On-chain this kind of "cutting in line" is basically about sorting rights causing trouble: you think that clicking swap means queuing by time, but in reality, someone can insert orders before or after you, eating your slippage and conveniently pushing the price away. The biggest impact isn't actually from big whales (they can run private channels themselves), but from ordinary users and small protocols: your small transaction gets sandwiched, with fees and slippage doubling directly; the protocol side also has to take the blame, and users will just complain, "Why is it so expensive and slow?"

Recently, with staking and shared security where yield stacking is criticized as "layering," I can understand... The more layers there are, the more they rely on "others will follow the rules," but when it comes to sorting, it’s not really about virtue. Anyway, I’ve gotten used to this: if I can use limit orders, I do; don’t force through when liquidity is thin; routing shouldn’t just look at the best price but also whether you’ll get sandwiched. Fairness isn’t innate; it’s about long-term habits: leave less room for those cutting in line, and you’ll pay less tuition yourself. That’s all for now.
