The hardware · Gold Shield Unit
A gold laboratory, sealed in your vault.
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 built to install inside the vault you already have — the way a smart camera turns an ordinary door into a monitored one. Once mounted, it's built to run 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. No human touches the numbers, and the gold never leaves your custody. We don't sell vaults — we make yours tell the truth.
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 instrument · three configurations · installs into the vault you already have
Field unitconfigured for an aggregator's buying-counter vault — verification at the mine-site point of trade
Processing unitconfigured for refinery and assay-office vaults — purity certification for export
Institutional unitconfigured for a bank or reserve's vault room — sovereign-grade verification where the gold already sits
We don't sell vaults. Our GSU is the instrument inside yours — the same core (XRF sensor, precision scale, secure element, GPS, cellular) configured for wherever your gold is already held, turning that custody into proof anyone can recompute. The GSU is at bench-prototype stage today; the vault-install production unit is pre-production, targeted Q3 2026 — while the attestation pipeline it feeds runs live now.
What is VPAY Genesis · the invention
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.
How the seal works
From a lump of gold to a claim anyone can check.
Four steps, a few seconds, at the point of trade — no lab, no middleman, no trust required.
1
Place the goldThe operator sets the gold in the GSU's shielded drawer, inside the vault. The sensor reads the metal's physical signature.
2
Stamp & sealLocation and a secure timestamp are added, then the whole reading is sealed inside a hardware chip.
3
Anchor on-chainThe sealed fingerprint is written to Polygon — permanent, time-stamped, and impossible to quietly change.

The moment · Ghana → the world
Ghana's gold just crossed a historic line — and the whole market now asks for proof.
Small-scale mining now produces the majority of the country's gold, and the rules for proving where it came from are changing fast. It isn't only GoldBod asking — ministries, the central bank, environmental regulators and the global bullion market all now demand the same thing: proof of origin.
0%
of Ghana's 2025 gold output came from small-scale mines — overtaking industrial mines for the first time in over a century.

These are the authorities, standards bodies and buyers a gram of gold must now answer to. VPAY exists so the answer is a proof anyone can recompute — not a promise on paper.
Where did this gold come from — and can I prove it?
Our strongest edge · Compliance in a box
The layer a regulator needs to actually enforce.
Every enforcement regime can only police what someone can prove. VPAY is that proof — and the compliance program around it is owned in-house, not bolted on.
CCO-owned AML / KYC
Our Chief Compliance Officer owns the anti-money-laundering and customer-verification program end to end — Know Your Customer and Know Your Business, per-operator and per-jurisdiction risk scoring — with an independent reporting line to the board.
Built to Ghana's statutes
Designed around the Minerals and Mining Act 2006 (Act 703, Art. 114) and the Ghana Gold Board Act 2025 (Act 1140) — the laws GoldBod enforces — so the proof maps to the rules, not around them.
Enforcement, made possible
The bodies that police responsible sourcing can only act on evidence. VPAY gives them evidence anyone can recompute — open, timestamped and tamper-proof on a public chain.
The regimes that demand verifiable proof
EcoVent's compliance posture is owned by our Chief Compliance Officer and built to the statutes above. It does not, on its own, make EcoVent a licensed or regulated financial institution — it makes the proof we produce something a regulator, refiner or buyer can rely on.

The capital layer · $SOV + vault
Proof that unlocks capital — in real time.
Slow payment is the black market's best friend. When a licensed seller waits days for the banking system, the smuggler's instant cash wins — and the gold leaves through the back door. VPAY closes that gap: gold sealed by the GSU can mint $SOV — a token the contract refuses to mint without a sealed physical reading — and that verified gold can back on-chain credit the moment it's proven. Legal gold gets paid like the black market pays: now.

GoldBod mandate · live now
Every licensed gold buyer must report each sale within 5 minutes — and today, that means a phone call or text message to their aggregator.
Complying by text or call
A person reads a weight and price and relays it from memory, mid-transaction. Slow, approximate, and easy to dispute — the exact gap the black market lives in.
Complying with our GSU
Our GSU seals every sale the instant gold changes hands — weight to a hundredth of a gram, purity, time and place, tamper-proof and on-chain. The 5-minute record is made automatically. Nothing typed, nothing to dispute — and you keep the licence you trade on.

The Company
EcoVent
EcoVent
Africa.
The world runs on claims about physical things — this gold is real, this crop is clean, this decision was made — and almost none can be independently proven. We build the infrastructure that makes them provable.
From Accra, we design and build the full stack ourselves: the Gold Shield Unit that reads and seals an asset at the source, the smart contracts that anchor every reading on the Polygon public blockchain, and the open verification pages where a regulator, a bank or a buyer can recompute the proof without asking our permission.
Gold is our first front, built for Ghana's GoldBod mandate. The same engine extends to crops under the EU Deforestation Regulation and to AI accountability under the EU AI Act — three markets where proof is becoming law.

Where we are — honestly
We'd rather be trusted than hyped.
VPAY Genesis is pre-revenue. The trading and intelligence engines run on paper, not live capital. Our smart contracts are source-verified on Polygonscan but not yet independently audited.
$SOV is minted only against a confirmed, physically-attested gold reading — never against an unverified claim. Carbon, land and the other verticals are early-stage services on the same rail; they do not back the token.
If it isn't verifiable, we don't claim it. That's the whole point.
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.
