At first, I really thought on-chain transactions were just "first come, first served," where whoever pays more gas gets to go first, which seemed like fair competition. Now, looking at MEV/ordering systems, honestly, it's like some people can see your queue number, then cut in line at the last moment, and even casually take your slippage profit—what's affected isn't "who's better at playing," but that ordinary users are quietly paying an extra fee every time they swap. What's even more annoying is that the cross-chain bridge was recently hacked again, and everyone started shouting "wait for confirmation," but when the ordering isn't transparent, you might wait forever and still get caught in the middle as a scapegoat; the oracle glitch was even more obvious—when prices spike abnormally, the front-runners are the first to exploit the information advantage. Anyway, now when I bridge assets or swap large amounts, I prefer to go slower, split the transactions, set lower slippage... rather than become someone else's ATM.
