Lately I've been getting a bit obsessed with MEV, to put it simply, it's about someone being able to "cut in line" before or after you, turning the advantage of transaction ordering into profit. The biggest impact usually isn't from large traders who can tolerate slippage, but from ordinary people: you think you're trading at the price you see, but you're sneakily squeezed, with the spread and fees quietly eaten away; it's even more obvious with small amounts, and the experience is just "why is it always a little worse than expected." I don't think it can be completely eliminated, but we can tighten the screws between fairness and efficiency, at least prevent information asymmetry from becoming a default tax. By the way, recently hardware wallets have been out of stock, phishing links are rampant again, so everyone really should take an extra second before authorizing or installing plugins… Hidden losses from order manipulation are invisible, but if your wallet gets stolen, it's a direct zeroing out.
