The Golden Nut
Our top award for Nut November, given to the project that stood out in scope, execution, and impact.
🏆 Winner: The Nutty Pill
A bitcoin education app, where ecash is locked behind an admin dashboard and the learner unlocks the sats by working through lessons and quizzes. Roughly 85 lessons across a range of topics, everything running locally with Cashu. Smart concept, strong execution. A well deserved grand prize.
