On February 24th, CZ responded to the reason why the previous on-chain transaction failed, saying that he did not use private RPC and would encourage builders to eliminate this MEV issue. I know this may cause some sniper complaints, but for most users, it will be better. According to previous reports, some analysts pointed out that an address preempted CZ's on-chain transactions but was caught by a clip, which ultimately led to the failure of CZ's transactions.
