Launching the Ethereum Applications Guild (EAG)
The Ethereum Applications Guild (EAG) is being launched as a global non-profit collaborative organization supporting the Ethereum application ecosystem.
As the Ethereum ecosystem reaches a new level of infrastructure maturity, the focus is increasingly shifting toward the application layer. EAG aims to support this transition by advancing the innovation, adoption, and real-world impact of Ethereum-native applications.
🏆 After more than two months of building, we’re excited to announce the winners of the EAG Global Buildathon (Online).
Some projects had previously joined our IRL hackathons and continued to build and improve, while others joined online and stood out with what they built.
Here are the 5 winning projects🧵:
🏅 5th Place: LeekWallet
LeekWallet DIY HardwareWallet is a low-cost, open-source hardware wallet that independently verifies and signs crypto transactions. It keeps private keys off host devices, supports air-gapped QR signing, and is designed to make hardware wallet security accessible, reproducible, and fully auditable.
👨💻 Built by: Oucan Oucan

The EAG Global Buildathon comes to a close. Thank you to all the sponsors, communities and builders who joined and supported us along the way. 🩷
All 5 winning projects will be invited to join the @shanhaiwoo GBA starting October 15.
Looking forward to more building and collaboration as we come together in Shenzhen, Mumbai & Hong Kong. 🌍
🇦🇺 The Ethereum Hackathon @ Sydney has come to a close!
In just one day, builders came together to turn ideas into working applications and bring them onchain.
Here’s what they built 🧵👇
🥉 HSK Chain 3rd Place: Self Healing Honeypot
Self-Healing Honeypot is a security framework for AI agents that continuously tests, detects, and fixes vulnerabilities. It uses incentivized attacks and deterministic verification to turn real exploits into targeted patches and regression tests.
