Pi Network is excited to kick off 2023 by announcing the launch of a new Hackathon! The network is building on the momentum from the 2022 College Hackathons and the 2021 Pi Hackathon, and continues to facilitate the development of quality Pi Apps. This hackathon will span until February 28, 2023. 

Over the past few years, Pi Network has built the world’s most widely distributed cryptocurrency with over 35 million members across the globe, and the necessary ecosystem infrastructure. In 2023, as part of the mission of growth and utilities-building during the current Enclosed Network period of Mainnet, the network is continuing to expand and improve its app platform. This is to enable more community development and collectively become an even more robust utilities-based ecosystem. 

That’s where you come in: Pioneers and developers like you are encouraged to contribute to Pi Network and ecosystem growth by building mobile web apps that bring true utility to the users. We’re looking for creative, utility-focused apps; these could be entertainment, education, social interaction, access to information, consumer utilities, or anything else you can think of. 

Read on for more hackathon details, including the challenge and prize information; important onboarding, team formation, and project submission instructions; and helpful resources as you begin to develop!

The Challenge

Pioneers and developers are invited to build mobile web apps that address a real user need, support the use of Pi cryptocurrency, and are intuitive to use and accessible to everyday people. 

Developing on Pi is easy, and doesn’t require any previous blockchain or crypto experience – simply build a mobile web app, integrate our SDK with JavaScript, and make API calls. If you want to participate in the Hackathon, follow the instructions further below  to get started! 


You may choose to focus your project on one of themes below, or choose the Open Innovation theme and create the best app you can that doesn’t fall into one of the following categories. 

  • Social Media
    • What if users could send or receive micro-payments as part of this new category of social media you are creating? What if the use of staking can bubble up the best content? What if content creators can be rewarded for great content? You can be the innovator to bring micro-transactions into social media for the first time. 
  • Games / Entertainment
    • This is the track for all things entertainment; show us your best games and entertainment apps that will keep our audience engaged in any way you can imagine. Don’t forget to integrate the Pi cryptocurrency as closely as possible to your ideas. 
  • Consumer Utilities
    • This category is for all apps that provide utilities to our members, or to other businesses. Examples may include loyalty programs for businesses that bring the power of blockchain to the masses, marketplace apps, education platforms and more.
  • Open innovation 
    • Show us your best idea – what is the coolest app you can think of?!
