Translation of the body content: Co-founder of Ethereum, Vitalik Buterin addressed the public's concerns regarding his recent sale of ETH on social media. He explained that this sale was initiated by an organization focused on bio-defense, with the goal of supporting research and development in related fields. This action was executed through an automated CoWSwapTWAP order set since August 29th, designed to distribute trades during a specific timeframe in order to minimize market price fluctuations and secure holdings at an average market price. The TWAP order function introduced by CoW Swap offers traders an efficient method to achieve more stable market pricing and optimal trading results by evenly allocating trading volume over a period of time.
