AI Smart Contract Pre Auditor

Blockhertz AI Smart Contract Auditor is a free browser-based security tool that analyzes smart contracts for critical vulnerabilities in under 60 seconds — no signup required. Paste any Solidity, Rust, Move or Vyper smart contract and get back a complete security report including an overall risk score, severity-ranked vulnerability findings, and specific fix recommendations for each issue found. The auditor detects the most costly smart contract vulnerability classes: Access control failures — responsible for $953 million in losses in 2025. Reentrancy attacks — responsible for the $60 million DAO hack in 2016 and $35.7 million in losses in 2025. Oracle price manipulation — exploited in the $114 million Mango Markets hack. Integer overflow and underflow. Unprotected initializers. Flash loan attack vectors. Unchecked external calls. Timestamp dependence. Delegatecall injection. Front-running vulnerabilities. Blockhertz AI Auditor is designed as a free first-pass pre-audit tool for blockchain developers. It is not a replacement for a professional manual security audit but significantly reduces the cost and time of professional review by catching obvious vulnerabilities before the manual audit begins. Audited contracts have 98% fewer hacks than unaudited contracts. Supports 16+ blockchains including Ethereum, Polygon, Solana, Avalanche, TON, Blast, Arbitrum, Base, and more. Free plan available. Pro plan from $19 per month for unlimited audits. blockhertz.com/tools/ai-auditor
