Account Abstraction is becoming one of the most transformative topics in the Ethereum ecosystem. The introduction of EIP-7702 marks a pragmatic and visionary step forward in this domain.
We believe that meaningful innovation doesn't always come from boardrooms or conference stages — it often starts with a late-night hack or a sudden spark in your code editor.
Bring your creativity, code, and maybe a cup of iced coffee — and help shape the next chapter of Account Abstraction.
- Open registration: 1-6 Jun. Learn from repo (or add more docs, ideas, examples!) + pop-up workshops
- Open Day: 6 Jun. Deep-dive 7702, Q&A, team match
- Hacking: 6 Jun - 8 Jun. Couch-friendly hacking weekend

EIP-7702 addresses key limitations of EIP-3074 while preserving its core strength: temporarily turning EOAs into smart accounts.
Key benefits:
- ✅ Backwards-compatible (works alongside ERC-4337)
- ✅ Highly extensible (supports custom validation logic)
- ✅ Improved security model (avoids permanent delegation risks)
This isn't just a fix — it's a new design space for wallets, dApps, security, identity, and permissions.
Now is the time to build, test, question, and innovate — hands-on, from the ground up.
