MEV protection is a subsidy. Protocols like CowSwap and UniswapX use solvers and fillers who are themselves sophisticated MEV searchers. User protection payments flow directly to these actors, funding their operational scale.

Why 'MEV-Aware' Protocols Are Just Feeding the Beast
Intent-based designs like CowSwap and UniswapX promise user protection by internalizing MEV. This analysis argues they instead optimize the extraction pipeline, legitimize searchers, and expand the total MEV economy, creating a larger, more systemic problem.
introduction
THE CORE CONTRADICTION
Introduction: The Faustian Bargain of User Protection
Protocols attempting to shield users from MEV are inadvertently subsidizing and strengthening the very extractive infrastructure they seek to bypass.
You centralize the beast. Outsourcing order flow to a few designated solvers (e.g., CoW DAO solvers) or intent-based networks creates new, powerful intermediaries. This consolidates, not eliminates, extractive power.
The infrastructure learns. Every protected transaction provides a data feed on user intent and willingness-to-pay. This data trains the very generalized frontrunning bots the system aims to defeat.
Evidence: Over 90% of CoW Swap's surplus is captured by its solver network. This 'protection' fee is the new MEV, just with a different label and a more centralized extraction point.

WHY 'MEV-AWARE' PROTOCOLS ARE JUST FEEDING THE BEAST
The MEV Industrial Complex: Three Accelerating Trends
Protocols that attempt to 'manage' MEV often inadvertently centralize and subsidize the very extractors they aim to constrain.
01
The Problem: The 'Fair Ordering' Mirage
Protocols like SUAVE or Flashbots Protect promise fair ordering by outsourcing it to a separate network. This doesn't eliminate MEV; it centralizes the auction into a single, privileged sequencer or builder. The result is a new, protocol-sanctioned cartel that captures rent, creating a single point of failure and censorship.
- Centralizes economic and technical power
- Creates a new rent-seeking layer
- Fails the credible neutrality test

The Problem: Subsidized Arbitrage via 'MEV-Rebates'
DEXs like CowSwap and intent-based bridges like Across use solvers who internalize MEV for better prices. They pay solvers via orderflow subsidies (e.g., gasToken). This turns the protocol's treasury into a permanent subsidy for sophisticated searchers, baking MEV extraction costs into the system's economics. It's a wealth transfer from LPs/tokenholders to bots.
- Converts protocol treasury into MEV payment rail
- Obfuscates true cost of execution
- Creates unsustainable economic model

The Problem: The Proposer-Builder Separation (PBS) Trap
Ethereum's PBS formalizes the builder role, creating a professionalized MEV extraction class. 'MEV-aware' L2s that adopt PBS variants (like Arbitrum's timeboost) are not avoiding the problem; they are importing Ethereum's extractive infrastructure. This entrenches builder dominance, making the network's liveness dependent on their profitability.
- Institutionalizes extractive middlemen
- Links chain security to MEV profits
- L2s inherit L1's structural flaws

THE STRATEGIC SHIFT
From Leakage to Pipeline: How Internalization Grows the Pie
Protocols that attempt to be 'MEV-aware' without controlling execution are merely subsidizing extractors, while internalizing the flow creates sustainable value capture.
MEV-aware protocols leak value. Projects like UniswapX or CoW Swap that outsource order flow to third-party solvers create a value leakage problem. They optimize for price but cede control of the execution layer, turning their own user transactions into a public subsidy for searchers and builders.
Internalization builds a proprietary pipeline. Protocols like dYdX v4 or Aevo that operate their own sequencer and orderbook internalize the full transaction lifecycle. This converts the MEV supply chain from a public good into a private, monetizable pipeline, capturing fees from matching, bundling, and cross-domain arbitrage.
The counter-intuitive result is protocol-owned liquidity. By owning execution, a protocol transforms its order flow into a strategic asset. This attracts professional market makers who pay for exclusive access, creating a flywheel where captured MEV funds protocol development and user incentives, unlike the extractive model of Ethereum's public mempool.
Evidence: The L2 revenue model. Arbitrum and Optimism now generate millions in sequencer revenue from internalized cross-domain arbitrage and liquidations. This demonstrates that the real value accrues not to the application logic, but to the entity that controls the sequencing and finality of the state transition.

THE MISDIRECTION
Steelman: Isn't Redirecting Value to Users the Point?
Reframing MEV extraction as 'user value' is a dangerous narrative that entrenches the very problem it claims to solve.
MEV-Aware protocols are rent-seeking middlemen. They don't eliminate extraction; they institutionalize it. Protocols like UniswapX and CowSwap embed MEV searchers into their core settlement logic, creating a sanctioned cartel.
This creates a moral hazard. The protocol's incentive shifts from minimizing user loss to maximizing its own cut of the extracted value. It's a tax, rebranded as a rebate.
The 'value' is a leaky bucket. Studies of intent-based systems show significant value still bleeds to block builders and proposers. The user's 'better price' is a fraction of the total MEV their transaction created.
Evidence: Flashbots' SUAVE aims to be the ultimate MEV-aware infrastructure, not its abolisher. Its success would cement MEV as a permanent, protocol-level cost of doing business.

MEV-AWARE PROTOCOLS
TL;DR for Builders and Architects
Current 'MEV-aware' designs often optimize for searcher efficiency, inadvertently centralizing value capture and creating systemic fragility.
01
The Problem: Order Flow Auctions (OFAs) as a Subsidy
Protocols like UniswapX and CowSwap outsource order routing to solvers, creating a centralized auction layer. This:
- Centralizes Power: A few sophisticated solver pools (e.g., CoW DAO, 1inch) capture most value.
- Creates Opaque Markets: The 'best execution' for users is determined in a private, off-chain auction.
- Feeds the Beast: It professionalizes MEV extraction rather than eliminating it, making the system dependent on solver profitability.

The Problem: Intents as a Centralization Vector
Intent-based architectures (e.g., Anoma, Across, UniswapX) shift complexity from users to fillers. The result:
- Validator/Solver Oligopoly: Fulfilling complex intents requires capital and sophisticated software, favoring large, centralized actors.
- Liquidity Fragmentation: Solvers must lock capital across chains, creating barriers to entry and reducing competition.
- Protocol Risk: User experience and security are now outsourced to a small set of third-party fillers.

The Solution: Credibly Neutral Settlement
The endgame is protocols that enforce fair execution at the consensus or settlement layer, not via off-chain auctions. This requires:
- In-Protocol Ordering Rules: Like Chainlink FSS or threshold encryption schemes to neutralize frontrunning.
- Force-Inclusion Lists: Guaranteeing transaction inclusion without bidding wars (e.g., Ethereum's PBS ideals).
- Builder-Base Separation: Decoupling block building from proposal to prevent vertical integration of MEV supply chains.

The Solution: Minimize Trusted Components
Architect for verifiability, not optimization. Every off-chain component is a potential cartel.
- Succinct Proofs: Use ZKPs to verify execution correctness of complex intents, reducing reliance on honest solvers.
- Permissionless Validation: Design filler roles to be permissionless and bond-based, not whitelisted.
- Transparent Economics: All fees and arbitrage profits should be transparent and contestable on-chain, not hidden in private order flow deals.
