MEV Relay (For Validators)

Node operators should set up MEV-Boost to connect to bloXroute MEV relay.

Setup MEV-Boost

Please refer to mev-boost usage instructions and a full set of setup instructions in the testing guide on GitHub.

Mev-boost is available on Github or Docker Hub.

Relay Types

bloXroute hosts two types of MEV relays, Max profit and Regulated, that validators and builders can connect to. Both two relays currently propagate all available transactions/bundles except the ones that interacted with addresses sanctioned by OFAC, and they have the same filtering requirement, although for legacy reasons, bloXroute still maintains the two relay names in parallel.

Relay Endpoints

Ethereum Mainnet Validators

Validators with mev-boost can connect to the ETH Mainnet bloXroute MEV relay to receive full blocks proposed by bloXroute. Validators are able to choose one of the MEV relay types and add it to mev-boost -relays startup argument:

• Max profit relay: https://0x8b5d2e73e2a3a55c6c87b8b6eb92e014[e-mail]

• Regulated relay: https://0xb0b07cd0abef743db4260b0ed50619cf[e-mail]

Validators can append ?id= parameter to the end of relay URL. For example:

./mev-boost -mainnet -relays https://0x8b5d2e73e2a3a55c6c87b8b6eb92e014[e-mail]?id=validator-name

It is recommended to connect to both Flashbots relay and bloXroute relay.

Validators can also append a ?skip_optimism=true parameter to the end of a relay URL when connecting to a bloXroute relay, to require that all blocks are simulated before being served headers for them. By default, trusted builders who have a relationship with bloXroute are not simulated. An example of appending this parameter would look like:

./mev-boost -mainnet -relays https://0x8b5d2e73e2a3a55c6c87b8b6eb92e014[e-mail]?id=validator-name&skip_optimism=true

Holesky Testnet Validators

Validators with mev-boost can connect to the bloXroute MEV relay in order to receive full blocks proposed by bloXroute:

• https://0x821f2a65afb70e7f2e820a925a9b4c80[e-mail]

Validators can append ?id= parameter to the end of relay URL. For example:

./mev-boost -genesis-fork-version 0x01017000 -relays https://0x821f2a65afb70e7f2e820a925a9b4c80[e-mail]?id=validator-name
