+# Zapper XYZ Integration for Swipe Mode
+
+This document describes the integration of Zapper XYZ API to provide comprehensive token market data and price charts in the swipe mode feature.
+
+## Overview
+
+The swipe mode now displays enriched token data powered by Zapper XYZ, helping users make informed decisions about whether to keep or sell their tokens. Each token card shows:
+
+- **Price Charts**: Visual representation of token price history
+- **Market Data**: Market cap, 24h volume, and holder count
+- **Price Changes**: 24-hour price change percentage
+- **Token Metrics**: Additional insights from Zapper's comprehensive data
+
+## Implementation Details
+
+### 1. API Route (`/api/token-market-data`)
+
+Created a new API endpoint that fetches token market data from Zapper:
+
+```typescript
+// src/app/api/token-market-data/route.ts
+export async function GET(request: NextRequest) {
+  // Fetches token data including:
+  // - Current price
+  // - Price change (24h)
+  // - Market cap
+  // - Trading volume
+  // - Price history
+  // - Token holders
+}
+```
+
+### 2. Custom Hook (`useTokenMarketData`)
+
+A React hook that manages the fetching and caching of token market data:
+
+```typescript
+// src/app/hooks/useTokenMarketData.ts
+export function useTokenMarketData(tokenAddress: string | null) {
+  // Returns: { data, loading, error }
+}
+```
+
+### 3. Price Chart Component
+
+A lightweight SVG-based chart component that visualizes token price history:
+
+```typescript
+// src/app/components/PriceChart.tsx
+export function PriceChart({ 
+  data, 
+  height = 120, 
+  showGrid = true 
+}: PriceChartProps)
+```
+
+Features:
+- Responsive SVG rendering
+- Green/red color coding for positive/negative trends
+- Gradient fill for visual appeal
+- Grid lines for better readability
+
+### 4. Enhanced Token Card
+
+The swipe mode token cards now display:
+
+#### Header Section
+- Token icon with backdrop blur effect
+- Price chart overlay in the background
+- Token symbol and name
+
+#### Price Information
+- Current price (up to 6 decimal places)
+- 24-hour price change with color coding
+- Portfolio balance and USD value
+
+#### Market Data Section
+- Market capitalization (formatted with K/M/B suffixes)
+- 24-hour trading volume
+- Number of token holders
+
+## Visual Design
+
+The updated token cards feature:
+- **Gradient Background**: Blue to purple gradient with price chart overlay
+- **Glassmorphism**: Semi-transparent elements with backdrop blur
+- **Color Coding**: Green for positive changes, red for negative
+- **Data Hierarchy**: Most important information (price, value) prominently displayed
+
+## Data Flow
+
+1. User enters swipe mode
+2. For each token card rendered:
+   - `useTokenMarketData` hook is called with token address
+   - Hook fetches data from `/api/token-market-data`
+   - API route queries Zapper XYZ GraphQL endpoint
+   - Data is returned and displayed on the card
+3. Price chart renders historical data
+4. Market metrics update in real-time
+
+## Benefits for Users
+
+1. **Informed Decisions**: See price trends before deciding to keep or sell
+2. **Market Context**: Understand token performance with market cap and volume
+3. **Visual Insights**: Quick price trend recognition through charts
+4. **Comprehensive Data**: All relevant token information in one view
+
+## Configuration
+
+Ensure the following environment variable is set:
+```
+ZAPPER_API_KEY=your_zapper_api_key_here
+```
+
+## Future Enhancements
+
+1. **Extended History**: Show different timeframes (1D, 1W, 1M)
+2. **Technical Indicators**: Add moving averages or RSI
+3. **Social Metrics**: Include social sentiment data
+4. **Price Alerts**: Notify users of significant price movements
+5. **Comparison Mode**: Compare multiple tokens side by side
+
+## Error Handling
+
+The integration includes graceful fallbacks:
+- If Zapper API fails, basic token data is still displayed
+- Mock price history is generated for demonstration
+- Loading states indicate when data is being fetched
+- Error states are handled without breaking the UI
+
+## Performance Considerations
+
+- Data is fetched on-demand per token
+- API responses are cached to reduce redundant calls
+- Lightweight chart component with no external dependencies
+- Optimized for mobile performance
