Lately, I keep seeing people talk about block builders, bundles, MEV, and stuff like that. The truth is: retail investors don’t need to force themselves to become researchers. Just remember this: the transaction you send out won’t necessarily end up in the block in the order you expect. Along the way, someone can “bundle” a bunch of transactions together and insert them as a group—while using you as a background to skim a bit of leftover value from the edges… and that’s enough.

Then, for hands-on practice, don’t make it too complicated: use fewer private RPCs of unclear origin, don’t casually click “Unlimited Authorization,” especially if it makes you sign a bunch of things you don’t understand. Stop first and check whether the authorization object is the contract you’re actually going to interact with. If you truly need to swap a large amount of coins, split the orders, use routes you’re familiar with, and if a protected mode is available, use it. Don’t be greedy for the small gas savings.

Recently, that mainstream chain isn’t it going to be upgraded/maintained? And in the group chats, people are already speculating about whether there will be a migration. Honestly, what I’m more concerned about is that when everyone panics, they sign authorizations and cut over networks in a mess. Permission boundaries are easiest to lose precisely when everyone lets their guard down at the same time.

Anyway, I’ll just remember one thing: you can’t control the order, but you can control the authorizations. That’s it.
