d3 Vault

d3vault.eu · Escrow copy

The digital product passport stays findable if the platform disappears.

Backup for passports that do not sit on D3 Passport or D3 Battery. Copy, hash, RFC 3161 timestamp, public resolve URL. No EU certification, no Art. 10(4) fulfilment.

What you get

Third-party DPP platform or self-hosting: a copy that resolves in public. No TSA stack of your own, no portal project.

Copy outside the primary system

The API takes the passport, stores it and hashes SHA-256. The primary system stays yours — Vault is only the deposit.

Timestamp without a chain team

RFC 3161 timestamp on the hash. Integrity is demonstrable without you running nodes.

Scannable and public

Resolve URL without login, PDF with QR. For audit, labels, and the case that the origin platform no longer answers.

Kept apart from D3 SaaS

Ingest from d3 Passport or d3 Battery is refused. The same operator must not sell Vault as an “independent” copy for its own platforms.

Pricing

API licence for third-party platforms and self-hosting. Invoice by hand, plus VAT. No Stripe, no uptime SLA.
