Midwest Blockchain Conference Hackathon 2025

About the challenge The MBC 25 Hackathon is a one-week, builder-focused competition that brings together developers, designers, researchers, and creators to build the next generation of on-chain applications. Hosted during the Michigan Blockchain Conference, the hackathon gives participants the chance to turn innovative ideas into fully functional prototypes while receiving mentorship from leaders across the Solana and Base ecosystems. Hackers can submit to one main track—Solana or Base—depending on their preferred stack. Both tracks emphasize technical depth, originality, strong UX, and real-world impact. Teams may also submit to optional sponsored bounties from Polymarket and Circle for additional prizes. Throughout the week, participants gain access to workshops, office hours, and direct support from ecosystem engineers, offering a hands-on environment to learn, iterate, and ship. The top 10 teams will be invited to pitch live at the MBC closing ceremony for a chance to win part of the $40,000 prize pool. Get started
