According to TechFlow, on September 12, Ethereum co-founder Vitalik Buterin responded to netizens’ comments on social media, “Stop selling ETH” and said, “Yesterday’s ETH sell-off was initiated by a biodefense organization I funded and was triggered by an automatic CoW Swap TWAP order set as early as August 29. This is the last order.”

It is reported that CoW Swap's time-weighted average price (TWAP) order allows traders to spread transactions over a specified time period to smooth market price fluctuations and obtain positions at average market prices.
