# **Introduction** Let's get ready to build! Buidl Battle is a competition designed to celebrate and strengthen innovative projects built on Bitcoin. This three-week virtual event invites builders to put their projects in the spotlight, connect with investors and accelerators, and engage with other builders in the Bitcoin builder community. During Buidl Battle, projects and builders will gain the spotlight and momentum to level up their work, while fresh talent will be welcomed into the ecosystem. Much more than a competition, Buidl Battle is a celebration and a launching point for the next wave of Bitcoin builders 🚀🚀 Questions?

The main hackathon is open submission, meaning you can build whatever you want as long as it uses Stacks. For the main hackathon, we’ll have a panel of judges with varying expertise to get a well-rounded vie of your project. There is one round of judging and judges will select first, second, and third place. In addition to to the main hackathon, there are three bounties of $3,000 each up for grabs. Anyone is eligible for a bounty, including if you win one of the top three spots in the main hackathon. Bounties will be centered around specific themes and an expert in that particular theme will select one winner per bounty. Specific bounty themes will be announced soon. All winners will be announced March 31st. # **Prizes** ## **$20,000 in total prizes are available for this competition!** Below is the breakdown of the prizing structure for the main hackathon and the bounties. ## Main Hackathon - 1st Place - $6,000 - 2nd Place - $3,000 - 3rd Place - $ 2,000 ## **Bounties** $3,000 across 3 bounties, to be announced before hackathon start date. ## **Bonus Prizing** In addition to any monetary rewards, the **top three projects** from Buidl Battle will receive continued ecosystem support designed to help turn their Buidl into a real, production-ready product. This includes: - An **introduction to the Stacks Endowment**, providing guidance on potential funding pathways and long-term ecosystem support. - A **1:1 working session with Stacks Labs**, focused on project progress, technical direction, and next steps for continuing to build within the Stacks ecosystem. These sessions are intended to be practical and forward-looking — helping teams refine their roadmap, identify gaps, and understand how to move from hackathon project to real-world deployment. This bonus support is designed to accelerate serious teams beyond the hackathon and deeper into the Stacks ecosystem. # **Judging Criteria** The panel of judges will evaluate and select the best project 3 projects.
