As soon as my phone vibrated, a red dot popped up on my wallet notification: Transaction failed. Honestly, it was my own fault — I set the slippage just like usual, but the pool depth was as thin as paper, and a bunch of people front-ran and squeezed the spread. I still foolishly pressed "Confirm." Looking back, there are really only three things: don't blindly trust the default slippage; check the depth/order book, or you're just sending gas to others; placing an order with a slow pace can also be deadly, especially when liquidity has just been drained. Recently, before and after the main chain upgrade/maintenance, everyone was guessing whether projects would migrate. I think a more realistic view is: routing and liquidity will get chaotic for a while, don’t rush in blindly, wait until the hype passes before clicking buttons. Anyway, I’m going to hold back for a couple of days.
