Products & Services — Software
Purpose-built for the chain's checkpoints
Not one monolithic platform — three focused tools, each built for a specific actor at a specific point in the chain of custody, each designed to produce the records the frameworks require.
AssayCert Generator
QR digital receipts for every assay
The metals chain assays a consignment three times — at origin, pre-export, and pre-refinery — and each certificate must stand on its own. AssayCert Generator issues each assay as a digital receipt with a scannable QR code, so any downstream buyer, auditor, or border official can verify purity, weight, batch, and the certifying lab in seconds.
- One QR-coded digital receipt per assay, tied to the consignment
- Purity, weight, batch ID, and lab credentials in every certificate
- Verification page for anyone who scans — no account required
- Certificate history per lab, ready for traceability audits
Ledger Lite
Mobile KYC and purchase logs for field buying
OECD due diligence starts with knowing your counterparty and documenting every transaction — hard to do in a notebook at a buying station. Ledger Lite is a mobile-first log for field buyers: capture counterparty identity, record each purchase with weight and price, and build the management-system records that CRAFT Module 1 and any downstream audit will ask for.
- Counterparty KYC records with photos and license references
- Timestamped purchase logs — weight, price, origin claim
- Works offline in the field, syncs when connected
- Export-ready records for buyers and auditors
Batch Weaver
Mass-balance software for consolidated consignments
When an aggregator melts and combines material from many sources into one consignment, provenance survives only if inputs reconcile with outputs. Batch Weaver maintains the mass-balance: every input batch with its assay and origin, every output consignment with its composition — exactly what a traceability verification audit needs to see before export.
- Input batches linked to origin assays and Nelum IDs
- Output consignments with full composition breakdowns
- Automatic reconciliation flags for unexplained variances
- Audit-ready mass-balance reports per consignment
