The Future of MEV: From Extraction to Protocol-Level Mitigation

Retail user transactions are blindly routed to public mempools, creating a $1B+ annual market for predatory front-running and sandwich attacks.

• Value Leakage: Users lose ~0.5-1% per swap to MEV.
• Network Congestion: Failed attack transactions spam the chain.
• Centralization Pressure: Searchers and builders consolidate to capture value.

Encrypted transaction pools hide intent from searchers until execution, while SUAVE (Shared Unbiased Auction for Value Expression) creates a decentralized, neutral auction house for order flow.

• Privacy: Threshold Encryption (e.g., Shutter Network) blinds transaction content.
• Fair Markets: SUAVE's chain-agnostic auction ensures MEV revenue flows back to users.
• Decentralization: Breaks the builder/relay oligopoly by standardizing block building.

Bridging assets creates fragmented liquidity and exposes users to cross-chain MEV, where arbitrageurs exploit price differences across venues like Uniswap and Curve.

• Latency Arbitrage: Searchers profit from slow message passing between chains.
• Oracle Manipulation: Attacks on price feeds used by bridges.
• Widened Slippage: Users pay more due to fragmented pools.

Users specify what they want, not how to do it. Solvers (e.g., UniswapX, CowSwap) compete to fulfill the intent optimally. Shared Sequencers (like Espresso, Astria) provide atomic cross-rollup execution.

• Better Prices: Solvers find optimal routes across DEXs, CEXs, and bridges.
• MEV Capture Reversal: Auction mechanics return value to the user.
• Atomic Composability: Enables complex, cross-domain transactions without interim risk.

PBS (Proposer-Builder Separation) created a builder market where a few entities (e.g., Flashbots, BloXroute) control block production, creating censorship risks and centralizing MEV profits.

• Censorship: Builders can exclude OFAC-sanctioned transactions.
• Central Points of Failure: ~80% of Ethereum blocks are built by 3-5 entities.
• Economic Capture: Value accrues to infrastructure, not validators or users.

Protocol-level PBS (ePBS) bakes block building into the consensus layer. MEV-Burn (like EIP-1559 for blockspace) destroys excess MEV revenue, while MEV-Smoothing distributes it evenly to all validators.

• Anti-Censorship: Decentralized, credibly neutral block production.
• Reduced Centralization: Removes economic incentive for builder oligopolies.
• Protocol Revenue: MEV becomes a sustainable, public good funding mechanism.

MEV creates a positive feedback loop where the largest validators or builders capture the most value, leading to stake consolidation. This directly attacks the core security assumption of decentralized consensus.

• Stake Pooling: Rational stakers flock to the most profitable pools, creating >33% cartels.
• Hardware Arms Race: Specialized MEV-boost relays and builders create insurmountable economies of scale for newcomers.

MEV mitigation often sacrifices liveness for fairness. Protocols like CowSwap and UniswapX use batch auctions and solver networks, which introduce latency and complexity that can break during high volatility.

• Failure Modes: Solver downtime or censorship can halt settlement, creating systemic counterparty risk.
• Oracle Dependence: Many intent-based systems rely on external price feeds, adding another attack vector.

MEV presents a clear, quantifiable 'harm' narrative for regulators. The SEC could classify front-running as market manipulation, forcing compliance onto base layers and killing permissionless innovation.

• KYC for Validators: Regulators could mandate identity for block proposers, destroying censorship resistance.
• Protocol Liability: Flashbots SUAVE or similar 'neutral' infrastructure could be deemed a regulated exchange.

Each mitigation—encrypted mempools, threshold encryption, commit-reveal schemes—adds overhead, latency, and new bugs. The system becomes a fragile Rube Goldberg machine vulnerable to novel attacks.

• Attack Surface: Every new component (e.g., Shutter Network keypers) is a new target.
• User Experience: Finality times balloon, breaking expectations for DeFi and gaming applications.

Protocols like EigenLayer and Across attempt to internalize MEV for stakers or users. This creates perverse incentives where security subsidies depend on volatile, extractive revenue streams, not sustainable fees.

• Ponzi Dynamics: Staking yields become reliant on capturing the next user's MEV.
• Value Leakage: Sophisticated searchers will always find edges, ensuring value leaks to the edges of the system.

Cross-chain MEV via bridges like LayerZero or Wormhole is a nightmare. Arbitrage between chains is necessary for efficiency, but creates atomicity risks where a failed transaction on one chain can destabilize another.

• Cross-Chain Contagion: A liquidity crisis on Chain A, triggered by MEV, can propagate to Chain B.
• Unified Mempool Risk: Shared sequencing layers become single points of failure for the entire multi-chain ecosystem.

Public mempools and priority gas auctions are a ~$1B+ annual tax on users, creating systemic risks like chain reorgs. The solution is protocol-level mitigation that internalizes MEV into the consensus mechanism itself.

• Key Benefit 1: Fairer ordering via PBS (Proposer-Builder Separation) or encrypted mempools like Shutter Network.
• Key Benefit 2: Reduced chain instability by removing incentives for time-bandit attacks.

Solving for user intent ("I want this outcome") instead of transactions ("execute this calldata") abstracts away MEV complexity. This shifts competition from searchers to solvers.

• Key Benefit 1: Better UX & yield via systems like UniswapX, CowSwap, and Across.
• Key Benefit 2: Native cross-chain composability as seen in layerzero's omnichain intents, reducing bridge MEV risks.

Specialized builders like Flashbots SUAVE, Titan, and bloxroute are becoming critical infrastructure with >60% of Ethereum blocks. This creates centralization risks but also investable middleware.

• Key Benefit 1: Reliable block space for applications needing censorship resistance or fast inclusion.
• Key Benefit 2: New revenue streams from selling orderflow or operating builder nodes.

Encrypted mempools (e.g., Shutter, EigenLayer's MEVM) and TEEs are emerging to neutralize frontrunning. This isn't just about privacy—it's about creating a fair, efficient market for block space.

• Key Benefit 1: Eliminates toxic MEV like frontrunning, protecting DeFi yields.
• Key Benefit 2: Enables new applications requiring confidential on-chain state, a multi-billion dollar design space.

Solana's Jito, Cosmos's Skip Protocol, and Avalanche's subnet economies prove MEV is not an Ethereum-specific problem. Each ecosystem requires tailored solutions.

• Key Benefit 1: First-mover advantage for builders who understand nascent MEV markets on new chains.
• Key Benefit 2: Cross-chain arbitrage as a dominant MEV category, demanding new relay infrastructure.

MEV practices like frontrunning resemble traditional market abuse. Protocols that bake in fair ordering (e.g., CowSwap's batch auctions) are better positioned for compliance.

• Key Benefit 1: Regulatory moat for protocols with transparent, fair settlement layers.
• Key Benefit 2: Institutional adoption hinges on eliminating opaque extractive middlemen from the transaction stack.
