The decentralized finance (DeFi) landscape continues to evolve rapidly, with Layer 2 (L2) blockchain solutions playing a pivotal role in enhancing scalability, reducing transaction fees, and improving user experience across Ethereum and other base networks. As more users and developers migrate to L2 platforms for faster and cheaper transactions, the native tokens powering these ecosystems have gained significant market traction.
Below is a comprehensive overview of the largest Layer 2 DeFi tokens by market capitalization, highlighting key projects shaping the future of scalable blockchain infrastructure.
What Are Layer 2 Tokens?
Layer 2 tokens are cryptocurrencies that power secondary protocols built on top of existing blockchains—most commonly Ethereum. These solutions aim to alleviate congestion on the main chain by processing transactions off-chain or in parallel, then settling final results back on the primary network.
These tokens often serve multiple purposes:
- Governance: Allowing holders to vote on protocol upgrades.
- Staking: Securing the network and earning rewards.
- Utility: Paying for gas fees, accessing services, or incentivizing ecosystem growth.
With rising demand for scalable DeFi applications, L2 tokens have become critical components of the Web3 economy.
Leading Layer 2 DeFi Tokens by Market Cap
Mantle (MNT)
With a market cap exceeding $77 billion, Mantle ranks as one of the most valuable Layer 2 ecosystems. Built around modular blockchain architecture, Mantle combines an Ethereum Layer 2 rollup with a decentralized autonomous organization (DAO)-governed treasury. Its native token, MNT, enables governance participation and staking incentives.
Recent data shows strong price momentum, with a 4.92% gain over seven days and healthy trading volume surpassing $10 billion in the last 24 hours.

Polygon (POL) – Formerly MATIC
Polygon rebranded its token from MATIC to POL as part of its transition into a multi-chain ecosystem powered by EigenLayer’s restaking technology. Now known as the Polygon Ecosystem Token, POL supports a suite of zk-powered rollups and interoperable chains.
Boasting a market cap near $75 billion, POL has maintained steady growth despite broader market fluctuations. Its 24-hour trading volume remains robust at over $4.3 billion, reflecting sustained institutional and retail interest.
Arbitrum (ARB)
Arbitrum stands out as a leader among optimistic rollups, offering high-speed, low-cost transactions while maintaining Ethereum’s security. The ARB token fuels governance within the Arbitrum DAO and has seen impressive adoption across major DeFi platforms like Uniswap and Aave.
With a market cap of approximately $67.7 billion and a weekly return of 10.80%, Arbitrum continues to lead in both developer activity and total value locked (TVL).
Optimism (OP)
Optimism leverages optimistic rollup technology to scale Ethereum efficiently. The OP token drives decentralized governance and ecosystem incentives through the Optimism Collective—a dual-house governance model focused on public goods funding.
Despite moderate price movements (1.40% weekly gain), Optimism maintains a solid position with a $37.9 billion market cap and strong integration with top-tier dApps.
Immutable (IMX)
Focused on Web3 gaming and NFTs, Immutable X uses zk-rollup technology to enable gas-free minting and instant trading. Its native token, IMX, is used for staking, governance, and paying protocol fees.
With a market cap above $32 billion and consistent weekly gains, Immutable is well-positioned to capture growing demand for blockchain-based gaming economies.
Stacks (STX)
Though not an Ethereum L2, Stacks brings smart contracts and DeFi capabilities to Bitcoin via a unique consensus mechanism called Proof of Transfer (PoX). STX serves as the utility token for securing the network and launching decentralized apps on Bitcoin.
Its $40 billion valuation reflects increasing interest in Bitcoin-centric DeFi innovations.
Starknet (STRK)
Built by StarkWare, Starknet is a permissionless ZK-Rollup platform enabling scalable smart contracts using STARK proofs. The STRK token plays a crucial role in network security through token-based economic models and governance.
With over $16 billion in market value, Starknet continues to attract developers building privacy-preserving and high-throughput applications.
Emerging Contenders in the L2 Space
While the above projects dominate current rankings, several emerging Layer 2 tokens show strong potential:
- ZKsync (ZK): Gaining momentum with its zkEVM compatibility and growing NFT marketplace support.
- Movement (MOVE): A rising star leveraging MoveVM for secure, efficient smart contract execution.
- Astar (ASTR): Focused on multi-chain interoperability within the Polkadot ecosystem.
- Fuel Network (FUEL): Designed as a modular execution layer optimized for speed and developer flexibility.
These tokens may not yet rank among the top by market cap but are rapidly gaining developer mindshare and user adoption.
Frequently Asked Questions (FAQ)
Q: What makes a token "Layer 2"?
A: A Layer 2 token belongs to a blockchain protocol built atop another network (like Ethereum) to improve scalability and reduce costs. These tokens typically support governance, staking, or transaction fees within their respective ecosystems.
Q: Why invest in Layer 2 DeFi tokens?
A: L2 solutions address key limitations of base blockchains—high fees and slow speeds. As DeFi usage grows, so does demand for efficient networks, increasing utility and value accrual for their native tokens.
Q: Is Arbitrum better than Optimism?
A: Both use rollup technology but differ technically—Arbitrum uses optimistic rollups with multi-round fraud proofs, while Optimism employs single-round proof systems. The "better" choice depends on use case: Arbitrum often leads in TVL; Optimism excels in ecosystem funding initiatives.
Q: How does Polygon differ after its rebrand to POL?
A: Polygon shifted from a single-chain sidechain model to becoming an “aggregator” of multiple zk-rollups using restaking. This evolution positions POL as a meta-layer securing various independent chains under one economic umbrella.
Q: Can Bitcoin support Layer 2 DeFi?
A: Yes—projects like Stacks (STX) bring smart contracts to Bitcoin, enabling lending, borrowing, and trading without altering Bitcoin’s base protocol.

Key Trends Driving Layer 2 Adoption
- ZK-Rollup Dominance: Zero-knowledge proof technologies are gaining favor due to faster finality and stronger security guarantees.
- Modular Architecture: Chains like Mantle and Fuel emphasize modularity—separating execution, consensus, and data availability layers for greater efficiency.
- DAO Governance Expansion: Most L2s now operate as DAOs, giving token holders direct influence over funding and development priorities.
- Interoperability Focus: Cross-chain bridges and messaging protocols are becoming standard features in L2 design.
Final Thoughts
As Ethereum continues to scale through Layer 2 innovation, these tokens represent more than just speculative assets—they’re foundational pieces of a decentralized digital economy. From zk-rollups to optimistic scaling solutions, each project contributes uniquely to solving blockchain’s trilemma: scalability, security, and decentralization.
Whether you're an investor, developer, or DeFi enthusiast, understanding the dynamics of leading L2 ecosystems is essential for navigating the future of finance.
