Resolves to the live record. Anyone can verify; only the holder can transfer.
This certificate records a declaration and assessment made on Boss Tag. Its standing derives from the on-chain record above, not from this document alone.
This record is anchored on Polygon and cannot be altered or deleted — not by the seller, not by Boss Tag.
Digitize something you already own that no brand will passport — own the record forever, and prove it to anyone.
Scan any Boss Tag QR to verify — no account required.
Anchored on Polygon
A fingerprint of this record is written permanently to the Polygon blockchain. It proves the record existed in this form at that moment and has not been altered since — a record-integrity commitment, not a token or a financial instrument.

Polygonscan is a public blockchain explorer outside Boss Tag’s control — the proof does not depend on trusting us. On that page, the “To” address is the Boss Tag registry contract and the transaction’s input data contains the record hash shown above.
Run the proof yourself
Your browser rebuilds the record’s fingerprint from the fields on this page and checks it against the Polygon blockchain directly — nothing here depends on trusting Boss Tag.
Check this anchor without Boss Tag
The anchor is a public blockchain transaction. Open it on any Polygon explorer, read the stored hash, and compare it to the record hash below. No Boss Tag page, account, or company is needed for that check — now or later.
Signed statement: download this record’s signed statement and check it against Boss Tag’s public key with any JOSE library.
