Stacks 2.0 Hackathon Series
When one hackathon ends, another begins! The Stacks 2.0 Hackathon series is a non-stop virtual event packed with ways to get involved in the Stacks ecosystem as we work toward the Stacks 2.0 launch. Starting with the (much requested) return of the Clarity Smart Contract Hackathon, we'll reveal details about each new hack in the series as we go, running the series all the way through the launch of mainnet. There will be big prizes, great judges, amazing connections, and a lot of fun.

FAQ
Email [email protected] if you don't see an answer you need!
Am I eligible?
You must build and submit a new Clarity Contract to be eligible. It will be at the discretion of PBC if it is suspected someone is trying to game the system by trying to make slight changes to an existing smart contract for the reward. Lastly, participants need to be over 18 years of age, and adhere to the hackathon rules.
What are the rules?
All submitted contracts must be open source. Your contract source code must be publicly available on GitHub, Gitlab, or similar publicly accessible links. Once public, contracts can then be submitted through Devpost.


Requirements: Contracts must have basic testing and documentation to qualify.
