System Documentation

What problem does it solve?

Signature vulnerabilities in Solidity enable replay, malleability, and unsafe verification patterns that can compromise user funds and contract integrity.

Core Features & Use Cases

  • Secure verification patterns: guidance on EIP-712 domain separators, nonces, and safe signature recovery.
  • Attack vectors and mitigations: coverage of replay attacks, malleability, and permit front-running.
  • Practical examples: scenarios for permit, meta-transactions, and gasless approvals.

Quick Start

Ask me to audit a contract’s signature verification flow and implement safe patterns.
