🐱 DN404 · Ethereum · pixel cats on-chain

10,000 pixel cats,
real on OpenSea.

CateCoin is a DN404 hybrid. Buying is a cheap, plain ERC-20 swap. Opt in whenever you want, and your pixel cat is drawn entirely on Ethereum, and shows up as a real NFT on OpenSea, Etherscan and every wallet. No IPFS.

CateCoin #5 · Legendary
why it is different

Cheap to buy. Real cats.

Most on-chain ERC-404s can't show their art on marketplaces. CateCoin is DN404, so the cats are actual, indexable NFTs.

Real NFTs on OpenSea

A DN404 mirror emits proper ERC-721 events and ERC-165, so once you opt in your cat shows up on OpenSea, Etherscan and every wallet.

Buying stays cheap

skipNFT is on by default, so a buy is a plain ERC-20 transfer, no NFT minted, no gas bomb. Reveal your cats only when you want.

Art lives on-chain

Each pixel cat is generated by a renderer contract from its token id. The image and traits come off the chain itself, forever.

Meet the cats

Every cat is unique: fur, eyes, background, a tabby pattern, and rare touches like a collar, shades or a golden crown.

These are real outputs from the renderer contract, decoded straight from tokenURI. Nothing here is a mockup.

Buy $CATE

Trade either side

Sell the token any time, or list the cat as an NFT. Opt back out to go pure fungible.
