MEV
MEV (maximal extractable value) is the value that can be captured by controlling transaction inclusion and ordering in a block, such as through arbitrage, liquidations, or front-running strategies.

MEV and Orderflow
These terms describe how ordering affects who captures value and why users may seek protected execution paths.
How to recognize this theme
Terms tied to transaction ordering, block building, and execution quality.
In a daily board, this category groups terms by their shared role. Look for four cards that describe the same mechanism, risk area, or workflow rather than four words that merely sound similar.

Sandwich Attack
A sandwich attack is a form of MEV where an attacker places trades before and after a victim's swap to move the price against the victim and then capture profit when reversing.
Private Mempool
A private mempool is a transaction relay path that avoids broad public gossip, which can reduce exposure to certain MEV attacks but also changes trust and censorship assumptions.
Order Flow Auction
An order flow auction is a mechanism where searchers or builders bid for the right to execute or include a user's order, aiming to improve execution while explicitly pricing ordering privileges.
