The Ethereum Foundation Just Lost Its Second Co-Executive Director

Hsiao-Wei Wang has resigned from the Ethereum Foundation, effective immediately.

The departure leaves the foundation behind the second-largest crypto asset by market capitalization without either of the two co-executive directors it installed last year.

CoinGecko’s June 18 market data ranked Ethereum second by market cap, which keeps a story about EF leadership squarely inside the major-asset conversation.

Wang announced the decision herself, saying her sabbatical gave her room to think about what she wanted next.

After my sabbatical, I have decided to step down as co-executive director and board member of the Ethereum Foundation ( @ethereumfndn ), effective today. That time gave me space to reflect on my priorities and the kind of life I want to build next.

During my break, Bastian…

CoinDesk reported on June 18, 2026 that Wang stepped down as co-executive director after returning from her sabbatical.

Her exit follows the earlier resignation of fellow co-executive director Tomasz Stanczak. That means both halves of the leadership pair named in 2025 are now gone.

CoinDesk reported that Bastian Aue helped oversee the transition while Wang was on sabbatical and has now taken on a larger interim role.

The same report counted at least eight senior figures who have left the foundation over the past five months, against a backdrop of scrutiny over governance, strategy, and leadership.

Wang is not a peripheral name in this ecosystem. She came up through Ethereum research and put real work into the consensus layer that the network runs on today.

The Ethereum Foundation announced on March 1, 2025 that Wang and Stanczak would become co-executive directors effective March 17, 2025.

The foundation described Wang’s research background at the time, noting she had served as a core EF researcher for seven years and contributed to the Ethereum beacon chain.

Days later, the Ethereum Foundation board update on March 9, 2025 said Wang had also joined the board alongside Aya Miyaguchi, Vitalik Buterin, and Patrick Storchenegger.

So Wang is stepping back from both seats at once, the executive role and the board role she took on at the same moment.

Buterin responded publicly and warmly.

.@hwwonx has been a steadfast contributor to the Ethereum ecosystem for a decade. I still remember her early days in the Ethereum research community, first outside the Foundation and then inside it, and the thought and care she put into making Ethereum research and consensus work…

He credited Wang as a steadfast contributor to the Ethereum ecosystem for a decade, recalling her early days in the research community before she joined the foundation.

Nothing in Wang’s post or Buterin’s reply points to a forced exit. She framed it as a personal decision about priorities and the life she wants to build.

The harder reality is structural. The 2025 plan was to share the top job between two directors with complementary strengths, and that structure has now lost both people it depended on inside roughly a year.

Aue is holding the line on an interim basis, but the foundation has not laid out what its permanent leadership looks like from here.

For a network this size, with this much value and developer activity riding on it, the open question is what EF’s governance and strategy settle into next. The people steering the largest smart-contract ecosystem are important to watch, and right now the chair at the top is empty again.

CoinGecko provides the market-rank context.

CoinGecko’s June 18 market data ranked Bitcoin first and Ethereum second by market capitalization.

That keeps bitcoin derivatives, Bitcoin treasury financing, and Ethereum Foundation leadership inside the major-asset lane.

The ranking is context, not an investment signal.
