Kayleen Fulton, previously chief of Protocol Support at the Ethereum Foundation, has filed a lawsuit against the Foundation and its co-founder Vitalik Buterin, alleging wrongful termination tied to protests against a controversial employment mandate and discrimination surrounding her cancer diagnosis.
Details of the lawsuit
Filed in Colorado federal court on November 4, the complaint names six defendants: Stiftung Ethereum (the core foundation based in Switzerland), Ethereum Asia Pacific Limited (a Singapore affiliate), payroll firms Lightsource HR Global and Vensure Employer Services, co-executive director Bastian Aue, and Vitalik Buterin.
Fulton, also known as “Nixo,” contends that she lost her job after challenging an internal mandate that included a so-called “suicide pledge” clause and after disclosing her diagnosis of ovarian cancer. The lawsuit does not address Ethereum blockchain operations, focusing solely on employment-related decisions and practices inside the organization. Claims within the lawsuit have not yet been established in court.
The ‘suicide pledge’ controversy
The March 13 employment mandate released by the Ethereum Foundation set out principles regarding censorship resistance, open source, privacy, and security. One controversial clause, called the “Source Seppuku License,” described software developers metaphorically committing suicide with swords if they failed to uphold these principles.
Before the official publication, employees reportedly protested this element. According to the complaint, 79 staff members voted to remove the “suicide pledge” clause from a draft in February, yet the Foundation kept it in the final document. Later, co-executive director Bastian Aue clarified that the language should not be taken literally, but staff were ultimately required to accept the mandate or leave the organization.
Co-executive director Bastian Aue stated that the clause in question “should not be taken literally,” but employees had no alternative but to either accept the mandate or resign.
Termination following cancer disclosure
On March 24, Fulton notified the Foundation of her cancer diagnosis. She, alongside Trent Van Epps, wrote a letter supporting the Foundation’s broader direction but opposing forced agreement with the “suicide pledge.” The letter was endorsed by 53 other employees, all of whom kept their positions. However, on April 6, both Fulton and Van Epps were dismissed by Bastian Aue.
Fulton argues that her termination amounted to retaliation, citing her rights under the Americans with Disabilities Act and laws protecting medical leave. She claims she did not voluntarily sign her separation agreement and seeks compensation for lost wages and additional damages. Whether her illness directly influenced her firing remains unresolved.
Fulton maintains that her firing constituted retaliation for protest activity and that she faced disability discrimination after revealing her ovarian cancer diagnosis.
Recorded conversation with Buterin
Fulton included in her filing a partial recording of a May 1 conversation with Vitalik Buterin in Norway. She asserts that Buterin questioned whether granting special reward to employees who raised complaints might set an unwanted precedent, which she interprets as evidence of retaliation. No legal responsibility for Buterin or the Foundation has been determined based on these statements.
Leadership turmoil and funding concerns
Fulton’s lawsuit points to further turnover in the organization. By September, at least eight senior staff had departed, including co-executive director Hsiao-Wei Wang, who left in June after earlier taking leave. A July update listed only four directors, including Buterin. Ongoing departures have caused concern over stability, with Trent Van Epps estimating that $30 million per year is needed for core development teams as the Foundation’s spending has decreased.
Broader impact on institutional sentiment
The Foundation’s leadership changes have drawn attention from institutional investors. A CoinShares survey in August linked slower Ether growth projections partly to uncertainty at the Foundation. Separately, an EY survey showed that 81% of investors holding spot cryptocurrency favored ETFs or similar investment products over direct exposure.
Recent data from Farside indicate that between November 2 and 6, US spot Ether ETFs experienced net outflows totaling $365.2 million. The only positive movement was a $53 million inflow on November 4, but broad outflows occurred across the rest of the week. These trends largely predate the lawsuit and coincide with broader market volatility, with no direct connection to the legal dispute currently established.
Ongoing changes inside large crypto organizations can impact both market confidence and asset flows.
