CDR Hackathon
Build apps that use private data without giving up composability.
The CDR Hackathon is a focused virtual event for developers exploring a new primitive powered by Story’s Confidential Data Rails: programmable private data onchain.
Instead of hiding sensitive data entirely offchain, CDR lets developers create encrypted objects with dynamic access control, composable permissions, and verifiable compute.
Build things like:
Private AI agents with encrypted memory
Data marketplaces and subscription access
Confidential order books and coordination systems
Medical, identity, or financial apps with programmable privacy
Autonomous onchain objects with private state
Completely unhinged experiments nobody has thought of yet
There will be $3,000 in prizes spread across 3 winners.
May 27 → June 5
Virtual Hackathon
Open to developers worldwide
