Lately, people keep asking me what modular blockchains have to do with me. Honestly, you’re not the one writing code. My feeling is: for end users, it may not be “cooler,” but it’s more likely to become “cheaper/faster/more choices,” and the same wallet might suddenly have a whole bunch of networks that you need to keep switching between… whether the experience is good or not depends on whether the wallet, bridges, and sequencers—these kinds of middleware layers—are reliable.

But modularity also has a very real point: the attack surface for trust gets bigger. In the past, you probably only needed to trust one chain. Now you may need to trust the execution layer, data availability, bridges, and a whole set of service providers. If any part goes wrong, the unlucky person is ultimately the one who clicks “confirm.” As a security-focused person, I have to admit that sometimes I also need to be reminded: don’t slip and click an unknown link just because the “transaction fees are cheap.” Recently, hardware wallets have been out of stock, phishing links have been popping up more frequently, and everyone’s security awareness has gone up—but scammers are also working harder… Anyway, I’d rather be a bit slower now, double-check the address and domain name twice, and do it this way for now.
