Flashbots Relay

Architecture

Flashbots Relay represents a specialized transaction relay network designed to mitigate Miner Extractable Value (MEV) within the Ethereum ecosystem. Its core function involves receiving, sequencing, and broadcasting transactions in a manner that aims to level the playing field between searchers and validators, reducing frontrunning and sandwich attacks. The system operates as a private order flow auction, allowing searchers to submit transaction bundles which are then evaluated and executed based on criteria prioritizing fairness and efficiency, rather than solely maximizing validator profit. This infrastructure directly impacts market microstructure by altering incentive structures and influencing the cost of transaction execution.
