Searchers are the new market makers. Traditional market making relies on passive, pre-committed liquidity. Modern searchers, using solvers like those in UniswapX and CowSwap, actively source and route liquidity across venues, creating dynamic, execution-time markets.
Why Searchers Are Becoming the New Market Makers
An analysis of how MEV searchers, through arbitrage and liquidations, have usurped the price discovery and liquidity functions of traditional market makers, creating a new, extractive financial primitive.
Introduction
The rise of generalized intent solvers is transforming searchers from passive data miners into the primary liquidity providers and risk-takers of the on-chain economy.
This shift flips the liquidity model. Instead of LPs providing static capital, searchers' algorithms provide dynamic capital commitment, optimizing for cross-domain arbitrage and MEV extraction. This creates more efficient price discovery than traditional AMM pools.
The evidence is in solver economics. On CowSwap, a specialized intent-based DEX, competing solvers now handle over 70% of trade volume, generating profits by finding superior execution paths that centralized exchanges and simple AMMs cannot match.
Executive Summary: The New Liquidity Stack
The MEV supply chain is evolving from a parasitic extractor into the foundational liquidity layer for all on-chain activity.
The Problem: JIT AMMs Are Killing Passive LPs
Just-in-Time Liquidity bots front-run large swaps, providing and withdrawing capital in a single block. This extracts fees while leaving passive LPs holding the bag of toxic flow.
- Passive LP returns are down ~30-50% on major DEXs due to adverse selection.
- Creates a prisoner's dilemma where the only winning move is to become a searcher.
The Solution: Searchers as On-Demand Liquidity Engines
Searchers now compete to source the best price across all venues (Uniswap, Curve, Balancer) and private pools, acting as universal market makers.
- Reduces slippage by ~10-60% for end-users versus naive AMM routing.
- Capital efficiency skyrockets; $1 of searcher capital can facilitate $100+ in volume per block via flash loans.
The Architecture: Intent-Based Order Flow
Protocols like UniswapX, CowSwap, and Across abstract execution. Users submit intents ("I want X token for ≤ Y cost"), and searchers compete in a sealed-bid auction to fulfill it.
- Shifts risk from user to searcher (no failed tx, no front-running).
- Creates a $200M+ monthly market for execution quality, paid in saved gas and improved prices.
The Consequence: MEV is the New Spread
The profit from arbitrage and liquidation is no longer pure extraction; it's the fee for providing global liquidity and settlement assurance. This is the new spread.
- Validators and builders (via PBS) now capture and redistribute this spread as a core protocol revenue stream.
- Turns MEV from a network bug into a verifiable, auctioned resource.
The Infrastructure: SUAVE and the Future
Ethereum's SUAVE chain and shared sequencers (like those from Espresso, Astria) aim to formalize this stack. They create a neutral, competitive marketplace for block space and execution.
- Decouples trust from execution, preventing vertical integration by dominant builders.
- Enables cross-chain intent fulfillment as a primitive, challenging LayerZero and CCIP.
The Bottom Line: Liquidity is a Service
The end-state is LsAAS: Liquidity-as-a-Service. Passive, static capital in AMM pools is obsolete. The new stack is dynamic, competitive, and software-defined.
- Winners are searcher firms with best execution algos and relationships, not the largest token holders.
- Every DEX becomes an order flow aggregator, with the actual market making happening off-ledger.
The Core Argument: Liquidity as a Byproduct of Extraction
Searchers are not just order-takers; their profit-driven MEV extraction is the primary engine for on-chain liquidity.
Liquidity is a side effect. Traditional market makers provide liquidity for a spread. Searchers provide liquidity to capture value from price discrepancies, failed arbitrage, or cross-domain opportunities. Their activity is a byproduct of profit-seeking, not a service.
Searchers outcompete passive LPs. In Automated Market Makers (AMMs) like Uniswap V3, a searcher's JIT (Just-in-Time) liquidity attack provides deeper liquidity for a single block to capture LP fees, then vanishes. This dynamic liquidity is more capital-efficient than static LP positions.
The infrastructure proves the shift. Protocols like Flashbots' SUAVE and bloXroute's mev-commit are building blocks for a searcher-centric liquidity layer. These systems formalize the auction for block space where liquidity provision is the winning bid.
