Recently, someone sent me a yield aggregator link and asked, "With such a high APY, can I go for it?"

I usually don't look at the numbers first; I open the contract to see exactly how the money is being transferred:
Is the funds directly going into the strategy contract, or is there an insurance vault first, then borrowing/lending outside?
Is there an upgrade path, and can an administrator change the routing at any time?
Most importantly, who is the counterparty—do you think it's "protocol yield," but it might actually be betting against a pool, a market maker, or even a cross-chain bridge.

To put it simply, APY is just the result; the path is the risk list.
Especially with those "auto-compounding + reward stacking" schemes, once the rewards collapse, it looks very much like a blockchain game with inflation and studio bots, with the coin price spiraling—surface data still shows positive, but inside it's already empty.
Anyway, I now prefer to earn less but thoroughly review the call chain and permissions, so I can sleep more peacefully.
