MEV Overview

Maximal Extractable Value (MEV) allows validators to earn additional rewards by including optimally ordered transactions in blocks.

Important

MEV-Boost is optional but recommended for validators who want to maximize rewards.

How it works:

  1. Block Builders - Create optimized blocks with MEV

  2. Relays - Connect validators to builders

  3. MEV-Boost - Sidecar that requests blocks from relays

  4. Proposer - Your validator proposes the winning block
