# Analyzing Mempool

## Overview

Monitor Ethereum mempool for pending transactions, analyze gas prices, detect DEX swaps, and identify potential MEV opportunities. Useful for traders, MEV researchers, and protocol developers.

## Prerequisites

Before using this skill, ensure you have:
- Python 3.8+ with requests library
- Ethereum RPC URL (default: public endpoint, or set ETH_RPC_URL)
- Internet access for RPC calls

## Instructions

### Step 1: Navigate to Scripts Directory

```bash
cd {baseDir}/scripts
```

### Step 2: Choose Your Command

**View Pending Transactions:**
```bash
python mempool_analyzer.py pending
python mempool_analyzer.py pending --limit 100
```

**Gas Price Analysis:**
```bash
python mempool_analyzer.py gas
# Shows distribution, recommendations for slow/standard/fast/instant
```

**Pending DEX Swaps:**
```bash
python mempool_analyzer.py swaps
# Detects Uniswap, SushiSwap, 1inch pending swaps
```

**MEV Opportunity Scan:**
```bash
python mempool_analyzer.py mev
# Detects sandwich, arbitrage, liquidation opportunities
```

**Mempool Summary:**
```bash
python mempool_analyzer.py summary
# Quick overview of pending count, gas, opportunities
```

**Watch Specific Contract:**
```bash
python mempool_analyzer.py watch 0x7a250d...
# Monitor pending transactions to specific contract
```

### Step 3: Interpret Results

**Gas Recommendations:**
- Slow (10th percentile): May take 10+ blocks
- Standard (50th percentile): 2-5 blocks
- Fast (75th percentile): 1-2 blocks
- Instant (90th percentile): Next block likely

**MEV Warnings:**
- MEV detection is for educational purposes
- Real MEV extraction requires specialized infrastructure
- Use this for research and understanding mempool dynamics

## Output

- Pending transaction lists with gas prices and types
- Gas price distribution and recommendations
- Detected DEX swaps with amounts and DEX identification
- MEV opportunity analysis with estimated profits
- JSON output for programmatic use
