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

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

Instructions

Step 1: Navigate to Scripts Directory


cd ${CLAUDE_SKILL_DIR}/scripts

Step 2: Choose a Command

View pending transactions: python mempool_analyzer.py pending
Analyze gas prices: python mempool_analyzer.py gas
Detect pending DEX swaps: python mempool_analyzer.py swaps
Scan MEV opportunities: python mempool_analyzer.py mev
Get mempool summary: python mempool_analyzer.py summary
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

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 (--format json)

Error Handling

Examples

Example 1: Check gas before sending transaction:

          How It Works
          The mempool agent automatically activates when you discuss:

Mempool analysis and pending transactions
MEV opportunities and extraction strategies
Gas price optimization
Front-running and sandwich attack detection
Large transaction monitoring

Example Queries

What MEV opportunities are currently in the mempool?
