Should retail investors understand blockchain builders and bundles? I think it's enough to understand "not to be eaten in the market" level. Frankly, the transaction sequence you see isn't written by God; someone is packaging, someone is sandwiching. Your swap might just be a side dish in someone else's bundle. Don't get caught up in a bunch of terminology; remember two things: first, don't open slippage recklessly, and second, don't force through when liquidity is thin—on-chain, you'll just be "arranged."

What I care about more now is: whether the project team's wallet permissions have backdoors, where the money is going, whether the contracts can be arbitrarily modified... these are more practical than researching builder names. By the way, the NFT royalty disputes also seem similar: everyone wants a bigger slice, but in the end, liquidity usually calls the shots. Retail investors shouldn't see themselves as saviors; first, protect your own wallet.
