Today I thought about the IBC/message passing system. To put it simply, each cross-chain transfer actually involves trusting a set of things: the source chain won't rollback, the light client/proof verification won't fail, the relay/relayer won't go offline (although theoretically anyone can run one, in reality there are always "main players"), and the target chain's processing logic won't be broken; if there's also a bridge contract/multisig/oracle involved, then the trust layer is further amplified. Recently, people have been comparing RWA and even U.S. Treasury yields to on-chain yield products. I also ask first: are these yields based on real cash flow, or just sustained by "the bridge not failing"... Anyway, before cross-chain transfers, I always check how many components are involved. I'd rather be slow than create opportunities for setbacks.
