Substrate Vulnerability Scanner

1. Purpose

Systematically scan Substrate runtime modules (pallets) for platform-specific security vulnerabilities that can cause node crashes, DoS attacks, or unauthorized access. This skill encodes 7 critical vulnerability patterns unique to Substrate/FRAME-based chains.

2. When to Use This Skill

• Auditing custom Substrate pallets
• Reviewing FRAME runtime code
• Pre-launch security assessment of Substrate chains (Polkadot parachains, standalone chains)
• Validating dispatchable extrinsic functions
• Reviewing weight calculation functions
• Assessing unsigned transaction validation logic

3. Platform Detection
