Most conversations around rollups focus on speed, scalability, and lower fees. The assumption is simple: faster systems win. Yet this view leaves out a more important question. Who actually makes money in rollup ecosystems?
As layer 2 and layer 3 architectures gain traction, value is no longer concentrated at the base layer. It is being redistributed across new actors such as sequencers, data availability providers, and application-specific chains. Each layer introduces its own revenue streams, cost structures, and power dynamics.
Understanding rollups today requires more than a technical explanation. It requires a clear view of how money flows, where margins exist, and which players are positioned to capture long-term value.
This blog explains how value is created, distributed, and captured across layer 2 and layer 3 rollup ecosystems, with a focus on revenue flows, cost structures, and the players positioned to benefit in 2026.
How Value Flows Across the Stack
| Layer | Primary Function | Revenue Source | Cost Drivers |
|---|---|---|---|
| Layer 1 | Settlement and security | Gas fees | Validation and consensus |
| Layer 2 | Transaction execution | Fees, MEV | Data availability, infra |
| Layer 3 | Application layer | User payments, custom fees | Infra,integration |
The Rollup Stack: Key Economic Participants in Layer 2 and Layer 3
Rollups introduce a multi-layered system where value is distributed across specialized participants. Each layer plays a distinct role in transaction processing, data handling, and revenue capture. Understanding who participates in this stack is essential to understanding who makes money.
Sequencers
Sequencers are responsible for ordering transactions and producing blocks within a rollup.
- Control transaction inclusion and ordering
- Collect transaction fees from users
- Capture MEV by prioritizing transactions
In most current rollup designs, sequencers operate as centralized or semi-centralized entities, which allows them to capture a significant share of revenue.
Data Availability Providers
Data availability layers store transaction data so it can be verified and reconstructed when needed.
- Charge for storing and serving transaction data
- Enable rollups to reduce costs compared to storing all data on Layer 1
- Play a key role in scalability and cost efficiency
Projects building dedicated data availability layers have introduced new revenue streams tied to storage and bandwidth usage.
Settlement Layers
Layer 1 blockchains act as the final settlement layer for rollups.
- Provide security through consensus mechanisms
- Verify proofs and transaction data
- Collect base fees for settlement
While Layer 1 still captures value, its share of total revenue decreases as execution shifts to rollups.
Rollup Operators and RaaS Providers
Rollup operators manage the infrastructure required to deploy and maintain rollups.
- Offer rollup deployment services
- Handle upgrades, monitoring, and maintenance
- Generate revenue through service fees and subscriptions
The rise of Rollup-as-a-Service models has turned infrastructure into a recurring revenue business.
Applications and Layer 3 Chains
Layer 3 introduces application-specific chains built on top of rollups.
- Control user interactions and fee structures
- Capture value directly from end users
- Enable custom monetization models
This layer brings revenue closer to applications, reducing dependence on shared infrastructure.
Where Does the Money Flow in Layer 2 Rollups?
Layer 2 rollups generate revenue from multiple sources, but the distribution of that revenue is not evenly spread across participants. In most current systems, value concentrates around entities that control execution and transaction ordering.
Primary Revenue Sources in Layer 2
- Transaction Fees: Users pay fees to have their transactions processed within the rollup. These fees are typically lower than Layer 1 but occur at higher volume.
- Maximal Extractable Value: Sequencers can reorder, include, or exclude transactions to capture additional value. This creates a secondary revenue stream that can rival or exceed standard transaction fees in active markets.
- Infrastructure Fees: Operators and service providers charge for running nodes, APIs, and supporting infrastructure required by developers and applications.
Who Captures the Majority of Revenue?
In most Layer 2 architectures today, sequencers capture a significant portion of total revenue.
- They control transaction ordering
- They collect user fees
- They extract MEV opportunities
This concentration of control gives sequencers a dominant economic position within rollup ecosystems.
