# Flashbots – MEV Infrastructure & SUAVE

**Category:** MEV Infrastructure / Privacy Infrastructure
**Maturity:** Production (Flashbots Auction), Development (SUAVE)
**Maturity:** Production (MEV-Boost, BuilderNet, Rollup-Boost, Protect RPC, MEV-Share)
**Focus:** MEV mitigation, private mempools, and decentralized block building

## Overview

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 is a research and development organization formed to mitigate the negative externalities posed by Maximal Extractable Value (MEV) to stateful blockchains, starting with Ethereum. Our primary focus is to enable a permissionless, transparent, and sustainable ecosystem for MEV, via a three-pronged approach:
- **Illuminate**: bringing transparency to MEV activity, quantifying its impact, and reducing information asymmetry between participants.
- **Democratize**: democratizing access to MEV via open platforms that maximize competition and are freely available to all.
- **Distribute**: enabling sustainable distribution of any remaining MEV.

## Key Use Cases / Patterns
Our efforts are separated into three sub-organizations:

- [Pre-trade Privacy](../patterns/pattern-pretrade-privacy-shutter-suave.md) - Private intent expression via SUAVE
- [Private Broadcasting](../approaches/approach-private-broadcasting.md) - MEV protection through private mempools
**Product:** builds core infrastructure and ecosystem tooling that redefines the block production supply chain. This includes MEV-Boost, BuilderNet, Rollup-Boost, Protect RPC, and MEV-Share.
**Research:** an open, transparent, and collaborative research effort that explores MEV market dynamics and blockchain design challenges at the intersection of economics, security, and cryptography. To fuel the collaborative nature of our research, anybody can submit a Flashbots Research Proposal (FRPs) and might become eligible for a grant.
**Coordination**: an organizational effort to streamline operational processes, interface with external teams in the ecosystem and scale ourselves to maximize our impact.

## Technical Approach
Flashbots Research and Product are tightly-coupled dual engines that propel our organization forward in a phased approach:

**Flashbots Auction:**
- Long-term oriented research efforts spec out and update our roadmap, define our organization’s phases and identify key milestones.
- Milestone-oriented engineering efforts ship core infrastructure and ecosystem tools while collecting data and other artifacts that feed back into research.
Our work is open source and you can follow our progress in each respective repository of the Flashbots organization. Anyone is welcome to comment on an issue or pick it up entirely.

- **Private Mempools:** Transactions submitted directly to builders, bypassing public mempool
- **MEV-Share:** Users capture portion of MEV from their transactions
- **Block Building:** Competitive block construction with MEV extraction
The best way to interact with the Flashbots community is through our [forum](https://collective.flashbots.net/), which is our central communication platform for conversations, announcements and information sharing. We also publish weekly [MEV Letters](https://collective.flashbots.net/tag/the-mev-letter) that aggregate information and provide summaries on everything Flashbots and MEV.

**SUAVE (Under Development):**
## Flashbots Products

- **Universal Intent Pool:** Cross-domain intent expression and matching
- **Programmable Privacy:** Selective revelation of intent information
- **Decentralized Execution:** Multiple execution environments for intent fulfillment

## What It Provides

- Private transaction submission bypassing public mempool
- MEV protection through direct builder relationships
- Revenue sharing mechanisms (MEV-Share)
- Cross-chain intent expression (SUAVE)
- Decentralized block building infrastructure

## What It Doesn't Cover

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

## Integration Notes

- **Networks:** Ethereum mainnet (Flashbots), Multi-chain (SUAVE)
- **Developer Tools:** MEV-Share SDK, Flashbots Auction APIs
- **Builder Network:** Requires integration with participating builders
- **Intent Standards:** SUAVE developing cross-chain intent standards

## Strengths

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

## Limitations

- Centralization concerns with builder relationships
- SUAVE still in development phase
- Limited privacy guarantees (trust-based model)
- Regulatory uncertainty around MEV redistribution
- **MEV-Boost**:
- [**MEV-Boost Sidecar**](https://github.com/flashbots/mev-boost): Enabling Ethereum validators to access a competitive block-building market through out-of-protocol PBS.
- [**MEV-Boost relay**](https://github.com/flashbots/mev-boost-relay): The trusted mediator between producers and builders enabling [PBS](https://ethresear.ch/t/proposer-block-builder-separation-friendly-fee-market-designs/9725).
- [**BuilderNet**](https://buildernet.org/): Block building network for Ethereum that runs on TEEs and shares MEV with the community.
- **[rbuilder](https://github.com/flashbots/rbuilder)**: Blazingly fast, cutting edge block builder written in Rust.
- **[Rollup-Boost](https://github.com/flashbots/rollup-boost)**: Verifiable block-building platform for rollups with modular components for upgrading rollups across performance, programmability, and decentralization.
- **[op-rbuilder](https://github.com/flashbots/op-rbuilder/)**: High-performance Rust-based block builder for the OP Stack.
- **[Protect RPC](https://protect.flashbots.net/)**: A secure way to transact on Ethereum, protecting transactions from frontrunning and giving users refunds on gas fees and MEV.
- **[MEV-Share](https://github.com/flashbots/mev-share-node)**: Protocol for users, wallets, and applications to internalize the MEV that their transactions create
