[A user used the MEV robot to flash loan $12 million for arbitrage, but only made a profit of $20] On September 6, according to Arkham monitoring, a user used the MEV robot to flash loan $12 million for "sandwich" attack arbitrage activities, during which a total of 14 transactions were made, but when the attack ended and the Gas fee was paid, the user only made a profit of $20. Note that a "sandwich" attack occurs when the attacker sandwiches the victim's transaction between two of his own transactions to manipulate the price and profit from the user.
