I keep seeing people talk about block builders and bundles lately, and it makes it seem like if you don’t understand, you’ll get “eaten.” I think retail investors only need to know up to a certain point: you don’t have to know how to write any complex stuff, but you should know that the transactions you send aren’t directly delivered to miners/validators—along the way, they can be bundled, reordered, or even taken “along the side” for someone’s arbitrage. In plain terms, don’t blindly trust that “once I click, it will definitely get filled in the order I want.”

I thought these were issues only frequent traders would run into, but one time when I swapped a small amount for a different coin, I could clearly feel the slippage being amplified… That moment made me realize that bundles aren’t mysterious—they’re more like part of the market noise.

As for that recent upgrade to a major public blockchain and whether projects will migrate—actually, I care more about this: during the upgrade, when the block production and bundling rules change, the chain’s on-chain “sense of order” will briefly be unsettled, and emotions are easier to get amplified. My approach is pretty down-to-earth: chase less, set more conservative slippage, and if it’s necessary, use limit pricing. That’s it.
