Blockchains are changing all the time. As they change, new layers appear to fix problems that older ones cannot solve very well. After L2 became more common, people started talking more about the next layer.
In this article, we explain what Layer 3 means, how it connects to blockchain scaling, and why more projects are using it. We also show real examples of projects and what to pay attention to when comparing Layer 3 crypto projects.

What Is Layer 3 Blockchains?
A Level 3 blockchain (L3) sits on top of a Layer 2 and is designed for a specific goal, for example, gaming, DeFi apps, payments, or cross-chain tools.
You can look at how the layers are set up:
- Layer 1 keeps the network secure and confirms transactions
- Layer 2 makes transactions quicker and cheaper
- Layer 3 is where apps are improved for users and real business needs
Level 3 gives teams full control over how an app behaves. They can change costs, improve speed, set their own rules, and add compliance features when needed. It makes apps smoother and easier to use.
Layer 3 vs Layer 2: Key Differences
L2 and L3 are built for different reasons: Layer 2 is mainly about solving blockchain limitations (like speed and high costs). Third Level uses this improved base to make apps easier to use. Here are other important points:
- Level of operation: Layer 2 works like a common space where many apps work together. Everyone uses the same system. Layer 3 works closer to each app, or to a small group of apps, giving more control over how things work.
- How flexible it is: L2 does not allow many changes because apps share the same environment. Third Level lets developers change fees, rules, and how the application feels to users. This is very common in games and DeFi apps.
- Connection between networks: Level 2 usually stays inside one network, while L3 is built to work with many networks, helping apps move and work between blockchains more easily.
- Who uses it: Level 2 is mostly used by developers focused on making blockchains faster and cheaper. Layer 3 is used by developers building apps people actually use, like games and DeFi apps, mainly those that work on more than one chain.
Why Layer 3 Matters for Web3 Builders and Investors
Instead of shared networks, Layer 3 crypto projects run on app-specific chains on top of Layer 2 and L1. This creates better performance and clearer growth paths.
From a builder’s point of view, this brings real freedom:
- Full control over fees, governance, and performance, so every chain is made around one specific app.
- Flexible setups that let teams choose how consensus, data, and system execution work, instead of following fixed rules.
- Dedicated blockspace that avoids congestion and reliance on other apps.
- Faster development and simpler upgrades when scaling.
When it comes to the user, the impact is immediate:
- Lower fees thanks to off-chain processing and simple settlement.
- Faster and easier interactions with less waiting.
- Apps that feel more reliable because they avoid shared blockspace.
- Easier cross-chain use, which lets users move across ecosystems with less friction.
For investors focused on long-term value, Layer 3 brings more clarity:
- Clearer project stories, since activity is not mixed with other apps.
- Easier ways to monitor real usage, revenue, and how tokens are actually used.
- Lower operating costs and better performance, which help long-term growth.
- Wider reach through interoperability, reducing risk and supporting stronger valuations.
How We Selected These Layer 3 Crypto Projects
When looking at Layer 3 projects, we focused on what actually matters in practice. Instead of theory, we looked at how they are set up today and how they are growing. These are the main points we considered when choosing these Level 3 solutions:
- Real activity, not just ideas: We looked at whether there are live games, dApps, users, TVL, or real integrations in the ecosystem.
- Clear Third Level setup: Each project is built on top of Layer 2, centered on the app layer, and created across multiple chains.
- Easy to build on: The best platforms let builders change fees and execution without breaking security.
- Strong community activity: Active developers, open tools, useful docs, and visible community work mattered a lot.
- Long-term vision: We focused on projects that fit long-term trends (scaling, modular design, and better Web3 user experience).
Top Layer 3 Crypto Projects to Watch
1. Arbitrum Orbit (ARB) – Tier 3 Framework for Application-Specific Chains on Arbitrum
Arbitrum Orbit is a solution that helps teams build a blockchain in their own space in the Arbitrum ecosystem. This system is built on Ethereum and the Arbitrum ecosystem and has been built using Arbitrum’s Nitro solution. With Orbit, a project can launch a chain as L2 or L3, and all transactions are finally secured by Ethereum.
