authorization-txorigin

What problem does it solve?

This Skill identifies and helps remediate a critical security vulnerability in smart contracts where the use of tx.origin for authorization can lead to phishing attacks and unauthorized access.

Core Features & Use Cases

• Vulnerability Detection: Pinpoints the use of tx.origin in authorization logic.
• Severity Classification: Flags tx.origin usage as a High severity risk.
• Remediation Guidance: Provides clear instructions to replace tx.origin with msg.sender.
• Use Case: Automatically scan your Solidity codebase to ensure that no critical functions are protected solely by tx.origin, preventing potential exploits where a user might be tricked into calling a malicious contract that then calls your contract.
