Saw several aggregator pools; the APY looks pretty impressive at first glance. But when you dig into the contract, some of the underlying is just a basic swap plus a rewards token. If that rewards token itself has shallow liquidity, or if the contract has permission to transfer funds, then no matter how high the APY is, it won’t matter. Anyway, lately when I look at this kind of project, I’ll always first skim the audit report to see whether there’s counterparty risk—for example, fund permissions, withdrawal delays, and so on. There are a lot of tutorials, but I only watch the ones that clearly explain the underlying logic; otherwise I don’t feel confident. Recently, Layer2 teams have been competing over TPS and fees, with plenty of noise. But honestly, some aggregator cross-chain arbitrage just relies on these speed differences to make money. Everyone gets excited over the numbers and doesn’t pay attention to how the underlying actually brings the money back. Forget it—let’s leave it at that. It’s still better to check the contracts more yourself.
