The word "modularization" sounds pretty advanced, but basically the most direct changes for end users are just two: first, more chains, more bridges, and a bunch of networks switching in and out of wallets; second, routing/sorting people have become more "smart," so when you click a swap, it might already be split into several parts running in different places, with lower fees but also making it harder to figure out who’s really taking your cut. The experience might not necessarily be better, it’s just more like placing an order in a multi-layered delivery system—timeliness depends entirely on scheduling. Recently, some people have criticized the lag in label systems of on-chain data tools and how they can be misleading. I can only say, don’t be too superstitious about "who is labeled as who," because after modularization, paths are more fragmented, and misjudgments are more normal. Anyway, I don’t regret the outcome; I just don’t want to bother looking deeper into what’s really happening with transaction routing and inside the blocks.
