System Documentation

What problem does it solve?

This Skill identifies vulnerabilities where cryptographic signatures can be reused or exploited, protecting smart contracts from replay attacks that could lead to unauthorized transactions or loss of funds.

Core Features & Use Cases

  • Vulnerability Detection: Analyzes smart contracts for five types of signature replay vulnerabilities (same-chain, cross-chain, cross-contract, nonce-skip, expired).
  • Deep Analysis: Covers EIP-712 domain separator verification, nonce management, ecrecover edge cases, permit/permit2 safety, and ERC-1271 support.
  • Use Case: When auditing a DeFi protocol that uses EIP-712 signatures for critical operations like token transfers or governance votes, this Skill will pinpoint any weaknesses that could allow a signature to be replayed, ensuring the protocol's integrity.

Quick Start
