🥪 Jupiter solves sandwich attack on Solana chain? I saw a tweet from Jupiter Lianchuang @ weremeow stating that users who traded in Jupiter Ultra mode for the past 7 days did not make any sandwich attack transactions. I am surprised and curious about his statement and data. First, let's take a look at how they miraculously solved this long-standing MEV problem. According to the cited tweet (see screenshot), the method they used may seem strange, but it was very effective: Forcefully adding Jupiter Vote Account voting account to the list of initiating transactions will result in Jito engine refusing to package such transactions. And Jito Bundle packaging multiple transactions is precisely the foundation for the realization of MEV (bot buying to raise prices, victim swap trading, bot selling to profit are typical paths of sandwich attacks) 💡 Unexpected solutions. Let's take a look at the sandwich attack data on the platform Sandwiched Dot Me. Here is the 30 day view: The Jupiter platform has the highest proportion of trading volume; According to Telegram bots, the top three are: Photon、Bullx、Trojan Domestic platform GMGN ranks fourth, while Pepe Boost ranks second to last. It seems that there is a difference between the actual number of users displayed in the data and the sensory perception on the promotion. A very intuitive explanation is: What you see on Twitter is mostly Chinese content, and the probability of tools used by the Chinese user group appearing will be proportionally increased. But on the entire chain (for Solana), the absolute number of English speaking users is higher globally, but the probability of appearing on your timeline is relatively low. Typical information cocoon effect.
