The departure adds another chapter to the Ethereum Foundation’s turbulent governance period, which has seen multiple leadership changes since early 2025.
What Happened
He described his remaining time at the organization as more stewardship than execution. Before joining the foundation, Stańczak was the founder and chief executive officer of Nethermind, one of Ethereum’s major execution clients.
What Stańczak Said He Accomplished
In his blog post, Stańczak listed faster internal decision-making, treasury policy development, clearer compensation guidelines, and more open institutional engagement among his achievements.
He also pointed to two network upgrades delivered in 2025 and a forthcoming merged LEAN Ethereum and core development roadmap for 2026.
The foundation also built out a post-quantum security track and launched a decentralized AI team, according to the post.
Why It Matters
The Ethereum Foundation has now cycled through two top executive structures in under 12 months. Aue’s appointment as an interim co-ED – not a permanent one – leaves the question of long-term leadership unresolved.
Stańczak said he plans to remain active in the Ethereum ecosystem as a core developer, focusing on what he called “delegated core development and delegated governance.” He said he would take questions at ETHDenver and in upcoming podcast appearances.
Ether was trading near $1,950 at the time of writing, down roughly 40% from its August 2025 all-time high near $4,950.
