- Serial
- Assay
- Custody
Who this is for
Refineries, assayers, vault operators, bullion dealers and compliance teams.
The operational challenge
A bar number alone does not show which sample was tested, which report applies or who accepted each handover. Teams spend days reconciling bar lists, assay certificates and delivery receipts.
An example workflow
- Step 01
Register the bar or lot with its serial number, declared weight and seal reference.
- Step 02
Attach the signed assay statement from the appointed laboratory.
- Step 03
Record each custody handover with weight and seal checks on receipt.
- Step 04
Share a verification view that shows issuer, status and history.
What the passport records
Serial number, declared weight, seal reference, assay version and every custody event, each signed by the accountable party and time-stamped in sequence.
Who verifies
The appointed assayer attests to the sample and method examined. Custodians confirm receipt conditions. Compliance teams review issuer authority and sourcing evidence before acceptance.
What stays private
Assay reports, photographs, prices, contracts and customer details remain in permissioned storage. Only the minimum verification data is shared, and nothing personal is written to a public ledger.
Exceptions handled clearly
A damaged seal, split lot or weight mismatch places the passport under review instead of showing a valid status. Re-assays and corrections keep the earlier version and the reason for change.

FAQ
Questions, answered
Does the passport prove a bar is genuine?
It proves who stated what, and when. Physical inspection and accredited assay remain the basis for authenticity and purity; the passport makes that evidence traceable and hard to dispute.
Can someone copy the passport code?
A code can be copied, so the passport is always checked against the physical serial, seal and custody record. A mismatch is flagged for review.
