AMM Plus Strategy - Yield Optimizer with Arbitrage Detection

📋 Overview

This repository contains an automated market maker (AMM) strategy that implements a yield optimizer with arbitrage detection for the NEAR blockchain ecosystem. The strategy focuses on selling CRANS tokens to obtain other tokens (primarily NEAR/stNEAR) while detecting and exploiting arbitrage opportunities across different liquidity pool routes.

🎯 Strategy Description

Core Concept

• Direction: Sells CRANS tokens to acquire NEAR/stNEAR
• Method: Multi-path arbitrage detection across various LP pairs
• Optimization: Yield maximization through route comparison and selection

Key Components

1. Supervisor (yieldOptimizer.tsx)

The main yield optimization engine that:

• Manages the complete trading cycle
• Handles CRANS token sales across multiple routes
• Coordinates with Ref Finance DEX
• Implements safety mechanisms and cooldown periods
• Tracks and reports profit/loss

2. Arbitrage (arbitrageDetector.tsx)

The arbitrage detection system that:

• Simulates multiple trading routes in real-time
• Compares expected returns across different LP paths
• Identifies the most profitable route
• Validates arbitrage opportunities before execution

🛠 Technical Architecture

Trading Routes

The system evaluates multiple routes for CRANS token sales:

Primary Routes:
- CRANS → NEAR → stNEAR
- CRANS → SHITZU → NEAR → stNEAR
- CRANS → BD → NEAR → stNEAR
- CRANS → SIN → NEAR → stNEAR
- CRANS → PUMP → NEAR → stNEAR

Complex Multi-hop Routes:
- CRANS → SHITZU → BD → NEAR → stNEAR
- CRANS → BD → SHITZU → NEAR → stNEAR

Configuration

• Base Amount: 500 CRANS per trade
• Cooldown: 1-3 minutes between cycles
• Safety Margin: 99.9% slippage protection
• Gas Limit: 300 TGas

🔧 Dependencies

• React: Frontend framework
• NEAR: Priv Keys interaction
• Rhea Finance SDK: DEX integration
• Big.js: Precision arithmetic
• TypeScript: Type safety

🚀 Usage

Prerequisites

• NEAR wallet with CRANS tokens
• Rhea Finance deposit to DEX contract
• Private key configuration

Integration

import { ArbitrageSupervisor } from './yieldOptimizer';
import { CransArbitrage } from './arbitrageDetector';

// Initialize yield optimizer
<ArbitrageSupervisor 
  isEnabled={true}
  onProfit={(profit) => console.log('Profit:', profit)}
  onRouteFound={(route) => console.log('Best route:', route)}
/>

📊 Performance Metrics

The system provides real-time monitoring of:

• Trade execution success rate
• Profit/loss tracking
• Route performance comparison
• Gas usage optimization
• Market conditions analysis

📈 Strategy Logic

1. Balance Check: Verify CRANS token availability
2. Route Simulation: Test all possible trading paths
3. Arbitrage Detection: Identify most profitable route
4. Execution: Execute trades with safety margins
5. Profit Calculation: Track and report returns
6. Cooldown: Wait before next cycle
