Recently, everyone has been chatting about whether people should migrate before or after the upgrade/maintenance of that mainstream public chain. My first reaction isn’t “whether to migrate,” but this: will the oracle pricing that those lending and leverage products use get jammed up as well? To put it plainly, the most sinister part of delayed oracle price feeds is— you think everything is still safe, but the liquidation line has already been reached; or, the other way around, the price clearly comes back, yet liquidation is still calculated using the old price, and your positions get “finished” with a follow-up strike. When the chain stalls, nodes jitter, and the oracle update interval gets longer, liquidation bots become as fast as they’ve caught a whiff of blood, and ordinary users adding margin manually just can’t make it in time. Anyway, I’d rather use less leverage now, and I’ll check the oracle update frequency and the tolerance deviation in advance—before the upgrade window, I’ll pull back both my permissions and positions. Don’t wait around for the system to give you a lesson.
