It might be true that there are alternative assets on some chains, but for Polygon v3, for example, there is, right now, no stablecoin alternative while borrowing, as all stablecoins have been paused. This also means that there is no way to collateralise with a stable asset. So you’re basically locked into volatility.
That could be a problem for some users, considering the high interest rates right now. But a small problem, in my opinion.
Another attack vector? The interest rates are still fairly small, considering that this issue will be resolved within a few days. And again, already mentioned in this thread: What is the alternative?! Would you rather have your funds at risk?
