ETH Foundation loses another senior executive

TLDR

Ethereum Foundation co-executive director Hsiao-Wei Wang has resigned, adding to a string of senior departures this year and intensifying debate about the foundations leadership and funding.

1. Wang stepped down as co-executive director and board member, becoming at least the eighth senior Ethereum Foundation exit in recent months.
2. The departures coincide with warnings of a roughly $30 million annual funding gap for core development, while some large stakeholders insist a funding crisis is unlikely.
3. Key signals now are how governance is restructured, how core developer funding evolves, and whether protocol upgrade velocity or network reliability show any stress.

Deep Dive

1. What Just Happened

Hsiao-Wei Wang, co-executive director and board member of the Ethereum Foundation (EF), has resigned after a sabbatical, as confirmed in reports from CryptoPotato and The Defiant. She joined EFs research team in 2017 and helped lead major milestones such as the Beacon Chain, The Merge, Shapella and Dencun upgrades. Her exit follows the departure of fellow co-executive director Tomasz Sta?czak in February and several other senior figures, making Wang at least the eighth senior leader to leave EF in roughly five months according to multiple outlets.

Board member Bastian Aue, who helped manage the transition during her sabbatical, is described as effectively the sole executive director in the interim. Vitalik Buterin publicly praised Wangs contributions and framed the co-executive director role as one of the most demanding positions at EF.

2. Funding And Governance Concerns

Former EF contributor Trent Van Epps has warned that EF spending cuts and the end of the Client Incentive Program could create a slow-burning funding crisis for core developers, estimating annual needs around $30 million for client teams and researchers. Articles note at least eight senior departures, including Van Epps himself, which he links to tightening funding and organizational changes at EF.

In response, BitMine chairman Tom Lee, whose firm holds over 5 million ETH, has argued there is zero chance of a developer funding crisis and that staking economics and initiatives like Protocol Guild can fill any gap. EF has also said its treasury plan keeps it solvent in the medium term and has framed downsizing as part of a deliberate shift to a smaller, more focused foundation rather than a collapse.

3. What To Watch Next

There are three practical things to track:

1. New leadership structure: Whether EF names new co-executive directors or formalizes a leaner governance model centred on figures like Aue and Buterin.
2. Core dev funding model: Progress on Protocol Guild and any successor to the Client Incentive Program, plus signals that independent teams have stable, multi-year budgets.
3. Technical roadmap execution: Timing and quality of upcoming upgrades (for example, post-Dencun roadmaps) as a proxy for whether talent loss is affecting shipping velocity or network reliability.

Conclusion

Ethereum Foundation losing another senior executive confirms a real leadership reset at the organization, overlapping with a contentious shift in how core development is funded. The key question is whether a more decentralized, stakeholder-driven funding model can sustain protocol work without EF carrying as much of the load, and the answer will show up in how smoothly Ethereum continues to ship upgrades and maintain network robustness over the next year.