In simple terms, Orbit lets projects build a blockchain made just for their app. Teams can decide how fast it is, how fees work, and how the chain is managed. This helps avoid traffic from other apps and makes development easier for games and DeFi apps.
The main risks are competition from other chain frameworks, the chance of the ecosystem becoming too divided, and uncertainty about how much benefit this creates for the ARB token in the long run. Even so, Orbit is mainly interesting for builders, infrastructure investors, and people focused on Ethereum’s future.
2. Orbs (ORBS) – Layer 3 Middleware for Advanced Execution and Cross-Chain Logic
Orbs works with big blockchains like Ethereum, Polygon, and BNB Chain. It adds features (automation, better logic, cross-chain actions, and more) without forcing apps to change networks.
The platform uses a Proof-of-Stake model and makes it easier to run more precise tasks. This supports developers in adding extra features to smart contracts and at the same time keeping everything working well in many ecosystems.
Orbs is useful because it helps solve limits found in basic smart contracts (especially in bigger DeFi use cases). With tools including automated trading, liquidity routing, and cross-chain execution, it helps protocols do more things, spend less money, and run more smoothly than when they use only L1s or L2s.
This makes Orbs a good option for established DeFi protocols that want extra features without rebuilding their systems from scratch. At the same time, it has challenges like depending on partnerships to grow and competing with other cross-chain solutions. Orbs mainly interests DeFi builders, infrastructure-focused investors, and teams working with advanced on-chain automation.
3. Degen (DEGEN) – Social-Native Token Powering App-Layer Experimentation
Degen began as a crypto project focused on social use. Over time, it turned into a Level 3 blockchain built on Base, which runs on the Ethereum network. The network was created to support fast and low-cost transactions and is mainly used for payments, games, NFTs, and social apps.
Instead of focusing on heavy infrastructure, Degen Chain puts more attention on social and cultural use cases. The objective is to make it easy to test new ideas, reward users, and create apps that people actually use and interact with.
Degen is important because it shows that L3 is more than just scaling. By offering low fees and high transaction speeds, developers can test faster than it would be on L1s or L2s. The high number of transactions shows that there is interest in blockchains built for users, not just for protocols.
However, DEGEN is still very speculative. Its long-term value is unclear, and adoption depends a lot on hype, trends, and how the market feels. It mainly attracts degen traders, social and gaming users, NFT communities, and short-term investors looking for momentum.
4. Xai (XAI) – Layer 3 for Web3 Gaming on Arbitrum
Xai is a Third Level blockchain built on Arbitrum Orbit and designed for Web3 games. It was created to make games run fast, with smooth gameplay. Most crypto steps (like wallets) stay in the background so players focus only on playing.
The goal of this project is to make blockchain games feel like traditional ones, where users can own items and trade them, but they do not need to know how the blockchain works.
Xai is important because games need speed and stable costs. On shared blockchains, this is hard to control. By using a network built only for games, Xai shows how Layer 3 chains can support apps made for a large number of users.
A main downside is that Xai needs real games and active players to grow, and competes with other blockchains made for gaming. Even so, Xai mainly attracts gaming investors, game studios, and people who believe in blockchains built for one main use.
5. Cartesi (CTSI) – Application-Specific Rollups With Linux-Based Execution
Cartesi is built on Ethereum and compatible L2 networks. It is made for apps that need more computing power. Developers can build dApps using common programming languages and a full Linux system. Heavy work happens off-chain, and only the final results go to the blockchain. This helps keep the network fast and light.
Cartesi exists because blockchains are not good at handling complex tasks. By using tools that developers already know, it makes building apps easier and cheaper. This also helps bring more developers into Web3.
With Cartesi, apps can do more than simple DeFi or NFTs. It becomes easier to build projects with real features and deeper logic, closer to normal software.
The downside is that Cartesi can be harder to understand at first. This can slow adoption. It also competes with other computer-focused blockchains and is less known by regular users. Cartesi mainly interests technical builders, infrastructure investors, and people who believe in long-term blockchain development.
6. Dream Machine Token (DMT) – Experimental App-Layer Token Economy
Dream Machine Token is an experimental app-layer token built on Arbitrum (inside the Ethereum ecosystem). It is used in The Dream Machine, a blockchain gaming platform that works like an online arcade. The goal is not to scale blockchain tech, but to test game rewards and how players interact with Layer 3 tokens.
