Flashbots

Develops PBS-based MEV solutions for Ethereum

Overview

Flashbots conducts research and development to address Maximal Extractable Value (MEV) in stateful blockchains, starting with Ethereum. It builds tools and infrastructure that let validators participate in an open market for blockspace by selling blocks to builders, supported by proposer-builder separation (PBS) in Ethereum’s proof-of-stake system. The product works by enabling a permissionless, transparent market where builders propose blocks and validators select which block to publish, helping to maximize staking rewards while mitigating MEV’s negative effects and reducing concentration of power. The company differentiates itself by focusing specifically on MEV mitigation and PBS-enabled blockspace markets, providing the technical ecosystem for validators, developers, and miners to operate efficiently and fairly. Its goal is to create a sustainable, fair, and transparent MEV ecosystem that distributes rewards more broadly and minimizes harmful externalities.
