Mixed-decimals math without explicit scaling
Maple Finance'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 #
Maple operates with USDC (6 dec) and USDT (6 dec) as pool assets and WETH (18 dec) / WBTC (8 dec) as collateral. Multi-asset decimal handling required. 0xMacro M-2 finding (safe downcasting) was fixed. No confirmed live mixed-decimal arithmetic issue, but architecture warrants attention.
