Masterz × IOTA EU

10,000 swimming pools

full of t-shirts. Buried or burned.
Every year. In Europe alone.

What if every t-shirt had a passport
that follows it from factory to recycling bin.
And rewards you for closing the loop?

02 — Problem

Once a shirt leaves the store, brands lose visibility, recyclers lack context, and consumers have no incentive to repair or recycle. Without traceability and rewards, circularity in textiles remains theoretical rather than real.

03 — Supply Chain Pod
Immutable and Trustworthy Systems

With IOTA, you can design solutions that bring trust and traceability across the full supply chain.

What you'll learn
  • Digital trade and process automation
  • Cross-border efficiency
  • Real innovation in product traceability

04 — Objectives
Supply Chain Track
Product traceability beyond the factory
No visibility in the consumer journey — once a product leaves the factory, the chain goes dark.
Consumer reward mechanisms
No incentive system exists for consumers who participate in circular economy actions.
Compliance infrastructure
EU regulations require verifiable product data by February 2027 — most supply chains aren't ready.
Digital Identity Track
Data ownership & transfer
Who owns product data as it moves through the lifecycle — and how is it handed off?
Privacy & anonymity
Consumers, producers, and recyclers need to interact without exposing each other's identity.
Cross-system interoperability
EU compliance demands data flows across systems and jurisdictions — no walled gardens.
05 — What We're Building

We leverage IOTA's Digital Product Passport (DPP) framework to give every garment a persistent digital identity across its lifecycle.

Each shirt becomes a verifiable, machine-readable record. Trusted actors — such as recyclers, repair shops, and brands — can update lifecycle events via a role-based entity hierarchy, ensuring only authorized events trigger actions.

When lifecycle conditions are met, consumers are rewarded.

↓ technical architecture to follow
06 — Considerations

The EU will likely roll out its own textile DPP scheme as part of legislation, so we're designing for interoperability and compliance from the start.

07 — Impact

Every garment gets a verifiable digital identity that persists from factory to consumer to recycler. Consumers see the full story and get rewarded for returning products. Brands maintain visibility throughout the lifecycle. Recyclers verify materials with proper context. All EU-compliant, all interoperable, all actionable.
