On February 23, according to crypto analyst shoucccccc analysis, CZ's first TST purchase transaction was sent through privacy RPC, but the transaction information was still leaked. CZ's transaction set a minimum purchase volume of 363,225 TSTs, but due to the slippage of the blockchain, 365,564 TSTs can be actually received, with a difference of about 0.7%. If the transaction does not use privacy RPC, it may result in profits worth more than $200 being earned by the clip robot. An address snatched CZ's transaction but was hit by a clip, which eventually led to the failure of CZ's transaction. In addition, the address (0xB2d57876271eA8684e7c521c1265b87703d9A0DA) seems to know CZ's payout in advance and try backrun CZ's transaction by checking CZ's TST balance. shoucccccc believes that the address is not a clip address and has not been traded for CZ before.
