Per Woofun AI, Hsiao-Wei Wang resigned as Ethereum Foundation co-executive director effective Thursday, leaving both co-executive director positions vacant following Tomasz Stańczak’s earlier departure. This marks the eighth senior exit in five months, intensifying scrutiny on governance and leadership stability. Wang, who joined the research team in 2017, cited a sabbatical for reassessing personal priorities after becoming co-executive director in April 2025.

Bastian Aue has assumed an interim executive director role amid this transition. Recent departures include Josh Stark, Trent Van Epps, Tim Beiko, Barnabé Monnot, Carl Beek, and Julian Ma, key figures in Ethereum research and engineering. Community discussions now focus heavily on governance, spending priorities, and organizational structure. Vitalik Buterin praised Wang’s decade-long contributions to consensus development and major upgrades like The Merge and Dencun, while developer Marius Van Der Wijden acknowledged her support during challenging protocol development periods.
