1SwapDash

1SWAPDASH is a comprehensive multi-chain DeFi dashboard that maximizes 1inch API integration to provide users with advanced trading capabilities, portfolio analytics, and real-time market insights.

KEY FEATURES: • Complete 1inch API Coverage: Integrates 10+ 1inch APIs including Swap, Portfolio, Fusion, Spot Price, History, Charts, NFT, Domains, Web3 RPC, and Orderbook APIs • Multi-Chain Portfolio Analytics: Real-time portfolio tracking across Ethereum, BSC, Polygon, Arbitrum, Optimism, Base, and Linea • Advanced Trading: Classic swaps, Fusion trading with MEV protection, and access to 100+ liquidity sources • Interactive Charts: Portfolio value visualization with Recharts (Area/Line charts, multiple timeframes) • Real-Time Data: Live token prices, network statistics, gas monitoring, and block information • Professional UI: Modern interface built with shadcn/ui components and FontAwesome icons

🎯 HACKATHON ALIGNMENT: This project directly addresses the "Build a full Application using 1inch APIs" track by demonstrating extensive API integration across all major 1inch services. The application showcases real-world usage of Portfolio API v4/v5, Fusion API, Spot Price API, History API, Charts API, Web3 RPC API, and more.

LIVE FEATURES: • Wallet integration via RainbowKit (MetaMask, WalletConnect, Coinbase) • Real-time balance tracking with USD values • Token swapping with best-rate aggregation • Transaction history with Etherscan integration • CSV portfolio export functionality • Live price tracking with 30-second updates • Network statistics and gas price monitoring

The dashboard provides a complete DeFi experience while maximizing 1inch's API ecosystem for optimal user experience.

FRONTEND STACK: • React 18 + TypeScript for type-safe development • Vite for lightning-fast development and optimized builds • Tailwind CSS + shadcn/ui for modern, accessible UI components • Recharts for interactive data visualization • FontAwesome for professional iconography

WALLET & BLOCKCHAIN INTEGRATION: • wagmi v2 + RainbowKit for seamless wallet connections • viem for efficient blockchain interactions • Support for 7 major chains (Ethereum, BSC, Polygon, Arbitrum, Optimism, Base, Linea)

1INCH API INTEGRATION (10+ APIs): • Classic Swap API v6.1: Token swapping with best rates • Portfolio API v4/v5: Real-time portfolio analytics and CSV exports • Fusion API: Advanced trading with MEV protection • Spot Price API v1.1: Live token prices with 30-second updates • History API v2.0: Complete transaction tracking • Charts API: Portfolio value visualization • Web3 RPC API: Direct blockchain interaction for network stats • NFT API, Domains API, Orderbook API: Extended functionality

🔧 TECHNICAL INNOVATIONS:

PROXY ARCHITECTURE: • Custom Vite proxy configuration handles CORS and API key injection • Secure environment variable management • Rate limiting implementation to prevent API abuse

REAL-TIME DATA MANAGEMENT: • Custom hooks with 30-second intervals for live updates • Intelligent caching to optimize API calls • Graceful fallbacks when APIs are unavailable

STATE MANAGEMENT: • React hooks for component-level state • Custom hooks for API data fetching (usePortfolio, useBalances, useSwap, etc.) • Optimistic updates for better UX

🎨 UX/UI HIGHLIGHTS:

RESPONSIVE DESIGN: • Mobile-first approach with Tailwind CSS • shadcn/ui components for consistent, accessible UI • Professional color scheme and typography

PERFORMANCE OPTIMIZATIONS: • Vite's HMR for instant development feedback • Code splitting and lazy loading • Optimized bundle size with tree shaking

⚡ NOTABLE HACKS & SOLUTIONS:

API RATE LIMITING: • Built custom rate limiter to handle 1inch API limits • Queue-based request management • Intelligent retry logic with exponential backoff

MULTI-CHAIN DATA AGGREGATION: • Unified portfolio view across all supported chains • Network-specific token handling • Automatic network detection and switching

CHART DATA PROCESSING: • Real-time price data transformation for Recharts • Fallback chart generation when APIs are unavailable • String-to-number conversion for API responses

ERROR BOUNDARY IMPLEMENTATION: • Graceful error handling throughout the application • User-friendly error messages • Automatic fallbacks for missing data

The project demonstrates comprehensive 1inch API utilization while maintaining professional code quality, responsive design, and robust error handling - perfect for the hackathon's "Build a full Application using 1inch APIs" track.
