Verified pedigrees.
Permanently provable.

Blockchain-anchored credentials for canine, equine, and bovine registrations. Etched by recognized authorities. Verifiable anywhere, by anyone.

Polygon-anchoredOpen verification — no account required
The fraud problem is real

Paper documents. Cash sales. No way to verify on the spot.

canine

$5,000 puppy. Forged AKC papers.

Counterfeit pedigrees and falsified health clearances thrive in cash-heavy puppy sales. Buyers have no way to verify on the spot.

equine

$70,000 yearling. Falsified Coggins.

Bloodstock fraud and altered race records sit beside legitimate paperwork at every major sale. Pre-purchase verification is slow and trusted on paper.

bovine

$6,000 Wagyu heifer. Wrong percentage.

Premium beef programs depend on breed purity claims. Without independent verification, mislabeled cattle move through the chain unchecked.

How it works

Trust anchored by the issuer. Open to everyone.

  1. Step 1

    Recognized authorities etch credentials

    Breed registries, kennel clubs, health testing bodies, and racing commissions etch blockchain-anchored credentials. The blockchain proves who etched what, when.

  2. Step 2

    Animals carry QR codes

    On registration papers, kennel cards, sales catalogs, brand inspection sheets, and stall placards. Any QR-capable phone can read them.

  3. Step 3

    Anyone verifies in seconds

    Scan with our free verifier app, or visit any chainBreed verify link. See the credential, the issuer, the chain, and the lineage — instantly.

Powered by Polygon

The whole stack is open. No private gatekeepers.

The BreedRegistry contract is deployed to Polygon mainnet and verified on PolygonScan. Anyone can independently check whether a credential exists, who etched it, and whether it has been revoked — without ever creating a chainBreed account.
