Pi Network has launched Pi Hackathon 2025, the first community-wide hackathon since the launch of Open Network! Developers are invited to build Mainnet apps that empower real-world utility using Pi and help shape the ecosystem—and compete for a chance to win up to 160,000 Pi in total prizes.

Register now, form a team, and submit a working app, demo video, and the required forms by Oct 15. Go to the Pi Developer Portal and use the invitation code “hackathon25” to get started!
