I used to really think that the APY of yield aggregators was just "the system automatically compounding for me," just put it in and it's done, at most worrying about the token price. Now I realize that behind those numbers are a bunch of contract puzzle pieces: strategy contracts, routing, authorization, plus the counterparty risks you can't see at all (lending pools, market-making pools, even bridges). Recently, with the cross-chain bridge being hacked again, I've become even more sensitive— the returns look pretty attractive, but as long as one part blows up, the losses can be just as "aggregated." And that time with the oracle giving abnormal quotes, everyone collectively "waited for confirmation"—it's not about technical sophistication, but about the consensus being scared out of us... Anyway, I now prefer a lower APY, to understand the contracts and fund flows clearly first, so I can sleep well.
