Recently, I saw the APY of yield aggregators soaring again. Frankly, my first reaction isn't "how much am I earning," but rather "how many layers of contracts are stacked behind this APY, and who is betting against whom." On the surface, aggregators seem to be one-click convenience, but in reality, they are just moving your money back and forth across different pools, with each hop involving permissions, upgrade points, liquidation parameters, plus whether the "strategy executor" is reliable or not.

These days, everyone is linking ETF capital flows, U.S. stock risk appetite, and crypto market rises and falls together for interpretation—looks lively, but what I care more about is: when market sentiment turns, will these strategies be forced to rebalance, slippage increase, or even get stuck due to congestion on a certain chain and can't withdraw?

My current approach is quite "patchwork": I don't chase the highest APY. First, I check whether the contracts are upgradeable, whether the fund flows are understandable, and whether the exit paths are smooth. If I can fix small issues, I don't expect to install a perfect system all at once... Anyway, it helps me sleep better.
