Pharmaceutical cargo worth billions spoils or gets disputed every year — because cold chain records can be altered, backdated, and challenged. April Gate makes tampering cryptographically impossible. Not just hard. Impossible.
When a pharmaceutical cold chain dispute arises today, there is no immutable record. Centralized logs live on servers controlled by one party. Sensor data can be backdated. Liability arguments drag on for months — and someone always loses money they shouldn't have.
Insurers pay disputed claims they can't disprove. Distributors absorb losses for excursions they didn't cause. Pharma companies discard product they can't prove was compromised. The entire system runs on trust that has no mathematical foundation.
April Gate changes the trust model at the root. Not just better logging. Cryptographically provable truth.
Each sensor is backed by a secure element chip. Every reading is signed with a private key that never leaves the hardware — making forgery physically impossible.
Multiple sensors form a local network and reach cryptographic consensus on readings — even with no internet connection. A single rogue sensor cannot corrupt the record.
Each reading is committed to a hash chain anchored on Solana — every entry links to the one before it. Altering or removing any record breaks the chain and is immediately detectable. Only a compact commitment goes on-chain; raw operational data stays encrypted off-chain.
The proof is submitted to Solana on reconnection. Nobody — not us, not the shipper, not anyone — can alter it afterward. One immutable record. Verifiable by all parties instantly.
We're actively speaking with pharmaceutical cargo insurers and logistics operators to validate our approach. If cold chain claims disputes are a real cost in your business — we'd value 20 minutes of your time.
