Why MEV Shield?

🛡

User Protection

Shield your users from sandwich attacks, frontrunning, and MEV extraction. Private transaction submission via Flashbots Protect keeps your users safe.

MEV Rebates

Don't just block MEV — capture and redistribute it. The rebate router returns extracted value to your users, turning MEV from a tax into a feature.

Gas-Free UX

ERC-4337 paymaster funded by MEV rebates. Your users get gas-sponsored transactions while the protocol earns from orderflow auctions.

🔍

Full Visibility

Real-time mempool monitoring, block-by-block MEV scanning, and orderflow analytics dashboard. Know exactly what's happening to your protocol's transactions.

🤖

Searcher Tools

Build your own MEV searching operations. Arbitrage detection, liquidation monitoring, and backrunning framework with profit tracking and bundle submission.

🔧

Dual Language

FAQ

What types of MEV does this detect?

The Sandwich Detector and MEV Monitoring Agent identify sandwich attacks, front-running, back-running, and JIT (just-in-time) liquidity extraction. Real-time mempool scanning catches threats before they land on-chain.

Does it work with Flashbots?

Yes — the MEV-Share SDK integrates directly with Flashbots MEV-Share for orderflow auctions, and the Private Tx Relay submits transactions via Flashbots Protect with fallback strategies.

What chains are supported?

MEV protection tools are primarily designed for Ethereum mainnet where MEV is most relevant. Some tools (Searcher Starter Kit, EIP-712 Signing Library) work on any EVM chain including L2s.

Are the contracts audited?

Every contract includes comprehensive Foundry test suites (unit, fuzz, and invariant tests) and detailed security notes. We recommend a professional audit before mainnet deployment.

What license are the products under?

All products are MIT licensed. You can use, modify, and distribute them in commercial projects without restriction.

What support is included?

The Pro Bundle includes 30 days of priority support. Individual product purchases are supported through our community channels. All products include documentation and examples.
