Where it came from

Created outside Bitcoin Universe by The CAT protocol community, 2024.

Where the specification lives

CAT-721 has no Bitcoin Universe specification repository. Its specification is Maintained upstream.

Bitcoin Universe indexes or implements it in bitcoinuniverseio/index-cat20.

Support in Bitcoin Universe products

CAT-721 has no marketplace entry in the Core protocol registry, so no Bitcoin Universe product implements a trade path for it. Where a Universe indexer exists, the data is available through that indexer rather than through a product surface.
