★ Oracle source = spot DEX pool (no TWAP)
StakeWise v3's assessment for RD-F-053 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
[★ CRITICAL] Green. osETH's internal exchange rate is computed by OsTokenVaultController via beacon-chain-state-based accumulator (avgRewardPerSecond × elapsed time), not from any DEX spot price. PriceFeed 0x8023518b calls getRate() on OsTokenVaultController — confirmed no slot0(), getReserves(), or DEX TWAP call in the source. Aave's CAPO adapter prices osETH via this internal rate: search evidence confirms 'value of osETH on Aave is linked to the price of ETH, not the value of osETH on DEXs.' RedStone's DEX-aggregate feed (Balancer osETH-WETH, Uniswap v3 osETH-USDC, Curve osETH-rETH) is consumed only by external third-party protocols (Gravita, Morpho Blue, Enzyme) — StakeWise core contracts do not read this feed. No spot DEX oracle dependency in any core path.

Methodology #
Determine whether the primary oracle for any asset/market reads spot price from a single DEX pool without a TWAP window or secondary source.
