Mixed-decimals math without explicit scaling

Superstate's assessment for RD-F-017 — scored gray on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

USTB/USCC are single-token protocols (6 decimals each, USDC-equivalent). No cross-decimal mixed-asset arithmetic is apparent from the ERC-20 token design. NAV pricing handled through oracle feeds. Tool and source review needed for confirmation.

Methodology #

Determine whether shared numerator/denominator arithmetic operates over tokens with different decimals without WAD/RAY normalization or explicit decimal-adjustment.
