Anchor custodian confirmations of foreign exchange reserve holdings as verifiable records at regular intervals. The central bank gains a stronger evidentiary basis for its public reserve disclosures than internal reconciliation with custodian banks abroad.
Turn internal reconciliation with foreign custodians into a signed, verifiable attestation chain.
01.
Anchor holdings at source. The Provenance Notary module records each custodian's signed confirmation of the reserves it holds, so a disclosure rests on custodian evidence rather than internal books.
02.
Fix each reporting date. Reserve holdings are attested at regular intervals, producing a consistent record aligned to the transparency reporting cycle.
03.
Verify the mix, not just the total. Each attestation records the currency and instrument composition, so the disclosed reserve breakdown is independently supported.
04.
Prevent silent revision. The Audit Logs module seals each custodian confirmation, so a past attestation cannot be quietly changed before a disclosure.
05.
Replace manual matching. The system reconciles custodian attestations against the central bank's internal record automatically and highlights any mismatch.
06.
Back the public number. The Compliance Attestations module compiles the attested holdings into evidence the central bank can reference in its transparency disclosure.
Follow a single reporting period from custodian confirmation to disclosure-ready evidence.

Cerulea decomposes reserve attestation into modular contracts. Each layer confirms holdings, records composition, reconciles, and compiles evidence without relying on internal books alone.
Reserve attestation is a horizontal capability. Here is how different actors rely on verifiable custodian confirmations.
Back public reserve disclosures with anchored custodian confirmations, replacing internal reconciliation with a verifiable evidentiary basis that strengthens market credibility.
Key Asset Types
Provide signed confirmations of the reserves they hold, giving the central bank a direct verifiable attestation instead of periodic statements.
Key Asset Types
Reference an attested reserve position when assessing sovereign strength, using verifiable evidence rather than an unaudited public figure.
Key Asset Types
Whether you are collecting confirmations from custodian systems abroad or serving the central bank's reporting desk, Cerulea routes both into one attested reserve record.
For custodian banks on legacy systems. Holdings confirmations are translated into signed on-chain attestations through the API gateway automatically.

Building a reserve attestation system with custodian confirmations, composition records, automatic reconciliation, and disclosure evidence from scratch requires reserve management engineers and long custodian integration. Calculate your exact deployment speed using Cerulea.

The legacy timeline reflects reserve management integration benchmarks. Wiring custodian confirmations, composition recording, automatic reconciliation, and a disclosure evidence compiler for an average central bank takes a baseline of 8 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your attestation and reconciliation rules into pre-audited WebAssembly binaries and provisions the reserve attestation ledger and evidence compiler instantly.
