A read-only forensics indexer over the venue’s on-chain attested event stream: every account, order, fill, itemized fee, funding payment and liquidation, reconstructed without touching the venue API. The honest institutional pitch is the audit trail, and this is it, queryable.
§1Capabilities
Rebuilds venue history from attested on-chain events: per-fill fee decomposition, the complete liquidation family, session-key registrations with expiries.
Closes the accounting identity: total deposits minus withdrawals against live custody, at any block height. When that invariant holds, the whole pipeline is validated; when it breaks, you want to know first.
Measures execution friction from chain data (fee-over-notional distributions by symbol, size and time), turning venue-quality claims into measured, citable numbers.
§2Design
Two witnesses by design. The public page asks the venue’s engine and the settlement contract on SEI the same questions on every render and grades each figure by whether they agree. The forensics indexer on the roadmap adds the third witness, our own held transactions.
Append-only, re-decodable. Raw logs are stored immutably and decoded separately, so when the venue updates its event schemas, history is re-interpreted, never lost.
Drift-aware. The venue publishes config and schema hashes on-chain; the Observatory listens, freezes decoding on change, and alerts the operator.
§3Availability by tier
| Open | Public venue state at /observatory: custody, settled root and sequence, the engine’s signing key and its role, the fee ladder, live now. |
| Pro | Query access and entity-table exports. |
| Institutional | Full dataset feeds and custom analytics. |
Indicative until launch.
§4 · Stated plainly
The forensics indexer is in development against a published roadmap. What is live checks the engine’s claims against the chain, including whether its signing key holds the role that moves custody; it does not make claims about the trust model beyond what that check shows. The audit value is the notarised record of every action and fee, not trust-minimisation, and we say so.
