A former Ethereum Foundation employee, Kayleen Fulton, sues the Ethereum Foundation and Vitalik Buterin, alleging she was fired shortly after disclosing a cancer diagnosis. Both outlets say Fulton also claims she helped organize a staff letter that challenged a new foundation mandate.

The dispute appears to center on Fulton’s internal involvement and communications around workplace expectations. One report emphasizes the timing of her termination—described as occurring less than two weeks after she disclosed her health condition—and frames the case around that disclosure and the staff letter. The other report adds that Fulton’s complaint references a recorded conversation involving Buterin and characterizes the underlying dispute as tied to a “suicide pledge,” while also alleging discrimination and retaliation.
