Recently, I've been looking into the pitfalls of cross-chain bridges again. To put it simply, many bridges are not "magical technology"; they are just a bunch of signatures plus a data feeder (oracle/relay) providing guarantees for you. Multi-signature looks stable, but the real question is whether the signers are the same group and whether they can be phished or are insiders; oracles are more like "who speaks first wins." Once there's an error, waiting longer won't help.

So now I become more sensitive when I see the words "wait for confirmation": it's not about politeness, but about leaving buffer time for on-chain reorganization, rollback, or shutdown recovery, especially with recent mainstream chain upgrades. Everyone is guessing whether projects need to migrate. I actually prefer to slow down the bridge process... Better to arrive late than to get stuck in the bridge as a lesson. Anyway, I don't pretend; I try to cross as little as possible.
