What Role Do ‘Searchers’ Play in the MEV Ecosystem?

Searchers are specialized actors, often sophisticated bots, that monitor the public mempool for profitable MEV opportunities, such as arbitrage, liquidations, or front-running. They construct transaction bundles that capture this value and submit them to block builders or validators, often through private relays like Flashbots, in exchange for a fee (a bribe).
