These past couple of days, I've been hearing debates over TPS, transaction fees, and subsidies on the L2 side, it's been quite lively, but what I’m more worried about is something more fundamental: if the oracle feed is even half a beat slow, no matter how much gas you save in your position, you'll still get liquidated. To put it simply, on-chain liquidation doesn't look at your mental price, it looks at the fixed price in the contract; when the feed delay happens, the market has already recovered, but the contract still thinks you've exploded, so it liquidates you first... no one is hurt, but your position is gone.

My mom asked me a couple of days ago: Isn't everything real-time? How can it still be slow? I just replied with half a sentence: real-time is ideal, on-chain is a process, missing a step can cause issues. Anyway, now I get a bit nervous when I see high leverage, I’d rather earn less than risk betting on the “feed coming just in time.” This thing really isn’t something you can solve just by choosing a different chain.
