Warning to builders: L2s are leaking value, L1 appchains are the smarter bet | Opinion

Layer-2 chains were supposed to be the next evolution of blockchain scalability, and in some ways, they delivered. They made transactions faster and cheaper, helped projects scale rapidly, and gave Ethereum (ETH) room to breathe amid a surge in network activity. But as the dust settles, one uncomfortable truth has become hard to ignore: L2s donât retain the value they generate. Instead, they leak it back to the parent chain, back to the liquidity hubs, and back to governance structures that were never really theirs to begin with.

This might not have been a problem in 2021, when projects raced to achieve speed and scale above all else. But weâre in a different cycle now, and the number of projects competing for users has increased exponentially. Projects now have to think long-term. Theyâre optimizing for sustainability, sovereignty, and alignment. And increasingly, theyâre turning to app-specific âappchainâ layer 1sânot as a novelty, but as a necessity.
L2s: Fast, cheapâand economically hollow
Letâs call it like it is: L2s are downstream environments. They inherit security, settle transactions, and rely on Ethereum (or another L1) to finalize everything that matters. That dependency has economic consequences.
Every time a transaction is processed on an L2, it eventually gets rolled up and settled on the L1. The result? Fees flow back to Ethereum. Data availability fees flow back to Ethereum. MEV valueâalso upstream. Itâs a one-way transfer of value, from the L2âs economy back to the L1 that secures it. If youâre building a project on an L2, youâre not compounding value in your own ecosystemâyouâre subsidizing someone elseâs.Â
While these charges may seem trivialâafter all, theyâre just a tiny percent of the networkâs revenueâthey add up quickly, endlessly sapping away liquidity. For any project trying to scale, these persistent overheads can seriously limit growth and long-term sustainability.
While these fees may appear minorâjust a small fraction of overall revenueâthey accumulate fast, quietly draining liquidity from the ecosystem. Over time, costs from the data availability and restaking layers become substantial. For any project approaching scale, these persistent overheads can seriously limit growth and long-term sustainability.
And it doesnât stop with fees. Liquidity and governance are also rooted in the parent chain. Most DeFi protocols still rely on liquidity pools and bridges based on the Ethereum mainnet. Token holders often stake or vote using systems built upstream. Even when L2s have their own tokens, theyâre often structurally tied to Ethereumâs economic and political dynamics.
Put differently: L2s give you speed, but they take away your independence and slowly drain your token economy of resources.
Appchain L1s: Keeping the value you create
Appchains, in contrast, are built to retain the value they generate. When you launch your own sovereign chain, youâre not settling elsewhere. Youâre not leaking fees or depending on another networkâs validator set. The economic activity you generateâtransaction fees, staking rewards, MEV, governance powerâit all stays local.
That creates a fundamentally different growth model. Instead of value flowing out of your ecosystem, it compounds internally. Your token captures more utility. Your community has a direct stake in your chainâs success. Your infrastructure becomes an engine for growth, not a cost center feeding another chainâs economy.
You also get full-stack control, no longer bound by a parent chainâs limitations. Want to set custom validator incentives? Go for it. Want to experiment with gasless transactions or dynamic tokenomics? Do it. L1s let you build infrastructure that matches your applicationâs needs, not the other way around.
But what about fragmentation?
For years, the biggest knock against appchains was that theyâd create isolated ecosystems. That criticism used to hold weight, but not anymore.
Thanks to interoperability solutions like LayerZero, Avalanche Warp Messaging, and IBC, we now have reliable ways to move data and assets across chains. Appchains can plug into broader ecosystems while still keeping their sovereignty. They can be both connected and independentâno longer forced to choose between integration and control.
The fragmentation argument is outdated. In practice, appchains are becoming a natural extension of the multichain world, and the tooling around them is improving fast.
The market is catching on
More and more projects are choosing to go the appchain route, and the trend will continue to gain steam. Builders want autonomy, they want economic sustainability, and they want the freedom to design their infrastructure around their users, not around Ethereumâs bottlenecks.
Thatâs not to say L2s are going away. For many early-stage projects, theyâre a decent starting point. But theyâre not built for scale. Theyâre not designed to retain value. And theyâre definitely not built for projects that want sovereignty over their infrastructure and their economy.
If youâre trying to build something enduringâsomething thatâs not just fast and cheap, but aligned, sovereign, and sustainableâyou shouldnât be settling for a Layer 2. You should be thinking like an ecosystem manager. You should be owning your stack. You should commit to building a chain that meets your own custom needs, without siphoning resources.Â
Spinning up an L2 may seem like the simplest go-to-market strategy, offloading responsibilities so you can get to market faster, but investing in L1 infrastructure is acrucialstep to long-term success. Before long, every project will be racing to build its own appchain.Â
