01
A doctor issues
A verified doctor creates the prescription and sets exactly how many fills are allowed.
Prescription trust, built in
One prescription.
One token. One time.
Pacy connects doctors, patients, and pharmacies through a secure prescription record that cannot be forged, over-filled, or reused after expiry.

Anchored on Cardano
Fill count and validity are independently verifiable, while patient details remain private.
One trusted journey
Safer at every handoff.
Pacy makes the prescription lifecycle clear for everyone involved, without adding friction for the patient.
02
The patient carries
A rotating QR code gives the patient a simple, private way to share their prescription.
03
A pharmacy verifies
The pharmacy checks the live record and safely spends one fill when medicine is dispensed.
Private by design
Clinical details stay private. Trust goes on-chain.
Patient identity and medicine details stay off-chain. Only the proof needed to verify the prescription and its remaining fills is anchored to Cardano.
Built for confidence
One shared source of truth.
Every participant sees the same live prescription state, so the next decision is based on what is valid now—not a copy that may be out of date.
Tamper-resistant
A prescription cannot be quietly changed or duplicated.
Independently verifiable
On-chain activity creates a clear, auditable trust signal.
Privacy preserving
No patient or medication data is written to the blockchain.
