Blockchain adoption is growing rapidly, but scalability, high gas fees, and network congestion continue to slow mainstream usage. Layer-2 solutions (L2) are the most promising technologies that solve these issues by processing transactions off-chain while remaining secured by the underlying Layer-1 network.
In 2025–2026, Layer-2 ecosystems are expected to dominate Web3, gaming, DeFi, and real-world asset tokenization. Some L2 projects are already getting attention, while many powerful and innovative options still remain underrated.
Here are the Top 10 Underrated Layer-2 Crypto Projects that have the potential to explode in 2026 👇
zkSync (ZKS)
Technology: Zero-Knowledge Rollups
Why It’s Underrated: zkSync aims to deliver high-speed transactions with ultra-low fees while ensuring security equivalent to Ethereum. With strong backing from major investors and increasing ecosystem adoption, zkSync could become one of the dominant ZK scaling solutions.
Key Growth Drivers
Massive developer ecosystem and zkEVM compatibility
Active real-world application deployment
Strong partnership expansion
Arbitrum Orbit (ARB)
Technology: Optimistic Rollup + modular L2 chains
Why It’s Underrated: While Arbitrum is popular, Arbitrum Orbit, a framework that allows launching custom L2s and L3s, is under-recognized. It can become the foundation layer for thousands of consumer-facing L2 networks.
Starknet (STRK)
Technology: zk-STARK rollups
Why It’s Underrated: Designed for true scalability with mathematically secure proof systems, Starknet offers advanced performance ideal for gaming and high-frequency finance.
Mantle (MNT)
Technology: Modular L2 powered by EigenLayer
Why It’s Underrated: Mantle integrates modular data availability and staking systems, reducing costs significantly. With backing from BitDAO, Mantle has strong liquidity and real adoption potential.
Optimism Superchain (OP)
Technology: Optimistic Rollup & inter-connected L2 ecosystem
Why It’s Underrated: Optimism aims to connect many chains into one unified superchain. Backed by Coinbase’s Base network, it has massive growth potential for onboarding millions of users.
Linea (LINEA)
Technology: zkEVM by Consensys
Why It’s Underrated: Created by the company behind MetaMask and Infura, Linea has institutional advantages and will play a major role in onboarding Web2 users into crypto.
Base (BASE)
Technology: Optimism stack L2 built by Coinbase
Why It’s Underrated: Base focuses on real-world applications and retail onboarding. Its ecosystem growth rate is one of the fastest among L2 solutions.
Manta Network (MANTA)
Technology: zk-Proof modular scaling
Why It’s Underrated: Strong real-life applications across identity, AI, and privacy, with bridges between ecosystems.
Scroll (SCROLL)
Technology: zkEVM scaling
Why It’s Underrated: Scroll emphasizes decentralization and developer experience, building the most Ethereum-friendly zkEVM solution.
Metis (METIS)
Technology: Hybrid optimistic rollup
Why It’s Underrated: Brings decentralized autonomous company (DAC) model, enabling scalable Web3 business operations and enterprise adoption.
Why Layer-2 Projects Could Explode by 2026
| Reason | Impact |
|---|
| Mass institutional adoption | Billions entering crypto markets |
