◆ DARPAN · দর্পণ · THE MIRROR

The Digital Product Passport, from the brand's side.

Darpan is where apparel brands take their suppliers' verifiable credentials, attest to them under their own authority, compose a product passport, and submit it for ESPR — then render it for shoppers however the brand needs. The mirror that turns supplier evidence into a passport you can stand behind.

Built on GS1 Digital Link and W3C Verifiable Credentials — the formats the regulation is converging on.

Start today, not in 2028

The passport is tomorrow's obligation. Verified sourcing is today's advantage.

The ESPR deadline is a multi-year horizon — but the supply base you'll build the passport from is a decision you make now. The same platform that will compose your DPP already lets you find and shortlist verified factories on Provena Source: capability and compliance graded by evidence, not self-declared. Source through it today, and that supplier evidence becomes your passport tomorrow.

The mandate

What ESPR asks

Under ESPR, textile products sold in the EU will need a machine-readable Digital Product Passport — materials origin, recycled content, repairability, footprint.

The brand's job

Not issuing the data

Suppliers do that. The brand has to attest to it, compose it, keep it current, and put its own name behind the submission.

The hard part

Not a one-time file

It has to stay fresh as products and suppliers change — and reconcile against what the supplier actually signed.

Where it sits

Proman issues. Darpan consumes.

Your suppliers issue signed Digital Product Passport credentials at the source, in Proman — cotton origin through cut-and-sew, each one cryptographically signed by the party that created it. Darpan is the exact inverse: the brand-side platform that receives those credentials, attests to them under your own key, and assembles the passport you submit.

Because both sit on the same record, you're never re-keying a supplier's data or guessing whether a certificate is current. What they signed is what you compose from — and you can see it.

The lifecycle

From a supplier's credential to a submitted passport.

Darpan owns the full path. Five stages, each one building on signed evidence rather than re-collected paperwork.

Stage oneIntake

Receive what suppliers signed

Supplier credentials arrive through the credential inbox — issued in Proman, or imported from existing sources. No re-typing; no chasing PDFs. The signature travels with the record.

Stage twoAttest

Put your name behind it

The brand attests to supplier credentials under its own signing key — a brand-signed verifiable credential that says, on the record, that you stand behind this evidence.

Stage threeCompose

Assemble the product passport

Attested credentials compose into a per-product Digital Product Passport — materials, origin, recycled content, repairability — with full per-field lineage back to the credential each fact came from.

Stage fourFreshness

Keep it true over time

A passport isn't static. Darpan tracks freshness — flagging when a supplier credential expires, a product changes, or evidence goes stale — so what's published stays accurate, not just accurate at launch.

Stage fiveExport

Submit, and render for shoppers

Export to ESPR in the formats the regulation expects, and serve the consumer-facing passport behind the QR code — hosted by Provena, themed to your brand, or rendered on your own infrastructure via API.

Rendering the passport

However your brand needs the shopper to see it.

The same composed passport, three ways to put it in front of a customer — from zero setup to full control. Pick per product line; change later.

What's inside

Made for brands who'll answer for every claim.

Brand-signed attestation

Every passport carries a verifiable credential signed under your key — your formal attestation, recorded, not a checkbox in someone else's database.

Per-field lineage

Every fact in a passport traces to the supplier credential it came from. When an auditor asks where a number came from, the answer is one click.

Freshness tracking

Expiring credentials and changed products surface before they become a stale public claim.

Credential inbox

A single place supplier credentials flow into — from Proman or imported — so intake is a queue you work, not an inbox you dread.

Standards-native export

GS1 Digital Link, W3C Verifiable Credentials, JSON-LD — the passport leaves Darpan in the formats ESPR and the wider ecosystem are converging on.

Consent-governed sharing

Suppliers control what each brand sees, brands see what they're entitled to, and both look at the same record.

Built on open standards

Not a proprietary format you'll have to migrate off later.

Darpan speaks the standards the regulation and the supply chain are standardizing on — so the passport you compose today stays portable, verifiable, and machine-readable as the ecosystem matures.

One platform

The same signed records, every market.

Darpan is the EU brand's side of a record that runs from the factory floor to customs. The evidence is issued once and consumed wherever it's needed.

Proman Supply side

The factory side. Suppliers issue signed DPP credentials for every tier of the chain — and publish a verified profile to Provena Source.

Darpan EU brand side

The EU brand side. Attest, compose, keep fresh, and submit the Digital Product Passport.

US compliance

The US importer side. The same records, turned into forced-labor readiness and a customs-ready dossier.

Make the passport yours to stand behind.

Whether the ESPR deadline is on your roadmap or already on your desk, let's walk through what your supplier data looks like today — and what it takes to compose a passport from it.
