The gist
Former Ethereum Foundation staffer Kayleen Fulton sued the nonprofit, alleging she was fired after opposing a suicide pledge.
The case tests how far a crypto nonprofit's internal mandate can go.
Background
Stiftung Ethereum (the Ethereum Foundation) is a Switzerland-registered nonprofit supporting Ethereum, the blockchain network. In 2026 it circulated a 38-page mandate outlining leadership's vision for the next 1,000 years, which included a 'Source Seppuku License' pledging covered people to 'take his or her own life with a sword' if they failed to uphold pledges or if the license was modified or removed. Kayleen Fulton, the foundation's former Protocol Support lead and a Boulder, Colorado resident, is now suing the foundation, co-founder Vitalik Buterin and others in federal court in Colorado, alleging wrongful termination and discrimination.
How it unfolded
- Feb 2026The Ethereum Foundation distributed a draft mandate to employees including the 'Source Seppuku License' suicide pledge.
- Mar 2026The 38-page document went to all employees, who were told to commit to the principles by Monday or quit.
- Mar 2026About 79 employees voted to remove the clause; leadership kept the pledge word-for-word in the final mandate, shown in an illustration rather than the main body.
- Mar 2026Fulton and colleague Trent Van Epps sent the board a letter signed by 53 members of the Protocol cluster declining to affirm the mandate under coercion and stating signers had not resigned.
- Nov 5, 2026Protos reported Fulton's lawsuit against Stiftung Ethereum, Vitalik Buterin and others, alleging she was fired after disclosing a cancer diagnosis and organizing opposition to the pledge.
- Nov 6, 2026The Denver Post reported the suit, filed in federal court in Colorado, alleging wrongful termination and discrimination.
- Nov 7, 2026Reports detailed claims of disability discrimination, retaliation and FMLA interference; Fulton's annual salary was $195,000 per the complaint.

Who’s saying what
- Party
- Fulton alleges she was fired after disclosing a cancer diagnosis and organizing opposition to the suicide pledge, and the complaint claims disability discrimination, retaliation and FMLA interference.
- Official
- Per the lawsuit, Co-Executive Director Bastian Aue told employees those who did not commit to the mandate would be presumed to have resigned, and described the pledge as part of the mandate's artwork; managers said the commitment form had 'nothing to do with literal seppuku.'
- Caution
- Per the complaint, Vitalik Buterin said the firing was about company dynamics rather than the diagnosis and, in a recorded conversation, reportedly said rewarding people for making a stink would teach employees to use displays to cause outcomes.
Still unverified
The foundation's side is not represented in the sources; an email seeking comment was not immediately returned. Buterin's alleged remarks are described as coming from the complaint and a recorded conversation.
