Evidence summary #
AggregatorStablePrice wrong price: MonetaryPolicy miscalibrated borrow rate — no immediate liquidation trigger but rate distortion demonstrated in June 2024 depeg. Collateral oracle wrong price: LLAMMA sets wrong soft-liquidation bands → potential bad debt. Chainlink offline: falls to Curve EMA only (acceptable degraded mode). Curve pool failure: PegKeeper inoperable + oracle degrades. wstETH/sfrxETH depeg: collateral mispriced via stale redemption rate.
