Anchor each panel bank's submitted rate and the resulting daily benchmark calculation as a verifiable, tamper-proof record. Anyone can confirm the benchmark was computed correctly and without manipulation, restoring trust after past rate-rigging scandals.
Turn an opaque, manipulable panel submission into a sealed, reproducible benchmark calculation.
01.
Anchor each input at source. The Oracle Feeds module records every panel bank's submitted rate with its signature, so no submission can be altered or backdated after the fact.
02.
Publish the method. The trimming and averaging logic runs on-chain, so the benchmark is reproducible from the same submissions by anyone.
03.
Seal each day's fix. The Audit Logs module writes the submissions and the resulting benchmark as an immutable record that cannot be quietly restated.
04.
Expose outliers. The Compliance Attestations module flags a submission that deviates abnormally from the panel, creating an evidence trail for the administrator.
05.
Let anyone check. A user recomputes the benchmark from the anchored submissions and confirms it matches the published fix.
06.
Open the archive. Every historical fix and its inputs are queryable, so the benchmark's integrity can be audited across time.
Follow a single day's benchmark from sealed panel submissions to an independently verifiable fix.

Cerulea decomposes benchmark integrity into modular contracts. Each layer seals submissions, computes the fix, anchors the day, and exposes the history so no one has to trust the administrator alone.
Verifiable benchmarks are a horizontal capability. Here is how different actors rely on a reproducible fix.
Publish a rate anyone can reproduce from sealed submissions, restoring confidence in a benchmark after past manipulation without exposing individual panel positions live.
Key Asset Types
Audit the fixing process directly and detect abnormal submissions early, replacing after-the-fact rate-rigging investigations with continuous verifiable evidence.
Key Asset Types
Reference a benchmark whose integrity is provable, giving borrowers and counterparties confidence in the rate their contracts reset against.
Key Asset Types
Whether you are collecting submissions from panel bank systems or serving verifiers publicly, Cerulea routes both into one sealed benchmark record.
For panel banks on legacy submission systems. Rate submissions are translated into sealed on-chain records through the API gateway automatically.

Sealed Fixing Record
Building a benchmark integrity system with sealed submissions, an on-chain fixing calculation, immutable seals, and a public verification archive from scratch requires market data engineers and long panel integration. Calculate your exact deployment speed using Cerulea.

The legacy timeline reflects benchmark administration integration benchmarks. Wiring sealed panel submissions, an auditable trimmed-mean calculation, tamper-evident seals, and a public verification archive takes a baseline of 7 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your submission and fixing rules into pre-audited WebAssembly binaries and provisions the benchmark ledger and verification archive instantly.
