Mixed-decimals math without explicit scaling
BENQI's assessment for RD-F-017 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
Compound V2 fork uses Exponential.sol and ExponentialNoError.sol for all cross-token arithmetic, providing WAD-based (1e18) normalization. This is the established Compound V2 approach to cross-decimal math. No mixed-decimals arithmetic issue identified in audit reports or source review.
