With the rapid advancement of technology, it is important to use its power in ways that benefit society. HackDavis challenges its participants to hack for social good, and create an opportunity for us to explore the intersection between technology and society.

On April 16-17, over 750 students, hackers, and creators will come together for 24 hours of hacking. For the 7th year in a row, we're bringing the most talented students in California to address the world’s most pressing issues. Participants are able to build projects that address many social good initiatives.



- You must submit a 2 minute video demo for your project.

- Maximum of four people per team.

- Your project must be completed entirely in the designated hacking window. You cannot work on your project before hacking begins (which is officially 11:00 AM PT on Saturday, April 16th, 2022).

- You must submit your project by 11:45 AM PT on Sunday, April 17th.

- You cannot steal another team's code in any way, shape, or form.

Best Pantry Hack

Swag Bag and Snack Baskets for each member of the winning team

The ASUCD Pantry provides UC Davis students, staff, and faculty with free groceries, but there are many other ways to receive basic needs support whether it’s through community organizations or government-provided services. With so many options it can be challenging for an individual to be informed about what services are available and how to obtain them. What are some better ways to organize this information and get it out to the community?

Best CoolDavis Hack

Hydroflasks for each member of the winning team

Cool Davis has no way currently to encourage local community members to engage with sustainability actions from our Cool Solutions webpage on a super convenient platform that allows them to choose, track, and interact. The Cool California Calculator is an action tracking platform we could share with our community, but it does not allow us to make any changes to the actions and it does not allow us to connect with the users who participate. The Community Climate Solutions program is also a great model but is not free. Community needs are constantly changing and Cool Davis programs must be dynamic and responsive to make a difference. How can all of this be combined into a usable mobile app that can be used by the community?

Best Greenhouse Hack

Amazon Kindles for each member of the winning team

The GreenHouse has a library for reading with books for 1st - 12th graders. All readers are assessed for reading levels 2-3 times a year and there are some books matched to their reading level. But the majority of the library is not evaluated for reading levels by book. How can a system to analyze books and categorize them by reading level be created?

Best Yolo Food Bank Hack

Snack baskets for each member of the winning team

With the large volume of food that the Yolo Food Bank receives, sorting them out and finding their nutritional information can be a long and tedious process. How can this be made more simple for the Yolo Food Bank?

Cryptocurrency logo

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 blockchains like Avalanche or Solana cost $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/or 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!
