Recently, I've been looking at some yield aggregators again. The apparent APY looks pretty attractive, but my first reaction isn't "go for it," but rather to think: where does this yield actually come from? Is the contract running strategies, or am I actually dealing with a counterparty? To put it simply, aggregators are just stitching together a bunch of protocols. What you get is "composite yield," but at the same time, you're also stacking up risks: contract permissions, upgrade pathways, fund routing, liquidation mechanisms, and even the trustworthiness of the custody/signature layer in between.

These days, the "yield stacking" approach of staking and shared security is being criticized as a copycat. I can understand the controversy: the more the yield seems to be crafted through multiple layers of packaging, the more you have to ask where the underlying cash flow is. Or is it just turning risk into a more attractive annualized figure? Anyway, I’d rather earn a little less now than wake up someday to find the contract has a problem or the counterparty goes haywire, and the APY suddenly turns into "APR: All Funds Gone"... It’s a bit annoying, but I guess I’ll just leave it at that for now.
