Open-source middleware for Ethereum validators to access a competitive block-building market via proposer-builder separation.
Latest: v1.12Plug & Play
Compatible with all Ethereum consensus clients. Install, configure your relays, and start earning maximum rewards.
Builder Market
Access blocks from a competitive marketplace of builders who optimize for MEV extraction and fair reward distribution.
Open & Neutral
Free, open-source, and audited software. Run by thousands of validators to promote decentralization and censorship resistance.
Quickstart
-
Connect MEV-Boost to desired relays:
./mev-boost -mainnet -relay-check -relays relay1,relay2
Use the appropriate network flag: -mainnet, -sepolia, or -hoodi.
-
Configure your consensus client. See the consensus client compatibility table for guides.
-
Verify your setup by calling the Relay Data API to check your validator registration.
