Three Digital Product Passports

These are not mockups. All three passports below are stored and served the way a real one would be, signed with Ed25519 keys whose public halves are published as JWKS—the key behind the first two is linked below; the third card links the key that signed its event. The lifecycle timeline, the cryptographic verification badge and the evidence chain are all computed live from the signed content. No textile delegated act has been adopted yet, so no textile DPP can be conformant today—what you can check is the infrastructure. Request access to open one.

The demo tee is an item-level passport (GTIN + serial, so repairs and resale attach to one garment); the demo jacket and the Trama tee are model-level (one passport for every unit of the SKU). Both are valid ESPR shapes—the difference is what the QR on the label encodes.

Demo Cotton T-Shirt

A full circular journey: signed at manufacture, repaired by a certified operator, resold on a second-hand platform, and ultimately recycled fibre-to-fibre. Every event is signed by its real author—there is no mock data underneath the timeline.

  • Lifecycle events: repair → resale → recycle
  • Recycled content backed by a GOTS certificate
  • Origin declared by the brand, sourced from its tier-2 mill—referenced, not named

Demo Poly-Blend Jacket

The counter-example. Virgin synthetic blend with no recycled content, ending its life through downcycling instead of fibre-to-fibre—and with no supporting evidence filed for most of its declared datapoints.

  • Lifecycle events: repair → resale → downcycling after 22 months
  • Declared, but largely unproven
  • No recycled content declared

Operator-signed lifecycle event

Trama Organic Cotton Tee

A repair recorded and signed with the repairer's own key.

  • Lifecycle event: seam repair, signed with the operator's own key
  • One operator, one key: the brand has no write access to this event

What you are looking at

Cryptographically signed

Every passport version is signed Ed25519. Every lifecycle event is signed by its author—brand, operator, or responsible economic operator. Tampering invalidates the signature publicly.

Operator-authored events

Repairs, refurbishments and resales are recorded by certified operators—not the brand. The brand has no write access to those events.

Selective disclosure

Commercially sensitive datapoints are withheld from the public view and released only to the actors entitled to them. What you see here is the anonymous projection, not the full record.
