Recently, many people have been complaining that validators/miners are earning too much, and MEV front-running is causing unfair ordering… I also find it annoying, but retail investors really don’t need to study “block builders, bundles” into papers. To put it simply, you just need to know: the transaction you send may not be included in the block in the order you click to send it; it might be bundled into a group (bundle) for bidding and jumping the queue; as a result, the same operation’s execution price and slippage can fluctuate. My “sufficient” standard is: when you see popular pools on-chain, high volatility, and low liquidity, assume you will be targeted; avoid placing large market orders, split orders if possible, and don’t compete with others for a second. The rest can be left to wallets/router to optimize, don’t stress yourself out.
