Configure MEV aka Proposer Builder Separation

Proposer Builder Separation

MEV Boost

Your Consensus Layer client connects to the mev-boost container. If you are running a CL in Eth Docker, then in .env you'd add mev-boost.yml to COMPOSE_FILE, set MEV_BOOST=true and set MEV_RELAYS to the relays you wish to use.

Commit Boost

This is an alternative to MEV Boost. Your Consensus Layer client connects to the cb-pbs container. If you are running a CL in Eth Docker, then in .env you'd add commit-boost-pbs.yml to COMPOSE_FILE, set MEV_BOOST=true and set MEV_NODE=http://cb-pbs:18550.

Next, edit commit-boost/cb-config.toml and configure the relays you'd like to use.

Verify

If you would like to verify whether your MEV relay has registered your validator, follow the documentation for your chosen relays. For instance, if you have included Flashbots, you can see whether your validator has been registered by querying their API. Add your validator's public key to the end of this endpoint: https://boost-relay.flashbots.net/relay/v1/data/validator_registration?pubkey=

Just a VC, example RocketPool

If you are running a validator client only, such as with a RocketPool "reverse hybrid" setup, then all you need to do is to set MEV_BOOST=true in .env. mev-boost.yml and MEV_RELAYS are not needed and won't be used if they are set, as they are relevant only where the Consensus Layer client runs. See the Overview drawing for how these components communicate.
