Analysis: It is possible that someone knew in advance that CZ would purchase TSST.

Odaily Planet Daily News According to @shoucccc's analysis, CZ's first TST purchase transaction was sent through a private RPC, but the transaction information was still leaked. CZ's trading has set a minimum purchase amount of 363,225 TST, but due to the slippage of the blockchain, you can actually receive 365,564 TST, with a difference of about 0.7%. If the transaction does not use private RPC, it may result in profits of over $200 being earned by "claw machine robots". An address front-ran CZ's transaction but was sandwiched, ultimately causing CZ's transaction to fail. What's even more suspicious is that the address 0xB2d57876271eA8684e7c521c1265b87703d9A0DA seems to have known about CZ's buy order in advance and attempted to backrun CZ's transaction by checking CZ's TST balance.
