The Ethereum Foundation is facing a federal lawsuit after former employee Kayleen Fulton accused the nonprofit and several executives, including co-founder Vitalik Buterin, of wrongful termination, disability discrimination, and retaliation. The complaint was filed on November 4, 2026 in the U.S. District Court for the District of Colorado.
The dispute centers on the Foundation's 2026 Mandate, published March 13, which outlined priorities known as CROPS: censorship resistance, open-source development, privacy, and security. However, a section titled “Source Seppuku License” included language describing suicide by sword as a consequence for failing to uphold commitments. Employees objected; Fulton and colleague Trent Van Epps organized a letter signed by 53 Protocol cluster members. The complaint says 79 employees voted to remove the passage, but it remained in the published document and was permanently recorded on Ethereum's blockchain.
Fulton says she disclosed an ovarian cancer diagnosis on March 24, 2026 and was terminated on April 6, less than two weeks later. The lawsuit claims the Foundation failed to provide medical leave information or discuss accommodation. A termination call allegedly acknowledged her strong performance and support from colleagues.
The case follows a restructuring announced June 23, 2026, under which 54 employees, roughly 20% of the workforce, left the Foundation. The organization introduced five operational clusters covering protocol development, access, user experience, community engagement, and institutional adoption.
The complaint also names Stiftung Ethereum, Ethereum Asia Pacific Limited, Bastian Aue, and two employment-service companies as defendants. It quotes a May 1 conversation with Buterin in Norway that Fulton partially recorded without his knowledge. Buterin discussed concerns about rewarding employees for “making a stink” that could encourage similar attempts to influence decisions. The complaint requests a jury trial and challenges a separation agreement Fulton says she signed under duress.
None of the allegations have been adjudicated. The legal impact concerns Foundation governance and employment practices rather than Ethereum's protocol, but it adds scrutiny while the organization redefines its mission and structure.
