MEV determines economic security. The revenue from transaction ordering and arbitrage is the primary subsidy for sequencer decentralization and validator staking yields. Rollups that fail to capture and manage this value leak it to external searchers and validators on the settlement layer.

The Future of Rollups Hinges on MEV Strategy
Rollups that treat sequencing as a commodity will fail. This analysis argues that successful L2s must implement native MEV capture and redistribution, turning a hidden tax into a sustainable user subsidy.
introduction
THE STAKES
Introduction
Rollup success is no longer a scaling contest; it is a competition for optimal MEV extraction and redistribution.
The strategy is a trilemma. Optimizing for maximal extractable value (MEV) creates a conflict between user experience, decentralization, and revenue capture. Fast, centralized sequencers like those on Arbitrum and Optimism maximize efficiency but create a single point of failure and censorship.
Intent-based architectures are the pivot. Protocols like UniswapX and CowSwap abstract execution, allowing users to express desired outcomes rather than transactions. This shifts the MEV competition from brute-force gas auctions to solver competition, potentially returning value to users.
Evidence: Over $675M in MEV was extracted on Ethereum L1 in 2023. Rollups like Arbitrum now consistently generate more sequencer revenue from MEV than from base transaction fees, proving the economic imperative for a deliberate strategy.

THE STRATEGIC IMPERATIVE
Executive Summary
Rollup success is no longer just about TPS and cost; it's a battle for credible neutrality and economic sustainability, with MEV as the central lever.
01
The Problem: MEV is a Public Good Crisis
Unchecked MEV extraction erodes user trust and creates systemic risks like chain reorgs. The value is captured by a few, while the network bears the externalities.\n- User Losses: Billions extracted annually via frontrunning and sandwich attacks.\n- Network Instability: Maximal Extractable Value (MEV) can incentivize harmful consensus-level behavior.

THE STRATEGIC IMPERATIVE
The Core Thesis: Sequencing is the New Moat
The long-term viability of a rollup is determined by its approach to transaction ordering and MEV capture.
Sequencer revenue dominates economics. The primary value capture for a rollup shifts from simple gas fees to the strategic ordering of transactions. This creates a persistent, protocol-native revenue stream that funds development and security.
Centralized sequencing is a temporary hack. Relying on a single, trusted sequencer like many L2s today creates a centralized point of failure and capture. This model will not survive against decentralized alternatives like Astria or shared sequencing layers.
MEV strategy defines competitive positioning. A rollup must choose its MEV policy: maximal extraction (like early Ethereum), redistribution (via Flashbots SUAVE), or minimization (like Aztec). This choice dictates its developer and user appeal.
Evidence: Arbitrum sequencer profits have exceeded $100M, validating the thesis. Projects like dYdX building their own chain prioritize full MEV control, proving sequencing sovereignty is non-negotiable for top-tier apps.
market-context
THE INCENTIVE MISMATCH
The Current State: Lazy Rollups and L1 Rent-Seekers
Today's rollup economics are broken, with sequencers capturing value while L1s extract rent, creating a strategic vulnerability.
Sequencers capture all MEV while providing minimal value. They run centralized, permissionless ordering nodes, extracting arbitrage and frontrunning profits without sharing them with the rollup's security providers or users.
L1s are passive rent-seekers in this model. Ethereum collects fees for data blobs and proofs but gains no economic upside from the application-layer value its security enables, creating a fundamental misalignment.
This creates lazy rollups. Protocols like Arbitrum and Optimism optimize for short-term developer adoption by subsidizing costs, not for long-term economic sustainability or MEV resistance.
Evidence: Over 90% of Arbitrum and Optimism sequencer profits come from MEV, not transaction fees, yet $0 of this flows back to Ethereum stakers or the rollup's own treasury.

