ERC721 Authenticity Token
MVP for Genuino World: ERC721-based authenticity and lifecycle tracking for phygital football jerseys with RFID-linked identity.
This was an MVP for Genuino World, built around the idea of treating a physical football jersey as a phygital ERC721 asset. Each jersey had a digital identity tied to proprietary hardware and embedded RFID tags, so authenticity and product history could be checked against an on-chain record rather than a conventional certificate.
My work focused on the smart-contract layer and the jersey-management side of the application. The contract did more than mint ownership tokens: it also tracked events associated with the jersey, including location-related data intended to help prove that an item had actually been used in a match context.
Around that, the product stack included a React web dashboard for management flows and a React Native / Expo mobile app for the physical verification experience. The combination pushed the project toward product identity, provenance, and real-world asset tracking rather than collectible NFTs.
