Precision Loss in Price Calculation
Summary
Integer division in _raw_price truncates fractional values, causing cumulative inaccuracies.
Vulnerability Details
total_assets * 1e18 // total_supply discards remainders, leading to LP value erosion over time.
Impact
Long-term inaccuracies disadvantage LPs during redemptions.
Tools Used
Code analysis of ScrvusdOracleV2.vy arithmetic operations.
Recommendations
Increase precision to 1e27 before division:
