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.
