ETHIstanbul 2025 marked a turning point as a global gathering place for Ethereum builders in Istanbul.

Over three days (Sept 5–7) at the historic Rami Library, builders, hackers, and researchers from across the world came together to create, collaborate, and showcase the future of blockchain.

This year, ETHIstanbul became the hub where global protocols met Türkiye’s developer talent, proving that İstanbul has the capacity to serve as a long-term global center for Ethereum innovation.

Our commitment is simple: “everything = community impact.”
