Coverage beyond the marketplace
The registry holds 38 protocols. Twenty-nine have a marketplace policy and appear in the support matrix. The other nine have none at all, and this page is where they live.
Two pages that answer different questions
Section titled “Two pages that answer different questions”The in-app /coverage page | The support matrix here | |
|---|---|---|
| Answers | What does this build read and serve? | What can Core do with it? |
| Generated from | The routing registry the running application uses | The marketplace registry the backend enforces |
| Rows | Every protocol with an index or a market route | The 29 with a marketplace policy |
| Good for | Finding a protocol’s index or market page | Deciding whether you can trade |
Read them together. Coverage tells you a page exists. The matrix tells you what the page will let you do when you get there.
What “covered” means
Section titled “What “covered” means”Covered means Core reads the protocol and serves it here.
It does not mean:
- that Universe operates the index behind that row. A row naming a read source is fetched by your browser straight from that host, and a read that does go through Core may itself come from an external provider;
- that a market has listings right now;
- that a market has depth or liquidity;
- that every action is available for that protocol.
A market with nothing listed says so. A market whose reader failed says that instead, and offers a retry. The two are never presented the same way, so an empty table is never a way of hiding an outage.
The nine with no marketplace
Section titled “The nine with no marketplace”These are read, explored, or inscribed. None of them can be listed, bought, or sold in Core, and there is no gate to open that would change that: the registry records no marketplace policy for them at all.

Three of those deserve a note.
- Atomicals appears here as the umbrella protocol, while its four tradable members (ARC-20, Atomicals NFTs, Realms, Subrealms) each have their own marketplace row in the matrix.
- Zerdinals and ZRunes settle on Zcash and are recorded with
readandexploreonly. Their own documentation is at docs-zerdinals-and-zrunes. - CAT-721 has no recorded inscribe or marketplace actions, in contrast with CAT-20 which has a testnet-gated trade preview.
Rows that name a read source
Section titled “Rows that name a read source”TAP, DMT, and UNAT carry a read source on the in-app coverage list, and the same sentence appears again on their index pages beside the numbers it applies to. Their deployment, mint progress, and holder figures are read by your browser from a host Universe does not operate, so their availability and freshness are that host’s rather than Core’s.
Every other row is read through the Core API. That API may in turn read an
external provider for a given protocol, which is what
/indexer-health reports per protocol.
