Read the support matrix
Twenty-nine protocols, thirteen marketplace actions, and the registry’s own reason for every action that is not available. This is the page to read before you assume you can trade something.
Core
One explorer, portfolio, and market for the Bitcoin and Dogecoin metaprotocols. Every figure on screen can be traced to the reader it came from, and a reading that failed says so instead of showing a zero.
What Core is
Section titled “What Core is”Core is the Bitcoin Universe application at www.bitcoinuniverse.io. It is four things in one place:
- an explorer for Bitcoin and Dogecoin blocks, transactions, addresses, and outputs, and for the metaprotocol assets carried on them;
- a portfolio that groups what an address holds by chain, protocol, and asset type;
- an activity record of what has traded and what has moved;
- a marketplace for the protocols whose execution path is complete.
It is for people who read chain data: collectors checking what they own, buyers checking a listing before they sign, and developers checking what an index actually returned. It is non-custodial. Keys stay in the reader’s own wallet, and no action moves an asset without a signature approved there.

Where to start
Section titled “Where to start”Learn to read the states
Unknown is not zero. Empty is not unavailable. Core shows those four things differently on purpose, and reading them wrongly is the fastest way to make a bad decision.
Check where a number came from
Every figure has a reader behind it. Some readers are Universe-operated, some are external providers, and three protocols are fetched by your own browser from a host Universe does not run.
Trade safely
What to check before you sign, what a fail-closed gate means, and why an unavailable action is a safety decision rather than proof that a market is empty.
Call the public API
An OpenAPI 3.1 document covering the public read endpoints, including the health and per-protocol freshness contracts.
Fix something that looks wrong
A market that says unavailable, a wallet that will not connect, a figure shown as a dash. What each one means and what to do next.
Chains and networks
Section titled “Chains and networks”| Chain | Networks Core serves | Protocols in the registry |
|---|---|---|
| Bitcoin | mainnet | 33 |
| Dogecoin | mainnet | 3 |
| Zcash | mainnet | 2, read and explore only |
A staging deployment exists for validation. It uses its own isolated API lane and never falls back to production data. It is not a place to move real funds.
Lifecycle and release
Section titled “Lifecycle and release”Core is a running production application. It does not publish a semantic
version string: its release identifier is the exact commit the deployment was
built from, and the public health response returns it in the release field.
That is the only release number this documentation will quote, because it is
the only one the product actually states.
This documentation site is versioned with the product it describes and is
marked experimental in its
manifest
for exactly that reason: there is no tagged Core release to point a
releaseVersion at, and inventing one would be worse than admitting it.
The rest of Bitcoin Universe
Section titled “The rest of Bitcoin Universe”Core is one product in a wider set. The portal at docs.bitcoinuniverse.io is the entry point for all of them, including Wallet, Inscribe, and StampDEX, which appear in the protocol registry as sibling surfaces alongside Core.
