Advanced mempool analysis for MEV opportunities, pending transaction monitoring, and gas price optimization.
Features
- Real-time mempool monitoring across Ethereum, BSC, Polygon, and Arbitrum
- MEV opportunity detection including sandwich attacks, arbitrage, and liquidations
- Gas price optimization with EIP-1559 base fee prediction
- Transaction analysis with calldata decoding and simulation
- Block builder monitoring to understand validator MEV extraction
- Risk assessment for detected opportunities
Installation
/plugin install mempool-analyzer@claude-code-plugins-plus
Usage
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?
Show me all pending large ETH transfers over $1M
What's the optimal gas price for the next block?
Analyze pending Uniswap swaps for arbitrage opportunities
Monitor address 0x... for incoming mempool transactions
Configuration
Create a .mempool-config.json file:
{
"networks": ["ethereum", "bsc", "polygon", "arbitrum"],
"rpcEndpoints": {
"ethereum": "wss://eth-mainnet.g.alchemy.com/v2/YOUR_KEY"
},
"mevDetection": {

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
cd {baseDir}/scripts
Step 2: Choose Your Command
View Pending Transactions:
python mempool_analyzer.py pending
python mempool_analyzer.py pending --limit 100
Gas Price Analysis:
python mempool_analyzer.py gas
# Shows distribution, recommendations for slow/standard/fast/instant
Pending DEX Swaps:
python mempool_analyzer.py swaps
# Detects Uniswap, SushiSwap, 1inch pending swaps
MEV Opportunity Scan:
python mempool_analyzer.py mev
# Detects sandwich, arbitrage, liquidation opportunities
Mempool Summary:
python mempool_analyzer.py summary
# Quick overview of pending count, gas, opportunities
Watch Specific Contract:
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
