Solana Cat — catalogued as "Cat NFT"
Maker unknown, c. 2024 or earlier
Portable Network Graphic, 32 × 32 px, 448 bytes
Palette: six pigments, cadmium-yellow on sky blue
Medium: bytes, held in a Solana mint account
Endowment: 0.01516584 SOL, deposited once, in perpetuity
Accessioned 17 August 2026, 15:21:56 UTC, slot 439,874,759. Permanent installation. Not available for loan.

A museum with one object and no walls.

The object is not photographed here. It is pulled out of the vault and redrawn in your browser every time this page loads. There is no copy of it on this server.

01provenance

Three custodians. The same 448 bytes.

A provenance is the chain of hands a work has passed through. This one is short, public, and ends on a public ledger.

c. 2024
origin

Studio material

The file ships with Solana's official developer course as the sample image for the token-metadata lesson: src/cat.png. It was never meant to be looked at — it was the stand-in picture you replace with your own. Every developer who follows that chapter mints this exact cat, then forgets it.

2024
first sale

Removed from the studio

Someone found it in the repository linked from Solana's own site and issued it as a coin. It traded, then it didn't. The picture itself was never on the chain: it hung on a server, on loan, revocable by whoever paid the hosting bill.

17 Aug 2026
accession

Acquired for the collection

At 15:21:56 UTC, in slot 439,874,759, the object was installed inside a Solana mint account — the bytes themselves, not a reference to them — and the storage was endowed in perpetuity. It cannot be moved, recalled, or taken down. Two further transactions, two seconds later, hung the picture and filed the catalogue entry.

03pigment analysis

Six colours. Counted pixel by pixel.

Conservation begins with knowing exactly what a thing is made of. The object was decoded to raw pixels in your browser and every one of its 1,024 pixels was sorted by colour.

04conservation method

Every other work in this medium hangs by a link.

the usual practice

A token stores a web address. That address returns a small text file. The text file names another address, and that one holds the picture — on a company's disk, behind a bill somebody has to keep paying.

minthttps://…/metadata.jsonhttps://…/image.pngsomebody's server (until it isn't)

Three hops, each one owned by someone. When any of them lapses the token keeps trading and its face turns into a broken image. That is the normal condition of the medium.

this accession

The 448 bytes are written into the token's own mint account as on-chain metadata, and the storage is prepaid for good. There is no hop. There is no host. There is no bill.

mintthe bytes (that's the whole diagram)

To destroy this object you would have to stop Solana. To verify it you need one free network call — which is exactly what this page did, in front of you, a moment ago.

A picture that gets used should be a picture that survives.

We did not make this cat, and we claim no rights in it. It was a placeholder in a tutorial — the least important file in the repository — and it has since been looked at more than most art. So we paid the storage, wrote the bytes into the chain, and left the doors open.

Open always. Admission is one RPC call.

Always

The vault has no door, no guard and no closing time. It is replicated on every Solana validator in the world.

Free

One getAccountInfo call to any public node. No wallet, no sign-in, no ticket.

Encouraged

Copy the bytes. Hash them. Print them. The object does not degrade from being looked at.

06the gift shop

The object is free. The souvenir is not.

Every museum ends in a gift shop. Ours sells one thing: a meme coin with the cat on it, trading on pump.fun. It is a souvenir. The cat stays free to look at either way, and you can verify it before you spend anything.

01A souvenir confers no ownership of the object. The object belongs to no one; that is the point of it.
02There is no team, no roadmap, and no promise of value. The shop is a joke told with a straight face.
03The souvenir's picture is also this cat. Unlike the object, the souvenir's copy lives on a server — which is the entire argument of this museum.
