Our review

This guide covers miner extractable value (MEV) concepts, common attacks like sandwich and frontrunning, and mitigation strategies.

Strengths

  • Provides a clear list of MEV attack types and countermeasures
  • Offers precise locations for organizing resources in a README
  • Includes links to up-to-date external data sources

Limitations

  • Does not go into deep implementation details of mitigations
  • Focused on Ethereum and compatible chains, less applicable elsewhere
When to use it

Use this guide when documenting MEV risks and security best practices for a DeFi application.

When not to use it

Avoid this guide if you need a hands-on, step-by-step tutorial on coding a specific mitigation.

Security analysis

Safe
Quality score80/100

This skill is purely educational, providing guidance on MEV concepts and resource organization. It contains no executable instructions, no dangerous commands, and does not instruct any data exfiltration or system modifications.

Examples

List MEV attack types
Explain the main types of MEV attacks including sandwich, frontrunning, and backrunning, and suggest mitigations for each.
Organize MEV section in README
Help me structure a MEV security section in my project's README. Include subheadings for concepts, attacks, and mitigations, and suggest where to place links to external resources.
MEV mitigation RPCs
List private transaction relays and MEV-blocking RPC endpoints that developers can use to protect users from MEV exploitation.

MEV Security

Scope

Use this skill for:

  • MEV concepts and threat models
  • Sandwich/frontrunning/backrunning patterns
  • Mitigations and private transaction relays

Concepts (Quick List)

  • Transaction ordering and block building
  • Sandwich attacks
  • Arbitrage and liquidation extraction
  • Private order flow / private mempool

Mitigations

  • Private transaction relays / RPC endpoints
  • MEV blockers
  • Commit-reveal patterns (where applicable)
  • Slippage protection and simulation

Where to Add Links in README

  • MEV concept resources: DeFi Topics → MEV
  • MEV defense tooling (RPC/relays): DeFi Topics → MEV (primary), optionally Development → Tools only if the link is a general-purpose dev tool

Rules

  • English descriptions
  • No duplicates
