rubric v1.7.0

Mixed-decimals math without explicit scaling

Save (formerly Solend)'s assessment for RD-F-017 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

Solend operates across assets with different decimals (SOL=9, USDC=6, etc.). Kudelski audit covered decimal math in v1.0 scope. The 13+ isolated pools added post-audit introduce per-pool decimal configurations not confirmed as within Kudelski audit scope. No confirmed finding of un-normalized arithmetic, but audit coverage of post-v1.0 pools is unverified.

Methodology #

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