THE ARCHITECTURAL IMPERATIVE
The Mechanics of Native MEV Capture
Rollup economic sustainability depends on designing the sequencer to directly extract and redistribute value from transaction ordering.
Native MEV capture is non-optional. A rollup that outsources sequencing to a generic L1 or a third-party network cedes its primary revenue stream. This transforms the sequencer from a profit center into a cost center, undermining long-term viability.
The design is a public good auction. Protocols like Flashbots' SUAVE envision a standardized block-building market. A rollup must architect its sequencer to receive sealed bids from searchers, creating a transparent and efficient price discovery mechanism for block space.
This counters validator extractable value (VEV). Without a formalized capture mechanism, value leaks to centralized sequencer operators or L1 validators through off-chain deals. Native capture internalizes this value for protocol treasury or user rebates.
Evidence: Arbitrum's sequencer generates ~$1M monthly in pure ordering profit, a figure that will grow with adoption. Rollups ignoring this are subsidizing their operators with future-state revenue.

MEV STRATEGY
The Vanguard: Who's Building the Future?
The next phase of rollup scaling is not about TPS; it's about who controls the value flow. These teams are re-architecting the stack to capture, redistribute, or eliminate MEV.
01
Espresso Systems: The Shared Sequencing Cartel
The Problem: Isolated rollup sequencers create fragmented liquidity and are vulnerable to centralization and censorship. The Solution: A decentralized, shared sequencing layer that batches transactions across rollups like Arbitrum and Optimism, enabling atomic cross-rollup composability and democratizing MEV capture.
- Key Benefit: Enables cross-rollup arbitrage as a public good, not a private extractor's game.
- Key Benefit: Provides decentralized censorship resistance via a Proof-of-Stake validator set.

Astria: The Bare-Metal Sequencing Layer
The Problem: Rollup teams waste cycles re-implementing centralized sequencers, which become immediate points of failure and rent extraction. The Solution: A dedicated, shared sequencer network that offers rollups a plug-and-play, decentralized block building layer, separating execution from sequencing.
- Key Benefit: Rollups like dYmension deploy in hours, not months, without MEV ops overhead.
- Key Benefit: Native integration with builders like Flashbots SUAVE for optimized block construction.

Flashbots SUAVE: The Universal MEV Marketplace
The Problem: MEV supply chains are opaque and inefficient, locked within single chains like Ethereum. The Solution: A decentralized mempool and block builder network that spans multiple chains and rollups, creating a competitive, transparent market for transaction ordering.
- Key Benefit: Enables intent-based bridging and trading across domains (e.g., UniswapX, Across).
- Key Benefit: Prevents frontrunning by default, returning value to users and dapps.

Radius: Encrypted Mempool as a Primitve
The Problem: Transparent mempools are a free-for-all for searchers, leading to rampant frontrunning and toxic MEV that harms users. The Solution: A rollup-agnostic encrypted mempool using Practical Verifiable Delay Encryption (PVDE), forcing fair, sealed-bid auctions for block space.
- Key Benefit: Eliminates frontrunning and sandwich attacks at the protocol level.
- Key Benefit: Preserves composability and fast finality (~1-2s) without sacrificing privacy.

Optimism's Law of Chains & Superchain
The Problem: Without coordination, a multi-rollup future defaults to a winner-take-all MEV landscape dominated by the most centralized sequencer. The Solution: A constitutional framework (Law of Chains) and shared technical stack (OP Stack) that mandates MEV mitigation and sequencer decentralization as core tenets for all Superchain members.
- Key Benefit: Enshrines credibly neutral sequencing as a non-negotiable standard.
- Key Benefit: Aligns economics via retroactive public goods funding from sequencer profits.

The Sovereign Rollup Endgame (Fuel, Celestia)
The Problem: Settlement-layer-centric models (like Ethereum) inherently limit sovereignty and force MEV strategies into an L1's design constraints. The Solution: Sovereign rollups using Celestia for data availability and Fuel as an execution layer take full responsibility for their transaction ordering, enabling radical MEV experimentation.
- Key Benefit: Ultimate flexibility to implement novel PBS, encrypted mempools, or full MEV burn.
- Key Benefit: Eliminates L1 consensus-level MEV leakage, capturing all value locally.

