Just reviewed the on-chain transaction from last night, and I feel a bit scared now: I originally wanted to move some assets out of L2, and in my haste, I took a "seems faster" route, but the execution price got squeezed a bit, almost thinking I clicked wrong. Only afterward did I realize it was probably due to the ordering issue: you think it's first-come, first-served, but someone can cut in line, and what they eat isn't "air," but the slippage and time difference for small orders like ours.

Recently, there’s also a bunch of AI agents doing automatic trading over there, hyping it up as if everyone has a quant team, but honestly, it’s more like competing to see who’s better at dealing with the order matching rules... I have one standard now: can I use it? Can it help me avoid these pitfalls? Otherwise, no matter how smart it is, it’s just helping others more intelligently extract from me. For now, I’ll set stricter slippage limits—better to be slow than sorry.
