Mixed-decimals math without explicit scaling

Evidence summary #

V3 uses sqrtPriceX96 encoding which normalizes for token decimal differences. V2 uses reserve-based math with no cross-decimal arithmetic in core pair. StableSwap (Curve fork) is designed for same-decimal stable pairs. No auditor-reported decimal math issue across 6 firms.
