These days I’ve been hearing people talk about block builders, bundles, and it feels similar to the wave of modular blockchains and the data availability layer: developers are excited, users are confused. To put it simply, retail investors really don’t need to treat it as a professional course; just knowing that “your transaction might not be included in the block in the order you want” is enough, especially for front-running, sandwich attacks, and getting squeezed out—many times, it’s just bundle packaging behind the scenes that handles it.

Right now, I only remember three things: 1) Don’t chase after low liquidity; 2) Large amounts in batches; 3) Use aggregation/ routing if possible, don’t panic and click randomly. Anyway, after being inexplicably hit with slippage three times while doing grid trading and batching, I’ve added “don’t fight the block order” to my checklist… for now.
