The challenge

Physical merch goes dead the moment it is sold. It cannot prove who owns it, unlock anything, or connect a brand to the person wearing it. Merchadise wanted the opposite: a shirt that is also a key, a proof of ownership, and a direct line to the customer, and it had to feel effortless to people who have never touched crypto.

How we thought about it

The whole trick was to hide every hard part behind one tap. We scoped the experience around a single action, scanning the code on the shirt, and engineered everything difficult, account creation, secure custody, issuing the ownership record, to happen silently underneath it.

What we built

A QR code per product
Every shirt is printed with its own custom code that ties that physical item to a digital identity.
An account from your email
Scanning silently creates a secure account from your Gmail, Discord or X. No wallet to install, no seed phrase, no jargon.
Proof of ownership, issued to you
A tamper-proof record of that exact shirt is issued straight to the new account, so ownership is provable and portable.
Shipped as an SDK
We packaged the whole flow so it drops into a catalog and scales across products, from shirts to any piece of merch.

The result

We proved a physical product can carry a real digital identity without asking the customer to learn anything new. Scan a shirt, and a secure account and provable ownership appear in seconds. It reframes merch as a membership: the thing you wear becomes your pass, your ticket, and your line to the brand.

  • A physical shirt that provisions its own secure account and proof of ownership from a single scan, with zero crypto knowledge required of the wearer.
  • Accounts created straight from a customer’s email, Discord, or X, so onboarding feels like signing into any modern app.
  • Delivered as an SDK, so the same connected-product flow drops into a catalog and scales from one shirt to an entire product line.
  • A blueprint for merch as membership: the product doubles as a VIP pass, an event ticket, and a direct, ongoing channel to the people who wear it.
