Lately I've been looking at a few yield aggregators again, and that APY on the page looks pretty tempting, but honestly it's just a chain of contracts layered on top of each other: lending pools, market making, re-staking... each additional layer adds another "counterparty," and it’s not necessarily the layer you clicked first that will blow up first if something goes wrong. A couple of days ago, I even saw hardware wallets out of stock, phishing links everywhere, and everyone's security awareness suddenly going through the roof—it's pretty real.

So should I still use them?
Use, but only the amount I can sleep peacefully with, the rest I just pretend I didn't see.

Anyway, the first thing I do when I click into any aggregator isn't checking the yield, but first finding out where they’re actually putting the money, how permissions are set up, and whether I can withdraw at any time; if I don’t understand it, I just give up—no need to gamble with my own luck.
