3. Polygon (MATIC) – Most Versatile Scaling Solution
Polygon offers a multi-faceted approach to Ethereum scaling. Its solutions include Polygon PoS, zkEVM, and Polygon Miden, catering to diverse developer needs. The recently introduced Polygon 2.0 upgrade features the POL token, which supports staking and governance across multiple chains.
This flexibility and wide array of tools make Polygon a top choice for developers building scalable applications on Ethereum.
4. Optimism (OP) – Best for EVM Equivalence
Optimism is renowned for its EVM equivalence, ensuring full compatibility with Ethereum smart contracts and dApps. It uses optimistic rollups to process transactions off-chain, posting only results to the mainnet. This maintains high throughput and leverages Ethereum’s security.
The OP token is used for governance and incentives, supporting a decentralized and community-driven ecosystem. Continuous upgrades keep Optimism competitive among L2 solutions.
5. Blast (BLAST) – Most Innovative Yield-Generating L2
Blast stands out with its native yield generation for ETH and stablecoins. By integrating with Ethereum staking and Treasury Bill protocols, it allows users to earn passive income seamlessly. The platform uses optimistic rollup technology and offers a gas revenue-sharing model for dApp developers.
Shortly after launch, Blast surpassed $500 million in TVL, demonstrating strong market interest. Its innovative approach makes it a notable project in the L2 space.
6. Loopring (LRC) – Best for Building DEXs
Loopring is a protocol-agnostic platform specializing in decentralized exchanges (DEXs). It uses zero-knowledge rollups to process trades off-chain while settling on-chain, combining the efficiency of centralized exchanges with decentralized security.
The LRC token is used for staking, governance, and fee discounts, making it integral to the network. It remains a popular choice for developers creating secure and scalable trading platforms.
7. Eclipse – Best for Transaction Speed
Eclipse is designed for speed, utilizing the Solana Virtual Machine (SVM) for execution to achieve high throughput with low latency. It settles on Ethereum and uses Celestia for data availability, blending Solana’s performance with Ethereum’s security.
The platform uses RISC Zero for zero-knowledge fraud proofs and relies on ETH for gas fees, simplifying integration with Ethereum-based DeFi and NFTs.
8. Mantle (MNT) – Best for Decentralization
Mantle emphasizes decentralization through a modular architecture and DAO governance. By separating execution, data availability, and finality, it achieves flexibility and robust decentralization.
The merger with BitDAO has strengthened its ecosystem, and the MNT token enables community-led governance, making it appealing to users who prioritize decentralization.
9. Immutable X (IMX) – Best for NFTs and Gaming
Immutable X is the leading L2 for NFTs and blockchain gaming, offering gas-free minting and instant transactions. Built on StarkWare’s ZK-rollup technology, it supports high-volume NFT trading without compromising security.
The platform is carbon-neutral and offers easy API integration. The IMX token is used for staking, governance, and fees, enhancing its utility.

What Are Ethereum Layer 2 Projects?
Ethereum Layer 2 projects are scaling solutions built on top of the Ethereum mainnet (Layer 1). They process transactions off-chain to alleviate congestion, reduce fees, and increase throughput, while still benefiting from Ethereum’s security by finalizing transactions on the mainnet.
Types of Ethereum Layer 2 Solutions
Several architectural approaches are used in L2 scaling:
Rollups: These bundle multiple transactions off-chain and submit compressed data to Ethereum. There are two types:
- Optimistic Rollups: Assume transactions are valid and use fraud proofs for disputes. Examples: Arbitrum, Optimism.
- zkRollups: Use zero-knowledge proofs for validation, ensuring privacy and security. Examples: zkSync, StarkNet.
- Sidechains: Independent blockchains that run parallel to Ethereum and use bridges for interoperability. Example: Polygon PoS.
- State Channels: Enable off-chain transactions between parties, with only the final state recorded on-chain. Ideal for microtransactions.
- Plasma Chains: Child chains that handle transactions off-chain and periodically commit to Ethereum. Less common today.
- Validiums: Use zero-knowledge proofs for validation but keep data off-chain, offering high scalability with reduced fees.
Why Consider Investing in Ethereum Layer 2 Projects?
Layer 2 solutions present compelling investment opportunities for several reasons:
- Scalability: They significantly enhance Ethereum’s transaction capacity, supporting broader adoption.
- Cost Reduction: By moving transactions off-chain, L2s drastically reduce gas fees.
- Growing Adoption: As Ethereum usage grows, so does the need for L2 solutions, driving demand and value.
- Innovation: Continuous technological advancements keep L2s at the forefront of blockchain evolution.
- Potential Returns: Many L2 tokens have lower market caps compared to Ethereum, offering significant growth potential.
