Join WebZero's sub0 Hackathon: Build Real Products with $41,000 Prize Pool
Are you ready to build and launch real blockchain products? WebZero's sub0 Hackathon invites developers, marketers, and innovators to a 72-hour creation marathon from November 14 to 16, 2025, in Buenos Aires, Argentina. This exciting event takes place during the Polkadot flagship conference, sub0 SYMBIOSIS.
With a generous $41,000 USD prize pool, teams compete across four main tracks, each winner taking home $4,000. Prize payouts are split evenly: half awarded during the hackathon and the remaining half upon shipping the final product. The goal is clear — prioritize shipping real, functional products instead of proof-of-concept prototypes.
Participants can comprise diverse teams, including marketing specialists, to refine product-market fit, ensuring a broad and impactful approach. Remote participants are welcome, as long as they actively collaborate with on-site teams.
Post-event, winning teams receive dedicated mentorship from top names like OpenZeppelin, UX Bounty, R0gue, and PAPI, helping finalize and maintain the projects beyond the hackathon.
Arkiv (formerly Golem DB) is a proud sponsor contributing $10,000 to the prize pool, supporting the creation of innovative decentralized solutions.
