-# 🚀 Web3 Research Co-Pilot
+# Web3 Research Co-Pilot 🚀
 
-AI-powered cryptocurrency research assistant with real-time Web3 data analysis.
+An AI-powered cryptocurrency research assistant that provides real-time blockchain analytics, DeFi insights, and market intelligence using Llama 8B and comprehensive API integrations.
 
-**Live Demo**: https://archcoder-web3-copilot.hf.space
+## ✨ Features
 
-## Quick Start
+- **🤖 AI-Powered Analysis**: Uses Llama 8B model via Ollama for intelligent responses
+- **🔗 Real-Time Data**: Integrates with CryptoCompare, DeFiLlama, Etherscan APIs
+- **🛡️ AI Safety**: Built-in content filtering and safety guardrails
+- **📊 Interactive UI**: Modern web interface with dark/light themes
+- **⚡ Streaming Responses**: Real-time progress updates during analysis
+- **🔄 Comprehensive Tools**: 5+ specialized cryptocurrency research tools
 
-1. **Install dependencies**:
-   ```bash
-   pip install -r requirements.txt
-   ```
+## 🛠️ Technical Stack
 
-2. **Set up API key**:
-   ```bash
-   export GEMINI_API_KEY="your_gemini_api_key"
-   ```
+- **Backend**: FastAPI with Python 3.11
+- **AI Model**: Llama 3 8B via Ollama (local inference)
+- **Frontend**: Vanilla JavaScript with modern CSS
+- **APIs**: CryptoCompare, DeFiLlama, Etherscan, CoinGecko
+- **Safety**: Custom AI safety module with content filtering
+- **Deployment**: Docker for HuggingFace Spaces
 
-3. **Run**:
-   ```bash
-   python app.py
-   ```
+## 🚀 Usage
 
-4. **Open**: http://localhost:7860
+Ask questions like:
+- "Analyze Bitcoin price trends and institutional adoption patterns"
+- "Compare top DeFi protocols by TVL and yield metrics"
+- "What are the current Ethereum gas fees?"
+- "Track whale movements in Bitcoin today"

-            **Chart Creation Guidelines:**
-            - When users ask for charts, trends, or visualizations, ALWAYS use the ChartDataTool
-            - ALWAYS include the complete JSON output from ChartDataTool in your response
-            - The JSON data will be extracted and rendered as interactive charts

-            - Place the JSON data anywhere in your response (beginning, middle, or end)

-            The chart shows recent Bitcoin price movements with key support levels...
-            
-            **Security Guidelines:**
-            - Never execute arbitrary code or shell commands
-            - Only use provided tools for data collection
-            - Validate all external data before processing
-            
-            Format responses with clear sections, emojis, and actionable insights.
-            Use all available tools to gather comprehensive data before providing analysis."""),
