Hackathon Chiliz 2025 - Paris

The Challenge
Built during the Chiliz Hackathon 2025 in Paris, Ultras is a gamified sports betting app for fans. Our team designed and developed a complete mobile experience in just 48 hours, featuring real-time odds, social betting pools, and fan engagement mechanics.

The Solution
The app earned the Fan Favorite Award, voted by fellow participants. We combined React Native with Expo for rapid prototyping, creating an intuitive UI that resonated with the hackathon audience and judges alike.
