Recently, after looking into liquidation-related matters, I found that many people are focused on interest rates and comparing "on-chain like U.S. Treasury" yield products to RWA, while actually ignoring the most basic point: if the oracle feed is half a beat slow, your position's life is no longer in your hands. To put it simply, the price has already slipped down, but the contract still shows "safe," and you're still adding margin and adjusting parameters. When the update finally arrives, it hits the threshold all at once, and the liquidation bot is much faster than you.

A couple of days ago, I checked a lending pool on-chain; the oracle update only happens once at 10:23:40. My collateral position at 0x7c…91 still shows a health factor of 1.08 on the interface, but the actual transaction price has long dropped below 1… That kind of interaction—"looks fine but has already been sentenced to death"—is really counterintuitive.

Now I’d rather earn a little less than choose protocols that clearly specify update frequency and deviation thresholds, so at least I know who to blame when something goes wrong. It would be great if wallets/frontend could make the "feed timestamp" and "market price deviation" more prominent, otherwise it’s too easy to click or trust by mistake.
