Recently, everyone has been talking about block builders and bundles as if it were mysticism, to put it simply, retail investors only need to know that "they might be front-run/ sandwich attacked," no need to memorize the full set of terminology. Just remember: the transaction you submit may not be included in the block in the order you want; someone might bundle a bunch together and insert them, casually treating your slippage as a buffet... funny and infuriating. My approach is very simple: don't use outrageous slippage, don't chase pools that are obviously about to be front-run, and when necessary, use private/protected routing, at least don't make it obvious. Recently, AI agents are automatically placing orders and hyping it up, but safety settings are just glossed over; anyway, if something goes wrong, they won't compensate you. First, understand the authorization and signing process clearly.
