Modular chain sounds very fancy, but honestly, the biggest change for someone like me, a end-user, is that: the same task suddenly has a bunch of "most efficient routes" to choose from. Before, if one route was congested (Gas explosion), you had to force through it; now, if the main network is expensive, you can bypass it with L2/sidechains, then use a bridge... The result is saving a bit of money, but your brain gets more tired, and a wrong step means more learning costs. It's both funny and frustrating.

Recently, hardware wallets have been out of stock, and phishing links are everywhere. The more "routes" there are, the easier it is to be lured by fake interfaces. Anyway, now I treat any unfamiliar link as high Gas: don’t click, consider it a weight loss method. That’s all for now.
