NFTs, or Non-Fungible Tokens, are a way to own, trade, and interact with digital assets on a blockchain. They are used for art and music, in-game items, event tickets, and even wallet names, by creators, collectors, and builders alike.
What Does "Non-Fungible" Mean?
In simple terms, non-fungible means unique.
- A $1 bill is fungible: you can trade it for another $1 bill and it holds the same value.
- A piece of art, a limited-edition sneaker, or a concert ticket is non-fungible. It's one-of-a-kind and can't be swapped one-for-one with something else.
An NFT is a token that records who owns one specific item. The image attached to it can be copied by anyone; the token itself can't, and it sits in one wallet at a time.1
How NFTs Work
NFTs are stored on a blockchain, a shared digital ledger that anyone can check. On Cardano, an NFT is a token with a quantity of one, created under a set of rules that stops anyone from making more.1
Each Cardano token carries a policy ID, a unique code that identifies the rules (the minting policy) it was created under. Anyone can give a token any name, but only the original creator's policy produces that policy ID, so it is how you tell a real NFT from a copy.2
An NFT also carries metadata: its name, description, traits, and a link to its image. Most Cardano NFTs record this metadata in the transaction that creates them, following a community standard called CIP-25. A newer standard, CIP-68, keeps the metadata on a paired reference token that the creator can update later, which suits game items and other NFTs that change over time.3 The metadata links to the image rather than holding the file itself, often through IPFS, a decentralized file storage network.4
Why Cardano's Native Token Approach Matters
On Ethereum, each NFT collection runs on its own smart contract, and every transfer is a call to that contract.5 Cardano treats NFTs as native tokens: the ledger tracks them directly, the same way it tracks ADA.5 This has practical effects:
- Lower fees. Sending an NFT works like sending ADA, so it costs the same as an ADA transfer.6
- No separate contract to trust. A basic transfer runs no smart contract code, so there is no extra contract whose bugs could put the token at risk.6
- Wallet support. Because tokens live in the same ledger records as ADA, Cardano wallets can hold and send them alongside ADA.5
One thing to know: an NFT never travels alone. Every wallet record that holds a token must also hold a minimum amount of ADA, roughly 1 to 2 ADA for a single NFT, and that ADA moves with it.5
What Can Be an NFT?
Just about anything digital can be minted (created) as an NFT:
- Digital art
- Music and audio files
- Gaming assets
- Virtual land
- Collectible cards
- Wallet names, similar to domain names
- Event tickets
- Certificates and documents
How to Mint Your Own NFT on Cardano
You don't need to write code to create an NFT on Cardano. You need your digital file, some ADA for fees, and a minting platform.
The basic minting process:
- Connect your Cardano wallet to a minting platform
- Upload your digital file (image, video, audio, etc.)
- Add metadata (name, description, attributes)
- Choose the quantity, and a royalty rate if you want one
- Pay the fees and confirm the transaction in your wallet
- Your NFT is created and sent to your wallet
You usually pay three things: the Cardano network fee (a fraction of an ADA for a simple transaction), the platform's own fee, and the minimum ADA that travels with the NFT. Each platform publishes its fees; NMKR's pricing page, for example, lists all three.7
A minting policy can include a time lock. After the lock date, the policy accepts no new tokens, even from the creator, and that is how a fixed supply is proven.8
A royalty is a percentage of each resale paid back to the creator. On Cardano it is recorded in the collection's metadata under a standard called CIP-27, and marketplaces that follow the standard pay it.3 Only the first royalty record minted under a collection's policy counts, so the creator can't raise the rate later.9
Cardano NFT minting platforms:
- NMKR: Upload your files to NMKR Studio by drag-and-drop, or use its API for larger projects. It supports both CIP-25 and CIP-68.10
- CNFTlab Party: Minting with a wallet login and no account details, at 1 ADA per NFT. It handles single NFTs, collections of up to 10 per transaction, and CIP-68.11
Adastack lists more minting tools to compare.
Why Do NFTs Matter?
NFTs bring provable ownership, scarcity, and traceability to digital items. With an NFT, you can:
- Own a digital item and prove it's yours
- Buy or sell it peer-to-peer, without needing a middleman
- Support creators directly, through first sales and royalties
- Keep it in your own wallet, separate from any one app or marketplace
Where Can You Buy or Sell NFTs?
On Cardano, you buy and sell NFTs on NFT marketplaces, such as:
- Wayup: A Cardano NFT marketplace that also gathers listings from other marketplaces, so you can search them in one place12
- CSwap NFT Marketplace: An NFT marketplace from the CSwap DEX team where collections can be paired with ADA in liquidity pools, so you can buy from or sell into a pool at its current price13
You'll need a Cardano wallet (like VESPR, Eternl, or Lace) connected to interact with these platforms. New to wallets? Start with how to set up a Cardano wallet.
Your NFTs live on Cardano, not on the marketplace, so they stay in your wallet even if a marketplace closes. When JPG Store shut down its platform, its smart contracts stayed live, and its open listings can still be reached through other marketplaces or the Cardano command-line tools.14
Are NFTs Safe?
NFTs are as safe as the wallet and platform you use. Always:
- Use trusted wallets and marketplaces
- Never share your seed phrase (the recovery words for your wallet)
- Check the policy ID before buying. Anyone can mint a token with the same name and picture, but only the real collection has its policy ID. Compare it with the one the project publishes on its official site or social accounts.2
Real-World Use Cases for NFTs
NFTs aren't just for art. They're also used for:
- Proof of ownership of physical goods and real-world assets
- Records of sustainability efforts, such as tree planting
- Event ticketing and access passes
- Supply chain tracking
- On-chain certificates, credentials, and identity
Notable NFT Projects on Cardano
These collections and campaigns show the range of NFTs on Cardano:
SpaceBudz
SpaceBudz launched in March 2021 as a set of 10,000 astronaut animals, each with its own traits.15 It was an early user of the CIP-25 metadata standard16 and later moved its collection to CIP-68.17 One of its co-founders, Alessandro Konrad, co-authored both standards.18,19,20
Clay Nation
Clay Nation's 10,000 characters are assembled from traits sculpted by hand in clay.21 The team is building a virtual festival world around the characters, and its site lets you explore the concept art, environments, and 3D assets made so far.22
Book.io
This project sells eBooks and audiobooks as NFTs. The NFT holds the key that unlocks the encrypted book, so only the owner can read or listen to it.23 The project made its first sale on Cardano in July 2022.24
Veritree
Veritree ran Cardano Forest, a completed tree-planting campaign, with the Cardano Foundation.25 Donors received tokens that each stood for a planted tree and could swap them for NFTs recording their donation.25 The campaign reached its goal of 1 million trees planted.26
ADA Handle
ADA Handle turns long Cardano wallet addresses into short names that start with $, such as $alice. Each Handle is an NFT, and payments sent to the name go to whichever wallet holds it.27
