Fired Employee Sues the Ethereum Foundation and Vitalik Buterin

Kayleen Fulton, who facilitated Ethereum’s core developer calls, has sued the Ethereum Foundation and Vitalik Buterin, alleging she was fired 13 days after disclosing a cancer diagnosis and 12 days after sending a staff letter about the foundation’s new Mandate. The suit adds a legal and governance dispute to the nonprofit behind Ethereum, the second-largest crypto network by market value. It matters because the case tests how the foundation handles internal dissent and employee protections as it reshapes its mandate under Buterin’s influence. Watch for the foundation’s response, any court filings detailing the termination, and whether the dispute affects the pace and tone of Ethereum’s core developer coordination.
