About

A Public Registry Built for Transparency.

Compound Ledger is a non-profit, open-access blockchain registry for Certificates of Analysis. Free to search. Free to submit. Permanent by design.

COA fraud is a solved problem.

The pharmaceutical and research chemical supply chain depends on Certificates of Analysis that can be forged, backdated, and substituted. Compound Ledger anchors the original COA document to an immutable blockchain at the moment of submission creating a public proof of authenticity that no party can alter after the fact.

We don't parse, interpret, or certify the contents of COA documents. We anchor them. What you find on this registry is the exact document the issuing laboratory submitted no more, no less.

01

Open Access

Every record is public. Anyone can search and retrieve records without an account, without a fee, and without restriction.

02

Non-Profit

No advertising. No licensing fees. No paid tiers. The registry exists to serve the public interest not to monetize access to safety information.

03

Immutability

Anchored records cannot be modified or deleted. A lab's submission is permanent, regardless of what happens to their account.

04

Minimal Friction

Labs submit in under two minutes with three data fields. No integration, no API, no contract.

Questions or partnerships

We work with accreditation bodies, regulatory agencies, and trade associations to expand registry adoption. If you represent an industry body or customs authority, we'd like to hear from you.
