Blockchain Hack Warsaw - Submissions

About Blockchain Hack Warsaw

Blockchain Hack Warsaw is a Solana hackathon organized by Superteam Poland.

It starts onsite in Warsaw on September 26 - 27, 2026. This is the kickoff. You form your team, start building and work side by side with mentors. It's the best moment to ask questions, get feedback on your idea and get help with technical problems.

After the onsite weekend, the hackathon continues. You have until October 11 to keep building and improving your project. When it's ready, submit it here for judging.
