These past two days, I’ve been looking into that MEV “queue-jumping” setup again. Put simply: whoever can decide the order of transactions gets to capture the price difference. The biggest impact isn’t really those big players with scripts of their own—it’s ordinary people. You tap swap thinking you’ll be filled at the price you see, but then you get squeezed in-between, end up paying more slippage, and you may not even notice. The loss happens quietly. Sorting transactions sounds technical, but it’s really a fairness issue of “what place you get in the line.”

What’s even more annoying is that now the “Russian doll” controversies—re-staking, shared security, and layered yield stacking—are only getting louder. As the returns become more complicated, on-chain strategies are easier to target. In the end, it’s really hard to say who ends up being the victim. A colleague asked me a few days ago, “Why do I feel like I get taken every time I exchange coins?” I could only tell him not to approve things recklessly, not to chase hot pools, and to use more reliable routing and protection features… Better to be slower than to feed the queue-jumpers.
