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.

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. 🌍

🏅 5th Place: LeekWallet LeekWallet DIY HardwareWallet is a low-cost, open-source hardware wallet that independently verifies and signs crypto transactions.

🏅 4th Place: Passport Agent Protocol Passport Agent Protocol provides a secure authorization layer for AI agents. Instead of giving agents private keys or unrestricted credentials, humans can grant scoped and expiring permissions that are enforced onchain, allowing agents to make payments and access resources while keeping control with the user. 👨‍💻 Built by: Cristobal Valencia 🔗 Check the demo: devfolio.co/projects/passpor…

🏅 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. 👨‍💻 Built by: Zhenru Yan, Ashley Zhu,@Zyy0530 🔗 Check the demo: devfolio.co/projects/selfhea…

🏅 2nd Place: VitaPod VitaPod enables patients to prove their eligibility for clinical trials without revealing sensitive health data. Using zero-knowledge proofs, it verifies eligibility criteria such as age and biomarkers locally, allowing sponsors to confirm eligibility without accessing the underlying medical information. 🧑‍💻 Built by: Mariana Uchoa, Diana Chang, @mehdiloup_eth 🔗 Check the demo: devfolio.co/projects/vitapod…

🏅 1st Place: Lattice Studio Lattice Studio is a visual development tool for building and validating EIP-2535 Diamond contracts. It helps developers compose facets, check selectors, storage, dependencies, initialization, and upgrade authority in real time, catching potential issues before deployment. 👨‍💻 Built by: David Dada 🔗 Check the demo: devfolio.co/projects/lattice…

🏆 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🧵:

Thanks to every builder who joined us and shipped in Sydney. 🇦🇺 The EAG 2026 Global Builders Initiative has officially wrapped up. We’re grateful to every builder, community, and local partner who joined us along the way and helped make this journey possible. 🌍 See you at this year’s @shanhaiwoo! 🇨🇳
