Trace each component from Tier-2 to the finished vehicle on one shared consortium network. The Traceability Ledger and Device Attestation confirm authenticity at every tier, while the Quality and Recall Ledger isolates any defect down to the exact part lot.
Turn an opaque multi-tier supply chain into a single, tamper-evident record of authenticity.
01.
Replace blind faith in suppliers. The Traceability Ledger records every custody transfer from Tier-2 casting to Tier-1 assembly to OEM line, so no substitution slips in unseen between tiers.
02.
Bind identity to hardware. Device Attestation anchors a cryptographic signature from the factory press or laser marker to each part serial, making a cloned or grey-market unit fail verification instantly.
03.
Reject fakes at the bay. A technician scans a part before fitting it, and a component with no valid on-chain record returns a hard failure instead of a warranty landmine.
04.
Contain defects precisely. The Quality and Recall Ledger maps each serial back to its production lot, so a recall targets the exact affected batch rather than an entire part number.
05.
Enforce sourcing rules on-chain. When a counterfeit surfaces, its origin resolves to a specific vendor, who is flagged and removed from the approved list across every plant at once.
06.
Settle claims from proof. Each fitted part carries a verifiable authenticity record, so warranty disputes rest on cryptographic evidence rather than a contested paper invoice.
Follow a single brake component from its Tier-2 origin to the moment a technician verifies it at the service bay.

Cerulea decomposes parts provenance into modular contracts. Each layer mints, attests, transfers, and verifies a component without any single tier controlling the authenticity record.
Parts provenance is a horizontal capability. Here is how different actors across the automotive supply chain put the shared authenticity record to work.
Bind every verified component to a VIN on the line and remove counterfeit suppliers from the approved list the moment a fake is traced, cutting warranty exposure and field failures.
Key Asset Types
Attest each part at the press and co-sign custody upward, turning provable authenticity into a competitive advantage and a shield against substitution claims.
Key Asset Types
Scan replacement parts before fitting and reject any unit with no valid record, protecting technicians, drivers, and the dealer's warranty standing.
Key Asset Types
Whether you are bridging legacy MES and PLM systems from Tier-1 plants or capturing press signatures from Tier-2 devices, Cerulea routes both into one shared authenticity record.
For OEMs and Tier-1 suppliers on legacy MES and PLM. Existing production events are translated into signed on-chain part transitions through the API gateway automatically.

Building a multi-tier provenance network with device attestation, custody logic, and lot-level recall indexing from scratch requires specialised engineers and long supplier integration cycles. Calculate your exact deployment speed using Cerulea.

The legacy timeline reflects automotive supply-chain integration benchmarks. Wiring together each tier's MES, building custom attestation and custody logic, and shipping a lot-level recall index for an average network takes a baseline of 9 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your attestation and custody rules into pre-audited WebAssembly binaries and provisions the shared consortium ledger instantly.
