Recent Curve pools, including USD0++/USD0 pool have very nice non-manipulatable oracles. They are 10-minute EMAs, but that is more than sufficient for this kind of price action.
Feel free to ask any details about the best practices of integrating these!
Meanwhile sUSDe market at http://lend.curve.fi. sUSDe dipped a little bit, and some users were soft-liquidated and... unliquidated. So everyone's position seems fine despite dipping below liquidation price!
Btw this market supports up to x35 leverage and gives points 👀
