Just now my phone popped up a red dot: a certain yield aggregator's "APY explosion," my first reaction wasn't excitement, but to check the gas curve... When there's congestion, you know someone is rushing to bundle, and the yield might be eaten up by slippage + fees. To put it simply, APY is just a front-end number; the real question is who is actually helping you move your money behind the scenes: does the contract have permission access, is the funds circling through someone else's pool, and in case of bad debt/liquidation, who covers the loss—these are the true counterparties. Recently, modularization/DA narrative has been hot again, developers are thrilled, but ordinary users see cross-platform aggregators more like black boxes, and I’m half confused myself... Anyway, I only dare to try small amounts now, first review the contract address, permissions, and the layers of protocols involved before proceeding.
