MEV Shield User Manual

Complete guide to protecting your blockchain transactions from Maximal Extractable Value (MEV) attacks using MEV Shield's enterprise-grade protection platform.

Introduction

MEV Shield is a comprehensive platform designed to detect, analyze, and protect against MEV attacks on blockchain networks. MEV (Maximal Extractable Value) refers to the profit that can be extracted by reordering, inserting, or censoring transactions within a block.

What is MEV?

MEV attacks include frontrunning, sandwich attacks, and arbitrage exploits that can cost traders significant amounts. MEV Shield monitors the mempool and blockchain to detect these attacks before they impact your transactions.

Key Capabilities

Quick Start Guide

Step 1: Access the Dashboard

Navigate to mevshield.ai to access the MEV Shield dashboard. No account is required for basic monitoring features.

Step 2: View Real-Time Statistics

The dashboard displays real-time MEV detection statistics including:

Step 3: Monitor Your Addresses

Add wallet addresses to monitor for MEV-targeted transactions. You'll receive alerts when suspicious activity is detected.

Dashboard Overview

Statistics Panel

Displays aggregate statistics including total MEV detected, protected value, and attack counts across all monitored chains.

Recent Alerts

Live feed of detected MEV activity with severity indicators, affected addresses, and estimated impact.

Chain Status

Real-time health indicators for each supported blockchain showing connection status, block height, and mempool size.

MEV Detection

MEV Shield continuously monitors the mempool and blockchain for MEV patterns. Detection algorithms analyze:

Detection Metrics

Metric Description
Confidence Score Probability (0-100%) that detected activity is MEV
Estimated Profit Calculated MEV profit extracted from the attack
Victim Loss Estimated loss suffered by the target transaction

Transaction Protection

MEV Shield provides multiple protection mechanisms:

Flashbots Protect

Transactions are routed through Flashbots Protect to prevent frontrunning. This ensures your transaction is only included if it can execute at your specified price or better.

// Example: Submit protected transaction
POST /api/protect
{
  "from": "0x...",
  "to": "0x...",
  "data": "0x...",
  "value": "1000000000000000000",
  "maxFeePerGas": "50000000000"
}

Private Mempool

For high-value transactions, MEV Shield can route through private mempools that are not visible to MEV searchers.

Multi-Chain Monitoring

MEV Shield monitors the following chains:

Chain Block Time Coverage
Ethereum 12 seconds Full mempool + block analysis
Polygon 2 seconds Block analysis
BSC 3 seconds Block analysis
Arbitrum 0.25 seconds Sequencer + block analysis
Optimism 2 seconds Sequencer + block analysis
Base 2 seconds Sequencer + block analysis

Alert System

Configure alerts based on various triggers:

API Access

MEV Shield provides a comprehensive REST API for programmatic access:

// Get live MEV statistics
GET /api/live/stats

// Get recent alerts
GET /api/live/alerts

// Get chain status
GET /api/live/chains

// Get exchange integration status
GET /api/live/exchanges

See the Exchange Integration API for detailed API documentation.

Flashbots Integration

MEV Shield integrates with Flashbots to provide frontrunning protection on Ethereum mainnet.

How Flashbots Works

Flashbots is a research and development organization working on mitigating MEV. Their "Flashbots Protect" RPC routes transactions through a private channel directly to block builders, bypassing the public mempool.

Risk Assessment

Get MEV risk scores for any trading pair before executing trades:

GET /api/live/exchanges/binance/risk/ETH-USDT

Response:
{
  "pair": "ETH-USDT",
  "riskScore": 42,
  "riskLevel": "medium",
  "factors": [
    "High liquidity reduces sandwich risk",
    "Moderate slippage expected",
    "Active arbitrage bots detected"
  ]
}

MEV Attack Types

Frontrunning

Attacker sees your transaction in mempool and submits the same trade with higher gas to execute first, profiting from your expected price impact.

Sandwich Attack

Attacker places transactions before AND after your trade, manipulating the price both ways to extract value.

Liquidation Hunting

Searchers monitor lending protocols for positions near liquidation threshold and front-run to claim liquidation bonuses.

Arbitrage

While not always harmful, cross-DEX arbitrage can indicate price inefficiencies being exploited.

Supported Chains

MEV Shield provides full support for the following EVM-compatible chains:

Troubleshooting

Common Issues

Connection Issues

If the dashboard shows "Disconnected", ensure you have a stable internet connection and try refreshing the page. The system will automatically reconnect.

Missing Alerts

Alerts are filtered by severity. Check your alert threshold settings if you're not seeing expected notifications.
