The item is yours. The proof should be too.
A Boss Tag certificate is permanent, publicly verifiable, and yours to share with future owners. Not a third-party authentication report. Not a screenshot. A real provenance record.
For collectors
Authenticate it. Own it. Prove it.
Boss Tag authenticates valuable items and creates a permanent provenance record. The certificate travels with the item to every future owner.
- Polygon-anchored
- Public verification
- Transferable
Why it matters
Built for what you actually own.
Watches, sneakers, jewelry, art, classic cars, equipment. If it is valuable and you can document it, you can authenticate it. Boss Vision identifies the item; the record anchors permanently.
Designed for the next owner, not just today.
When you sell, the certificate transfers with the item. The full provenance chain stays intact. The next owner inherits everything you created.
