On July 9th, GMGN co-founder Haze posted on X, stating, "There have been malicious nodes sandwiching people, and Jito's services are also unstable. Starting today, if users use GMGN and enable MEV (anti-sandwich), and are still sandwiched, please send the Hash to the official staff. If it is verified that MEV was enabled and the user was still sandwiched, the official will compensate the corresponding fees." [Deep Tide TechFlow]
