Born day one
A partner brand mints the passport when a customer buys new. The item auto-lands in the buyer's CirqlStash carrying a GS1 carrier from the first sale — and the brand keeps a lifetime link through every owner that follows.
CirqlPass · Public resolver
Every CirqlPass carrier resolves to a hosted passport: an append-only record of an item's whole second life — minted, graded, listed, sold, transferred, repaired, recycled. Trust-graded attestations, never certifications. This is a public demo with sample data.

Append-only log — the state above is a projection over the events below. CirqlPass records trust-graded attestations, never certifications, and complements the official EU Digital Product Passport.
Born day one. The bike landed in the buyer's CirqlStash with a GS1 carrier from the brand — the identity exists before it is ever resold.
New chain and cassette fitted; brakes bled. Logged against the frame number.
Item came back through a verified operator door. Condition graded from photos and a mechanic check — an operator attestation, not a certification.
Provenance rendered on the listing as a trust signal — full history visible to the buyer.
Settled through the escrow rail. The settled deal — not a free-floating button — authorizes the transfer.
Custody flipped when the buyer scanned the GS1 carrier against the settled deal. History preserved end to end.
How a passport is born
Minting is opt-in, per item — an identity can be born at first sale, at resale intake, or claimed by hand. Every door writes to the same append-only log; the door only sets how much its first events can be trusted.
A partner brand mints the passport when a customer buys new. The item auto-lands in the buyer's CirqlStash carrying a GS1 carrier from the first sale — and the brand keeps a lifetime link through every owner that follows.
When no brand passport exists, a verified CirqlImport operator mints one the moment the unit is on the intake counter — matched to the reference model and printed as a GS1 label. It's the most controlled door, and where a broken chain heals back to high trust.
Anyone can add a lighter passport themselves. Self-reported events read as lower trust and honestly say so — but the chain still heals to high trust whenever the item passes back through a verified operator door.
How a passport is carried
Every passport rides on one scannable carrier. It's a GS1 Digital Link — a standard, future-proof URL that names both the product model and the exact physical unit.
