The Internet reported that previous analysis by the crypto community found that CZ's first TST purchase transaction was sent through private RPC, but the transaction information was still leaked. The CZ transaction set a minimum purchase amount 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, it may result in profits worth more than $200 being earned by the "clip robot". CZ responded by saying: "Not using privacy RPC, just testing on Pancake will encourage builders to eliminate this MEV problem, but knowing that saying this may cause complaints from some snipers, however for most users, it would be better to solve this problem."
