Anchor the portfolio valuation inputs and the resulting daily NAV as a verifiable record every trading day. Unit holders and auditors independently confirm the published NAV was calculated correctly from the fund's real holdings and market prices.
Turn an unverifiable daily number into a reproducible, independently checkable calculation.
01.
Anchor the inputs. The Oracle Feeds module records each underlying holding and its market price for the valuation cutoff, so the NAV rests on verified data rather than an internal spreadsheet.
02.
Publish the method, not just the answer. The calculation logic runs on-chain, so anyone can reproduce the per-unit NAV from the same priced holdings.
03.
Seal each day. The Audit Logs module writes the priced holdings, fee deductions, and final NAV as an immutable daily record that cannot be quietly restated later.
04.
Let holders check the math. A unit holder or auditor recomputes the NAV from the anchored inputs and confirms it matches the number the fund published.
05.
Expose the series. The Subgraph Indexer module makes every past daily NAV and its inputs queryable, so a holder can audit the full history in one query.
06.
Catch restatements. If a published NAV diverges from the reproducible calculation, the record flags it immediately for the fund and its auditor.
Follow a single trading day from price ingestion to a NAV a unit holder can independently verify.

Cerulea decomposes NAV transparency into modular contracts. Each layer ingests prices, calculates, seals the day, and exposes the series so no unit holder has to trust an unverifiable number.
Verifiable NAV is a horizontal capability. Here is how different actors rely on a reproducible daily valuation.
Publish a NAV that unit holders can independently reproduce, turning a point of suspicion into a trust signal without exposing proprietary trades intraday.
Key Asset Types
Verify a fund's NAV history directly from anchored inputs instead of requesting spreadsheets, compressing valuation audits into a live query.
Key Asset Types
Show investors a NAV backed by a verifiable record, differentiating the funds they distribute on transparency rather than marketing claims.
Key Asset Types
Whether you are bridging a legacy fund accounting engine or feeding prices from a market data vendor, Cerulea routes both into one verifiable valuation record.
For asset managers on legacy accounting platforms. Holdings and fee data are translated into signed on-chain valuation records through the API gateway automatically.

Building a verifiable NAV system with anchored price inputs, an on-chain calculation, immutable daily seals, and a public history index from scratch requires fund technology engineers and long audit integration. Calculate your exact deployment speed using Cerulea.

The legacy timeline reflects fund accounting and audit integration benchmarks. Wiring priced holdings, an auditable NAV calculation, tamper-evident daily seals, and a holder verification portal for an average fund takes a baseline of 7 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your valuation and audit rules into pre-audited WebAssembly binaries and provisions the anchored NAV ledger and history index instantly.
