EigenPhi: The amount of sandwich attacks in the past month has exceeded 17 billion US dollars

On August 20th, the MEV tracking website EigenPhi reported that the amount of sandwich attacks in the past month has exceeded $17 billion. At the same time, a new type of MEV contract has emerged which adopts new strategies and more complex multi-layered sandwich attacks against DeFi protocols - it arranges transactions before and after victim's transactions to manipulate prices and profit from victims. This bot is an automated trading system that exploits vulnerabilities in DeFi protocols for profit. Its new attack involves executing multiple transactions within the same block to manipulate exchange rates in Uniswap V3 pools, allowing the bot to profit at other users' expense.
