Hedera AI x Hackathon
September 19, 2025
Remote
Over several high-energy weeks, the Hedera x AI Hackathon brought together builders from around the world to explore the intersection of decentralized infrastructure and artificial intelligence. Organized by the Hedera Foundation and Hashgraph, the program attracted:
- 300+ registered agents on testnet via moonscape.tech
- 500K+ livestream views across Hedera x AI channels
- 300+ hacker sign-ups
The hackathon culminated in a global Demo Day featuring live remarks from Hedera co-founders Dr. Leemon Baird and Mance Harmon, and a judging panel including leaders from Outlier Ventures, Headstarter, Genfinity, Hashgraph Online, Algorand, Hivemind, and more.
SpaceDev proudly took 2nd place with “Contracts Auditor”, an AI Agent designed to audit smart contracts in real time and display results directly on-chain. By integrating micro-payments via HIP-991, the tool ensures security audits are not only automated and affordable, but seamlessly integrated into developer workflows.
This milestone wouldn’t have been possible without:
— Santiago Grangetto, who led development and managed the live defense
— Joaquín Ferreira, who contributed key technical components
— Brenda Gutiérrez, who delivered a sharp, polished presentation on Demo Day