How Layer 3 Changes the Economics of Rollups
Layer 3 introduces a new shift in the rollup stack by moving control closer to applications. Instead of relying entirely on shared Layer 2 infrastructure, projects can build application-specific chains that define their own execution and monetization logic.
What Makes Layer 3 Different
Layer 3 sits on top of Layer 2 rollups and focuses on application-level customization.
- Dedicated execution environments for specific use cases
- Custom fee structures controlled by the application
- Greater flexibility in performance and user experience
This structure allows applications to operate with more control over both technology and revenue.
How Revenue Shifts in Layer 3
In Layer 2, value is largely captured by sequencers and infrastructure providers. Layer 3 changes this by enabling applications to capture a larger share of economic activity.
- Applications can set their own transaction fees
- Revenue flows directly from users to application operators
- Reduced dependence on shared sequencer economics
This creates a model where value is no longer concentrated at the infrastructure level.
New Monetization Models
Layer 3 enables new ways for applications to generate revenue:
- Subscription-based access models
- Embedded financial flows within applications
- Custom fee markets tailored to user behavior
These models go beyond traditional transaction fees and allow applications to align revenue with product design.
Trade-offs Introduced by Layer 3
Greater control comes with additional complexity.
- Increased infrastructure responsibility for application teams
- Dependence on the underlying Layer 2 for settlement and data
- Need to manage performance, security, and upgrades
This means not all projects will benefit equally from moving to Layer 3.

Layer 2 vs Layer 3 Economics
Layer 2 and Layer 3 operate within the same stack but differ in how control, revenue, and cost structures are distributed. Understanding these differences is key to identifying where value is created and captured.
Economic Comparison
| Factor | Layer 2 Rollups | Layer 3 Appchains |
|---|---|---|
| Execution Control | Managed by shared sequencers | Controlled by application |
| Revenue Capture | Sequencers, infra providers | Application owners |
| Fee Structure | Standardized across network | Custom, application-defined |
| MEV Capture | Primarily by sequencers | Can be internalized by application |
| Cost Structure | DA + settlement + infra | Infra + L2 dependency + ops |
| Flexibility | Limited by shared environment | High, tailored to use case |
| Margin Potential | Infra-driven | Product-driven |
Key Differences
Control
Layer 2 relies on shared infrastructure, which limits how much control individual applications have. Layer 3 allows applications to define execution rules and environments.
Revenue Flow
In Layer 2, revenue is concentrated at the infrastructure level. In Layer 3, revenue shifts toward applications that interact directly with users.
Flexibility and Design
Layer 2 provides a general-purpose environment. Layer 3 allows applications to customize performance, fees, and logic based on their needs.
Profitability Drivers
Layer 2 profitability depends on scale and infrastructure efficiency. Layer 3 profitability depends on product design, user engagement, and monetization strategy.
Cost vs Revenue: The Hidden Margin Dynamics
Revenue in rollup ecosystems is visible through transaction fees and MEV, but profitability depends on how costs are managed across the stack. In many cases, high revenue does not translate into strong margins.
Core Cost Components in Rollups
Data Availability Costs
Rollups must publish transaction data to ensure verifiability. This is often the largest expense, especially when using Layer 1 calldata.
Settlement Costs
Each batch of transactions must be settled on Layer 1, which requires paying gas fees for verification and finality.
Infrastructure and Operations
Running sequencers, nodes, APIs, and monitoring systems introduces ongoing operational costs.
Proof Generation
Zero-knowledge rollups require computational resources to generate proofs, adding another layer of cost.
Why Costs Matter More Than Revenue
- Rollups can process high transaction volumes, which increases gross revenue. At the same time, rising data availability and settlement costs can reduce net margins.
- Data from the Ethereum Foundation shows that calldata costs have historically formed a large portion of rollup expenses, directly affecting profitability.
- Upgrades such as EIP-4844 aim to reduce these costs by introducing blob-based data storage, which lowers the cost of publishing rollup data.
