MEV is not a bug; it is a fundamental property of permissionless, asynchronous systems. The arbitrage and liquidation opportunities created by block ordering are a permanent feature, not an anomaly.

Why MEV Will Become a Core Protocol Feature
MEV is no longer a bug to be patched. This analysis argues that protocols like Ethereum are internalizing MEV via PBS, transforming it from a parasitic tax into a fundamental primitive that funds security and dictates future chain architecture.
introduction
THE INEVITABLE SHIFT
Introduction: The Hidden Tax Becomes the Foundation
MEV is transitioning from a parasitic extractive force to a core, protocol-owned revenue stream and coordination mechanism.
The extractive era is ending. Protocols like Flashbots' SUAVE and Cosmos' Skip Protocol are formalizing MEV capture, shifting value from opaque searchers back to validators and users.
Protocols will monetize their own flow. Future L1s and L2s like Arbitrum and Solana will bake MEV redistribution into their consensus and fee markets, turning a hidden tax into a sustainable treasury asset.
Evidence: Ethereum's PBS (proposer-builder separation) and MEV-Boost already route ~90% of block rewards through a structured auction, proving the model's viability for protocol-level capture.

Key Trends: The Three Pillars of MEV Internalization
MEV is no longer a bug; it's a fundamental protocol resource. The next wave of L1/L2 design will systematically capture and redistribute this value.
01
The Problem: Proposer-Builder Separation (PBS) is Incomplete
Ethereum's PBS outsources block building to a centralized cartel of builders, creating systemic risk and leaking value. The solution is In-Protocol PBS, where the protocol itself is the canonical builder.
- Key Benefit: Eliminates builder centralization and censorship vectors.
- Key Benefit: Captures ~90%+ of MEV revenue for direct protocol/validator redistribution.

The Solution: Native Order Flow Auctions (OFA)
Letting users broadcast raw transactions to the public mempool is financial suicide. Protocols like SUAVE, Flashbots Protect, and CowSwap demonstrate the future: transactions are routed through a trust-minimized auction before hitting the chain.
- Key Benefit: Users get best execution and a share of the surplus.
- Key Benefit: Democratizes MEV access, breaking searcher oligopolies.

The Architecture: Encrypted Mempools & Pre-Confirmations
Frontrunning requires visibility. A threshold-encrypted mempool (e.g., Shutter Network) with pre-confirmations (e.g., Espresso, EigenLayer) solves this. Transactions are encrypted until inclusion, and users get fast, soft commitments.
- Key Benefit: Eliminates harmful MEV (frontrunning, sandwiching) at the network layer.
- Key Benefit: Enables sub-second finality for UX-critical dApps like perps and gaming.

THE INEVITABLE ABSORPTION
Deep Dive: From Parasite to Primitive
MEV is transitioning from a network exploit to a formalized, protocol-level revenue stream and coordination mechanism.
MEV is a protocol tax. It is not an external attack but a structural feature of permissionless sequencing. Protocols that ignore it cede value and control to third-party searchers and builders.
The future is explicit MEV. Protocols like SUAVE and Flashbots are building infrastructure to internalize this value. This transforms MEV from a dark forest into a transparent, programmable resource.
App-chains will monetize ordering. Sovereign rollups and app-specific chains, like those built with Dymension or Celestia, will implement native orderflow auctions. This captures revenue that currently leaks to Ethereum block builders.
Evidence: Ethereum's PBS (Proposer-Builder Separation) formalized MEV extraction. Post-merge, over 90% of blocks are built by professional builders, proving MEV is already a core protocol component.

