Value that can be extracted by controlling the order, inclusion, or exclusion of transactions in a block.
Observe mempool
Pending transactions are visible before they're included in a block.
Simulate outcomes
Searchers simulate how reordering or inserting transactions around a pending one would change the result.
Bid for placement
Searchers bid (often via private relays) for their transaction to be placed favorably by the block builder.
Block inclusion
The builder/validator includes the ordered bundle of transactions in the next block.
Whoever decides the order of transactions in a block can profit from that ordering - for example, by placing their own trade immediately before and after a large pending trade (a 'sandwich').
This is a well-studied, adversarial part of public blockchains. It's a core reason DEX users are advised to set a minimum-received / slippage limit on every trade.

Does this app perform MEV extraction for me?
No. This page is educational only. This app does not run any bots, searchers, or private-relay bundles.
