Ethereum Foundation Hit With Wrongful-Termination Suit Over April 6 Firing

2026-11-10 | COINOTAG

Kayleen Fulton, who led the Ethereum Foundation's protocol support team, has filed a wrongful-termination complaint against the organization in US federal court. The complaint was lodged on November 4 in the US District Court for the District of Colorado, according to COINOTAG's original report.

Defendants named in the filing include the Foundation's Swiss entity, its Singapore affiliate, co-executive director Bastian Aue, Ethereum co-creator Vitalik Buterin, and additional parties listed in the complaint, per COINOTAG. The action stems from Fulton's dismissal on April 6.

As with any civil complaint, the filing sets out allegations that have not been tested in court. The specific legal claims and remedies sought were not detailed in the report excerpt available at publication time, and later entries on the Colorado federal docket may clarify the claims, the remedies sought, and whether the named defendants respond.

The suit names an organization central to Ethereum's ecosystem: the Foundation is a nonprofit established in 2014 and headquartered in Zug, Switzerland, funding and supporting development of the Ethereum blockchain and its broader ecosystem. Buterin introduced Ethereum in a 2013 white paper, and the network launched in 2015. The Foundation maintains entities in multiple jurisdictions, including Switzerland and Singapore — the two units named as corporate defendants alongside the individual defendants. With the case now before a US district court while the corporate defendants are organized abroad, how venue and jurisdiction are addressed in subsequent filings may be worth following as the docket develops.
