SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Solving MEV-related risks for Solidity protocols by providing patterns and defenses against transaction-ordering exploitation in swaps, auctions, and NFT mints.

Core Features & Use Cases

  • Sandwich-attack defenses for AMMs to prevent front-run and back-run sequences.
  • Commit-reveal schemes for auctions and mints to deter opportunistic bidding.
  • Private mempool / Flashbots guidance to reduce exposure to frontrunners.
  • Slippage protection and deadline parameters to protect users from reordering.
  • Real-world scenario: design a token swap that minimizes MEV exposure and preserves fair pricing during peak traffic.

Quick Start

Integrate MEV defense patterns into your Solidity protocol to mitigate front-running and ensure fair execution.

FAQPage Schema
How do I prevent sandwich attacks in my Solidity AMM swap contracts?▼

To prevent sandwich attacks in Solidity AMMs, implement slippage protection parameters and deadline checks to reject transactions that execute at unfavorable prices due to front-running and back-run sequences.

What is the best way to stop front-running in NFT mint and auction contracts?▼

The best way to stop front-running in NFT mints and auctions is implementing commit-reveal schemes, which separate the bidding commitment phase from the reveal phase to deter opportunistic transaction ordering.

How do I integrate Flashbots or private mempools to reduce MEV exposure?▼

Integrate Flashbots or private mempools to route transactions directly to miners, bypassing the public mempool where front-running bots monitor and exploit pending transaction ordering.

Does my decentralized application need slippage protection and deadline parameters?▼

Yes, slippage protection and deadline parameters are essential for transaction-ordering-dependent logic across decentralized applications, ensuring users are protected from price reordering exploitation during peak network traffic.

When should I use commit-reveal schemes versus private mempools for MEV defense?▼

Use commit-reveal schemes for auctions and NFT mints to hide bid details, while private mempools and Flashbots are better suited for AMM swaps to prevent transactions from being visible to front-runners.
