Learn how to protect your DEX trades from MEV attacks with MEV Shield.

🛡 What is MEV Shield?

MEV Shield protects your decentralized exchange (DEX) trades from Maximal Extractable Value (MEV) attacks, including front-running, sandwich attacks, and other forms of value extraction.

Front-Running Protection

Your transactions are hidden from MEV bots until they're included in a block.

Sandwich Attack Prevention

Prevents attackers from placing orders before and after your trade.

Private Mempool

Transactions routed through Flashbots Protect for maximum privacy.

Multi-Chain Support

Works on Ethereum, Polygon, Arbitrum, Optimism, and Base.

⚡ Quick Start

Get protected in under 2 minutes with these simple steps:

Step 1: Connect Your Wallet

Visit our signup page and connect your MetaMask wallet. No email or personal information required.

Step 2: Approve Connection

Click "Connect" in your MetaMask popup to authorize the connection.

Step 3: Start Trading

Your trades are now protected! Use our RPC endpoint for additional protection.

That's it! Your wallet is now registered for MEV protection. All transactions through our platform are automatically shielded.

🔐 How It Works

MEV Shield uses multiple layers of protection to keep your trades safe:

  1. Transaction Encryption: Your transaction details are encrypted before leaving your device.
  2. Private Mempool Routing: Transactions are sent through Flashbots Protect, bypassing the public mempool.
  3. Block Builder Selection: We work with trusted block builders who don't engage in MEV extraction.
  4. Slippage Optimization: Smart slippage settings prevent unnecessary value leakage.

Privacy First: We never store your transaction data. All processing happens in memory and is discarded after execution.

💳 Wallet Connection

MEV Shield supports connection through:

  • MetaMask - Browser extension and mobile app
  • WalletConnect - Connect any compatible mobile wallet
  • Coinbase Wallet - Browser extension and mobile
  • Rainbow - Mobile wallet with WalletConnect

Privacy Guarantee

When you connect your wallet, we:

  • Hash your wallet address using SHA-256 (never stored in plain text)
  • Only display masked addresses (e.g., 0x1234****5678)
  • Never share your data with third parties
  • Don't require any personal information
