This morning, I spent half the day looking for a charger, and suddenly I realized that the current narrative of "parallel" and "sharding" is quite similar: when the wires get too many, it becomes lively, but when you really need to use it, you first ask yourself where the electricity comes from and how to replace it if it breaks. Modularization and the development of the DA layer have recently become a hot topic among developers, with a bunch of people in the group excited like it's a new toy. I'm actually more concerned with two things: where to store assets and how to withdraw if something really goes wrong. To put it simply, no matter how beautiful the story is, the critical points are in the small details like contract permissions, bridges, signatures, and authorizations; if you haven't thought through the exit routes, don’t let the excitement turn your positions into a tangled mess. Those who have experienced zeroing out first prioritize survival before chasing the trend.
