For Resellers, Laboratories, Pharmacies, Manufacturers, and Trusted Certificate Issuers
Protect your Certificates and Identities
A legitimate Certificate of Analysis can be copied, reused, or linked to the wrong seller, product, or batch. COA Chain protects the connection between the verified organization, registered certificate, and authorized use.
Buyers can confirm who registered the COA, whether it matches the protected version, which product or batch it covers, and whether the record is active.
COA Chain verifies the full trust relationship—not merely the document a QR code opens.
COA Chain connects the registrant, certificate, product or batch, and current record status through one controlled verification path.
An authorized laboratory, pharmacy, manufacturer, seller, or certificate issuer registers its identity and submits the COA, document version, and product or batch information.
Learn About Registration →COA Chain creates a protected digital record linking the document fingerprint to the verified registrant, authorized relationships, status history, and blockchain evidence.
What Is a COA.1? →Anyone can scan or search the COAScan ID to confirm the issuer, document match, product or batch association, authorization, and record history.
