Last night before bed, someone asked me again, "How deep do you really need to understand about block builders and bundling?" Honestly, retail investors don't need to memorize a bunch of technical terms. Just remember one thing: you think you're placing an order on a DEX, but in reality, someone might be bundling your multiple transactions, reordering them, and inserting them into blocks, all while taking your slippage and fee margins.

So, the essential knowledge is: don't openly reveal your intentions on-chain (especially predictable two-step trades or large price chase orders), avoid using strange routing, and don't set your slippage too loosely; if you need to perform complex operations, use private/protected submission methods—at least don't treat yourself like a buffet. As for "am I being front-run/being sandwiched," don't get obsessed and stay up until 3 a.m. reviewing it. First, check how much the actual transaction price deviates from your expectation—if it's too much, change your route, split your orders, or lower your slippage—keep it simple and direct.

Recently, with new L1/L2 projects offering incentives to attract TVL, I understand that veteran users complain about "mining, arbitrage, and selling." When the chain is congested, it becomes easier to turn into a gambling queue: the more confident you are, the more you want to go all-in, and the easier it is to become fuel for bundlers. The market never rewards confidence; at best, it rewards you for making the same mistake fewer times.
