RecoveryDex - Multi-Split Token Swap Aggregator

RecoveryDex is a comprehensive DeFi platform that combines smart contract aggregation with an intuitive React frontend. The project implements intelligent token swapping on the Harmony network, allowing users to split large transactions (amountIn) into multiple smaller operations using intermediate tokens like JEWEL, SONIC, or VIPER to minimize slippage.

🌟 Features

• Multi-Split Aggregation: Automatically splits large trades into smaller chunks to reduce slippage
• Router Optimization: Finds the best routes across multiple DEX routers
• Intermediate Token Support: Uses whitelisted intermediate tokens for optimal routing
• React Frontend: Modern, responsive web interface with wallet integration
• Documentation Site: Comprehensive VitePress-powered documentation
• Harmony Network: Optimized for Harmony blockchain with WONE support

🚀 Installation

Install project dependencies:

# Install smart contract dependencies
npm install

# Install frontend dependencies (if running separately)
cd src && npm install

💻 Usage

Smart Contract Development

Deploy contracts to Harmony network:

# Deploy to Harmony mainnet
npm run deploy

# Deploy to Harmony testnet  
npm run deploy:testnet

Run contract simulations:

# Simulate on mainnet
npm run simulate

# Simulate on testnet
npm run simulate:testnet

Run tests:

Frontend Development

The frontend is configured to run with Vite and includes:

# Start development server (configured in vite.config.js)
npm run dev  # Runs on port 3007 by default

# Build for production
npm run build

# Preview production build
npm run preview

Documentation

Generate and serve documentation:

cd docs
npm run dev     # Development server
npm run build   # Build static site
npm run preview # Preview built site
