Background

What is Digital Product Passport?

A DPP is a verifiable digital record attached to a physical product — scan it, and you see what it's made of, where it came from, and its environmental footprint.

Under the EU's ESPR, the DPP becomes mandatory in the years ahead — the regulation, not a nice-to-have.

Your problem

No Digital Passport,
No EU Market.

Every product sold into the EU will need a verifiable Digital Product Passport — materials, origin, footprint, stitched across dozens of suppliers.

If you make the product

The factory

Your buyers will demand full supply-chain data — your suppliers, your costs, your processes.

If you sell the product

The brand

The compliance liability is yours. But your suppliers won't hand over the data — so you're left guaranteeing claims you can't verify.

Factories can't comply without leaking. Brands can't comply without the leak.Someone has to break the deadlock.

Our solution

Prove compliance — without handing over your data.

Immutable

Secured by blockchain

Once recorded, your passport data can't be altered — not by your buyers, not by us.

Private

Powered by zero-knowledge proofs

Your suppliers, costs, and processes never leave your hands.

Verifiable

Powered by zero-knowledge proofs

Brands, auditors, and regulators can confirm every claim — without seeing the data behind it.

Both technologies are backed by formal academic proofs — and packaged so you never have to think about them.
How it works

Four steps. No new infrastructure.

1

Input

The factory places its data in a secure workspace — visible to no one else.

2

Process

Our agent formats the data into the DPP schema — and encrypts anything you choose to keep private.

3

Upload

The DPP is published with cryptographic guarantees: tamper-proof, and even the hidden parts stay verifiable.

4

Verify

EU authorities verify the passport directly; consumers scan a QR code to see its public information.

Works alongside your existing systems — data in, passport out. No ERP overhaul, no process redesign.
Why us

The rare team where cryptography meets the factory floor.

Research

Research-grade cryptography

Security

Security you can audit

Our engineers build and secure production systems in industry today. Your data is handled to professional security standards.

Access

Floor-level access

Direct ties into Taiwan's manufacturing market — the beachhead where >70% of the world's functional fabric is made.

Getting started

Start with one product line.

You provide

Almost nothing new.

  • One product line and the supply-chain data you already have
  • One point of contact — a few hours a week
  • No system changes, no upfront integration
You get

A passport, and a plan.

  • A complete, EU-ready Digital Product Passport for that line
  • A gap report: what data you're missing before your 2028 deadline
  • A roll-out blueprint for the rest of your catalog
Zero risk to your operations — your data stays in your control, even during the pilot.
Appendix

How does a zero-knowledge proof work?

A prover convinces a verifier that a statement is true — while revealing nothing beyond the fact that it's true.

This is what lets you prove your passport is genuine without handing over a single supplier name.

Verify everything. Reveal nothing.
