Hsiao-Wei Wang is gone from the Ethereum Foundation. The co-executive director and board member confirmed the departure on Thursday, effective immediately, after a sabbatical that ended with a decision she said she had been working toward for some time.
The exit lands differently than most leadership changes at the EF. Wang did not just hold a title. She took the co-executive director seat in March 2025 during one of the most disorganized stretches in the Foundation’s history, then continued operating as primary ED after Tomasz Stańczak left in February 2026, working alongside interim co-executive director Bastian Aue, who had been guiding the transition during her leave.
As Hsiao-Wei Wang posted on X:
“After my sabbatical, I have decided to step down as co-executive director and board member of the Ethereum Foundation, effective today. That time gave me space to reflect on my priorities and the kind of life I want to build next.”
That sentence does a lot of quiet work. It does not name a conflict. It does not describe tension. But it arrives after a leadership churn that has quietly stripped the EF of a significant portion of its senior layer.
One Role, Two Jobs, No Playbook
Wang joined the EF research team in mid-2017. Her early work covered sharding proofs-of-concept and consensus mechanisms, and she was part of the group that helped design the Beacon Chain, the infrastructure Ethereum’s proof-of-stake transition later depended on.
That technical foundation mattered when she moved into the executive seat. She was not a communications hire. She was a researcher who understood what the protocol actually needed, which made her read of organizational priorities different from most people in that chair.
Vitalik Buterin put it plainly in a post on X:
“She handled the task skillfully and gracefully, and has constantly strived to find and insist on outcomes that are right both for the Ethereum protocol and for the human beings that build and maintain it.”
The acknowledgment matters. Buterin does not often weigh in on personnel matters with that level of specificity.
The Beacon Chain work she helped complete did not happen in isolation. It required years of coordination across researchers, client teams, and external contributors, and Wang was embedded in that structure long before she moved to the top of it.
What Bastian Aue Inherits
The EF’s leadership layer is now noticeably thin. Stańczak left in February. Two of the three Protocol cluster heads, Barnabé Monnot and Tim Beiko, have departed. The third, Alex Stokes, announced a sabbatical. Josh Stark resigned in March after seven years with the organization.
Wang spent her sabbatical knowing Bastian Aue was managing the transition.
She credited that directly: “During my break, Bastian guided the transition with care and thoughtfulness, and I appreciate the work he and many others have put into that process.”
Aue’s background spans grants, enterprise coordination, and organizational strategy inside the Foundation. He is not a protocol researcher. That distinction is worth watching as the EF tries to hold technical continuity while rebuilding its management structure.
ETH was trading near $1,708 at the time of writing, down roughly 1.4% in 24 hours and sitting nearly 66 percent below its August 2025 all-time high of $4,946. The price context does not cause leadership exits, but it does shape how they land externally.
The Protocol Does Not Wait
For an ETH holder watching this, the operative question is not whether Wang’s departure signals something dark about Ethereum. It is whether the people now left inside the EF can maintain the research coordination and external credibility the network depends on at the application and consensus layer.
Wang’s answer to that question was the same one she gave throughout her tenure.
“Ethereum has always been bigger than any one role, any one organization, or any one moment. Its strength comes from those who keep building permissionless infrastructure across the ecosystem to unlock freedoms that didn’t exist before.”
She said her next steps are not finalized. She expects to spend more time closer to home. She described herself as a proud member of the community going forward, whether inside or outside the Foundation.
The EF has not announced a replacement or a revised structure. Aue holds the interim position. What that looks like in six months is not yet clear.
Wang’s own framing of her decade was less about title and more about what the work produced.
“What I will remember most is the people behind the work. We come from different places, speak different languages, and build different things. But the purpose that brought so many of us here remains the same: building a world that no one can shut down, making systems more open, resilient, and more access to anyone, anywhere.”
That last clause is slightly off, grammatically. She left it that way. The point still lands.
