Recently, many people have been complaining that validators/miners are earning too much, and that MEV front-running makes the ordering unfair... I’m annoyed too, but retail investors really don’t need to study “block builders, bundles” like they’re academic papers. To put it plainly, you just need to know this: the transaction you send may not be included in a block in the exact order you submitted it. In the meantime, it could get bundled into a single clump (bundle) that bids for priority to cut in line. As a result, with the same action, the execution price and slippage can swing around. My “good enough” standard is: when you see popular pools on-chain, high volatility, and thin liquidity, you’ll likely get singled out by default—place fewer large market orders; if you can, split them into batches; and don’t try to squeeze in for that one second with everyone else. The rest is up to your wallet/router to optimize—don’t stress yourself out.
