I used to think that MEV and this kind of "queue-jumping fee" were far from me, but after swapping a token on the chain myself or adding a pool and getting front-run a few times, I finally understood: it's not about some grand narrative, it's about the mentality when your small orders suddenly experience larger slippage or the execution price inexplicably worsens. To put it simply, whoever holds the ordering rights, fairness gets squeezed out — arbitrageurs profit from certainty, while we pay with uncertainty.

Now my approach has also become more conservative: if I can set a limit order, I do; if I can split into batches, I do; I avoid rushing in during congestion; I still play around with staking and layered yields, but as soon as I see black-box routing or strange "optimal execution," I cut the weeds first. Recently, modularization and the DA layer have been the hot topics, developers are excited, but users are confused... I only care whether it results in fewer front-runs in the end, otherwise no matter how new the narrative, it feels a bit hollow. That's all for now.