Evidence: On Ethereum, over 90% of MEV is arbitrage, which directly correlates to correcting prices across pools like Curve and Balancer. This constant, automated correction is the liquidity.
Market Context: The Vacuum and the Vultures
The collapse of centralized market makers created a structural liquidity gap that decentralized searchers are exploiting with superior technology.
Centralized market maker collapse created a vacuum. The implosion of firms like Alameda and 3AC removed billions in on-chain liquidity, fragmenting markets and widening spreads. This structural gap persists because traditional market makers are capital-inefficient on public mempools.
Searchers are the new liquidity providers. They operate as specialized, atomic agents using MEV bots and private RPCs like Flashbots to source and execute complex cross-domain arbitrage. Unlike traditional MMs, they provide liquidity as a byproduct of profit-seeking, not as a primary service.
The edge is execution, not capital. A searcher with a $50k wallet and a sophisticated JIT (Just-in-Time) liquidity strategy consistently outcompetes a $50M fund using slow, batched orders. This flips the traditional market-making paradigm where size was the primary moat.
Evidence: Onchain activity shows searcher-driven protocols like UniswapX and CowSwap now dominate large, cross-chain swap volume. Their fill rates and price improvement metrics exceed those of legacy RFQ systems, proving the model's superiority in a fragmented multi-chain world.

Deep Dive: The Mechanics of Extractive Liquidity
Searchers are replacing traditional market makers by algorithmically extracting value from fragmented liquidity across DeFi.
Searchers are the new MMs. Traditional market making relies on passive capital provision. Searchers use active, algorithm-driven strategies to identify and capture inefficiencies across venues like Uniswap, Curve, and Balancer, making liquidity a byproduct of profit-seeking.
The MEV supply chain enables extraction. Searchers operate within the MEV-Boost relay-builder ecosystem, using tools like Flashbots SUAVE to bundle and prioritize transactions. This infrastructure turns block space into a commodity they arbitrage.
Extractive liquidity is more capital efficient. A traditional MM must lock capital in pools. A searcher's capital is transient, deployed only for the milliseconds needed to execute a profitable cross-DEX arbitrage or liquidate a loan on Aave.
Evidence: On-chain data shows over 60% of large DEX swaps now involve searcher-driven routing through aggregators like 1inch or CowSwap, which internalize this extractive logic to find the best price.
Protocol Spotlight: Architecting for the Searcher Age
The MEV supply chain is evolving from a public nuisance into a formalized, competitive market, with searchers emerging as the primary liquidity architects.
The Problem: Blind Auctions and Inefficient Order Flow
Traditional block builders run sealed-bid auctions, creating a black box. Searchers have no visibility into execution quality, leading to wasted bids and suboptimal price discovery for users.
- Result: ~$100M+ in MEV is extracted monthly, but a significant portion is lost to inefficiency.
- Opportunity: Unlocking this value requires transparent, competitive markets for block space.
The Solution: Open Searcher Markets (e.g., SUAVE)
Protocols like Flashbots' SUAVE decentralize the block-building process by creating a dedicated mempool and auction house for searchers.
- Key Benefit: Searchers bid in open, real-time auctions for transaction ordering, driving execution quality up and costs down.
- Key Benefit: Enables complex, cross-domain MEV strategies, turning searchers into hyper-efficient cross-chain market makers.
The New Primitive: Intents and Express Relays
Searchers are the execution layer for intent-based architectures like UniswapX and CowSwap. Users submit outcome-based intents, and searchers compete to fulfill them optimally.
- Key Benefit: Users get better prices without managing complexity. Searchers capture value via sophisticated routing (e.g., Across, LayerZero).
- Key Benefit: Creates a $10B+ design space for application-specific searcher networks.
Jito: Validators as Searcher Infrastructure
Jito's Solana client bundles searcher transactions with priority fees, creating a liquid market for block space. Validators profit from MEV sharing, aligning incentives.
- Key Benefit: ~95% of Solana validators use Jito, proving the economic model works.
- Key Benefit: Provides searchers with predictable, low-latency execution environment, essential for high-frequency arbitrage.
The Risk: Centralization and Cartels
Efficient searcher markets concentrate power. The most sophisticated actors with the fastest infrastructure and largest capital can dominate, recreating the walled gardens of traditional finance.
