Lately, a lot of people have been talking about block builders and bundles, as if retail investors can’t survive unless they don’t understand everything… I think knowing just enough to “not get scammed” is enough. To put it plainly: the transactions you submit may not end up in a block in the order you specified. Builders may bundle a bunch of transactions together and slip in little maneuvers like front-running or sandwiching. The slippage and execution prices you see sometimes aren’t “just bad luck”—it’s because the mechanism allows others to be half a step faster than you.

So, retail investors should remember two things: first, don’t force trades into pools with thin liquidity; second, don’t blindly trust “large on-chain transfers / hot-cold wallet movement = smart money is coming.” Many times it’s just moving coins, doing arbitrage, market making, or switching custody—hardly anything to overread. As for the deeper builder/relay details, sure, you can study them if you really want to, but don’t treat them as a mandatory daily lesson for staring at charts… As for the rest—you guys add one more line yourself?
