rubric v1.7.0

ecrecover zero-address return unchecked

crvUSD (Curve Stablecoin)'s assessment for RD-F-019 — scored not_applicable on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

crvUSD core contracts (Controller, AMM, ControllerFactory, PegKeeper) do not use ecrecover — no signature-based operations in the CDP/LLAMMA logic. crvUSD ERC-20 token uses EIP-2612 permit which in Vyper is handled by the compiler's built-in ECDSA, not raw ecrecover with a zero-address check gap.

Methodology #

Determine whether any `ecrecover` call result is used without a `!= address(0)` guard.
