• Strategy Sommelier: Wine-themed AI investment strategies based on risk profiles
• Smart Chat Assistant: Intelligent DeFi guidance and market insights
• Automated Yield Optimization: AI-driven recommendations for maximizing returns
• Risk Assessment: Comprehensive portfolio analysis and risk management

🏗️ Technical Architecture

• Backend: Python Flask with SQLite database
• Blockchain Integration: Web3.py for Ethereum/Polygon, Solana SDK for Solana
• AI Integration: Comput3 AI API with LLaMA models
• Protocol Compliance: Model Context Protocol (MCP) JSON-RPC 2.0
• Frontend: Bootstrap 5 responsive design
• Deployment: Gunicorn on Replit infrastructure

🔧 DeFi Protocols Supported

• DEX Operations: Uniswap V2/V3, SushiSwap, QuickSwap, Raydium, Orca
• Lending: Aave V3, Compound V3, Solend
• Yield Farming: Liquidity provision and reward farming
• Staking: Liquid staking through Lido

🛠️ Installation Steps

1. Clone the repository:

   git clone [your-repo-url]
   cd onedefi
   

2. Install dependencies (handled automatically by Replit):

   uv sync
   

3. Set up environment variables (see Environment Variables section)

4. Run the application:

   python main.py
   

The application will start on http://0.0.0.0:5000 and be accessible via Replit's web interface.

🔐 Environment Variables

Create a .env file or set the following environment variables:

# Required for AI features
OPENAI_API_KEY=your_comput3_api_key_here

# Blockchain RPC URLs (optional - uses public RPCs by default)
ETHEREUM_RPC_URL=https://cloudflare-eth.com
POLYGON_RPC_URL=https://polygon-rpc.com
SOLANA_RPC_URL=https://api.mainnet-beta.solana.com

# Development settings
USE_TESTNET=true
DEBUG=true

# Flask settings
FLASK_ENV=development
SECRET_KEY=your_secret_key_here

Note: For AI features to work, you'll need a Comput3 API key. Set it in the Replit Secrets tab as OPENAI_API_KEY.

📖 Usage Example

1. Web Interface

Navigate to your Replit URL to access the web interface:

• Dashboard: Portfolio overview and analytics
• AI Features: Access Portfolio Doctor, Strategy Sommelier, and Chat Assistant
• API Docs: Complete API documentation

2. MCP Protocol Usage

import requests

# Analyze portfolio
response = requests.post("https://your-repl-url/mcp", json={
    "jsonrpc": "2.0",
    "method": "defi.portfolio",
    "params": {
        "wallet_address": "0x742d35Cc6641C88c4f95bbCdDB96a2b0f0f3f6b7f",
        "blockchain": "ethereum"
    },
    "id": 1
})

3. AI Features Usage

# Portfolio health check
response = requests.post("https://your-repl-url/api/v1/ai/portfolio-checkup", json={
    "wallet_address": "0x742d35Cc6641C88c4f95bbCdDB96a2b0f0f3f6b7f",
    "blockchain": "ethereum"
})

# Create investment strategy
response = requests.post("https://your-repl-url/api/v1/ai/create-strategy", json={
    "goals": "I want steady 8% returns with low risk",
    "wallet_address": "0x742d35Cc6641C88c4f95bbCdDB96a2b0f0f3f6b7f"
})

🐛 Known Issues

1. Icon Warnings: Feather icons 'wallet' and 'brain' are not valid - these are cosmetic warnings that don't affect functionality
2. Testnet Mode: Currently runs in testnet mode for safety - set USE_TESTNET=false for mainnet operations
3. Rate Limits: Public RPC endpoints have rate limits - consider using premium RPC providers for production
4. AI Dependencies: Some AI features require internet connectivity to Comput3 API
