A seller may have a brand certificate, a receipt, an NFC tag, or none of them. A buyer needs to know which evidence is genuine, which object it belongs to, and what VerifyVault actually examined.
SERVICE IN PREPARATION · This page explains the proposed verification standard. It does not accept items or issue certificates yet.A trustworthy resale passport should distinguish an issuer’s own record from a third party’s physical assessment and from documents supplied by the seller.
An official digital certificate or product record, checked through a brand-controlled source when accessible. The passport identifies the issuer and exactly what was confirmed.
Highest provenance when the item-to-record link is intact.A qualified reviewer examines the actual item, its construction, identifiers, condition, and supporting evidence. The conclusion names its reviewer, date, and limits.
Independent opinion; never presented as brand endorsement.Receipts, photos, listings, and ownership claims can support a review. They remain seller-provided until their origin and connection to the item are checked.
Unverified submissions cannot create an authenticity claim.Dior lists a secure NFC chip on a B33 Spin sneaker that provides access to its Digital Certificate of Authenticity. That issuer record is valuable evidence for that specific product line.
VerifyVault would check the live brand-controlled experience where permitted, examine the physical pair and chip, and record any gaps. A screenshot or copied tag alone would not be enough.
No official Dior partnership or integration is claimed.
Capture item photos, identifiers, condition, and seller evidence.
Inspect any brand-issued credential through its original source.
A qualified reviewer examines the physical item and tag.
Publish a scoped decision with a unique VerifyVault ID and current status.
Buyer accepts after inspection; record ownership and any on-chain proof.
Select the evidence available for a resale item. This guide explains the next verification step; it does not authenticate an object or access any brand registry.
Every selection is hypothetical. A real decision requires the source, scope, item match, and reviewer to be documented.A brand-issued passport remains under its issuer's rules. VerifyVault could record a separate accepted handoff in its own passport, and later anchor that event to IOST Layer 2. A VerifyVault record would never claim to move a Dior, Aura, or other brand credential without an authorized integration. Personal owner details would remain private.
It should never collapse “a brand certificate exists,” “an independent reviewer inspected the item,” and “the seller uploaded a receipt” into the same green checkmark.
Any future IOST Layer 2 entry would preserve a fingerprint and event history. It would not independently prove the physical object is authentic.
EU timing: The European Commission plans the textile-specific delegated act for Q4 2027, followed by implementation measures and a transition period. The July 2026 DPP registry launch did not make textile passports mandatory.
Industry context: Aura describes digital product passports, authenticity, transfer of ownership, and resale features. Aura’s brand-issued infrastructure is separate from VerifyVault’s proposed independent resale review.
