“My father bought vitamins that turned out to be counterfeit. He had no way to check. That’s why I built Certapharm.”

Ysrael de Jesus Sacramento, founder · Universidade Federal de Sergipe, Brazil

The problem

Counterfeiters copy the most expensive drugs. Patients can’t tell.

1 in 10medicines in low- and middle-income countries is substandard or falsified.
$30.5Bspent every year on these products.

How it works

One signed trail, from factory to pharmacy.

  1. 01AccreditCertapharm accredits each company in the chain. On-chain we keep a hash of its CNPJ, never the number.
  2. 02CertifyThe manufacturer certifies the batch with its own Solana Attestation Service credential. Nobody else can withdraw it.
  3. 03Sign custodyCarrier, distributor and pharmacy each sign their hand-off on Solana, with temperature.
  4. 04Seal and verifyEach box gets a compressed-NFT seal. Anyone verifies with a phone, or audits on the Solana explorer.
