Paste your Solidity code and get an AI-powered vulnerability report with test ideas and a pre-audit readiness estimate in 60 seconds
The Problem
You shipped a contract with a reentrancy bug you didn't know about
Slither flags 50 warnings but none explain the real risk
You can't afford a $30K audit for a side project
How It Works
Drop your Solidity contract into the editor. No file uploads, no config, no account.
Scans for reentrancy, access control gaps, integer issues, and 30+ vulnerability patterns.
Findings by severity, generated test ideas, and a pre-audit readiness score.
What You Get
Every issue ranked by severity. Each finding includes the affected lines and a clear explanation of the risk.
Concrete test scenarios targeting discovered vulnerabilities. Ready for Foundry or Hardhat.
A 0-100 estimate of audit readiness. Know where you stand before spending on a professional review.
