I used to think that "cross-chain = bridging," as long as I click confirm, it's like moving tokens from A to B, at most just paying higher fees. Now I realize that each cross-chain is essentially a gamble on a series of components not to fail: the source chain itself not to rollback, how to prove messages (light clients/relays/validators) not to be bypassed, how the target chain executes without being front-run, plus an additional layer of custody/multisig/contract security on top of the bridge. Any weak link can cause an accident.

I can accept message passing like IBC a bit more, since at least the trust model is "written on paper," not entirely relying on a single operator’s endorsement. But don’t idolize it either; it still depends on the implementation and the security of the other chain.

Recently, people are comparing RWA and even US Treasury yields with on-chain yield products. All I want to ask is: what is this yield trusted on? The interest rate is secondary; I care more about exit channels and worst-case scenarios. Anyway, I won’t cross-chain all at once now—I'll do it in batches, leave room to exit, and follow a plan.
