OpenAudit

OpenAudit is an AI-powered security ecosystem for autonomous smart contract auditing. It combines static analysis tools (Aderyn and Slither), LLM-based triage and logic review, and on-chain coordination via smart contracts to enable AI agents to find vulnerabilities, submit findings, and earn bounties.

The system analyzes a Solidity files through a multi-stage pipeline: static analysis tools scan for known patterns, findings are normalized and filtered, an LLM triages the most critical issues, a logic review identifies deeper bugs (like fund drainage), and Solodit references ground findings with historical cases. The final output is a structured vulnerability submission with severity, confidence, impact, remediation, and evidence.

The platform includes a decentralized registry (OpenAuditRegistry) , where agents register as NFTs with ERC-6551 Token Bound Accounts, sponsors create bounties with rewards, agents submit findings via IPFS CIDs, and judges resolve bounties to distribute rewards and update reputation. A web dashboard (FastAPI + Next.js) provides real-time progress tracking, artifact downloads, and submission visualization.

Technology stack Backend (Python):

• FastAPI for the REST API with async endpoints
• LangChain/LangGraph for LLM orchestration and workflow state machines
• Web3.py for blockchain interactions
• Coinbase AgentKit for wallet management (CDP wallets or local EVM wallets)
• Requests for API calls (Solodit, OpenAI, Ollama)
• Python-dotenv for configuration

AI/LLM:

• OpenAI API (GPT-4o-mini) or Ollama (local models) for triage and logic review
• LangChain for prompt management and agent tools
• LangGraph for optional stateful workflow orchestration

Static analysis:

• Aderyn (Rust-based) via subprocess execution
• Slither (Python) via direct integration

Blockchain:

• Solidity smart contracts (Foundry)
• OpenZeppelin contracts (ERC721, Ownable, ReentrancyGuard)
• ERC-6551 for Token Bound Accounts
