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.
