MEV-Boost in a Nutshell

MEV-Boost is an implementation of proposer-builder separation (PBS) built by Flashbots for proof of stake Ethereum. Validators running MEV-Boost maximize their staking reward by selling blockspace to an open market of builders.

MEV-Boost is free, open-source, neutral software built with love, for the community. For information on MEV-Boost software and roadmap, see the MEV-Boost Repository.

Quickstart​

  1. Install the latest version of MEV-Boost

  2. Connect MEV-Boost to desired MEV-Boost relays:

./mev-boost -mainnet -relay-check -relays relay1,relay2
tip

Remember to use the appropriate network flag for the specific network and relay URL, e.g. -mainnet, -sepolia, -holesky or -hoodi.

  1. Configure a consensus client. Detailed instructions are available on the MEV-Boost testing wiki, and guides for connecting the client to MEV-Boost can be found in the consensus client compatibility section.

  2. Confirm that the setup works by calling the Relay Data API to see your validator registration.
