Welcome to HackPrinceton Spring 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 April 1st - 3rd, you’ll have the opportunity to collaborate and build out brilliant, innovative, and impactful ideas.



1. Social Good

Social good is the concept of generating a positive impact for the public. The social good track is for hackers who strive to make the world more equitable using community-focused applications of technology.


2. Education

Education projects are focused on lowering the barrier of entry to knowledge. The education track is for hackers who seek to make education more accessible and bring awareness to certain topics.


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. Health

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



1. You must submit a link to your project's public GitHub repository created between April 1-3, 2022.

2. You must submit a 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. Demo videos 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!

Best Use of DeSo

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, you must launch an app that writes to the DeSo blockchain and implements DeSo identity. While social media apps are a great fit for DeSo, you can also build financial apps, marketplaces, and more on the DeSo blockchain. For inspiration on project ideas, you can check out some of the existing 200+ apps already live on DeSo at Bithunt.com as well as our DeSo APIs. The Best Use of DeSo gets $100 worth of $DESO coin & an exclusive DeSo branded tumbler!

Most Creative Use of Twilio

Twilio allows you to incorporate mobile messaging, phone calls and a ton of other awesome communication features right into your hackathon project using a web service API. Are you building an e-commerce website and want to send text notifications or email confirmations once an order is completed? Or maybe you'd like to verify users based on their mobile numbers? Twilio makes all this possible and more. Build a hack that simplifies your life using any Twilio API for a chance to win some awesome prizes! Get started with $50 in free credit!

Best Web Monetization Project

Coil is all about providing better ways to access and reward the creators, publishers and platforms that you love. Coil members get to view web monetized sites while streaming micropayments directly to the website owner, or in this case, you! In turn, you can react to payments in real time by displaying a thank you message, unlocking bonus content, features and so much more! Build a web monetized hack using Coil for a chance to win an Anker Quick Charge Portable Charger, Coil pin and $60 Coil credit redemption card!

Best Use of Auth0

Auth0 wants your applications to be secure! Use any of the Auth0 APIs for a chance to win some exclusive swag, including a Miir 12oz tumbler, Rubiks Cube, and sticker! Why spend hours building features like social sign-in, Multi-Factor Authentication, and passwordless log-in when you can enable them through Auth0 straight out of the box? Save some time on your hack and set yourself up for a big win. It doesn't take much to get started. Auth0 is free to try with up to 7,000 free active users and unlimited log-ins. Make your new account today!
