To be honest, when I see that string of APYs on the yield aggregator, I automatically question: is the strategy really profitable, or are the contracts just adding a few extra layers, and the counterparties stacking up, making it look good in the end? When you put your money in, it's not really like "buying a yield," but more like splitting trust into many parts: the aggregator contract, the underlying pools, lenders, oracles, liquidation logic... Any hiccup in any link could be a big problem.

Recently, with the staking and shared security setup being criticized as a "nested doll," I can understand it quite well. The yield stacking sounds appealing, but the risks also stack up—it's just not written on the page. Anyway, I’d rather take a smaller gain now than turn myself into the last link in a chain of contract calls. I’m not even sure if that’s conservative or not, so I’ll just leave it at that.
