Just got a notification on my phone about a successful cross-chain transfer, and I was stunned: what exactly am I trusting… To put it simply, a transfer from A to B is not just “sending a message.” First, trust the source chain itself not to rollback or get reorganized; then trust that the proof / relay operators are seriously forwarding without any ulterior motives; if you're using a bridge, you also have to trust the bridge's validators / multi-signature groups not to collectively mess up, ensure the contract doesn’t do anything weird, and that the receiving logic on the target chain isn’t replayed. The IBC approach at least clarifies “who is responsible for proof,” but in the end, you're still trusting a series of component and human operation processes. The airdrop season has made everyone act like clocking in at work, with task platforms becoming more and more meticulous about anti-witchcraft measures. Now I usually do small test transfers first for cross-chain… Impulses can be impulsive, so I add a little to my position and then stop.
