/ PAIFLOW HACKATHONS

First JRU Hackathon

Our first hackathon at JRU brought students together to explore what they could build with programmable payments.

/ THE CHALLENGE

A real problem. A payment flow.

The challenge: build an app for a real user and integrate automated payments through Paiflow. Teams could prepare before the event, then use the day to finish their integration, verify a testnet payout, and present their demo.

Paiflow supplied the visual payment-flow builder and integration tools. The event focused on creativity, useful applications, and how well the payment flow served each idea.
