Enter a LEO Cat number to see it, check anything you like, then inscribe its permanent Xtrata twin in one click. We handle the chain reads, image fetch and hash check for you.
Enter a LEO Cat number above and select “Show me this cat”.
Pick any LEO Cat number to see it. You can browse as many as you like before choosing one to make permanent.
Connect your wallet to see whether a cat is already in it — you’re welcome to inscribe its twin either way.

Technical details & on-chain proof
Everything here runs automatically when you load a cat — it follows the source token URI to its metadata, fetches the raw image, hashes it, and checks the hash against the canonical record seeded on-chain. It is shown so anyone can verify the chain reads and the exact bytes being inscribed. You don’t need to touch it.

Canonical inscription · Xtrata core contractResolve a token to read its canonical inscription from the Xtrata core.
Load a cat to check whether its image hash matches the canonical hash seeded in the helper contract.
Build collection hash manifest
Batch mode can follow the LEO Cats token URI through metadata, or use a direct raw image template once one has been identified. Chain URI mode is safest for a new collection because it reads from the source contract first.
Ready. Set a range, then build the manifest.

Cache-first source collection view. Tiles resolve from the on-chain LEO Cats token URI through metadata JSON, then reuse cached image URLs on later loads.

How It Works
Three steps. We do the first two for you.
01
Pick a cat
Type any LEO Cat number. We load it straight from the chain and show you the artwork — browse as many as you like.
02
We verify it
Behind the scenes we fetch the cat’s real image and confirm it matches the canonical hash sealed on-chain. No files to upload.
03
Inscribe its twin
One click opens your wallet to create the permanent Xtrata twin. Later, the cat’s owner can swap which side stays liquid.
