Multiple reputable crypto news outlets, including a highly authoritative and directly relevant report from The Block, explicitly confirm that following Tomasz Stanczak’s resignation as co-executive director of the Ethereum Foundation, Bastian Aue was appointed to the interim co-executive director role. The report from The Block is consistent with a secondary confirmation from a Chinese-language outlet that also identifies Bastian Aue in the same capacity. There are no credible sources contradicting this leadership transition, and unrelated or low-authority sources provide no conflicting information. Therefore, the statement that the Ethereum Foundation appointed Bastian Aue as interim co-executive director following Stanczak’s departure is strongly supported by high-quality, consistent primary evidence.
