CHARLI3 ORACLES HACKATHON
Trusted by leading projects & Teams
Why This Hackathon?
Accelerate adoption of Cardano's first decentralized pull-based oracle through real-world integrations and community-driven innovation.
Cardano's only On Demand Pull Oracle exists but lacks adoption. Developers don't know how to integrate it, limiting ecosystem growth and real use-case creation.
We're accelerating adoption of our OSI Compliant Open Source pull-based oracle solution while engaging the community to improve and showcase its potential.