Why Most Rollup Discussions Miss the Economics
Most rollup discussions focus on metrics such as throughput, latency, and cost per transaction. These metrics explain performance, but they do not explain how value is created, distributed, or sustained. The result is a gap between technical progress and economic understanding.
Overfocus on Throughput and Scaling
Scaling has been the central narrative in blockchain development.
- Higher throughput is treated as the primary goal
- Lower fees are used as a benchmark for success
- Performance metrics dominate comparisons
These factors are important, but they do not reveal who captures revenue or how profits are distributed.
Limited Visibility Into Revenue Distribution
Rollup ecosystems involve multiple participants, each with different revenue streams.
- Sequencers capture transaction fees and MEV
- Data availability layers charge for storage
- Infrastructure providers earn service fees
- Applications generate user-driven revenue
Without analyzing these flows, it is difficult to understand where value actually accumulates.
Cost Structures Are Often Ignored
Many discussions highlight revenue growth without accounting for underlying costs.
- Data availability expenses can be significant
- Settlement costs impact margins
- Infrastructure operations require ongoing investment
Ignoring these factors creates an incomplete picture of profitability.
Focus on Technology Over Economics
Technical architecture often takes priority over economic design.
- Rollup types are compared based on performance
- Protocol upgrades are evaluated for efficiency gains
- Economic incentives receive less attention
This leads to systems that scale technically but lack clear value distribution models.
Who Will Capture the Most Value in 2026?
As rollup ecosystems mature, value is expected to concentrate around entities that control key layers of the stack rather than those that only participate in isolated functions. The shift is from open participation to controlled execution and coordinated infrastructure.
Sequencing and Execution Control
Entities that control transaction ordering and execution environments are positioned to capture consistent revenue through fees and MEV.
Infrastructure and Rollup Platforms
Providers offering rollup deployment, maintenance, and tooling generate recurring revenue and gain influence across multiple projects.
Application-Specific Chains
Applications that own their execution layer can monetize users directly and retain a larger share of economic activity.
Emerging Market Direction
- Control over execution layers is becoming more valuable than access to shared infrastructure
- Vertical ownership across multiple layers increases revenue capture
- Modular architectures distribute value, but also create competition between layers

Frequently Asked Questions
01. Who makes money in rollups?
Revenue in rollup ecosystems is generated by multiple participants. Sequencers capture transaction fees and MEV, data availability providers earn from storage services, infrastructure operators charge for deployment and maintenance, and applications generate revenue directly from users. The largest share today is often captured at the sequencing layer due to control over transaction ordering.
02. What is the role of sequencers in Layer 2 rollups?
Sequencers are responsible for ordering transactions and producing blocks within a rollup. They collect user fees and can extract additional value through MEV by prioritizing transactions. Their position gives them significant control over both execution and revenue flow.
03. How do Layer 2 and Layer 3 differ economically?
Layer 2 concentrates revenue at the infrastructure level, where sequencers and operators capture most of the value. Layer 3 shifts this dynamic by allowing applications to control execution and monetize users directly. This leads to more flexible revenue models and greater ownership at the application layer.
04. Are rollups profitable in 2026?
Profitability varies depending on architecture and scale. While rollups can generate high revenue through transaction fees and MEV, costs such as data availability, settlement, and infrastructure operations can reduce margins. Upgrades like EIP-4844 aim to reduce data costs, which may improve profitability over time.
05. What determines value capture in rollup ecosystems?
Value capture depends on control over key components such as sequencing, execution environments, and user interaction layers. Entities that control these elements are better positioned to capture revenue compared to those that only participate in isolated functions.
06. Do rollups reduce the importance of Layer 1 blockchains?
Rollups reduce the share of value captured at Layer 1 by moving execution off-chain. Layer 1 still plays a critical role in settlement and security, but its economic dominance decreases as more activity shifts to Layer 2 and Layer 3.
