What problem does it solve?
This Skill addresses critical vulnerabilities arising from integer arithmetic in smart contracts, specifically when calculations involving division can lead to significant precision loss or incorrect results.
Core Features & Use Cases
- Identifies Precision Loss: Detects common patterns where division before multiplication or insufficient scaling causes truncation errors.
- Provides Remediation: Offers concrete code examples and strategies to fix these vulnerabilities, such as using
mulDivor fixed-point arithmetic. - Use Case: Auditing a DeFi protocol's reward distribution mechanism to ensure users receive the correct amount of tokens, preventing under-distribution due to faulty calculations.
Quick Start
Analyze the provided Solidity code for any instances of integer arithmetic that might lead to a lack of precision.
