Haze, co-founder of GMGN, wrote on the X platform that there has been a phenomenon of malicious nodes "clamping people" recently, and the Jito service has been unstable. From today onwards, if users are still clamped after enabling the MEV anti-clip function provided by GMGN, they can submit a transaction hash to verify with the official. After confirming that it is correct, they will receive corresponding fee compensation.
