Built to Last Forever

Permanently Preserved Pixels.

These creatures aren't hosted. They aren't stored. Every pixel, every trait, every name... Etched permanently into the Ethereum blockchain. No servers to shut down. No company to go bankrupt. Long after we're gone, the creatures remain. Built to outlast everything.

Sovereignty of the Commons.

Every CC0mon belongs to the world — legally, permanently, completely. Build the game. Print the merch. Write the lore. Remix the art. No permission needed. The creatures are yours to carry wherever you want to take them.

A Living Canon.

260 species. 10,000 tokens. An open mythology waiting for its next chapter, written by anyone. Build a game, forge a story, mint new lore. There are no gatekeepers here. The creatures belong to whoever carries them forward.

Developer Tooling

The CC0mon API

The data is open. The world is waiting. Every creature, trait, image, and owner record — no keys, no permission, no gatekeepers. Nine endpoints. Build anything from a single species page to an entire creature economy.
