AI-powered smart contract security auditor that detects vulnerabilities, generates exploit PoCs, and automates safe deployment via Sentinel.
Securing smart contracts is arguably the most critical and expensive part of Web3 development. SmartAudit AI is a comprehensive security pipeline designed to eliminate the friction and cost of professional audits.
By integrating seamlessly with the OKX Onchain OS (A2MCP compatible), developers can interact with SmartAudit AI directly. The platform utilizes a dual-agent LLM architecture (powered by LLaMA-3.1 8B for lightning-fast auditing and auto-fixing, and LLaMA-3.3 70B for complex Exploit PoC generation).
When a developer submits Solidity code or an on-chain contract address:
Auditing: The AI detects Reentrancy, Access Control, and Logic flaws, outputting a beautiful vulnerability report with a security score.
Auto-Fixing & Compilation: The agent writes a secure patch for the vulnerable code and automatically compiles it in an in-memory Solc-js sandbox to guarantee the fix is syntactically correct.
Exploit PoC Generation: It acts as an ethical hacker, drafting an internal markdown security report and generating Hardhat/Ethers.js unit tests (Regression Tests) to prove the vulnerability exists.
Secure Deployment: Finally, it hands the secured code off to Sentinel for safe, reliable deployment onto the blockchain.
In Web3, a single line of bad code can cost millions. However, traditional smart contract audits are notoriously slow, expensive, and inaccessible for indie developers or fast-moving hackathon teams.
Problems:
High Barrier to Security: Small teams deploy vulnerable code because they can't afford a $10,000+ manual audit.
False Positives: Automated tools (like Slither) throw endless false positives but don't actually tell you how to fix the code.
Lack of Proof: Most AI tools just say "there is a bug" without proving it. Developers need Regression Tests to confirm the bug is real.
Our Solution: SmartAudit AI solves this by completely automating the entire security lifecycle. We don't just point out errors—we prove them by writing the exploit, we fix them by writing the patch, and we verify the patch by compiling it in a sandbox.
<p>During this hackathon, we built SmartAudit AI from the ground up:</p><ul><li><p><strong>Frontend App:</strong> Built a stunning, responsive React dashboard with glassmorphism and cyberpunk UI elements.</p></li><li><p><strong>Backend API Gateway:</strong> Engineered a serverless Node.js backend hosted on Vercel. Overcame complex serverless limitations by migrating from filesystem-dependent Hardhat compilation to an entirely in-memory <code data-inline="true" spellcheck="false">solc-js</code> sandbox compiler.</p></li><li><p><strong>AI Agent Integration:</strong> Successfully integrated Groq's blazing-fast LLaMA models, utilizing both 8B and 70B models for specialized tasks to balance speed and intelligence.</p></li><li><p><strong>OKX ASP Registration:</strong> Successfully registered and activated our Agent Service Provider on the OKX Agent Marketplace (Identity <code data-inline="true" spellcheck="false">#9123</code>).</p></li><li><p><strong>Etherscan Integration:</strong> Implemented live on-chain code fetching so users can audit contracts directly by pasting an address.</p></li></ul>
<p><span style="color: oklch(0.147 0.004 49.25)">SmartAudit AI is currently 100% bootstrapped and was developed entirely during the OKX AI Genesis Hackathon. At this stage, we have not taken any outside funding. Moving forward, we are actively looking for ecosystem grants, accelerator programs, or pre-seed funding to expand our computational infrastructure, fine-tune our own proprietary security-focused LLM models, and scale our integration with the OKX Onchain OS.</span></p>
