What this page can tell you
Registered number
This number is registered by Atelier SealTrust (demo). A QR code can be copied: on its own, it does not prove that the item in your hand is the original.
What to do
- If the label shows the contactless symbol, hold your phone against that symbol: the chip proves that the item is the original.
- Buy from a seller you trust and keep the proof of purchase.

What the passport says
Passport data is served in tiers, depending on who is reading it. What you see here depends on your level. The EU ESPR regulation defers that split to delegated acts, none of them published yet: our six tiers are therefore defaults, aligned on the Commission Joint Research Centre methodology.
An account opens other tiers: owner, repairer or recycler accredited by the brand, market surveillance authority. Sign in to see the ones open to you.
PublicYour tier
Basic identification, compliance labels, recyclability, available to everyone via the QR code or NFC chip.
End user
Environmental impact, circularity, durability, for the consumer and the product's owner.
Repairer
Bill of materials, disassembly instructions and repairability index, restricted to repairers the brand has accredited.
Recycler
Materials and substances of concern, restricted to recyclers the brand has accredited.
Upstream supplier
Materials, manufacturing and supply-chain provenance, restricted to the brand's own teams and to market surveillance authorities. No partner accreditation opens this tier.
Authority
Full access, restricted to market surveillance authorities.
What this page proves, and what it does not
- The brand registered this product and published its passport.
- A fingerprint of the content was written on a public blockchain on September 3, 2026: if the content changes afterwards, it shows.
- A copy of the content is kept on IPFS, a public network outside our servers: anyone can compare it with this page.
- A QR code can be photocopied. It proves that this number exists at the brand, not that the item in your hand is the original. Only a contactless chip proves that.
What this does not prove
That the information declared by the brand is accurate. It remains the brand's responsibility; the proof only shows that it has not changed since it was written on the chain.
SHA-256 : c52492ea8b828eb800974eb94713151aca7ac1cb7f29cf00a583c088b123d43d
This unit belongs to a batch whose Merkle root is publicly anchored on the Base blockchain: anyone can verify its membership of that batch, independently, at any time. The anchor commits to the unit's identity: its token, its UID fingerprint and its ERC-721 metadata hash. The passport's SHA-256 fingerprint above is published and anyone can recompute it, but it is not part of the Merkle leaf.
Schema 1.0
This Digital Product Passport is issued by SealTrust. The proofs on this page bear on the integrity and origin of the declaration, not on the accuracy of the values declared by the brand.