THE CENTRALIZATION TRAP
The Decentralization Counterargument (And Why It's Wrong)
The belief that pure decentralization solves MEV is a naive distraction from the real strategic imperative.
Sequencer decentralization is insufficient. A decentralized set of sequencers still creates a centralized point of MEV extraction. The real power lies in controlling the block-building logic, not just the right to propose blocks.
MEV strategy dictates economic security. A rollup's validator set stability depends on sustainable revenue. Without a formalized MEV distribution mechanism, validators are incentivized to run proprietary, off-chain MEV auctions, re-centralizing power.
Compare Arbitrum BOLD to Espresso. Arbitrum's BOLD focuses on decentralized fraud proofs for sequencing, but its MEV market remains informal. Espresso Systems provides a shared sequencer with integrated PBS, explicitly designing for MEV redistribution from day one.
Evidence: The Lido precedent. In Proof-of-Stake, decentralized staking pools like Lido still create centralization risks via governance and fee extraction. A decentralized sequencer set with a black-box MEV auction repeats this error at the execution layer.

MEV STRATEGY IS CRITICAL
Execution Risks and Pitfalls
The long-term viability of a rollup is determined by how it manages the economic and security externalities of Maximal Extractable Value.
01
The Centralizing Force of Builder Cartels
Permissionless sequencing is a myth if a few builders like Flashbots or bloxroute dominate block construction. This leads to censorship risk and value leakage to L1.
- Risk: Top 3 builders control >60% of blocks on major chains.
- Pitfall: L2 sequencer profits are extracted by L1 actors, undermining the rollup's economic security.

In-Session MEV and User Exploitation
Without proactive management, rollups become a playground for generalized frontrunning and sandwich attacks, directly harming end-users.
- Problem: Native AMMs like Uniswap V3 are vulnerable without protection.
- Solution: Integrate MEV-aware RPCs (e.g., Flashbots Protect) or enforce fair ordering at the sequencer level.

The PBS (Proposer-Builder Separation) Mandate
Rollups must architect for PBS from day one to separate block building from proposing. This is non-negotiable for credible neutrality.

Cross-Domain MEV as a Revenue Source
Ignoring cross-chain arbitrage (e.g., between Arbitrum and Optimism) leaves value on the table for external searchers. Rollups should capture and redistribute this value.
- Opportunity: Use a shared sequencer (like Astria or Radius) to internalize cross-rollup arbitrage.
- Model: Redirect captured MEV to a public goods fund or as sequencer revenue to subsidize fees.

Data Availability as an MEV Attack Vector
Cheap, unreliable DA layers (e.g., some EigenDA or Celestia configurations) enable time-bandit attacks. Sequencers can reorg chains after seeing future MEV opportunities.
- Risk: Weak DA guarantees break rollup safety assumptions.
- Mitigation: Enforce strong data availability or implement fraud proofs faster than MEV extraction windows (~1-2 minutes).

Intent-Based Architectures Are Inevitable
Traditional transaction queues are obsolete. The end-state is users submitting intents (as seen with UniswapX and CowSwap) to a solver network.

- Impact: Radically reduces toxic MEV (sandwiching) and improves UX through gas sponsorship and guaranteed execution.

THE MEV DIVIDE
The 2025 Landscape: Winners and Losers
Rollup success will be determined by which chains capture and redistribute value extracted from MEV.
Winning rollups subsidize users. They will implement proposer-builder separation (PBS) and encrypted mempools to sequester MEV. This captured value funds L2 gas subsidies or direct airdrops, creating a self-reinforcing economic flywheel that attracts the next wave of applications and users.
Losing rollups leak value. Chains that ignore MEV strategy become extractive fee markets for sophisticated searchers. Their high, volatile gas fees and unpredictable execution deter mainstream adoption, ceding developer mindshare to chains with formalized MEV capture like Arbitrum and its upcoming BOLD fraud proof system.
The infrastructure war is settled. Rollups will standardize on SUAVE-inspired block building or Flashbots Protect-style RPCs. The shared sequencer narrative fails; control over block construction and ordering is the ultimate moat. Espresso Systems and Astria compete to provide this as a service.
Evidence: Optimism's RetroPGF and Arbitrum's STIP prove that sustainable, MEV-funded public goods are viable. Chains without this mechanism rely on inflationary token emissions, a model that collapses when the subsidy ends.
