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
