The thing about modular chains is, frankly, the biggest change for end users might not be "more advanced," but rather that each confirmation involves more layers: execution on this chain, data on that chain, settlement back on another. If the experience isn't well-designed, it turns into waiting multiple rounds for the same transaction, with failure reasons becoming even more mysterious... Recently, when cross-chain bridges have issues, ordinary people will just remember "I have to wait for confirmation again," and then start doubting whether their routing is off or if they've been swept away by MEV.

What I care more about is: whether the router will default to sending you to the cheapest but most fragile chain; whether the wallet can explain in plain language "how long this transaction might take, where it could roll back, and who might eat the slippage." Modularization can improve chain scalability, but if the security boundaries are broken into too many pieces, ultimately users bear the psychological cost plus transaction fees. Anyway, I’d rather be slower now than gamble on "waiting for confirmation" during those abnormal quote moments. Let’s talk again next time.
