Pack-level Provenance for Pharmaceuticals

Trace every custody hop with Hedera proofs & supOS live ops

Unify GS1-compliant labeling, Hedera Consensus Service notarisation, a supOS Unified Namespace, and Supabase-enforced access control so custody, telemetry, and operators stay in lockstep from manufacturing through dispense.

Features

Built for regulated custody chains

Each capability is wired to official specs so your compliance checklist, developer playbook, and on-site operations stay in sync.

Ledger-backed handovers
Append every custody event to Hedera Consensus Service with deterministic payload hashing and running hash validation.

GS1-compliant labels
Encode GTIN, lot, and expiry into a GS1 DataMatrix that scanners can read on web, PWA, or native wrappers.
View reference
Role-aware access
Supabase row-level security scopes data to the facility while auditors retain full read visibility across entities.

Backend
Supabase Postgres + Auth for OTP and password flows, typed route handlers, and storage-backed label assets.
View Reference
DLT layer
Hedera Consensus Service topics mirror every event with mirror node reads for auditors and patient verification.

User Flows

End-to-end flows

Day-one delivers the critical batch onboarding and custody chains; subsequent sprints extend scanning, verification, and reporting.

Step 1
Create batch
Manufacturers register GTIN, lot, expiry, and quantity, generate print-ready labels, and broadcast a MANUFACTURED event.
Step 2
Custody handover
Distributors scan the GS1 DataMatrix to validate provenance, then append RECEIVED and HANDOVER events with the next facility ID.
Step 3
Dispense & verify
Pharmacies issue receipts, patients confirm authenticity via public verify pages, and auditors export Hedera-backed PDF reports.
