BlockBeats News, July 9th, GMGN Co-founder Haze published a post on the X platform stating that there has been a recent malicious "Sandwich Attack" phenomenon and the Jito service has become unstable. Starting today, if users still fall victim to sandwich attacks after enabling GMGN's MEV anti-sandwich feature, they can submit the transaction hash to official personnel for verification. Once confirmed, they will receive corresponding fee compensation.
