I've been lurking in the group for a long time, and seeing everyone arguing again about block builders, bundles, MEV, I can't help but chime in: retail investors don't actually need to study "how builders order transactions" to the level of writing papers. Honestly, just knowing that it affects your transaction order, slippage, and front-running is enough.

My personal standard for "enough" is three points: 1) Don't randomly click on unknown signature sources, especially those that ask you to authorize a bunch of permissions; even if the builder is malicious, they can't outdo you opening the door yourself; 2) For large token swaps, don't do it all at once—split into several transactions, set the slippage properly, and if something feels off, cancel (don't gamble with yourself); 3) Try to use reliable wallets/routes, and avoid chasing links that promise "super low fees + ultra high TPS." Recently, the Layer 2 fee wars and subsidies have been exhausting to watch—cheap is cheap, but phishing is quite active too... Anyway, I’d rather press a few more buttons on my hardware wallet, slower but more reassuring.
