Ethereum Foundation Faces Lawsuit Over Wrongful Termination and Controversial Suicide Pledge
Former employee Kayleen Fulton alleges disability discrimination and retaliation following a staff-led protest.
1Federal Lawsuit Filed
Kayleen Fulton, former Protocol Support lead, filed a federal lawsuit against the Ethereum Foundation and Vitalik Buterin. The complaint alleges wrongful termination, disability discrimination, and medical leave violations. Fulton, who earned $195,000 annually, was dismissed on April 6, 2026, shortly after disclosing an ovarian cancer diagnosis to senior management.
2The 'Source Seppuku' Mandate
The dispute centers on a 38-page organizational document distributed to 250 employees in February 2026. Page 11 included a 'Source Seppuku License,' requiring contributors to pledge they would take their own lives with a sword if they failed to uphold the license terms. The foundation later claimed this was merely artistic.
3Widespread Internal Resistance
The mandate sparked significant friction, with approximately 79 staff members voting to remove the suicide pledge. Despite management promising changes, the final March version retained the controversial language as a stylized illustration. Fulton and colleague Trent Van Epps organized a protest letter signed by 53 employees opposing the mandatory endorsement.
4Targeted Retaliation Allegations
Fulton claims she was selectively targeted for organizing the protest letter. The lawsuit cites a recorded conversation where Vitalik Buterin questioned whether rewarding employees for challenging management would encourage further dissent. By September, eight senior employees had left, and most of the 53 signatories were either terminated or resigned.
5Medical Leave Violations
Fulton disclosed her ovarian cancer diagnosis on March 24, 2026, just 13 days before her termination. The lawsuit asserts that the foundation interfered with her rights under the Family and Medical Leave Act. Management allegedly failed to address her requests for employment protection or leave before dismissing her without a specific explanation.
6Complex Legal Defendants
The lawsuit names six defendants, including the foundation’s Swiss and Singaporean entities, executive Bastian Aue, and Vitalik Buterin. It also includes two human resources service providers, Lightsource HR Global and Vensure Employer Services. Fulton is challenging the enforceability of a separation agreement that requires arbitration in Singapore and waives legal claims.
7Regulatory and Legal Status
Fulton has filed 11 legal claims in the U.S. District Court for the District of Colorado. She previously filed a discrimination charge with the Equal Employment Opportunity Commission, receiving a right-to-sue notice in September. An unfair labor practice charge remains pending with the National Labor Relations Board regarding her workplace dismissal.
8Governance and Future Implications
This case highlights deep governance friction within the decentralized organization. The transition from a collaborative environment to a mandate-driven structure created significant internal instability. As the litigation proceeds, the foundation faces scrutiny over its employment practices and the potential legal consequences of enforcing controversial mandates on its global workforce.
