Just now I was being stupid again: a small trade failed twice in a row, and after reviewing it, it’s not the chain’s problem, it’s that I slipped too tightly + the pool depth wasn’t enough, and I was in a rush to chase that move. To put it simply, when the depth is thin, trying to "save on slippage" is just fighting myself, especially when the market jitters and the quotes drift away, wasting gas.

Later I changed to splitting into two trades, waiting a few seconds to see the match before placing the order, and it went smoothly. Rhythm is quite mysterious; the more anxious you are, the easier it is to make mistakes. Recently, everyone has been testing on testnets for incentives, guessing whether the mainnet will issue tokens, I understand that fear of missing out, but really don’t push hard just for points—failing a few times might be more painful than the "expected" gains.

Just a quick reminder: remember to revoke authorization after interaction. I anyway treat it like locking the door; I feel at ease only when it’s closed.
