Ethereum has recently faced significant challenges. Market sentiment has been low, with critics quick to point out ETH's underperformance compared to SOL, largely attributing this to the growing market share and user migration to Layer 2 (L2) solutions.
This situation raises a critical question: are L2s part of Ethereum? As with most topics in the crypto space, the answer is a blend of complexity and simplicity. This article explores both sides of the argument and examines the dynamic between Ethereum and its L2 ecosystem.
The Foundation of Ethereum’s Rollup-Centric Roadmap
From the beginning, L2s have been central to Ethereum’s rollup-centric scaling strategy. They were conceived as extensions of Ethereum—both technically and culturally—aimed at enhancing its capabilities and attracting a broader user base.
At their core, L2s are deeply intertwined with Ethereum. They share Ethereum’s DNA, relying on ETH as a native currency, benefiting from Ethereum’s security guarantees, and utilizing it for data storage and settlement. This relationship resembles a startup leveraging the infrastructure and brand recognition of its parent company—a win-win scenario for both parties.
The symbiotic connection between L2s and Ethereum is undeniable. L2s thrive by building on Ethereum's infrastructure and security, while Ethereum gains from increased activity and demand for ETH, reinforcing its role as a store of value.
How Layer 2 Solutions Enhance Ethereum
By offering lower fees and faster transaction times, L2s make it easier for developers to build a wider range of applications. Consider the explosion of memecoins on Base or the rise of SocialFi platforms like Farcaster, which have opened up new markets and user experiences.
Moreover, L2s are becoming central hubs for DeFi activity, with ETH and ETH-related assets at the heart of these ecosystems. Just look at the numbers: chains like Arbitrum, Optimism, and Base are dominated by assets tied to ETH.

The Concerns: Could L2s Break Away from Ethereum?
One major criticism of the rollup-centric approach is the possibility that L2s might eventually stop relying on Ethereum. While the relationship currently appears strong, what if L2s decide to build their own empires and cut ties with Ethereum? This could mean no longer depending on Ethereum for security, abandoning ETH as gas, or even ceasing to use Ethereum’s block space.
The fear of "L2 breakaway" is not entirely unfounded. Technically, L2s could build independent ecosystems with their own validators, controlling the entire modular blockchain stack. But is a messy breakup between L2s and Ethereum inevitable? Not necessarily.
Creating a new ecosystem or launching a separate L1 blockchain is complex and resource-intensive. Bootstrapping a validator set is a significant challenge, and building a new L1 could mean facing the same scalability issues Ethereum currently encounters. If L2s intended to go down this path, they likely would have done so from the start.
The Real Focus of Layer 2 Builders
Instead, L2 builders are playing a different game. Their primary focus is on scaling transactions, attracting developers, incentivizing application development for various use cases, and onboarding new users into crypto—while Ethereum handles security and decentralization.
This doesn’t mean the L2 landscape is free from issues. There’s a strange paradox at play: the proliferation of L2s demonstrates the success of the rollup-centric roadmap, yet it is also a source of fragmentation.
There is broad agreement that there may be too many L2s. Too many lookalikes, too little differentiation. It’s like a thousand startups chasing the same market, all promising the same things—an unsustainable and unhealthy scenario.
What we need are meaningful L2s—those that offer something unique and different. Innovation in security, application diversity, and go-to-market strategies is essential.
The Bigger Picture: Maintaining a Cohesive Ecosystem
As Ethereum scales through L2s, it’s vital that the ecosystem continues to feel like Ethereum. We must avoid the trap of fragmentation, where everyone is pulling in their own direction.
L2s need to be seamlessly connected. Teams are developing technical stacks aimed at creating unified networks of chains that share resources and offer users a smoother, faster experience—initiatives like Superchain, AggLayer, Elastic Chain, and Orbit Chains are promising steps in this direction.
However, we must be cautious of "echo chambers." These chain ecosystems shouldn’t become isolated universes. A healthy L2 environment is one where chains work together, not in isolation. We need bridges, not moats.
Collaboration, communication, education, and incentives are key. We must build shared infrastructure and standards that enable seamless interaction between L2s. Only then can we truly achieve mutual success.
Frequently Asked Questions
What is the relationship between Layer 2 and Ethereum?
Layer 2 solutions are scaling platforms built on top of Ethereum. They rely on Ethereum for security and settlement while processing transactions off-chain to improve speed and reduce costs, creating a symbiotic relationship.
Can Layer 2 networks operate without Ethereum?
While it's technically possible for L2s to become independent, doing so would require building a new security model and validator set—a complex and costly process. Most L2s continue to rely on Ethereum for critical functions.
Why are there so many Layer 2 solutions?
The large number of L2s stems from high demand for scalable blockchain solutions. However, this has led to fragmentation, and the market will likely consolidate around networks that offer real innovation and user value.
How do Layer 2 solutions benefit Ethereum users?
L2s offer faster and cheaper transactions, enabling broader adoption and new use cases like gaming and social finance, all while leveraging Ethereum’s security and decentralization.
What is being done to unify Layer 2 ecosystems?
Projects like Superchain and AggLayer are working to create interconnected L2 networks, allowing users and developers to interact across multiple chains without friction.
Are Layer 2 solutions secure?
Most L2s derive their security from Ethereum. However, users should still research individual networks, as security models can vary based on design and implementation.
Conclusion: Beyond a Zero-Sum Game
It’s possible to argue that L2s are not Ethereum—or even an extension of it. But what’s undeniable is that L2s enhance the utility of both Ethereum and ETH.
The "L2 vs. Ethereum" debate is a false dichotomy. This isn’t a zero-sum game. In the end, Ethereum and L2s are in the same boat. Let’s focus on building a future where both can thrive together in a symbiotic relationship, driving the entire crypto ecosystem forward.
