Guide to MEV (Maximal Extractable Value) — sandwich attacks, frontrunning, backrunning, and how to protect transactions. Use when explaining MEV to users, recommending swap protection, or analyzing suspicious transaction patterns.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# MEV Protection Guide MEV (Maximal Extractable Value) is profit that block builders and searchers extract by reordering, including, or excluding transactions. Understanding MEV helps protect your users' trades. ## Types of MEV ### 1. Sandwich Attacks The most common MEV attack on DEX swaps: ``` 1. Attacker sees your swap in mempool 2. Attacker buys before you (frontrun) → pushes price up 3. Your swap executes at a worse price 4. Attacker sells after you (backrun) → profits from the price difference ``` **Who gets hurt**: Anyone swapping on DEXs with high slippage tolerance **Typical loss**: 0.3–2% of trade value ### 2. Frontrunning A searcher copies your profitable transaction and submits it first with higher gas: - Arbitrage opportunities - NFT mints - Liquidation calls ### 3. Backrunning Searcher submits a transaction immediately after yours to capture resulting arbitrage: - After large swaps (price impact creates arb opportunity) - After oracle updates - After liquidations ### 4. Just-In-Time (JIT) Liquidity A sophisticated attack on V3 pools: 1. Searcher adds concentrated liquidity just before your swap 2. Your swap pays fees to the searcher's position …

How to install
mdr add nirholas/three.ws/mev-protection-guide@sha256:b1f15c72c860eda6The line at the top of this page pins the label git:20260501.87cefc9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
