MEV is one of the most misunderstood parts of DeFi. Here is a clear, non-alarmist explanation of what it is today. In this piece we walk through the key points a professional investor would consider before drawing conclusions.
The definition, simply
Maximal extractable value is the value that can be captured by ordering transactions in a block. It is a natural consequence of having open mempools and permissionless block-building. It is neither good nor bad in itself.
The types that matter for users
Sandwich attacks on retail swaps are the type of MEV that most directly harms individual users. Arbitrage across venues, by contrast, is a form of MEV that actually helps keep prices consistent and benefits users indirectly.
Practical protections
Modern wallets and DEXes increasingly route through MEV-protected channels, quietly reducing the impact of sandwich attacks. Users can also lower their slippage tolerance, use limit orders where available and split large trades into smaller pieces.
Where the industry is going
The direction of travel is toward more transparent, more competitive block-building markets and better user-side protections. That will not eliminate MEV, but it will reduce the share of it that ends up as a hidden tax on ordinary users.
