About the challenge

Welcome to HackPrinceton Fall 2022, a student-run hackathon by Princeton University.

At HackPrinceton, you'll meet fellow hackers from around the world, learn new skills, and work alongside seasoned mentors. We'll have free workshops, lecture series, mentorship, prizes, games, and more. Don't have a team, or even an idea? Don't worry! We'll give you the tools to build something incredible.

For 36 hours on November 11-13, you’ll have the opportunity to collaborate and build out brilliant, innovative, and impactful ideas.



1. Game Design

2. Art

3. Sustainability

Sustainable practices support ecological, human, and economic health and vitality. The sustainability track is for hackers who aim to improve environmental sustainability through the use of technology.

4. Healthcare

Health-focused projects can take on public health challenges (ex: COVID-19, etc) or personal wellness (nutrition, mental health, fitness, etc).

5. UX/UI Design

6. Machine Learning/AI


1. You must submit a link to your project's public GitHub repository created between November 11-13, 2022.

2. You MAY submit an OPTIONAL video demo that does not exceed 2 minutes in length. Remember to leave time to upload your video to YouTube/any other platform and add the link to your video to your Devpost submission. 

3. Judging will be from 9:30am-11am on Sunday, November 13th. Hackers will be expected to present their finished work in front of the judges during this time period. You must prepare for a presentation explaining/demoing your project to the judges that does not exceed 2 minutes in length, even if you attached a video to your project. Your presentation should clearly indicate the problem your hack attempts to solve and a walkthrough of your hack’s functionality.

Please add your Discord usernames to your submission so we can contact you if you win a prize!

We want you to use your hacking skills to find and build solutions that put opportunities and resources within reach to all communities.

Best Use of DeSo (MLH)

DeSo is the official Web3 sponsor of the MLH Hackathon League and the first Layer 1 blockchain custom-built for decentralized social media applications. While a blockchain like Avalanche costs $0.50+ to store just a 200-character post, the DeSo blockchain is built with custom indexing and storage optimizations which make it 10,000X cheaper to store social content on-chain! In order to qualify for the contest, build a hack that uses the DeSo API. While social media apps are a great fit for DeSo, you can also build financial apps, marketplaces, and more on the DeSo blockchain. To get started, sign up for a DiamondApp account, make a post tagging @deso with both your event hashtag & #MLH. The DeSo team will then send you even more $DESO coin to build your hackathon project! On top of that, the team with the Best Use of DeSo gets $100 worth of $DESO coin, an exclusive DeSo branded tumbler, and a YubiKey Security Key!
