Flash-Profit-Extractor: Reactive Smart Contract Arbitrage Platform

Overview

A novel arbitrage platform built on Reactive Network that optimizes trading strategies through dynamic pricing and automated approval-based swaps. The system leverages reactive smart contracts to enable efficient token swapping and real-time price monitoring.

1. MySwap Contract

The foundation of our platform's swap functionality, implementing approval-based token exchanges.

contract MySwap is IApprovalClient {
    ApprovalService private service;
    IERC20 private token0;
    IERC20 private token1;
    
    uint256 public reserve0;
    uint256 public reserve1;
    uint256 private constant PRECISION = 1e18;
    uint256 public currentPrice;
    
    // Key events for tracking swaps and liquidity
    event LiquidityAdded(address indexed provider, uint256 amount0, uint256 amount1);
    event Swap(address indexed user, uint256 amountIn, uint256 amountOut, address tokenIn, address tokenOut);
    event Result(address indexed user, address tokenOut, uint256 amountOut);

Key Features:

• Reactive Network approval service integration
• Automated price calculations
• 0.3% swap fee mechanism
• Real-time reserve management
• Liquidity provider functionality

2. DynamicPriceERC20 Contract

Implements dynamic token pricing to simulate real market conditions.

contract DynamicPriceERC20 is ERC20 {
    uint256 public mintPrice;    
    uint256 public maxSupply;    
    uint256 public mintIncrease; 
    uint256 public burnDecrease; 
    
    event TokensMinted(address indexed to, uint256 amount, uint256 price);
    event TokensBurned(address indexed from, uint256 amount, uint256 price);
    event PriceUpdated(uint256 newPrice);

Features:

• Dynamic price adjustment based on supply and demand
• Square root pricing model for realistic market simulation
• Mintable and burnable token mechanics
• Price update events for real-time tracking

3. MyExch Contract

Handles token-to-ETH exchanges using the Reactive Network's approval system.

contract MyExch is IApprovalClient {
    ApprovalService private service;
    IDynamicPriceERC20 private immutable token;
    
    // Exchange functionality through approval service
    function onApproval(
        address approver,
        address approved_token,
        uint256 amount
    ) external onlyService {
        // Exchange implementation
    }

Features:

• Direct token-to-ETH conversion
• Reactive approval service integration
• Dynamic pricing integration
• Automated settlement system
