DNAChain - Tamper-proof chain-of-custody for every sample.

Biological samples move between labs with surprisingly little accountability. Spreadsheets and paper forms are still the norm in most biobanks and CROs. DNAChain fixes this — every sample registration, transfer, and consent change is SHA-256 hashed and cryptographically chained. Alter a record and the chain breaks instantly. One-click compliance reports covering HIPAA, GDPR, and 21 CFR Part 11. Free to start. No credit card required.

Hey Product Hunt! 👋 I’m Ramon, the founder of DNAChain. I built this after realizing that biological samples — DNA, blood, tissue — move between labs, institutions, and custodians with surprisingly little accountability. Spreadsheets, paper forms, and disconnected LIMS systems are still the norm in most biobanks and CROs. DNAChain solves this with cryptographic hash chaining — every sample registration, transfer, and consent change is SHA-256 hashed and chained to the previous event. Tamper with a record and the chain breaks instantly. When a regulator asks for proof, you export a signed PDF in one click. We’re HIPAA, GDPR, 21 CFR Part 11, and GxP compliant out of the box — and we start completely free with no credit card required. Would love to hear from anyone in genomics, biobanking, or clinical research. Happy to answer questions about the technology or the compliance architecture. Try it free at dnachain.bio 🧬
