My role

Pushed the team to a stronger use case; built much of the Next.js, API and SDK prototype

Built with

Next.jsZKPassportZero-knowledge proofsXRPL TestnetDIDs

Embeddable verification flows using ZKPassport proofs and the XRPL Testnet, designed to confirm attributes such as age without revealing a full identity.

   The problem

   Our first ideas used a blockchain because the theme said so, not because the chain added anything. About six hours and two pivots in, we landed on private attribute verification, where it does.

   What I did

   • Challenged the weak early directions and helped align the team on the stronger use case.
   • Spent most of the build on Next.js, API routes, the ZKPassport SDK integration and embeddable verification flows.
   • Focused on making verification easy for a business to drop into its own checkout.

   What the team did

   • Explored and pivoted together, then shipped a working prototype inside 24 hours.

   Afterwards

   I later pitched ApprovID to founders and ecosystem teams at Paris Blockchain Week and kept building relationships in the industry afterwards.
