A generative art NFT is a blockchain token associated with artwork made using an artist-designed system, such as rules or computer code. The system may use chance, but it does not have to. The token identifies the NFT; it does not necessarily contain the artwork or prove that the art is stored on the blockchain.
What makes art generative?
Generative describes a way of making art. The artist sets up a system—such as rules, instructions, or code—that produces or helps produce the work. The system may operate with some autonomy and may include randomness or chance. The Museum of Modern Art defines generative art as art created in part or whole through an autonomous system or computer code, often relying on chance; randomness is common, not a requirement. MoMA’s definition of generative art makes that distinction clear.

The Victoria and Albert Museum describes generative art as work made using a set of rules. It also distinguishes generative art as a kind of computer art, not a label for all art made with computers. In practice, the artist’s role can include designing the system and its constraints, while the system generates or shapes a particular output. The V&A’s digital art and design dictionary provides its definition.
What does the NFT add?
The NFT is a distinct token recorded and managed by a blockchain smart contract. It can provide a publicly verifiable token identity and ownership record on that blockchain. Ethereum.org describes NFTs as unique blockchain assets; an NFT may refer to an image or other media rather than contain it. Ethereum.org’s NFT overview explains the distinction between a token and the asset associated with it.

On Ethereum, an ERC-721 token is identified by its contract address together with its token ID. A project can also use a token ID as an input to generate an image, linking a particular token to a particular output. That is one possible design, not a feature required of every generative art NFT. Ethereum.org’s ERC-721 documentation describes these identifiers and token-based generation.
Is the artwork stored on the blockchain?
Not necessarily. The token, the generation code or algorithm, the image or other media, and the metadata that describes or locates that media can be stored in different places. Calling something a generative art NFT does not establish where any of these parts live.
MoMA uses “on-chain art” for NFTs whose smart contract and artwork media are written into the blockchain. That is a narrower description of storage, not a synonym for generative art NFT. OpenSea describes several arrangements, including fully on-chain content, on-chain metadata, decentralized storage, and centralized storage. MoMA’s explanation of on-chain art and OpenSea’s overview of NFT metadata describe these distinctions.
- Token identity: recorded on the relevant blockchain.
- Algorithm or code: may be on-chain or stored elsewhere.
- Artwork media: may be written into the blockchain or served from external storage.
- Metadata: may be on-chain or held in decentralized or centralized storage.
These pieces can have different storage arrangements within the same project, so check the project’s own documentation before assuming that a work is fully on-chain.

A project might use a token’s ID as an input to its generative system, so the system produces an output associated with that token. In another arrangement, the project’s algorithm may be on-chain while the resulting media is served externally. Neither arrangement makes the NFT token itself identical to the image.
OpenSea names Art Blocks as an example in which the algorithm is on-chain and media may be served externally. Musée d’Orsay describes Agoria’s works as existing on Tezos and being created with fx(hash) and Feral File. These are examples of particular project and platform arrangements, not a blueprint for every generative art NFT. OpenSea’s metadata explanation and Musée d’Orsay’s description of Agoria’s work provide those examples.

What does owning the token mean for the artwork?
Token ownership is not, by itself, proof that the holder owns the artwork’s copyright or has a complete license to reproduce it. The rights depend on the terms that apply to the particular work. Read the project’s license or sale terms rather than inferring permissions from the token record.
