Have you ever wondered what it feels like to build something incredible, only to watch its value slip away to someone else’s system? That’s the reality for many crypto projects on Layer 2 (L2) blockchains today. When I first dove into the world of blockchain development, I was captivated by the promise of L2s—faster transactions, lower costs, and a way to scale Ethereum without breaking the bank. But the more I explored, the more I realized something wasn’t adding up. The value created on L2s often flows right back to the parent chain, leaving projects in a constant struggle to retain what they’ve built. That’s when I started looking at Layer 1 (L1) appchains, and let me tell you, it’s like discovering a hidden gem in the crypto world.

The Shift to L1 Appchains: A Smarter Path for Builders

The crypto landscape is evolving at breakneck speed, and builders are no longer just chasing speed or cost. They’re after control, sustainability, and the ability to keep the value they generate. L2s, while revolutionary in their own right, are starting to show their limitations. Meanwhile, L1 appchains—custom-built, application-specific blockchains—are emerging as the go-to solution for projects that want to own their future. In this article, we’ll dive into why L2s are leaking value, how L1 appchains solve this problem, and why the market is shifting toward these sovereign chains. Buckle up; this is going to be a deep dive into the future of blockchain development.


The Hidden Cost of Layer 2s: Where Value Slips Away

Let’s start with the basics. L2s were designed to solve Ethereum’s scalability woes. They process transactions off-chain, bundle them up, and settle them on the Ethereum mainnet, making things faster and cheaper. Sounds great, right? But here’s the catch: every transaction on an L2 eventually ties back to the Layer 1 parent chain. This dependency creates a subtle but significant problem—value leakage.

Every time an L2 processes a transaction, it pays fees to settle on Ethereum. These data availability fees might seem small, but they add up fast. For a high-traffic project, these costs can become a constant drain, pulling resources out of the ecosystem. And it’s not just fees. Maximum Extractable Value (MEV), the profit validators make by reordering transactions, also flows upstream to the L1. If you’re building a decentralized app (dApp) on an L2, you’re essentially subsidizing Ethereum’s economy while your own takes a hit.

“L2s are like renting an apartment—you get the space, but you’re still paying the landlord’s mortgage.”

– Blockchain developer

Beyond economics, there’s a governance issue. Most L2s rely on Ethereum’s infrastructure for liquidity pools, staking mechanisms, and even voting systems. This means your project’s token, no matter how innovative, is tethered to Ethereum’s rules and dynamics. It’s like trying to run a business while someone else controls your budget. For early-stage projects, this might be fine, but for those aiming for long-term growth, it’s a recipe for dependency.

Why L1 Appchains Are a Game-Changer

Now, let’s talk about the alternative: L1 appchains. These are standalone blockchains built specifically for a single application or ecosystem. Unlike L2s, they don’t rely on a parent chain for security or settlement. Instead, they’re fully sovereign, meaning all the value generated—fees, staking rewards, MEV—stays within the ecosystem. This is a big deal, and here’s why.

When you run an appchain, you’re not just renting space; you’re building your own house. Every transaction fee, every staking reward, every bit of economic activity compounds within your ecosystem. Your token becomes the centerpiece, driving utility and aligning incentives for your community. It’s a model that screams self-sufficiency and long-term growth.

  • Economic Control: Keep transaction fees and rewards in-house.
  • Custom Infrastructure: Tailor your blockchain to your app’s needs.
  • Community Alignment: Your token holders have a direct stake in your success.

Perhaps the most exciting part? You get to design your chain from the ground up. Want to experiment with gasless transactions? Go for it. Need custom validator incentives to attract top talent? No problem. With an L1 appchain, you’re not bound by Ethereum’s constraints. You’re free to innovate in ways that L2s simply can’t match.

Breaking the Fragmentation Myth

One of the biggest arguments against appchains has always been fragmentation. Critics say standalone chains create isolated ecosystems, cut off from the broader crypto world. A few years ago, that might’ve been true. But today? That argument doesn’t hold water.

Interoperability protocols have changed the game. Tools like cross-chain bridges and messaging systems allow appchains to connect seamlessly with other networks. You can move assets, share data, and integrate with larger ecosystems without sacrificing your sovereignty. It’s like having your own private island with a high-speed ferry to the mainland.

In my opinion, this is where the crypto world is heading—a multichain universe where appchains coexist, connected yet independent. The fear of fragmentation feels like a relic of the past, especially when you see how fast interoperability solutions are improving.

The Market’s Shift: Why Builders Are Choosing L1s

Look around, and you’ll see the trend picking up steam. More projects are launching their own appchains, and it’s not just the big players. From DeFi protocols to gaming platforms, builders are realizing that L1s offer something L2s can’t: ownership. When you control your stack, you control your destiny.

This shift isn’t just about economics—it’s about vision. Builders want to create ecosystems that reflect their values and priorities. They’re tired of playing by someone else’s rules. And honestly, who can blame them? If you’re pouring your heart into a project, why let another chain siphon off your success?

When Should You Choose an L2?

Let’s be fair—L2s aren’t useless. For early-stage projects or those with limited resources, they’re a solid starting point. They’re quick to deploy, cost-effective, and let you tap into Ethereum’s massive liquidity and露

ecosystem without building your own chain from scratch. But as your project grows, the limitations of L2s become harder to ignore. If you’re planning for the long haul, an L2 might feel like a pair of training wheels—helpful at first, but restrictive once you’re ready to ride on your own.

“Start with an L2 if you must, but plan for an L1 if you want to own your future.”

– Crypto strategist

That said, L2s still have their place. They’re ideal for testing ideas, launching MVPs, or tapping into an existing user base. But if your goal is to build a sustainable, self-contained ecosystem, you’ll eventually outgrow them.

The Practical Side: Building Your Own Appchain

So, you’re sold on the idea of an L1 appchain. Now what? Building one isn’t as daunting as it sounds, especially with modern tools. Platforms like Cosmos, Polkadot, or Avalanche make it easier than ever to spin up a custom chain. You’ll need to consider a few key steps:

  1. Define Your Needs: What does your app require? Custom tokenomics? Unique governance? Map it out.
  2. Choose a Framework: Pick a platform that aligns with your technical and economic goals.
  3. Secure Validators: Build a network of validators to ensure security and decentralization.
  4. Integrate Interoperability: Use cross-chain tools to stay connected to other ecosystems.
  5. Launch and Iterate: Start small, test, and scale as your community grows.

It’s not a weekend project, but it’s an investment in your project’s future. Think of it like planting a tree—hard work now, but it’ll bear fruit for years to come.

The Future Is Multichain

Here’s where things get exciting. The crypto world isn’t heading toward a single dominant chain—it’s becoming a vibrant, interconnected web of appchains. Each project can have its own sovereign L1, tailored to its needs, while still plugging into the broader ecosystem. It’s the best of both worlds: independence and connectivity.

In my experience, the most successful projects are those that think like ecosystems, not just apps. They build infrastructure that serves their users, not someone else’s chain. As interoperability improves, the barriers to entry for appchains will keep dropping, and we’ll see an explosion of custom L1s in the coming years.

So, what’s the takeaway? If you’re a builder, don’t settle for a system that drains your value. An L1 appchain might take more effort, but it’s a strategic move that pays off in control, sustainability, and growth. The future of crypto isn’t about renting space on someone else’s chain—it’s about owning your own.


The choice between L2s and L1 appchains comes down to one question: Do you want to rent or own? For projects with big ambitions, the answer is clear. Start planning your appchain today, and build a future where your value stays where it belongs—with you.
