Run a private project materials chain that binds each batch to its origin and lab test results before it reaches the site. Delivery approval and supplier payment are gated on a passing quality certificate, so substandard material under a falsified document never gets installed.
Turn falsifiable paper certificates into batch provenance with payment-gated quality approval.
01.
The Traceability Ledger records each material batch from its source plant, so a delivery maps to a verifiable origin instead of an unverifiable challan.
02.
The Quality and Recall Ledger binds independent lab test results to the batch, making a passing grade a signed on-chain fact rather than a printed sheet.
03.
Mill certificates and test reports are anchored by digest, so any tampering with a quality document breaks its hash and is instantly detectable.
04.
The contract approves site delivery and releases supplier payment only when a passing certificate exists, keeping unverified batches out and disputes to zero.
05.
If a later test fails, the ledger isolates the exact batch and every location it was installed, triggering a targeted recall instead of a site-wide stop.
06.
Pass and fail rates accumulate against each supplier, giving the developer an evidence-based basis for approving vendors on future packages.
Follow one material batch from source registration through lab certification to payment-gated delivery.

Cerulea decomposes materials certification into modular contracts. Each layer origins the batch, certifies quality, gates delivery, and releases payment without any supplier able to pass off an unverified batch.
Payment-gated materials provenance is a horizontal capability. Here is how different construction actors put the batch chain to work.
Guarantee no unverified batch is installed by gating delivery and payment on lab certification, and target recalls to a single batch instead of stopping the whole site.
Key Asset Types
Get paid faster on verified batches and build an on-chain quality track record that wins future packages, replacing disputes over rejected loads with clean settlement.
Key Asset Types
Sign test results directly to the batch, turning a printed report that can be forged into a tamper-evident certificate the whole project relies on.
Key Asset Types
Whether you are bridging supplier ERP and lab systems or capturing deliveries from a site gate scanner, Cerulea routes both into one materials provenance record.
For suppliers and labs on established systems. Batch and test data translate into anchored on-chain provenance and quality records through the API gateway automatically.

The legacy timeline reflects supply-chain integration benchmarks. Wiring supplier and lab systems, building payment-gated delivery, and shipping automated recall for an average project takes a baseline of 8 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your provenance and quality rules into pre-audited WebAssembly binaries and provisions the traceability and recall layers instantly.
