Recently, someone asked me again: what happens if the price feed oracle is slow? Basically, you think you're still safe, but the liquidation threshold has already been broken by the "real market price," it's just that the on-chain peg hasn't caught up yet. When it updates, liquidation bots rush in, and your position collapses suddenly like a foam of coffee... And sometimes, delays can give bad actors a chance to exploit, first distorting the price elsewhere, then waiting for the feed to catch up and harvest.

I personally keep an eye on two things: one is the timestamp of the price feed update, and the other is the price difference between on-chain trades and lending pools. A few days ago, I casually checked, and the ETH/USDC price feed interval once stretched to 45 seconds, and the on-chain swap was already off by nearly 0.8%. I immediately reduced my leverage, preferring to earn less than to get wrecked.

By the way, recently, before and after the main public chain upgrade, everyone in the group was speculating whether projects would migrate. I think whether they migrate or not is another matter; during upgrade or downtime windows, the combination of price feed delays, liquidation, and cross-chain latency makes it easiest for accidents to happen where you think "I didn't do anything, but it still blew up"... Anyway, I plan to reduce my positions in advance and sleep peacefully.
