Flashbots

Flashbots develops MEV infrastructure including private mempools, block building, and SUAVE (Single Unifying Auction for Value Expression), a decentralized platform for private intent expression and execution. Flashbots Auction is in production on Ethereum mainnet; SUAVE is under development.

Flashbots – MEV Infrastructure & SUAVE

Fits with patterns

Not a substitute for

  • Complete MEV elimination (redistributes rather than eliminates)
  • Privacy after execution (transactions remain visible on-chain)
  • Regulatory compliance frameworks
  • Long-term privacy guarantees (relies on builder trust)

Architecture

Flashbots Auction: transactions are submitted directly to builders, bypassing the public mempool; MEV-Share lets users capture a portion of the MEV from their transactions; competitive block construction handles MEV extraction.

SUAVE (under development): a universal intent pool for cross-domain intent expression and matching, programmable privacy (selective revelation of intent information), and decentralized execution across multiple environments.

Enterprise demand and use cases

  • Private transaction submission bypassing the public mempool
  • MEV protection through direct builder relationships
  • Revenue sharing via MEV-Share
  • Cross-chain intent expression (SUAVE)

Technical details

  • Networks: Ethereum mainnet (Flashbots Auction); multi-chain (SUAVE)
  • Developer tools: MEV-Share SDK, Flashbots Auction APIs
  • Builder network: requires integration with participating builders
  • Intent standards: SUAVE is developing cross-chain intent standards

Strengths

  • Established MEV mitigation with significant adoption
  • Strong relationship with the Ethereum ecosystem
  • Active development of next-generation infrastructure (SUAVE)
  • Revenue-sharing mechanisms align user incentives

Risks and open questions

  • Centralization concerns around builder relationships
  • SUAVE still in development
  • Limited privacy guarantees (trust-based model)
  • Regulatory uncertainty around MEV redistribution
