Traditional audit processes take weeks or months, creating bottlenecks in DeFi development and leaving projects vulnerable to exploits. + +**Why it matters**: Over $3 billion has been lost to smart contract vulnerabilities in 2023 alone. Most projects can't afford professional audits, leading to unsafe deployments and user fund losses. --- ## ๐Ÿ’ก Our Solution -*Project Name:* [Your Project Name] -A short pitch of your solution โ€” what you built, who itโ€™s for, and why itโ€™s impactful. +**Project Name**: Smart Contract Audit MCP Server + +**The Solution**: An AI-powered Model Context Protocol (MCP) server that transforms any coding agent (Cursor, Claude, etc.) into a professional smart contract auditor. Instead of building another audit tool, we provide the missing infrastructure that makes existing AI agents audit-capable. + +**Key Innovation**: +- Converts complex security audits into conversational workflows +- Integrates battle-tested tools (Slither, Foundry) with AI intelligence +- Provides systematic audit methodologies as reusable prompts +- Enables proof-of-concept exploit generation for vulnerability validation + +**Target Users**: DeFi developers, security researchers, audit firms, and hackathon participants who need rapid, professional-grade security analysis. --- ##
