Over the past two days, some people have asked me again, “Do block builders and bundler retail need to study scripting?” Frankly, no. If you truly need to understand it all, then go do market making / search for MEV… For retail, I think knowing three things is enough: first, when you make a swap, it doesn’t necessarily get included directly in a block—it may be packaged into a clump; second, the slippage/trading method you set will determine whether you’re essentially feeding someone; and third, don’t blindly trust “failure is safe”—failure may also expose the route for others to see.

My current approach is pretty crude: for large amounts, split the orders, and turn on limit price/protection mode whenever you can; don’t be greedy for the absolute best route—I'd rather pay a bit more in fees for certainty. As for whether “bundles are doing harm,” it’s just like the recent fights over privacy coins/mixers and whether it’s compliant—the debate is all about taking a stance until people get heated… I don’t bother choosing sides; I only care that my order doesn’t get distorted at the moment I place it. I’m tired, but still here—when I see strange fills, I go back to look up the transaction path, anyway.
