Analyst: A certain address front-ran Zhao Changpeng's on-chain transaction but was then hit by a trap, ultimately leading to the failure of Zhao Changpeng's transaction
ChainCatcher message, according to crypto analyst @shoucccc, Zhao Changpeng's first TST purchase transaction was sent via a privacy RPC, but the transaction information was still leaked.
Zhao Changpeng's transaction set a minimum purchase amount of 363,225 TST, but due to blockchain slippage, he actually received 365,564 TST, a difference of about 0.7%. If the transaction had not used a privacy RPC, it could have resulted in profits worth over $200 being earned by a "sandwich bot." A certain address front-ran Zhao Changpeng's transaction but was then hit by a sandwich, ultimately causing Zhao Changpeng's transaction to fail.
Additionally, the address (0xB2d57876271eA8684e7c521c1265b87703d9A0DA) seems to have known about Zhao Changpeng's buy order in advance and attempted to backrun Zhao Changpeng's transaction by checking his TST balance. @shoucccc believes that this address is not a sandwich address and has not previously traded against Zhao Changpeng.
