The medicine
proves itself.
Across parts of Africa, a large share of medicine in circulation is falsified or substandard. A patient cannot tell a real pack from a fake β until it fails to heal. VPAY gives every pack a scan-to-verify chain of custody, sealed at manufacture and recomputable before the pill is ever swallowed.
Aduru di adanseΙ β the remedy bears witness.
A fake pack looks
exactly like the real one.
Counterfeit and substandard medicine kills β and the patient has no instrument to tell the difference at the point of sale. Holograms get copied. Batch numbers get reused. The trust gap is fatal.
Substandard or falsified
An estimated share of medicines in low- and middle-income countries fails the patient.
Holograms aren't proof
The anti-counterfeit measures on the box are themselves counterfeited at scale.
It fails when it matters
The fake is discovered when the fever doesn't break β when verification is impossible.
One scan, before you swallow it.
The pack carries its own proof
At manufacture, each pack's identity is sealed and anchored on a public chain. A pharmacist or patient scans it β the phone recomputes the seal and checks it against the anchor. A real pack resolves instantly. A fake one cannot: there is no anchor to match, and the contradiction is plain. No central server to trust, no hologram to copy.
Illustrative. The WHO figure is a global estimate, not a Ghana-specific claim.
From the factory line to the patient's hand.
Four steps, no trusted middleman. Steps 3 and 4 run live on Polygon today β the same engine VPAY runs for gold.
Sealed at manufacture
Each pack's identity and batch are hashed and signed on the production line.
Anchored publicly
The seal is written to a public blockchain β permanent, tamper-evident, ownerless.
Scanned in the field
A pharmacist or patient scans the pack with any phone β no app login, no account.
Recomputed instantly
The phone recomputes the seal and matches it to the anchor. Real resolves; fake can't.
The engine is live.
The first line is next.
Manufacturers, regulators, pharmacy chains β
let's make every pack provable.
The engine is built and live. The next step is a supervised pilot sealing one product line, with a manufacturer and regulator at the table.
