Recently, I've been browsing yield aggregators again, and the APY displayed in rows on the page looks quite attractive, but my first reaction now isn't "go for it," but rather: Is this yield actually the contract doing the work, or is the counterparty just paying out money? Especially those new L1/L2 chains that boost TVL immediately with incentives—it's not without reason that veteran users complain about "mining, selling, and dumping." When you enter a pool, the other side might already have a withdrawal route prepared.

I now basically first check the strategy contract permissions, whether it can be upgraded, emergency pause features, and so on, then see which pools the funds actually went into, and whether you've been diverted into some strange lending or market-making contracts. To put it plainly: don't just stare at the annual percentage yield; first think clearly about "who ultimately gets the money" and "who takes the blame if something goes wrong." If you can monitor with scripts, do so; if not, try small positions to test the waters. Anyway, I don't want to be the one who only realizes later that I was just feeding data to someone else.
