Observatory · SEI (1329)
What the engine says it settled, against what the chain holds.
Two witnesses, asked on every render and compared: the venue's own engine, and the settlement contract on SEI read through a public RPC. A figure is corroborated when both agree, reported when one answers, and unavailable when neither does, with the reason written out.

Both witnesses answered and agree on 4 figures: what the engine says it settled is what the contract holds, and its signing key holds the role it claims.
- USDC held by the contract
- $26,717.04corroborated
- The USDC contract on SEI and the engine report the same balance for the settlement contract.
- Settled state root
- 0xdfb503df…0417a1corroborated
- The root the contract holds is the root the engine says it last submitted.
- Settlement sequence
- #343corroborated
- Contract and engine agree on the sequence. The engine is 10 ahead, with 10 operations pending settlement.
- Last settlement
- 739874.0 d agoreported
- 0001-01-01 00:00:00 UTC by the engine's clock; the engine's next submission window opens in 576714 s and it submits only when operations are pending. Not paused, not deferred.
- Engine signing key
- 0x67DF49c2…E2f534corroborated
- The engine names this key as its TEE signer, and the contract confirms it holds ROLLUP_MANAGER_ROLE, the role whose signatures move custody.
- Implementation behind the proxy
- 0x2071b624…badc59reported
- Read from the EIP-1967 implementation slot on SEI. A change here is an upgrade of the contract that holds custody.
- Total deposits, per the engine
- $26,717.04reported
- Lifetime deposits as the engine counts them. The chain figure above is what is held now; the two differ by withdrawals and settled P&L.
Read from the engine's configuration endpoint on this render (last changed 2026-09-06 11:03:35 UTC). These are reported: the engine is the only witness to its own rules, and an agent should read them from the same endpoint before it trusts them, not from this page. 718 markets are listed and 602 carry a configuration.
| Tier | Fee, bps | Funding spread, bps |
|---|---|---|

| 7 | 2 | 1 |
| 8 | 1 | 1 |
| 9 | 0 | 0 |
Whether a tier's figure is charged per side or per round trip is not stated by the endpoint; a cost model should assume per side until a fill says otherwise.
| Floor | Markets at this floor |
|---|---|
| $5 | 596 |
| $20 | 5 |
| $50 | 1 |
The floor is the smallest order the engine will take in a market. Most markets sit at the lowest floor; the majors sit higher.
- notarized
- We hold the transaction ourselves. Empty on this page until the desk has a fill of its own in the v2 book; it will not be filled by anything less.
- corroborated
- Two independent witnesses agree: the engine’s own API, and the settlement contract on SEI read through a public RPC.
- reported
- One witness says it, and the note names which. Where both answered and disagree, the figure shows the chain and the note says what the engine claimed.
- unavailable
- We do not have it. The note says why. This is a fact about the instruments this render, not a zero.
Engine and chain state only. No member, wallet or account data appears on this page, and none is queried to build it. The first cut of this page watched the v1 contract at 0xC6a7…3025; the venue moved to v2 on SEI and so did the page.
