Prevent rounding attacks in MultiversX DeFi smart contracts by applying half-up rounding for multiplication and division. This ensures safe arithmetic operations that stop systematic value loss and block potential exploitation vectors.

Use standard precision levels BPS, PPM, WAD, and RAY for financial math on MultiversX. Enforce RAY precision for intermediate calculations to prevent precision loss, and apply BPS or PPM specifically for fee calculations.

Calculate fees and percentages safely in a DeFi protocol by applying BPS or PPM precision utilities. These methods securely apply percentages and enforce half-up rounding to ensure accurate fee distribution without value leakage.

Safely rescale values between different precision levels by using a secure rescaling method. This prevents precision loss when converting values between WAD, RAY, BPS, and PPM standards during complex DeFi operations.

You need RAY precision for interest rate calculations in lending protocols to maintain maximum accuracy. Using RAY for intermediate calculations combined with half-up rounding ensures fairness and prevents rounding exploits over time.

Precision loss occurs in DeFi financial math due to anti-patterns in multiplication and division without proper scaling. Fix it by enforcing standard precision levels for intermediate steps and applying half-up rounding to secure the rescaling process.
