The Stack

Trust infrastructure, designed like a product.

Each layer carries a specific responsibility, and each is independently verifiable. The consumer sees a single, calm interface beneath it, six systems in concert.

  1. 01
    Physical Product
    The garment, object, or asset itself.
  2. 02
    NFC / QR
    Embedded identifier tap or scan to open.
  3. 03
    Digital Twin
    A unique, persistent representation of the item.
  4. 04
    C2PA
    Cryptographic content credentials. Provenance, signed.
  5. 05
    Hedera Consensus
    Immutable, ordered, public timestamping.
  6. 06
    EV3 STAMP 〰️
    The trust seal that ties it all together.
  7. 07
    Consumer Passport
    A beautiful interface anyone can verify.
Standards Alignment

Built on the GS1 Sweden DPP Handbook. Ready for EU DPP 2027.

EV3 Stamp implements the full EN 18216 family that operationalises the ESPR Digital Product Passport, and speaks GS1 natively so brands do not have to re-identify a single SKU. What GS1 Sweden describes in its DPP handbook, EV3 Stamp ships.

How passport data moves between actors along the value chain.

EV3 Stamp
OpenAPI 3.1, versioned, covering create → repair → resell → recycle.

System interoperability

Passports from different issuers must resolve and validate against each other.

EV3 Stamp
C2PA manifests + Hedera anchor make every claim independently verifiable.
EN 18221

Storage, archiving, access

Long-lived, controlled access to passport data beyond the product's active life.