MEV Revenue: From Opaque to On-Chain
Comparison of MEV revenue capture and distribution models, from traditional extraction to integrated protocol design.
| Feature / Metric | Traditional Dark Forest (e.g., Ethereum pre-PBS) | Auction-Based PBS (e.g., Flashbots SUAVE, Ethereum PBS) | Protocol-Integrated MEV (e.g., Osmosis, CowSwap, UniswapX) |
|---|---|---|---|
Revenue Visibility | Opaque (off-chain) | Partially Opaque (bid visibility only) | Fully On-Chain |
Revenue Recipient | Searchers & Validators | Validators & Proposers (via bids) | Protocol Treasury & Users (via rebates) |
User Protection | Partial (censorship resistance via crLists) | ||
Extraction Efficiency | High (unconstrained) | High (constrained by auction) | Optimized for Fair Outcomes |
Avg. Searcher Profit Margin | 15-25% | 5-15% (auction competition) | 0-5% (or negative via MEV burn) |
Integration Complexity | None (exogenous) | Consensus Layer (e.g., Ethereum) | Application Layer (AMM logic, solver competition) |
Key Enabling Tech | Private Mempools | Builder-Blocker Separation, SUAVE | Batch Auctions, Intents, Threshold Encryption |
Example of Redistribution | None | Proposer Payment (MEV-Boost) | LP Rebates (Osmosis), Fee Discounts (CowSwap) |
counter-argument
THE TRADEOFF
Counter-Argument: Centralization is the Inevitable Cost
The operational complexity of MEV management will drive consolidation into a few specialized, protocol-integrated providers.
MEV infrastructure is a natural monopoly. The capital, data, and latency advantages required for profitable MEV extraction create immense economies of scale, mirroring the centralization of cloud providers like AWS. Protocols will not compete with this reality; they will formalize it.
Protocols will integrate MEV as a service. Just as Flashbots' SUAVE aims to be a shared sequencer, future L1/L2s will outsource block building to a handful of licensed, auditable builders like Jito Labs or bloXroute. This trades ideological decentralization for predictable, auctioned revenue.
The cost is explicit centralization. The benefit is economic security and user experience. A formalized MEV market provides a stable, protocol-owned revenue stream and allows for features like pre-confirmation guarantees, which are impossible in a fully permissionless builder set.
Evidence: Ethereum's PBS roadmap and the dominance of builder-of-builders like Manifold demonstrate this trajectory. Over 90% of Ethereum blocks are now built by a few entities, a trend protocols will codify rather than fight.

Protocol Spotlight: Architecting the MEV-Aware Future
MEV is no longer a bug; it's a fundamental network force. The next generation of protocols will bake MEV management into their core architecture.
01
The Problem: Unchecked MEV is a Tax on Users
Public mempools are a free-for-all. Searchers and validators compete to extract value, leading to predictable costs for end-users.\n- Front-running and sandwich attacks cost DeFi users ~$1B+ annually.\n- Latency wars centralize block production, creating systemic risk.\n- Unpredictable slippage and failed transactions degrade UX.

The Solution: Private Order Flow & Intents
Protocols like UniswapX, CowSwap, and 1inch Fusion shift the paradigm from transactions to intents. Users specify what they want, not how to do it.\n- MEV becomes a rebate, not a cost, via order flow auctions (OFAs).\n- Permissionless solvers compete to fulfill intents, driving efficiency.\n- Privacy via encrypted mempools (e.g., Shutter Network) prevents front-running.

The Bridge: Cross-Chain MEV as a Service
Bridges like Across and messaging layers like LayerZero are the new MEV frontier. Cross-chain arbitrage is a $100M+ opportunity, but naive bridges are vulnerable.\n- Optimistic verification (Across) enables fast, secure bridging by leveraging economic security.\n- Unified liquidity pools reduce fragmentation and arbitrage surface.\n- Secure off-chain actors (e.g., Succinct Labs' Telepathy) enable generalized cross-chain intent fulfillment.

The Endgame: MEV as Protocol Revenue
The final evolution is MEV becoming a primary, sustainable revenue source for the protocol itself, not just validators. This is the Superfluid Staking thesis.\n- Shared sequencers on L2s (e.g., Espresso Systems, Astria) capture and redistribute MEV.\n- Protocol-controlled solvers turn MEV into a public good, funding development and security.\n- Tokenomics 2.0: Stakers earn yield from both fees and captured MEV.

The Risk: Centralization & Regulatory Capture
Efficient MEV capture is a centralizing force. The entities controlling order flow or block building become critical choke points.\n- OFA winners (e.g., Flashbots SUAVE) could become de facto centralized exchanges.\n- Regulators may target MEV as unregistered broker-dealer activity.\n- Solution: Enshrine credibly neutral, open-source PBS and solver networks in protocol code.

Takeaways: The New MEV Reality
MEV is no longer a bug; it's the fundamental economic force that will be formalized and productized by the next generation of protocols.
01
The Problem: Opaque, Adversarial Extraction
Traditional MEV is a zero-sum game where searchers, builders, and validators compete in the dark. This creates systemic risks like chain reorgs, front-running, and a ~$1B+ annual tax on users. The value is captured off-protocol, offering no direct benefit to the network or its participants.

The Solution: PBS & SUAVE
Protocols are baking MEV management in. Proposer-Builder Separation (PBS) formalizes the block building market. EigenLayer, Flashbots SUAVE, and native PBS designs (e.g., Ethereum's roadmap) turn MEV into an on-chain, auctioned resource. This creates a transparent, efficient market where value accrues to validators/stakers.
