Who can you really trust when it comes to cross-chain transfers—one time and for all?

The more I look into it, the more I feel that IBC/message passing, if we put it plainly, is basically “trust a whole chain of things”: don’t let the source chain roll back, don’t write the light-client/verification logic incorrectly, and don’t mess up the relayer (theoretically it’s just a courier, but it can still block your messages); and when you get to the target chain and execute that step, don’t get tricked by a malicious contract. Bridges are even more intense—add multi-signatures/oracles/custodians, and that little “decentralization fantasy” in your mind instantly gets devalued… Anyway, before I make a cross-chain transfer now, I’ll first check: who the validation relies on, how timeouts/rollbacks are handled, and who can hit the pause button if something goes wrong. Recently, everyone’s been talking about staking unlocks and token unlock calendars’ selling pressure, but what I’m actually more worried about is this: when the time comes, a whole bunch of people crowd together and flee across chains, priority fees spike, and if you’re even a step late, you end up queued up—long enough to make you question your life.
