NFTIZE for Her-Age — modernising a Shopify app that turns authenticated luxury pieces into digital passports.

Context

Her-Age is a curated platform for authenticated vintage and pre-loved luxury — selective intake and quality control at every step. NFTIZE is their internal Shopify app that turns a verified piece into a digital passport with an immutable history from first expert review through listing and resale.

The authentication system needed modernisation: data inconsistencies, brittle embed scenarios, deprecated endpoints, and opaque status transitions blocked scale.

What we changed

We aligned data models with current Shopify APIs, rebuilt critical flows end-to-end, and redesigned status UX so experts, sellers and buyers always know where an item sits in the pipeline.

• Modern Shopify API usage — GraphQL-first where appropriate, deprecated REST removed
• Consistent entity model linking products, verification jobs and passport records
• Transparent status machine — expert review, revision, approved, published, transferred
• Hardened embed and admin surfaces — fewer edge-case failures during peak intake

Expert and buyer experience

Experts work through a guided flow: evidence upload, condition grading, authenticity decision, passport minting. Sellers see progress without support tickets. Buyers get a verifiable digital passport tied to the physical item.

Outcome

Faster, more reliable authentication. Clearer interfaces for every role. A foundation Her-Age can scale without re-architecting the core app every season.
