What problem does it solve?
This Skill identifies and helps mitigate a critical security vulnerability in Solidity smart contracts where the return values of low-level calls (.call(), .send(), .delegatecall()) are not properly checked, potentially leading to unexpected state changes and exploits.
Core Features & Use Cases
- Vulnerability Detection: Automatically scans Solidity code for instances of
.call(),.send(), and.delegatecall()where the success or failure status is ignored. - Severity Classification: Assigns a 'Medium' severity and 'High' confidence to detected vulnerabilities based on specific detection rules.
- SWC Mapping: Links detected issues to the relevant Smart Contract Weakness Classification (SWC) identifier (SWC-104).
- Use Case: A smart contract developer can use this Skill to proactively audit their code before deployment, ensuring that all critical external interactions are handled safely and robustly.
Quick Start
Audit the provided Solidity contract for unchecked return values in low-level calls.
