This record is generated from the Metal Stack item register and provides a tamper-evident log of the checks performed on this item. The record hash is SHA-256 over the verification facts and photograph fingerprints — any alteration to those changes the hash. Events are appended only; the register does not permit editing of past entries.
Metal Stack checks are non-destructive. They indicate that this item is consistent with the stated metal. Internal adulteration cannot be fully excluded without advanced testing. They are not a guarantee of authenticity, not a statement of legal fineness, and not a substitute for official hallmarking or assay-office certification. Under the Hallmarking Act 1973, legal fineness is determined only by a UK Assay Office hallmark.
Genuine Metal Stack records live only at metalstack.app. If a card or QR code sends you anywhere else, treat the item as unverified and report it.
Compare the item in hand against the photographs and the weight to 0.01 g. The tamper hologram must be intact — it shows a clear VOID pattern when lifted, so a damaged or missing hologram means the seal is void.
