Recently, everyone has been talking about modularization and the DA layer, developers are excited beyond measure, while users (including myself) basically just think: what does this have to do with me... Frankly, the most direct change for end-users isn't "the chain has become smarter," but rather that when you click confirm, there are several layers behind it: executing on this layer, throwing data on that layer, settling elsewhere. The result is that your wallet might have more network options, cross-chain transfers, and occasionally waiting for proofs, with the feeling of "why do I have to sign again?"

For someone like me who watches slippage every day, I become even more nervous: the longer the path, the easier it is for someone to exploit the gap between quoted prices and actual transactions, and the trap is more likely to be hidden in that unseen layer. The only things I can do are simple: avoid large slippage, use private/protected routes when possible, don't hard push during congestion—just prioritize survival.

What I’ve learned isn’t techniques, but that: how the chain is split doesn’t matter; what matters is that every extra step you take, you must assume someone is waiting to take advantage of you at that step.
