This repository provides a "boost" implementation that serves the [builder-specs APIs] connecting validators to an external block builder network.

Warning: this software is extremely experimental. You should not use in any production capacity.


Build from source

The best way to use this right now is to build from source.

Run mev-boost-rs

You'll need to construct a configuration file like the example.config.toml found at the root of this directory.

For example, this configuration

host = ""
port = 18550
relays = [

instructs mev-boost-rs to run on localhost on port 18550 and only use the Flashbots relay running on the sepolia testnet.

Then, to run for sepolia:

mev --network sepolia boost example.config.toml