- Result: Top 5 searcher firms capture over 60% of Ethereum MEV.
- Mitigation: Requires protocol-level design like distributed block building and commit-reveal schemes.
The Endgame: Searchers as L1/L2 Differentiators
Blockchain performance will be judged by its searcher ecosystem. Chains that offer superior tooling (EigenLayer, Espresso), fast finality, and fair access will attract the capital and liquidity that define a chain's economy.
- Key Benefit: A vibrant searcher market is a 10x multiplier for DeFi TVL and user experience.
- Key Benefit: Turns latency and composability into measurable competitive advantages.
Counter-Argument: Is This Sustainable?
The economic logic driving searcher dominance creates systemic risks that mirror the problems of traditional finance.
Economic centralization is inevitable. The capital requirements and technical sophistication for high-frequency MEV extraction create a winner-takes-most market. This concentrates power in a few firms like Jump Crypto or Wintermute, replicating the broker-dealer oligopoly from TradFi.
Protocols become price-takers. When a handful of searchers control the majority of block space on chains like Solana or Arbitrum, they dictate transaction ordering economics. This undermines the credible neutrality that decentralized networks promise to end-users.
The regulatory attack surface expands. A centralized searcher layer presents a clear target for agencies like the SEC, which can argue these entities act as unregistered exchange facilitators. This legal risk jeopardizes the entire MEV supply chain, from builders to validators.
Evidence: Flashbots' dominance on Ethereum post-Merge, where a single builder often produces over 90% of blocks, demonstrates this centralization pressure. The ecosystem's response, like SUAVE or MEV-Share, is an admission that the current model is not sustainable.
Future Outlook: The Professionalization of Extraction
Searchers are evolving from opportunistic bots into institutional-grade liquidity providers, fundamentally reshaping market structure.
Searchers are the new market makers. They provide the latency-sensitive, cross-domain liquidity that traditional MMs cannot. This shift moves the liquidity function from order books to the execution layer itself.
The business model is institutionalizing. Dedicated firms like Biconomy and PropellerHeads now run multi-chain searcher operations, investing in infrastructure that dwarfs simple MEV bots. This creates a professionalized extractive layer.
Intents formalize this role. Standards like UniswapX and CowSwap abstract execution to searchers, turning them into paid service providers. This is the commercialization of the mempool.
Evidence: Flashbots' SUAVE aims to be a decentralized block builder marketplace, explicitly creating a venue for searcher competition. This institutionalizes the role further.
Key Takeaways for Builders and Investors
The rise of searchers and intent-based architectures is unbundling the traditional market maker role, creating new infrastructure needs and investment opportunities.
The Problem: DEX Liquidity is Fragmented and Inefficient
On-chain liquidity is siloed across hundreds of chains and pools, creating massive arbitrage opportunities. Traditional market makers struggle with capital efficiency and cross-chain execution.
- Result: Billions in MEV extracted annually from simple DEX arbitrage.
- Opportunity: A new class of infrastructure to unify and route liquidity is required.
The Solution: Searchers as Just-in-Time Liquidity
Searchers, powered by sophisticated algorithms, act as dynamic, on-demand market makers. They fulfill user intents by sourcing liquidity across the entire ecosystem in real-time.
- Key Entities: This is the engine behind UniswapX, CowSwap, and Across.
- Builder Play: Create searcher SDKs, RPC endpoints with fast mempool access, and cross-chain messaging infra like LayerZero.
The Investment Thesis: Infrastructure for the Searcher Economy
The value accrual shifts from holding LP tokens to providing critical services to searchers. This creates a new stack.
- Layer 1: Fast, deterministic blockchains with native MEV management (e.g., Solana, Sei).
- Middleware: Specialized RPCs (Bloxroute), block builders (Flashbots), and intent solvers.
- Invest in primitives that reduce latency and increase searcher profitability.
The Risk: Centralization and Regulatory Overhang
Searcher dominance could lead to new centralization points. The most efficient block builders and RPC providers could form oligopolies, recreating the problems of traditional finance.
- Watch For: Builder cartels and exclusive order flow agreements.
- Mitigation: Invest in decentralized builder networks, SUAVE-like protocols, and transparent MEV auctions.
