Hold direct, unencumbered legal title to fractional physical gold, and prove where it came from. Stannum binds every bar to its refiner record, carries the origin through every split, merge and resale, and issues certificates anyone can verify, without counterparty risk.
The source of truth already exists: accredited refiners record the bars they mint. Stannum binds to that record and carries the origin forward through every transfer, so the link to the mint is never lost, no matter how many times a holding is split, merged or sold. Fine weight is conserved at every step, and every certificate can be verified by anyone against a public record.
A new bar is bound to the refiner that minted it, the accredited record that says whether the bar is genuine. That binding becomes the root of its title.
Ownership moves in fractions between vetted parties. Fine weight is conserved, so totals always reconcile to the original bar.
Each holding carries a certificate anyone can verify against a public title record, without trusting Stannum. Identities stay sealed until disclosed.
Fine troy ounces, grams alongside.
Each origin gets a confidence tier from the strength of its evidence. A holding inherits the weakest tier of its roots, so a weak origin cannot be laundered clean by passing through many hands.
Checked live against the refiner’s own authoritative record. Provenance is verifiable to the mint.
Bound by hashed assay and acquisition documents from an accredited refiner. Strong, on documents rather than a live check.
Origin declared, with a named party publicly accountable for the claim. The market prices the difference honestly.
A 1 000 g bar is split and resold over time. Every transfer points back to its parents, the fine weight always reconciles, and the origin is never lost.
Stannum does not replace the existing bullion infrastructure. It sits on top of it and adds the public, owner-controlled, fractional chain of title the underlying systems do not provide.
The permissioned source ledger answers one question: is the gold real. Stannum answers the other: who owns which fraction, provably, and how well the origin was proven.
Owner-controlled certificates and the fractional chain of title, verifiable by anyone against a public record.
Confidence tiers computed from evidence; the weakest root governs a combined holding.
Each bar bound to the refiner’s authoritative record in the existing permissioned bullion infrastructure.
Built to sit alongside the Swiss bullion infrastructure the industry’s refiners and integrity bodies already trust.
