Where has this picture hung before?
Hand us a token address. We take its logo's fingerprint and lay out every recent launch that carried the same picture, or one nearly like it, in the order they appeared. The earliest is usually the original; the rest are copies.
Counting the archive…
The finding
The examined piece and every launch in the archive whose fingerprint matches it, earliest first.
Nothing on the easel yet. Examine a token or an image above.
Most copied, last 24 hours
Pictures that more than one launch hung up in the past day, with an identical fingerprint.

Catalogue notes
How a picture is fingerprinted and compared, and what that can and cannot tell you.
How the archive grows
Every 20 seconds we read Jupiter's open listing of fresh, nearly-graduated and just-graduated launches across Solana launchpads, and fingerprint the logo of each token we have not met before. It is a sample rather than a census: a coin that appears and vanishes between two reads will be missed.
The fingerprint
Each logo is reduced to 72×64 greyscale by the public image service wsrv.nl (IPFS art through open IPFS gateways), averaged into a 9×8 grid, and every cell is asked whether it is darker than its neighbour to the right. Those 64 answers form the dark-and-light grid shown on each plaque.
Reading a match
Two fingerprints are laid side by side and the disagreeing cells counted. Up to 2: the same picture, merely re-saved, resized or recompressed. 3 to 8: a close variant, such as a new border, a tint or a small edit. Flat single-colour images are set aside, since they all resemble one another.
What leaves your device
A file you choose is fingerprinted inside your browser and never uploaded; we receive only its 16-character code. A pasted link is fetched by our server from public https hosts only (no private networks, images only, 3 MB at most) and then fingerprinted in your browser. Being earliest is a hint, not a deed of ownership.
