For collectors
Every item you add gets a permanent public record — what it is, its standing, and who confirmed it. Share it, print it, sell it. The record transfers with the item to every future owner — and where a ruling on the item itself is confirmed with its authority, it reads independently authenticated, in gold.

Why it matters
A Boss Tag certificate is permanent, publicly verifiable, and yours to share with future owners. Boss Tag isn't a grader — where your item's ruling from a recognized grading house is confirmed with the authority that made it, that standing is entered on the record. Not a screenshot. A real provenance record.
Watches, sneakers, jewelry, art, classic cars, equipment. If it is valuable and you can document it, you can give it a permanent record. Boss Vision identifies the item; the record anchors permanently.
When you sell, the certificate transfers with the item. The full provenance chain stays intact. The next owner inherits everything you created.
The flow
Photograph your item from the angles that matter. Add the details that prove it is yours. The flow runs in your browser; no app required.
Boss Vision identifies what you have and assesses its condition and authenticity signals — evidence and caveats shown in plain language. It assesses; it does not authenticate. That word is reserved: a record reads independently authenticated only when a ruling on the item itself has been confirmed with the authority that made it — and the record names that authority.
Your certificate anchors on Polygon and gets a permanent public URL. Share it with anyone. The record transfers with the item when you sell.
Buying, not authenticating?
Every item on the Boss Tag marketplace arrives with its permanent certificate, verification history, and transfer log. You’re not buying the watch — you’re buying the provenance.
