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

1. Install Python 3.8+ with requests library
2. Configure Ethereum RPC URL (default: public endpoint, or set ETH_RPC_URL)
3. Verify internet access for RPC calls

Instructions

Step 1: Navigate to Scripts Directory

cd ${CLAUDE_SKILL_DIR}/scripts

Step 2: Choose a Command

1. View pending transactions: python mempool_analyzer.py pending
2. Analyze gas prices: python mempool_analyzer.py gas
3. Detect pending DEX swaps: python mempool_analyzer.py swaps
4. Scan MEV opportunities: python mempool_analyzer.py mev
5. Get mempool summary: python mempool_analyzer.py summary
6. Watch specific contract: python mempool_analyzer.py watch 0x7a250d...

Alternatively, customize with flags:

python mempool_analyzer.py pending --limit 100    # Limit results
python mempool_analyzer.py --chain polygon gas     # Use different chain
python mempool_analyzer.py --chain arbitrum pending # Or use Arbitrum

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
