What it means
Maximal extractable value — the profit that can be taken by choosing which transactions go into a block and in what order.
Why it matters when you trade
Whoever orders transactions holds an option on everyone else's. That option is worth money, and the market for it is competitive and industrial. MEV is not only predatory: arbitrage and liquidations are also MEV and both are necessary. What matters to a trader is that ordering is an economic market, not a queue, and that your transaction competes in it.
Worked example
A liquidation worth $40,000 in bonus draws bots bidding priority fees up to nearly $40,000 to be the one that captures it.
See it on live markets
DexLadder runs mev against live market and pool data, with simulated capital, so you can watch it act on an order instead of reading about it — no account, no wallet, nothing installed.
