MEV Protection Overview

Flashbots Protect is a cheaper and safer way to transact on Ethereum. It protects your transactions from frontrunning and gives you refunds on gas fees and MEV.

Key benefits:

  • Frontrunning protection: Transactions are sent to a private Flashbots mempool where they will be hidden from frontrunning and sandwich bots.
  • Refunds: If your transaction creates MEV, you an earn an MEV refund. If your transaction pays high priority fees, you can earn gas fee refunds.
  • No failed transactions: Transactions are only included in the block if they do not revert. Users do not pay fees for failed transactions.
  • Configurable: You can customize your privacy, speed, and refund settings.

We want to thank MiningDAO, mistX, and Nethermind for significant code contributions, testing, and being early adopters of Flashbots Protect.
