Lately I keep hearing people talk about block builders, bundles, MEV, and so on. As a slow-moving retail investor, I don't need to obsess over every detail to the level of a research paper. Basically, you just need to understand: the transaction you send out may not be included in the block in the order you expect; some people will "pack" a bunch of transactions together, front-run or sandwich you, especially in on-chain token swaps where slippage is too large, making it easy for others to profit at your expense.

So my current "sufficient" understanding boils down to two points: first, don't push through during extreme congestion; second, tighten slippage when swapping tokens, and try to use protected routing or private transaction entry points (the fewer people see your transaction, the better). As for who the builder is or how the bundle is assembled, I just glance at the data and don't get too caught up.

By the way, recently I’ve been comparing RWA, US bond yields, and on-chain yield products. I’m quite interested but also a bit anxious: how much of that "yield" on-chain is actually complex structures plus information asymmetry? Next time, I plan to start with small, transparent products… Do you think retail investors need to learn anything more to avoid being blind?
