I've recently been asked how much retail investors need to understand about block builders and bundles... My own standard is pretty simple: knowing that the order you place doesn't necessarily go directly into a block, it might be "packed" and queued ahead of you, especially with large amounts / big slippage / chasing hot trends, which makes you vulnerable to being exploited. Going deeper into things like auctions, who collaborates with whom, honestly I can't remember after looking at it, and it doesn't change the fact that I just click confirm once.

Once, late at night, I was eating skewers and saw a certain pool on the chain suddenly get very hot, feeling the urge to jump in, but then I saw the transaction path looping around, and the slippage was way off as soon as I opened it. I just... couldn't understand it, so I didn't do anything, closed it and went to sleep. The next day, I looked back and sure enough, there were a bunch of strange sandwich orders.

Recently, RWA and US Treasury yields have been compared to on-chain yield products, I just watch for fun: even if the returns sound "stable," if the execution layer is treated as transparent, the pitfalls are still there. My approach is twofold: try small amounts, don't let slippage run wild, and for perpetuals, don't chase those one-second, one-needle volatility. Just start with that.
