rubric v1.7.0

Immutable oracle address

crvUSD (Curve Stablecoin)'s assessment for RD-F-180 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

[★ CRITICAL — flagged for T-14 orchestrator tracking per PD-017] Two-layer picture: (1) AggregatorStablePrice pool list IS admin-mutable via add_price_pair/remove_price_pair/set_admin functions; admin = Curve Deployer 2 EOA (0xbabe61887f1de2713c6f97e567623453d3C79f67) per Etherscan constructor args — unclear if transferred to Ownership Agent. (2) Collateral price oracle contracts (CryptoWithStablePriceAndChainlinkFrxeth): all oracle addresses FULLY IMMUTABLE — no admin setter, all set at construction. set_use_chainlink toggles Chainlink activation but does NOT change the feed address. LLAMMA/Controller oracle address: set at deploy, no set_price_oracle found. YELLOW not red: AggregatorStablePrice pools must be valid Curve stableswap pool type (type-checked), and collateral oracle addresses within individual contracts are immutable. Issue: if Deployer 2 EOA still holds AggregatorStablePrice admin, this is an unchecked admin oracle-manipulation surface.

Methodology #

Determine whether any collateral oracle address is marked `immutable` in protocol config with no admin-replaceable adapter wrapper, preventing the protocol from repricing when the upstream asset depegs.
