MEV

DeFi

Miner/Maximal Extractable Value from ordering.

MEV is value extracted from transaction ordering within blocks (or bundles). Research explores auction mechanisms (PBS, SUAVE), fair ordering, and protections for users. Roles include research, data, and infra work.

Frequently asked questions

  • How is MEV extracted?
    By reordering, inserting, or censoring transactions within blocks. Builders search for profitable opportunities like arbitrage or liquidations.
  • What is PBS?
    Proposer‑Builder Separation separates block construction from proposing to reduce centralization pressure and manage MEV via auctions and relays.
  • How can users protect themselves?
    Use private mempools/relays, set slippage carefully, and prefer protocols with MEV‑aware designs or protections.
