System Documentation

What problem does it solve?

This Skill identifies and helps remediate vulnerabilities in smart contracts where predictable or manipulable on-chain data is used to generate random numbers, potentially leading to economic exploits.

Core Features & Use Cases

  • Vulnerability Detection: Pinpoints the use of deterministic on-chain data like block.timestamp, blockhash, block.number, and block.prevrandao for generating random values.
  • Exploit Analysis: Provides examples of how attackers can exploit weak randomness and details detection heuristics.
  • Remediation Guidance: Offers solutions such as using Chainlink VRF or implementing commit-reveal schemes.
  • Use Case: Auditing a decentralized lottery smart contract to ensure the winner selection is truly random and not influenced by miners or other network participants.

Quick Start
