We just wrapped up a packed week in Cannes with the @ETHGlobal hackathon~ Here’s a quick look at the Zircuit prize winners and a few standout projects👇

The hackathon ran from July 4–6 right after @EthCC 💚 We gave out prizes in three categories: > Best project on Zircuit > Best use of account abstraction > Best app idea

🏆 Best Project on Zircuit: PrivyCycle An encrypted, AI-powered period tracker focused on privacy and user control. Data is shared securely via IPFS, with Zircuit used to log entries.

⚡ Best Use of Account Abstraction: BeamPay Payment infrastructure for ERC-20 transfers with metadata — think purchase orders or tax info onchain. Clean implementation using 7702, a custom browser plugin, and deployed contracts.

🧠 Best App Ideas (3 winners): > PhishStake: Local AI that detects phishing attempts with opt-in screenshot monitoring + blockchain-based reporting via staking. > ShowUp: Telegram bot that lets friends stake tokens to commit to events. No-shows get slashed. > Zircuit Prolog Preex: Concept for supporting Prolog as a pre-execution language on Zircuit’s zkVM.

Honorable Mentions: > OpinionMARKET: Continuous subjective prediction markets > Zkipper: Post-quantum AA with role-based permissions > Make Cat Fat & Save: Save your dust, fatten your onchain cat

Thank you to all the teams who hacked on Zircuit, we loved the creativity, thoughtfulness, and strong execution from you all~ Next stop: @ETHGlobal New York 🗽 See you soon 🐱
