Lately I've been looking at yield aggregators again, and that APY on the page really sounds tempting, but my first reaction isn't "how much can I earn," but rather "which contract is this yield actually coming from, and who's taking the blame if something goes wrong." Some claim to have auto-compounding, but in reality, it's just a series of authorizations and multiple layers of proxies. If one layer has an issue, you won't even know who to turn to... Basically, the counterparty isn't just one pool, but a bunch of contracts you've never read.

Coincidentally, that mainstream public chain is about to upgrade/maintain, and the community is starting to speculate whether the ecosystem will migrate. I'm too lazy to pick a side, so I just remember one thing: whether it migrates or not, it doesn't matter. The first question is: can I use it? And when migrating, is my money also passing through the "routing" again?

My current approach is a bit like "backing up" myself: I don't put all my strategies into a single aggregator, leaving some redundancy and fallback options. I might earn a bit less, but at least I can sleep peacefully. After all, APY won't clean up your mess.
