Record the handover date and every warranty claim in one shared ledger, so disputes about whether a defect falls inside the liability period are settled instantly. Homeowner and builder both see, at a glance, whether a reported issue is still covered.
Turn a contested handover date and scattered claim history into one shared, timestamped warranty record.
01.
The Provenance Notary seals the handover date and defect liability period for each unit, so the clock on coverage starts from an agreed, immutable point.
02.
Each warranty claim is recorded with its date against the unit, building a complete history instead of scattered emails and site visit notes.
03.
The Compliance Attestations module compares a claim date against the liability window automatically, returning covered or lapsed without argument.
04.
The Audit Logs module records every claim, response, and resolution, giving both parties a tamper-evident trail of how each issue was handled.
05.
A claim's status moves from raised to acknowledged to resolved on-chain, so neither party can later dispute whether a defect was actually fixed.
06.
Homeowner and builder read the same record, replacing conflicting private accounts of the handover date and claim history with one source of truth.
Follow one unit from handover through a warranty claim to an instant coverage determination.

Cerulea decomposes warranty tracking into modular contracts. Each layer anchors the handover, records claims, determines coverage, and logs resolution without either party rewriting the timeline.
Shared warranty tracking is a horizontal capability. Here is how different post-handover actors put the coverage record to work.
See the sealed handover date and their full claim history, getting an instant, non-negotiable answer on whether a defect is still within the liability period.
Key Asset Types
Defend against out-of-period claims with an immutable handover date and manage warranty obligations across a portfolio from one status ledger.
Key Asset Types
Track defect claims and resolutions for handed-over units on behalf of residents, coordinating fixes against a shared, evidenced record.
Key Asset Types
Whether you are bridging a developer's CRM and helpdesk or capturing claims from a resident app, Cerulea routes both into one warranty record.
For developers on CRM and helpdesk systems. Handover and ticket data translate into anchored on-chain warranty records through the API gateway automatically.

The legacy timeline reflects proptech integration benchmarks. Wiring CRM and helpdesk systems, building coverage determination, and shipping a shared claim history for an average portfolio takes a baseline of 7 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your handover and claim rules into pre-audited WebAssembly binaries and provisions the notary and audit layers instantly.
