ETHGlobal has announced 10 finalists from its Cannes 2026 hackathon, with projects heavily focused on AI agent security, privacy infrastructure, and on-chain prediction markets. The finalist lineup demonstrates the maturation of autonomous agent technology in the Ethereum ecosystem, with several projects addressing critical security and operational challenges.
ENShell, developed by CodeQuillClaim, addresses a crucial security gap by preventing AI agents from executing malicious transactions caused by prompt injection attacks. The project wraps agent transaction flows in a hardened ENS-aware shell that validates proposed actions against policy before any wallet signatures occur. This represents a significant advancement in AI agent security infrastructure.
DIVE introduces an AI swarm engine for verifying real-world truth in prediction markets with autonomous on-chain settlement, while Corpus focuses on giving agents specific operational roles and guardrails. These projects collectively show how autonomous agents can safely sign, verify, and trade on-chain while maintaining security and reliability standards essential for mainstream adoption.