DMT works like arcade coins where players can use the tokens to unlock levels, buy items, or win rewards. The token forms part of the gaming experience.
DMT is interesting because it uses Level 3 ideas to test how tokens behave inside games. The token is closely linked to gameplay, NFTs, and social features, turning the platform into a space to test game-based token systems with real users.
The downside is that DMT mostly works only inside The Dream Machine. Its success depends on fun games and players staying active. It also has less attention compared to bigger Third Level projects. DMT mainly attracts high-risk traders, experimental investors, and gaming-focused crypto users who enjoy testing new token ideas through play.
7. zkHyperchains – ZK-Based Layer 3 Chains
zkHyperchains are L3 blockchains created by zkSync and built on Ethereum. They use zero-knowledge technology and ZK rollups. With the ZK Stack, teams can create their own L2 or L3 blockchains. These chains can be shaped for specific apps and still work well with other Hyperchains and the Ethereum network.
zkHyperchains are important because they mix strong security with flexibility and speed. Transactions are grouped into ZK proofs, and those proofs can be grouped again. This helps the system handle more activity without losing security.
This setup works well for games, social apps, and financial products that need fast actions, privacy options, and easy movement of assets across chains. Teams can also choose how their data is stored and shared, based on what their apps need.
The downside is that ZK tools are hard to build with and take more time to learn. Development can be slower, and there is strong competition from other scaling solutions. zkHyperchains mainly attract infrastructure investors, developers who already work with ZK tech, protocol teams that want more control, and people who strongly believe in Ethereum in the long term.
8. Quant (QNT) – Layer 3 That Helps Blockchains Talk to Each Other
Quant exists because most blockchains work on their own and do not communicate well with each other. It connects them. Using its Overledger Network, Quant works with Ethereum and Bitcoin and lets them share data and move value between each other, without changing how they were built.
Developers work with one interface, and Quant handles the hard part behind the scenes. No need to rebuild apps for every chain or manage different rules or systems. One app can work across many blockchains at the same time.
Quant matters because companies, banks, and large platforms often use more than one network, and they need them to work together.
One limitation is that Quant is made mainly for companies, not for open communities. Its technology is also not open-source. Even so, it attracts investors and teams who care more about things working well than following quick trends.
How to Analyze Layer 3 Crypto Projects Before Investing
Not every project that calls itself a “Layer 3” is really an L3. The term is popular now, so many teams use it as a marketing trick. To avoid poor investment choices, pay attention to these basic points:
- Check if the project is truly Third Level: A real one runs on top of a Level 2 and adds something extra, like custom logic or features made for a specific app. If it looks the same as an L2 or just another sidechain, the “L3” name may be only marketing.
- Look at the Layer 1 and Layer 2 behind it: If the L1 or L2 is weak, has security issues, or few users, the L3 will have problems too.
- See if there are real use cases: Are there real apps using it? Are people actually active on the network? Real products and active teams matter much more than future promises.
- Understand what the token really does: Is the token used to pay fees? For staking? For voting? Or does it exist only for speculation?
- Check the team and the roadmap: A public team and good funding are positive signs.
Watch the community behavior: A strong community talks about building and improving the project. If the focus is only on price, that is a warning sign.
Quick warning: In crypto, solid projects take time to grow. The best Layer 3 crypto projects are built on real tech, real users, and real value, not just big words.
What Layer 3 Means for Web3 Marketing and Growth
Layer 3 changes how Web3 products are built and how people use them. For investors, this also makes it easier to see which projects have real use and can last over time.
Despite this, L3 may be complex, so clear explanations are important. Many teams focus on building the product first and forget to clearly explain what they are creating. When people do not understand the product, they ignore it, even if the tech is good, and when things are explained simply, people can understand the value more easily.
That is why many Third Level projects seek support with:
- Explaining the product in really simple words
- Reaching the right people and getting attention
- Working with influencers who already talk to crypto users
- Sharing ideas and updates in a clear way
- Getting mentioned in crypto media people trust
