MEV, to put it simply, is on-chain front-running fees. Anyone who thinks they're just lining up to buy bubble tea ends up behind a bunch of "familiar channels." The biggest impact isn't on those old gamblers who always use a single transaction (they're already used to slippage), but on regular people doing swaps, liquidations, or running strategies: the moment you click confirm, the price has already been manipulated by someone else.

What's even more awkward is that the blame for the ordering often gets pushed back to "you set your slippage too high/too low." Fine, I guess I don't understand on-chain social etiquette.

Recently, modularization and DeFi layer narratives have heated up again, and developers are excited as if at a concert, while users only feel: why are my transactions still being front-run? After changing several layers of building blocks, the front-running hands haven't disappeared... Anyway, now I tend to move less during high volatility, preferring to miss out rather than be part of someone else's exit event.
