The Future of MEV: From Extraction to Social Utility Metrics

Traditional MEV is a tax on users, creating systemic risks like sandwich attacks and chain reorgs. It's a zero-sum game where searchers profit at the expense of retail.

• Cost: Extracts ~$1B+ annually from DeFi users.
• Risk: Increases network latency and centralization pressure.
• Outcome: Misaligns incentives between builders and the protocol's long-term health.

Flip the model by letting users declare what they want, not how to do it. Solvers compete to fulfill the intent optimally, capturing MEV as a service fee, not a theft.

• Efficiency: Solvers aggregate liquidity across Uniswap, 1inch, Balancer.
• User Benefit: Guaranteed execution, no front-running, often better prices.
• Utility Metric: MEV revenue is tied to user surplus improvement, creating a positive feedback loop.

Protocols like Ethereum with Proposer-Builder Separation (PBS) can redirect a portion of MEV revenue to fund public goods (e.g., via EigenLayer restaking or direct treasury).

• Alignment: Redirects billions in potential revenue to protocol development and staker rewards.
• Transparency: MEV auctions (e.g., Flashbots SUAVE) make extraction quantifiable and redistributable.
• Utility Metric: % of MEV revenue redistributed becomes a key health indicator for L1/L2s.

Projects like Across and LayerZero turn cross-chain arbitrage into a reliable liquidity service. This transforms a chaotic race into a verifiable, efficient settlement process.

• Utility: Enables atomic composability across chains, a foundational primitive for DeFi 2.0.
• Metric: Settlement latency and guaranteed execution replace pure profit as the key performance indicator.
• Outcome: MEV becomes the economic engine for secure interoperability.

The core KPI for Social Utility MEV. It measures the economic value created for the user versus value taken from the user.

• Calculation: (Best Execution Price - Actual Price) * Size.
• Benchmark: Protocols like CowSwap already publish this data.
• Impact: Forces infrastructure (searchers, builders, solvers) to compete on user outcomes, not just their own profit.

Without privacy, social utility MEV is impossible. Technologies like threshold encryption (e.g., Shutter Network) and FHE hide transaction details until execution, neutralizing predatory front-running.

• Function: Enables fair auctions for intent fulfillment.
• Requirement: A prerequisite for the ethical SUAVE vision or Cosmos-based MEV mitigation.
• Utility Metric: % of transactions encrypted directly correlates to a healthier, more equitable MEV landscape.

Unchecked MEV extraction acts as a tax on users, creating systemic risks like chain reorgs and front-running. The value is captured by a few searchers and validators, with ~$1B+ extracted annually, offering no network benefit.

• Negative Externalities: Degrades user experience and trust.
• Centralizing Force: Concentrates power with the most sophisticated actors.
• Wasted Cycles: Network resources spent on zero-sum games.

A decentralized block-building marketplace that separates block proposal from construction. It turns MEV into a competitive, transparent commodity.

• Credible Neutrality: Execution and intents are processed in a secure, shared environment.
• Cross-Chain Future: Aims to be the MEV-coordination layer for all chains.
• Proposer-Builder Separation (PBS): Enforced at the protocol level to prevent centralization.

These intent-based protocols internalize MEV, turning it from a cost into a user benefit via batch auctions and solver competition.

• Surplus Capture: Solvers compete to give users the best price, with MEV recycled as savings.
• No Failed Txs: Users sign intents, not transactions, eliminating gas waste.
• Privacy: Hides intent from general mempool, preventing front-running.

Protocols like Flashbots MEV-Share and Astria are creating frameworks to redistribute MEV revenue. Validators and builders earn based on social utility metrics, not just profit.

• Programmable Redistribution: A portion of MEV can be directed to public goods funding or user rebates.
• Reputation-Based Access: Builders with better latency and inclusion rates get priority, rewarding reliability.
• Transparent Order Flow: Users can opt-in to share MEV for a guaranteed kickback.

These protocols tokenize the right to earn MEV, creating liquid markets for staking yield. This turns a validator's hidden advantage into a tradable, composable asset.

• Liquid Staking Tokens (LSTs): Jito's JTO and EigenLayer's restaking bundle MEV revenue into yield.
• Economic Security: MEV revenue strengthens the slashing economics of restaked assets.
• Democratized Access: Retail can gain exposure to sophisticated MEV strategies via LSTs.

The endgame is a standardized metric to quantify a block builder's social contribution, moving beyond maximal extractable value to maximal usable value.

• Components: User savings, public goods funding, network stability, and liveness.
• Protocol Incentives: Block rewards could be weighted by a builder's MUQ score.
• VC Thesis: The most valuable infra will be that which maximizes and measures MUQ.

Global regulators may fail to distinguish between predatory front-running and beneficial PBS, treating all MEV as illegal market manipulation. This could kill the nascent utility ecosystem before it matures.

• Risk: A blanket ban on searcher-builder separation or order flow auctions.
• Impact: Forces MEV back into the shadows, eliminating transparency and fair revenue distribution.
• Precedent: The SEC's stance on crypto staking as a security.

Builder dominance by entities like Flashbots (via SUAVE) or L2 sequencers creates a new, centralized point of failure. A builder cartel could censor transactions or capture all utility value.

• Risk: Replaces decentralized validator extractable value with centralized builder extractable value.
• Metric: A single builder controlling >33% of blocks negates PBS benefits.
• Example: The OFAC-compliant blocks phenomenon post-Merge.

The definition of 'social utility' becomes a political battleground. Well-funded DAOs or protocols could game metrics (e.g., votes for grant distribution) to divert funds, turning MEV redistribution into a new form of rent-seeking.

• Risk: Optimism's RetroPGF and Ethereum's PBS auctions become corrupted influence markets.
• Outcome: Zero-sum political games destroy trust, causing users and builders to opt-out.
• Consequence: Utility MEV reverts to being simple, transparent extraction.

The stack for managing MEV utility—PBS, OFAs, SUAVE, cross-chain intents—becomes too complex for developers to build on or for users to trust. Failure modes become unpredictable and uninsurable.

• Risk: Systemic fragility scares away institutional adoption and mainstream DeFi.
• Symptom: Proliferation of intent-based standards (UniswapX, CowSwap) with no clear winner.
• Result: The market chooses 'good enough' centralized sequencers (e.g., Arbitrum, Solana) over fragile utility layers.

The value captured for public goods is insufficient to fund the infrastructure. Searchers and builders operating at a loss revert to dark pools and private order flow to survive.

• Risk: Projects like Flashbots Protect or CowSwap fail to achieve sustainable fee models.
• Metric: If <5% of total MEV is redirected, the utility layer is economically irrelevant.
• Domino Effect: Protocols abandon on-chain settlement for off-chain efficiency, killing the utility thesis at its root.

Maximizing MEV utility (e.g., efficient batch auctions) requires revealing transaction intent. This conflicts with growing demand for privacy via protocols like Aztec or Nocturne.

• Risk: Privacy-conscious users fork away from utility-optimized chains, fragmenting liquidity.
• Dilemma: You cannot have a fully private, fully efficient market. One must be sacrificed.
• Outcome: The market bifurcates, preventing a unified standard for MEV utility from emerging.
