Indexer

Primary index

Configured Atomicals ElectrumX/Atomicals Marketplace authority

Fallbacks

None. If the primary index cannot be read, this protocol has nothing to fall back to and the page says the read failed.

What a mutation must prove

Mutations fail closed on mixed collateral, wrong NFT subtype, spent outpoint, checkpoint drift, burn, or ownership mismatch.

Freshness, confirmation, and reorg policy

Policy	Value	What the registry states
Freshness enforced	No	Every mutation rechecks the Bitcoin and Atomicals checkpoint; deployment readiness must enforce operator lag limits.
Maximum index lag	not set	No numeric block-lag ceiling is configured for this protocol.
Maximum observation age	not set	No maximum age is configured for an observation used by a mutation.
Listing confirmations	not set	Settlement requires at least one confirmation by default; operators may configure 1-100.
Settlement confirmations	1	A trade is recorded as settled after 1 confirmation.
Automatic reorg reconciliation	Yes	The Atomicals journal retains signed listing proof and converges sold rows through authoritative outspend reconciliation.

Where else this protocol appears

The Bitcoin Universe registry records actions per product surface. Core is the main surface. The others are named here because a reader who cannot do something in Core may be able to do it in a sibling product.
