Five cats slipped out. Press and hold a card to decrypt it. Drag them around the desk. The art reveals itself, the rarity never does.

traditional nfts vs zama cats

What if rare
meant secret?

Traditional NFTs make rarity completely transparent. Zama Cats keep traits as encrypted values on-chain. The smart contract can still compute with them, without ever decrypting them in public.

Cat duel,
computed in the dark

Fully Homomorphic Encryption lets a smart contract compute on data it can't read. Try it: give your cat a secret power, seal it, and let the contract decide who wins. You learn the result. You never learn the rival's number. Neither does anyone else.
