The phrase “modular chain” has been around for a while, but the two most intuitive changes for end users are: it’s cheaper and faster, and “crossing back and forth” happens more often. The gas you save is obvious and everyone understands it—what’s not so obvious is the trouble it brings: more bridges, multi-chain wallets, and all kinds of authorizations, meaning the security responsibility ends up on you. Back then, the pitfall was choosing the wrong chain; now, one mistake in signing—one signature/signing error—and it’s gone.

Recently, AI agents automatically helping you interact or even trade has been quite a hot topic too. What I’ve seen is that there’s more hype than security scrutiny: having it click buttons for you is fine, but it’s managing your private keys and permissions that’s the real landmine. In any case, I still stick to my old habits—record every authorization. Batch operations are possible, but the stop-loss and permission revocation have to keep up; otherwise, modularization smooths out the experience, and the risks get amplified in a “no one notices” kind of way.
