HACK4GOOD: Building on the XRP Ledger

XRPL Commons and the engineering school ECE Paris are joining forces to launch Hack4Good XRPL & ECE Sustainable Solutions, a hackathon dedicated to addressing social and environmental challenges through blockchain technology.

Over the course of two intensive days, participants will have the opportunity to design innovative, engaging, and playful solutions while aiming for real-world impact on concrete issues. Experienced mentors will guide the teams, and the diversity of participants will foster synergies and original ideas.

We encourage everyone to think outside the box, combining social utility, environmental impact, and playful elements to make their solutions both meaningful and captivating.

This event is open to all, whether you are a student, professional, or blockchain enthusiast.
