🔧 Technology Stack

Frontend

  • React 18 - UI framework
  • TypeScript - Type safety
  • Vite - Build tool & dev server
  • Tailwind CSS - Utility-first styling
  • Lucide React - Icon library

Blockchain

  • Ethers.js v6 - Ethereum interaction
  • ERC20 Transfer Events - Token tracking
  • Binary Search - Block timestamp lookup

Deployment

  • GitHub Actions - CI/CD pipeline
  • GitHub Pages - Static hosting
  • No backend required - Pure client-side

🎯 Key Algorithms

1. Transaction Analysis

// Identifies buy/sell from pool transfers
- Pool → Wallet = Buy
- Wallet → Pool = Sell

2. Origin Tracing

// Recursive backward tracing
1. Start with seller wallet
2. Find first incoming transfer
3. Check if source is origin point
4. If not, recursively trace source
5. Continue until origin found

3. Origin Detection

// Determines if address is origin
- DEX Pool address
- Token contract address
- Known aggregator (1inch, 0x, etc.)
- Labeled CEX wallet
- Unknown (can't trace further)

4. Block Range Handling

// Respects RPC provider limits
- Split queries into 2000-block chunks
- Sequential processing
- Progress tracking

📊 Data Flow

User Input (Pool, Token, Timeframe)
    ↓
Convert timestamps to blocks
    ↓
Fetch token transfers from pool
    ↓
Identify buy/sell transactions
    ↓
For each sell:
    ↓
Trace wallet history backwards
    ↓
Find first incoming transfer
    ↓
Recursively trace source
    ↓
Detect origin point
    ↓
Build trace chain
    ↓
Display results
