Oracle providers used

Stake DAO's assessment for RD-F-048 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

Core liquid locker path (VoterBase, DepositorBase, AccumulatorBase, CurveStrategy, Strategy) uses ZERO price oracles — source-verified across 6 contracts. Peripheral Morpho lending vault path uses Chainlink push-oracle feeds (19 feeds in data cache: ETH/USD, USDC/USD, BTC/USD, LINK/USD, etc.) via custom Curve-LP oracle adapters (OracleChainlinkAdapter, CurveStableswapOracle, CurveCryptoswapOracle). Oracle architecture cleanly separated: core locker is oracle-free; Morpho lending vaults consume Chainlink with documented staleness checks. Trust Security 2025-08 audit specifically covered Stake DAO misc Curve oracles.
