Recently, I saw someone compare on-chain yield products with RWA (Real World Assets) and U.S. Treasury yields.

It sounds quite reasonable, but what I care more about is: how exactly is your yield "bridged" over?
Cross-chain bridges, to put it simply, are often just multi-signature + oracle decisions made behind the scenes, with a bunch of "waiting for confirmation" in between.
I used to think confirmation was slow, but now I think a bit of slowness is okay, at least to spread out the probability of reorganization/rollback, so you're not just watching APY and gambling on luck.

I no longer chase after asking "is this bridge really safe" explanations.
After all, nothing is absolutely safe; it's more about where they place the risk: who holds the multi-signature, what is the threshold, how do they handle oracle errors, what default confirmation count can be changed.
If they can clearly explain these and make default protections in the product, I’m willing to take a second look;
If they just talk about grand narratives... never mind.
