Lately I've been looking into the pitfalls of cross-chain bridges. To put it simply, most aren't "hacked because hackers are so clever," but rather because the design inherently assumes someone can alter the facts you see. Multi-signature sounds secure, but in reality, it's just a few people making quick decisions: keys being phished, insiders, or temporary signers, and the bridge can just "allow passage." Oracles are the same—once the price feed/status feed is manipulated, you see it locked on chain A, but it can be minted on chain B, and it's too late to argue afterward.

So now I only trust two things in cross-chain: first, that the confirmation count is truly sufficient (don't complain about the slow speed—that's to make "reversal costs" more expensive), second, whether the bridge's risk control will shut down immediately during anomalies. The hype about rate cut expectations is lively; when the dollar index swings, risk assets either rally or panic together. But a single breach of a cross-chain bridge has nothing to do with macroeconomics—it's purely because you're handing your money over to a process that "could be altered." Anyway, I'd rather miss out on some gains than pay tuition on the bridge.
