Crude Provenance Engine

Verify origin and grade.
Settle on delivery proof.

Deliver a crude oil provenance network where origin and quality are verified at each custody transfer, payment is conditional on delivery confirmation, and sanctions compliance documentation is immutable. A refinery sanctions audit for a year of purchases completes in a day using on-chain origin records.

The Foundation

The Execution Mechanics

Turn falsifiable paper documentation into a verified, sanctions-ready chain of crude custody.

01.

Custody Chain Tracking

The Traceability Ledger records each transfer of crude from well to refinery, so origin and grade travel with the cargo instead of on falsifiable paper.

02.

Verified Grade & Origin

Each custody transfer confirms crude grade and origin, making the mislabelling that price differentials incentivize detectable at every hop.

03.

Conditional Payment

Trade Finance Documents and conditional settlement release payment only on delivery confirmation, protecting buyers against undelivered or misrepresented cargo.

04.

Immutable Sanctions Record

Origin attestations are sealed on-chain, giving a refinery immutable documentation of crude provenance for sanctions compliance.

05.

Port & Customs Events

The Port and Customs Events module anchors loading, discharge, and clearance events, tying the physical movement of crude to its documented custody.

06.

Rapid Compliance Audit

A compliance team queries a year of origin records in a day, replacing weeks of document retrieval for sanctions exposure reviews.

The Crude Provenance Lifecycle

Follow a single crude cargo from wellhead through custody transfers to a refinery sanctions audit.

Smart Contract Anatomy

Cerulea decomposes crude provenance into modular contracts. Each layer anchors origin, transfers custody, ties payment to delivery, and exposes sanctions-ready records.

Applicability Across the Spectrum

Crude provenance tracking is a horizontal capability. Here is how different actors in the oil supply chain put the shared ledger to work.

Refiners & Buyers

Verify crude grade and origin at every hop and clear sanctions audits in a day, protecting against mislabelling and undelivered cargo with an immutable record.

Network & Execution Architecture

Whether you are bridging trading and terminal systems or capturing custody at port from a field device, Cerulea routes both into one provenance ledger.

Track A: Trading System Bridging

For traders and terminals on legacy systems. Custody and document events are translated into signed on-chain records through the API gateway.

Technical Methodology

The legacy timeline reflects commodity trade integration benchmarks. Wiring trading and terminal systems, building custom custody and conditional payment logic, and shipping sanctions tooling for an average trade flow takes a baseline of 9 months. Building the same architecture on Cerulea takes a baseline of 2 weeks, because Cerulea Studio visually translates your custody and compliance rules into pre-audited WebAssembly binaries and provisions the provenance ledger instantly.
