On February 23, according to analysis by crypto analyst Shoucccc, 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 slippery point of the blockchain, 365,564 TSTs were actually received, a difference of approximately 0.7%. If the transaction does not use privacy RPC, profits worth more than $200 could be earned by the clip robot. An address stole CZ's transaction but was attacked by clips, which eventually led to CZ's transaction failure. In addition, the address (0xB2d57876271 eA8684 e7c521c1265b87703 d9A0DA) seems to know in advance the purchase order and try to backrun CZ's transaction by checking CZ's TST balance. Shouccc believes that this address is not a clip address and no previous transactions have been made against CZ.
