Recently, I see everyone is talking about "unlocking the calendar" again. Once they unlock it, they start to feel anxious and overwhelmed... I'm actually more afraid of another kind of "unlock": when you cross-chain, you also conveniently unlock your trust to a bunch of components. Whether it's IBC or various messaging/bridging protocols, honestly, it's not just "click once to arrive," but you have to trust: that the chain sending the message won't rollback or maliciously act, the relayer/relayer won't mess around (at least not block you), the light client/validator set on the verification side won't be compromised, the bridge contract itself won't have vulnerabilities, and on top of that, whether your wallet's signature gave unlimited permissions. Last week, I reviewed a theft case— the bridge wasn't broken; it was someone signing an approval that looked like cross-chain permission... Anyway, now before I cross-chain, I always check: who am I trusting this time, and to what extent.
