Other protocols

Protocols that do not sit in one of the larger families.

Deploy, mint and transfer, with one idea at its centre: the mint output satoshi value encodes the amount. The value of the output is not padding, it is data.

That makes the output size a protocol matter rather than a preference, so do not treat the 546 and 330 satoshi choices here the way you would on an ordinary inscription.

Workspace: /dust20. Released.

Inscribe only. A shared world grown one contribution at a time, where each contribution is an inscription.

ChainBloom is one of the flows that chooses funding outputs on your behalf, so its fee inputs pass through the asset screening described in asset safety.

Workspace: /chainbloom. Released, and a deployment must switch it on.

Not released. The production contract classifies CAT-20 as incomplete, and this is the one entry on the page where that has visible consequences you should plan around.

CAT-20 transaction features stay fail-closed when the required Fractal data and signing dependencies are unavailable. Market discovery reports that dependency state directly rather than returning an empty market that would look like an answer.

The workspace explores CAT-20 on Fractal, checks balances and prepares covenant mints, and you pick the network yourself. Treat all of it as unfinished.

Workspace: /cat20. Not released.

Four more workspaces exist in the app and are classified as incomplete by the production contract. They are listed here so their absence from the rest of this site is a stated decision rather than an oversight:

WorkspaceWhat it is meant to become
Witness CirclesTaproot outputs a group authorises together
TandemBuilding and changing one object together, with a signed record of each change
PatinaHow long a value-carrying output has stayed where it is
Drop PactsDesigning and launching Drop Pact agreements, with a resumable tutorial

None of these are documented on this site as things you can rely on. Tandem does have one effect worth knowing even so: Tandem state carriers cannot fund ordinary sends, mints, replacements or recovery plans at all, which is a firmer restriction than the usual asset screening applies.
