market has matured. The get-rich-quick volatility of 2021 has cooled into a $60 billion industry focused on long-term value. While you likely won’t see the same rapid, overnight price spikes of the past, the current focus on practical use cases could imply that the NFTs surviving today are built on more solid ground.
How to make an NFT: A step-by-step guide
Making an NFT is the act of publishing your digital work on a blockchain so it can be bought, sold, and tracked. While it sounds technical, most modern platforms have simplified this into a few easy steps.
Prepare your digital asset
Your NFT can be almost any high-quality file, such as:
-
High-resolution JPEGs, PNGs, or GIFs
-
MP4s for animations or WAV/MP3 files for music
-
GLB or GLTF files for use in 3D worlds
Choose your blockchain and wallet
The blockchain is the ledger where your NFT will live. Your choice here determines your transaction speed and cost. Examples include:
-
Ethereum: The most popular, but carries higher fees
-
Solana or Polygon: Fast, lower-fee with lower energy use and costs only a few cents to mint
Once you’ve picked a network, set up a wallet. As mentioned, it’ll act as your digital identity and your vault for storing both crypto and NFTs.
Fund your wallet
To interact with a blockchain, you need its native currency (like ETH for Ethereum or SOL for Solana). You’ll use this to pay gas fees — the small payments made to the network’s validators to process your minting request.
If you want to start for $0, look for platforms that offer “lazy minting.” This lets you list your NFT for free; the actual minting only happens (and the fee is paid) when someone buys the token.
Select a marketplace
Common examples include:
-
OpenSea: Arguably the largest NFT shopfront for beginners
-
Magic Eden: A popular marketplace for gaming assets and Solana-based art
-
Zora: A creator-first platform that often sponsors gas fees, making minting free
Mint your NFT
After connecting your wallet to the marketplace, click Create or Mint. You’ll be asked to:
-
Upload your file: This sends your work to a decentralized storage system.
-
Add metadata: Enter the title, description, and properties (rarity traits).
-
Set royalties (if allowed): Choose a percentage that you’ll automatically receive every time the NFT is resold in the future.
-
Sign the transaction: Your wallet will ask for a digital signature to authorize the mint.
List it for sale
Your NFT is now on the blockchain, but it isn’t for sale yet. You must list it by choosing a fixed price or a timed auction. This means users can either buy it instantly, or the NFT will go to the highest bidder at a later date. Once you confirm your choice, the NFT is live.
What is an NFT? FAQs
Can you lose money buying NFTs?
Yes, NFT prices can rise or fall sharply, and some tokens may become difficult to sell. As with any speculative asset, there’s a risk of losing some or all of your investment.
Do you need cryptocurrency to buy an NFT?
Often, yes. Many NFT marketplaces require payment in cryptocurrency, such as ethereum or solana. Some platforms also support credit card purchases or fiat payment options.
Can NFTs be copied or screenshotted?
The image or media linked to an NFT can usually be copied or screenshotted, but that doesn’t transfer ownership of the token. Ownership is recorded on the blockchain.
Are NFTs taxed?
In many countries, NFT sales or profits may create tax obligations. The rules depend on where you live and how you use or sell the NFT, so local guidance is important. Always consult a tax practitioner about your specific circumstances.
