Built an AI-powered smart contract security analysis platform that detects critical vulnerabilities in Solidity, Rust, Move, and Vyper smart contracts in under 60 seconds. The system uses a multi-stage AI pipeline to identify reentrancy attacks, access control issues, integer overflow vulnerabilities, front-running risks, and gas inefficiencies — returning a severity-ranked security report with actionable fix recommendations. The platform features a three-tier help system: self-service educational fix guides with real code snippets, AI-generated fix suggestions for Pro users, and an emergency agency fix pathway connecting critical vulnerability discoveries directly to senior blockchain engineers. Built on Next.js 15, Neon PostgreSQL, Drizzle ORM, Clerk authentication, and Upstash Redis for rate limiting. Includes a full user dashboard with smart contract auto-naming, version tracking, audit history, and side-by-side comparison of multiple audit runs — enabling developers to track security improvements over time.
