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~
