Special Mechanisms Group

What Special Mechanisms Group does

Special Mechanisms Group (SMG) is a blockchain research and development organization focused on mechanism design for proof-of-stake blockchains, particularly Ethereum. Founded in 2021 and acquired by Consensys in 2024, SMG produces a published research series (SPEC-01 through SPEC-06) covering censorship resistance in on-chain auctions, the centralizing effects of private order flow on proposer-builder separation, structural advantages for integrated builders in MEV-Boost, dynamic transaction fee mechanisms, intent-based markets, and optimization of proof-of-stake exit queues. The team includes researchers with academic credentials at the intersection of theoretical economics, computer science, and game theory. The organization's technical output combines arXiv-style academic papers with detailed public threads explaining research findings to protocol engineers and the broader Ethereum community.

In January 2026, SMG acquired MEV Blocker RPC from CoW DAO, transitioning from a pure-research entity into an operator of production MEV protection infrastructure. MEV Blocker is a remote procedure call (RPC) service that shields users from frontrunning and sandwich attacks by routing transactions through backrunning auction infrastructure, with MEV value returned to users as rebates. Since inception, the service has served more than 4.5 million unique users and delivered 6,177 ETH in rebates. SMG is integrated within the Consensys ecosystem alongside MetaMask, Linea, and Infura, which provides distribution scale but does not appear to generate direct external revenue.

SMG operates as a research division rather than a commercial product business. MEV Blocker is distributed as freely accessible infrastructure with no pricing disclosed, and value flows back to users rather than to SMG. The go-to-market model is product-led growth combined with community-led academic publishing — research and infrastructure are made openly available to influence protocol design discourse and onboard users through wallet-level configuration. Customer segments are horizontal: Web3/Ethereum users and blockchain protocol teams. Revenue is not publicly disclosed, and there are no enterprise contracts, API offerings, or pricing models in the public record.

Revenue model

1. Research and Development Services: SMG operates as a research division within Consensys, providing mechanism design expertise and MEV-related solutions. Revenue generation is not explicitly disclosed.
2. MEV Blocker RPC Infrastructure: MEV Blocker returns MEV value to users through rebates (6,177 ETH delivered to users), rather than generating direct revenue. The infrastructure is designed to align MEV extraction with user interests.

Core offering

Special Mechanisms Group (SMG) is a blockchain research and development organization that builds and operates MEV Blocker RPC, a public infrastructure endpoint that protects Ethereum users from maximal extractable value (MEV) attacks through backrunning auctions that return rebates to users. SMG also publishes applied research on blockchain protocol economics, transaction fee markets, and mechanism design via its SPEC paper series.

Product overview

Special Mechanisms Group (SMG) is a blockchain research and development organization focused on mechanism design and MEV (Maximal Extractable Value) research. The primary commercial product is the MEV Blocker RPC, acquired from CoW DAO, which provides user-aligned MEV protection through backrunning auctions. SMG also produces a body of theoretical research publications (SPEC-01 through SPEC-06) covering topics including censorship resistance, proposer-builder separation, dynamic transaction fee mechanisms, intent-based markets, and proof-of-stake exit queue optimization.

Differentiator

Problem solved

Functional benefit

Brands

• MEV Blocker RPC: MEV protection RPC providing backrunning auctions and user-aligned transaction execution, acquired by SMG in January 2026.

Products and services

• MEV Blocker RPC A free, public remote procedure call (RPC) endpoint for Ethereum and EVM-compatible chains that protects end users from maximal extractable value (MEV) attacks such as sandwich attacks and frontrunning. Users configure MEV Blocker as a custom RPC in self-custodial wallets or browser extensions, and MEV value captured by block builders is rebated back to the user via a backrunning auction.

Partnerships

Three partnerships are on record, tiered core and flagship.

• CoW DAOcoreStrategic or Co-development Partner · 23 January 2026CoW DAO, co-creator of MEV Blocker, will support the transition of MEV Blocker into the Consensys/SMG ecosystem. The DAO pioneered MEV protection through CoW Protocol and CoW Swap. CoW DAO created the first MEV-protected DEX, RPC, and AMM, and will continue providing MEV protection through its core products while supporting SMG's stewardship of MEV Blocker.
• ConsensysflagshipOthersSMG is a division of Consensys, the blockchain software company behind MetaMask, Linea, and Infura. Consensys acquired SMG to deliver state-of-the-art MEV solutions. SMG operates as the mechanism design powerhouse within Consensys, contributing to the broader ecosystem of Ethereum infrastructure.
• MEV Blocker RPC (Acquisition)coreOthersSMG acquired MEV Blocker RPC to strengthen its MEV expertise and accelerate its mission to deliver accessible, user-centric Web3. MEV Blocker is one of the most widely adopted MEV protection RPCs, bringing advanced backrunning auctions, 4.5M+ users, and 6,177 ETH in delivered rebates to SMG's portfolio.

Others

• Polygon Labs: Polygon Labs operates proof-of-stake blockchain infrastructure and publishes research on scaling and protocol design. Comparable as a research-driven blockchain infrastructure organization, though focused on scaling rather than MEV mechanism design.
• Paradigm Research: Paradigm publishes foundational MEV research (the original Flash Boys 2.0 paper) and invests in the ecosystem. Comparable to SMG as a research-driven entity shaping Ethereum's MEV and protocol direction, though structured as a venture fund rather than an operating company.
• a16z crypto research: a16z crypto publishes original research on MEV, protocol economics, and blockchain mechanism design, making it a comparable research-output peer to SMG, though embedded within a venture fund rather than an operating company.
• Optimism Foundation: Optimism Foundation conducts public research on rollup economics, sequencing, and MEV on Layer 2. Adjacent peer in that it operates as a research-and-protocol organization within the Ethereum ecosystem with relevance to SMG's MEV and fee-mechanism research.

Emerging players

• Eden Network: Eden Network is a transaction-ordering and block-builder network with MEV-related staking economics. It overlaps with SMG's research on auction design, private order flow, and builder centralization, though focused more on validator-side products than user protection.
• Manifold Finance: Manifold Finance operates MEV infrastructure including block-building and MEV protection tools (e.g., MEV Blocker competitors), making it a relevant emerging peer in the MEV protection and backrunning auction space that SMG now occupies.
• Chainlink Labs: Chainlink operates core blockchain infrastructure (oracles, CCIP) and has expanded into broader Web3 infrastructure. Comparable to SMG as a research-and-infrastructure organization adjacent to Consensys's stack, though focused on oracle and cross-chain rather than MEV.

Direct peers

• bloXroute Labs: bloXroute provides blockchain infrastructure including MEV-related services and low-latency block propagation, directly competing with elements of the MEV-Boost stack that SMG analyzes and MEV Blocker attempts to protect against.
• CoW DAO: CoW DAO co-created MEV Blocker RPC and operates CoW Protocol and CoW Swap, pioneering MEV-protected DEX and AMM design. It is both a strategic partner (transitioning MEV Blocker to SMG) and the closest product-side comparable to SMG's MEV protection work.
• Flashbots: Flashbots is the original MEV research and infrastructure organization, operating MEV-Boost, MEV-Geth, and Protect (a competing MEV-protection RPC). It is the closest direct competitor to SMG in MEV research, RPC protection, and Ethereum protocol-level analysis.
