Bind coal quality to payment on one shared network spanning miners, traders, ports, and utilities. Grade substitution becomes mathematically detectable and penalties execute from escrow the moment a calorific shortfall is proven, without arbitration.
Turn contested paper assays and delivery disputes into a single, quality-linked settlement record.
01.
Replace conflicting bills of lading. Miner, trader, port, and utility write each custody transfer to one Traceability Ledger, so a single record of tonnage and grade follows the cargo from pithead to boiler.
02.
Bind payment to assay. Escrow and conditional settlement release funds only against the delivered calorific value, so a lower grade than contracted triggers an automatic penalty rather than a negotiation.
03.
Make swapping stock detectable. Declared origin, grade, and mass are reconciled at each hop, so diluting a premium consignment with inferior coal breaks the record and is flagged before settlement.
04.
Seal the paperwork. The Trade Finance Documents module anchors letters of credit and invoices by digest, so financing banks release against verified custody instead of manually inspected scans.
05.
Capture the terminal. Gate-in, weighbridge, and customs clearance land on-chain as Port and Customs Events, giving every counterparty a live view of where a cargo sits and what it weighed.
06.
Settle from proof. When a utility contests quality, the ledger surfaces the co-signed assay and custody chain, so a dispute resolves against signed data in hours instead of weeks of correspondence.
Follow a single coal consignment from mine dispatch through the port to a utility that settles on verified calorific value.

Cerulea decomposes coal settlement into modular contracts. Each layer registers, transfers, assays, and settles a consignment so that quality and payment stay bound without any single trader controlling the record.
Quality-linked custody is a horizontal capability across bulk commodities. Here is how different actors in the coal chain put the shared ledger to work.
Settle fuel purchases on the calorific value actually delivered, deducting shortfall penalties from escrow automatically and cutting station heat-rate losses caused by undetected grade substitution.
Key Asset Types
Move consignments through ports with a co-signed custody trail, so financing banks release against verified tonnage and quality instead of manually inspected documents.
Key Asset Types
Read the consortium ledger to audit declared versus delivered grade across the corridor, replacing sample-based inspection with a live on-chain query over every shipment.
Key Asset Types
Whether you are bridging a utility's legacy fuel-management ERP or capturing weighbridge and assay data at the terminal, Cerulea routes both into one shared settlement record.
For utilities and large traders on legacy ERP. Existing dispatch and receipt events are translated into signed on-chain consignment transitions through the API gateway automatically.

Building a multi-party coal custody network with quality-linked escrow, assay oracles, and port event capture from scratch requires specialised engineers and long consortium integration cycles. Calculate your exact deployment speed using Cerulea.

The legacy timeline reflects bulk-commodity settlement integration benchmarks. Wiring together each counterparty's ERP, building custom quality-linked escrow and assay reconciliation logic, and capturing port and customs events for an average corridor 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 settlement rules into pre-audited WebAssembly binaries and provisions the shared consortium ledger and escrow layer instantly.
