I’ve been lurking for a long time, and seeing people talk about block builders and bundles again, I can’t help but say this: retail investors really don’t need to force themselves into becoming “knowledgeable engineers.” I think it’s enough to understand two things—first, knowing that the trades you send don’t necessarily go straight into a block; along the way they may be bundled, cut in line, or even get “sandwiched,” so don’t YOLO into low-liquidity pools while running extremely high slippage; second, knowing that some routing/wallets send bundles through private channels can reduce some of the messy stuff like sniping/front-running, but it’s not a magic charm—don’t assume that picking something “anti-sandwich” means you can blindly chase it.

As for builder ecosystems, who partners with whom, or exactly how blocks are auctioned… honestly, it has little to do with me, the kind of person who executes strictly according to an exit sheet/order instruction. What I care more about is: execute in batches, use limit prices, set slippage to fixed values, and if you end up losing, withdraw according to the plan—don’t let getting “sandwiched” just once shake you so badly that you start adding positions in a panic.

The recent wave of comparing RWA and on-chain returns using U.S. Treasury yield has also been quite hot. My takeaway is: don’t just stare at whichever side “looks” like it has the higher returns—those “returns” on-chain often mean you’re the one taking on other people’s tail risk. Either way, I’ll first write the risks I can understand into my plan; if I can’t understand them, I’ll just treat them as having no returns.
