Our GSU reads the asset itself
A lab-grade instrument — XRF assay, precision scale and GPS in one sealed unit, designed to mount inside the vault. The gold comes to the sensor in a shielded drawer; it measures the metal, not a form.

The Gold Shield Unit · GSU-1
Weigh it. Assay it. Seal it. In 200 milliseconds.
The GSU is a standalone instrument that sits at your buying counter. A lot goes into its shielded drawer for a few seconds, and comes straight back out. It reads the metal's true purity, weighs it to a hundredth of a gram, stamps where and when, and writes a sealed record to a public ledger — before any person can type a number. Your counterparty, your bank and your regulator all check the same record, and none of them has to trust you.

1The instrument
The assay lab comes to the gold, not the other way round.
GSU hardware · bench-prototype stage · production targeted Q3 2026. The on-chain proof layer is live & verifiable today.
Most gold verification is a person with a handheld scanner and a form to fill in. Our GSU is different by design: a lab-grade instrument that sits at the counter, where the gold is traded. You place a lot in its shielded drawer and it runs the full laboratory test in 200 milliseconds: read the metal, weigh it, stamp where and when, and write the proof straight to the public ledger — then the gold comes straight back out. No human touches the numbers, and we never take custody of your gold. We don't buy your gold — we prove it.
INTAKE
Shielded drawer
The gold goes into a lead-lined drawer at a fixed distance from the sensor — safe for the operator, exact for the physics. The gold comes to the sensor, never the other way round.
READ
XRF assay + precision scale
X-ray fluorescence reads the metal's true composition and purity — a physical fingerprint a forgery can't reproduce — while a built-in scale weighs it. Seconds, not days at a lab.
STAMP
Multi-GNSS + secure clock
Adds exactly where and when the reading happened, from a source that can't be back-dated.
SEAL
Hardware secure element
Locks the whole reading inside a tamper-resistant chip the instant it's taken. It can't be quietly edited later.
SEND
Cellular uplink → Polygon
Writes the sealed fingerprint to a public blockchain — and the gold stays inside the vault, verified and in custody, in the same place.
Component names are capability-level; detailed hardware spec available under NDA.
One core · three configurations · from the buying counter to the bank vault
Field unita counter-top unit for an aggregator's buying point — verification at the point of trade
Processing unitfor a refinery or assay office — purity certification for export
Institutional unita wall-mounted module for a bank or reserve vault — sovereign-grade verification
One instrument, configured for where your gold is traded — the same core (XRF sensor, precision scale, secure element, GPS, cellular) scaling from a counter-top field unit to a wall-mounted bank-vault module, turning the moment of trade into proof anyone can recompute. It never takes custody of your gold. The GSU is at bench-prototype stage today; the production unit is pre-production, targeted Q3 2026 — while the attestation pipeline it feeds runs live now.
2Why it can't be fooled
Not just a scanner. The Physics Gate.
VPAY Genesis proves a physical asset is real at the point of trade. At its heart is our Gold Shield Unit (GSU) — and the invention inside it, the Physics Gate: eight independent physical and cryptographic checks that must all agree in one sealed reading before anything is recorded, then anchored on a public blockchain anyone can recompute. Not a certificate. Not a database — a seal you can recompute.
The question every buyer asks
"Can our GSU be fooled into sealing a rock — or brass — as gold?"
No — and that is the whole invention. One measurement can be tricked; eight that must agree cannot. The Physics Gate reads the metal's atomic X-ray signature — only real gold emits it, so gold-plated tungsten, brass or a painted rock fail on the spectrum instantly. In the same 200-millisecond window it cross-checks the mass and density, the GPS location, a live tamper seal and more. Miss a single gate and the contract refuses to mint. You can forge paper — you cannot forge physics.

02 · Seal
It locks the reading
The instant the Physics Gate passes, the reading is signed inside a hardware secure element — tamper-evident, and impossible to quietly edit.
03 · Anchor
Anyone can recompute it
The sealed proof is anchored on Polygon — permanent and public. A buyer, auditor or regulator re-runs the math. The proof is the math, not our word.
Three fronts, one engine
Focused where the law now demands proof.
The same seal → anchor → recompute engine, pointed at three markets where verification is becoming mandatory and enforcement is already underway.
GOLD · BACKS $SOV
Prove origin
Ghana's GoldBod track-and-trace mandate, under the Gold Board Act, 2025 (Act 1140). Our flagship — live today.
CROPS
Prove it's clean
The EU Deforestation Regulation (EUDR) requires proof that cocoa and other exports are deforestation-free — no proof, no EU market.
AI & AGENTS
Prove accountability
As AI rules like the EU AI Act phase into force, every automated decision needs an owner — bonded, challengeable, anchored on-chain.
Engagement
In the room with the right people.
Verification only counts if the people who move the gold, fund it and regulate it are in the conversation. Alongside our partners above, we're in active engagement across the sector.
In active conversation with
Development finance & banks
Government regulators
Licensed aggregators & buyers
Ghanaian mining operators
Refiners & exporters
Industry associations
Exploratory conversations across the sector — capital, regulation and the trade itself — to make sure VPAY Genesis meets the standard each of them holds. Early-stage engagement, not partnerships or endorsements.

No verification, no trust · no token
Make your gold provable.
Whether you hold a GoldBod licence, regulate the sector, or buy the gold — let's make origin something you can prove, not just promise.
