## ✨ Features

### Core Auditing

The AI auditor employs a **multi-agent architecture** with five specialized agents working in concert to provide comprehensive security analysis. The **Chief Auditor Agent** orchestrates the overall audit workflow and synthesizes findings from all agents. The **Static Analysis Agent** performs code analysis using industry-standard tools like Slither and custom pattern matching. The **Dynamic Analysis Agent** conducts runtime testing with Foundry and Halmos for formal verification. The **PoC Specialist Agent** generates executable proof-of-concept exploits to validate vulnerabilities. Finally, the **Validation & Reporting Agent** cross-references findings against the vulnerability database and generates detailed reports.

### Vulnerability Database

The system maintains an extensive database of **47,294 vulnerability findings** and **305,943 proof-of-concept exploits** sourced from leading security platforms. Data is integrated from **Sherlock** (16,469 findings, 304,406 PoCs), **Solodit** (7,013 findings), **DeFiHackLabs** (663 real-world exploits), **4naly3er** (22,656 findings), and **Web3Bugs** (493 academic vulnerabilities). This comprehensive database enables semantic search and pattern matching to identify known vulnerability classes.

### Advanced Features

**PoC Generation**: Automatically generates proof-of-concept exploits using AI-powered code synthesis, running 15x faster than manual creation.

**Fix Suggestions**: Provides specific, actionable fix recommendations with code examples, operating 20x faster than manual analysis.

**Risk Scoring**: Vulnerabilities are scored using a CVSS-style methodology considering impact, exploitability, and context.

**Report Generation**: Comprehensive audit reports can be exported in JSON, PDF, or Markdown formats.

**Parallel Processing**: Achieves 17.7x speedup through intelligent parallelization of analysis tasks.

**Vector Database**: ChromaDB integration with 14,291 embeddings enables sub-second semantic search.

### Web Interface

The modern **React-based dashboard** provides an intuitive interface for managing audits. Features include contract upload with drag-and-drop, real-time audit progress tracking, interactive findings display organized by severity, multi-format report export, and responsive design for all devices.

### CI/CD Integration

**GitHub Actions workflows** enable automated security auditing in continuous integration pipelines. Features include pre-commit hooks for local validation, configurable severity thresholds, Slack and email notifications, and automatic PR comments with findings.

### Collaborative Auditing

Multi-auditor workflows support team-based security reviews with role-based access control, peer review systems, consensus-based validation, and comprehensive audit trails.

### Custom Training

Protocol-specific fine-tuning capabilities allow AI models to specialize in particular DeFi protocols or contract patterns through training data management, vulnerability pattern definitions, and OpenAI fine-tuning integration.
