What is an NFT? A plain-words guide

If you’ve ever wondered what people actually mean by “NFT,” this is the no-jargon version, plus how it works on KURV.

The short answer

An NFT is a record on a blockchain that says this specific piece belongs to this wallet. “Non-fungible” just means it isn’t interchangeable. One dollar is the same as any other dollar, but piece #42 of a collection is not the same as piece #7.

Think of it as a numbered certificate that lives on a public network anyone can check, instead of in someone’s filing cabinet.

What’s actually “in” an NFT

This part confuses a lot of people, so let’s split it into two pieces:

The record on chain. That’s the part that says who holds piece #42 and which collection it belongs to. It’s written to the network and anyone can look it up.
The art and its labels. The image and a small labels file (the name and traits) usually live somewhere else and are pointed to by the record. On KURV, images and labels are published to IPFS, a public file network, before a collection is launched.

KURV also records a fingerprint of the whole build on chain when it’s launched, so anyone can check that the files match what was recorded.

One honest caveat from the KURV docs: IPFS files stay available only while someone keeps them pinned. Freezing a collection makes the link to the files permanent, not the files themselves.

Collections, pieces and traits

Most NFTs come in collections: a set of pieces that share a style and a name. Each piece has a number, and often traits (like background: sunset, eyes: sleepy, hat: crown).

A lot of collections are generative: the artist draws layers (background, body, eyes, hat…) and software combines them into lots of different pieces. Max Cat, the cat you see on kurv.fun’s homepage, is built from seven layers: background, fur, head, eyes, nose, whiskers and frame.

On KURV a collection can be:

built from layers (KURV combines them for you),
finished art you made one piece at a time, or
an existing collection brought over from another NFT platform on Base.

Pieces can be still or animated images.

What does “mint” mean?

Minting is creating a piece’s record on chain and sending it to your wallet. When a collection is “minting,” it means people can buy new pieces straight from the collection, usually in order. On KURV you get the next piece in line.

We go through it step by step in How to mint an NFT on KURV.

What you need to hold one

A wallet: your account on the network. On KURV you don’t need to install anything, because logging in makes a wallet for you. More on that in What is a crypto wallet?.

Where does a collection live?

Every collection lives on a blockchain network. KURV runs on testnet today, on Base Sepolia and Solana Devnet, where coins are free and nothing has value. Creators pick which one their collection lives on when they launch it, and a piece always stays on the network its collection was put on. When you hold a piece, it sits at your wallet address on that network. More in Base and Solana basics.

What an NFT is not

Not a promise of value. What a piece sells for is up to the market. KURV’s docs say it plainly: “Every price, return and buyer is up to the market.”
Not automatically copyright. Holding a piece usually doesn’t give you the rights to the art. Those depend on what the creator offers.
Not risk-free. Contracts are programs, and the docs note that “contracts can have bugs, and a bug can lose money.” Read Risks and disclaimer before you mint or buy.

Where KURV fits

KURV is a platform and marketplace for NFT collections. The pitch is putting NFTs out the way you’d put out a meme coin: a short path from art to an open sale. One thing that’s different: every collection launched on KURV has its own Vault, which can hold money and pieces for that collection. Whenever it holds money, a holder can sell a piece back to it at that moment’s Vault Exit. That’s a quote at a moment, not a promise. We cover it in its own Learn article.
