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.
