Previously, crypto community analysis found that CZ's first TST purchase transaction was sent through the privacy RPC, but the transaction information was still leaked. CZ's transaction set a minimum purchase amount of 363,225 TST, but due to the slippage of the blockchain, 365,564 TST could actually be received, the difference is about 0.7%. If the transaction does not use the privacy RPC, it may lead to more than $200 worth of profits being earned by the "clip robot". CZ responded: "Not using privacy RPC, just testing on Pancake, will encourage builders to eliminate this MEV issue, but know that saying so may cause some snipers to complain, but for most users, it will be better to solve this problem."
