Top Ethereum Layer 2 Projects in 2023: Scaling Solutions for ETH:

Last Updated on March 19, 2024 by Ameer Hamza

Layer 2 protocols in the Ethereum ecosystem serve as remedies for the scalability challenges the primary Ethereum blockchain faces. Due to their close ties to Ethereum’s Layer 1 blockchain, these Layer 2 solutions are able to perform blockchain transactions and then transmit them to the main chain for validation.

In essence, Layer 2 serves as a relief valve, redirecting and processing part of the traffic away from the main network when the Ethereum network becomes congested due to a spike in user activity. By reducing the congestion, this improves the performance of the entire network. The Layer 2 protocols allow Ethereum’s original chain to surpass its daily transaction cap of one million by speeding up transaction processing without sacrificing decentralization or security. In addition, these protocols have a number of benefits, such as lowering gas costs and enabling developers to create new applications that give customers a better and more effective experience. Below are some of the top scaling solutions for ETH.

2023’s Top Scaling Solutions For ETH


One of the most renowned Layer 2 scaling solutions for ETH is Polygon, which provides a solid foundation for processing transactions across a wide range of applications. These include trading platforms and blockchain-based games.


  • Cost-Effective and Swift: Polygon provides a fast and affordable blockchain network that supports a variety of use cases, making it an appealing option for both users and developers.
  • Large User Base: Polygon has amassed a sizable and active user community, highlighting its popularity and usefulness, with over 400,000 daily active users.
  • Polygon enjoys the advantages of significant backing from prominent companies like Coinbase Ventures, which adds legitimacy and resources to its expansion and development.


  • Polygon’s proof-of-stake (PoS)–based consensus process has come under fire for being seen as excessively centralized. This argument casts doubt on the network’s decentralization and security.
  • Layer 2 solutions like Polygon provide improved scalability and efficiency but are typically less safe than the main Ethereum blockchain. This difference must be considered, especially for applications that demand high security.


In the Ethereum ecosystem, one of the most notable scaling solutions is Arbitrum, a popular rollup-based Layer 2 solution. The Arbitrum airdrop event in March 2023 distributed free ARB tokens to users’ wallets and significantly increased their value.


  • Large User Base: Arbitrum has a sizable user base of more than 3.9 million users, demonstrating the app’s widespread use and usefulness.
  • Diverse Ecosystem: The platform supports a wide-ranging ecosystem that includes NFT marketplaces, blockchain games, stablecoins, and several other applications.
  • DeFi Integration: A number of the most well-known DeFi applications, including 1inch, Aave, Balancer, and others, have endorsed Arbitrum. This integration enhances its credibility and functionality within the DeFi space.


  • Since Arbitrum is not a stand-alone chain, its operation depends on the safety of the Ethereum chain that it is based on.
  • Due to Arbitrum’s optimistic roll-up technology, withdrawals of funds can take up to a week.


Polygon and Arbitrum are Ethereum Layer 2 scaling solutions critical to tackling the Ethereum network’s scalability issues. They provide increased speed and cost, attracting large user bases and backing from important players in the blockchain field. In the ever-changing blockchain ecosystem, these Layer 2 projects enhance Ethereum’s capabilities and boost the overall user experience.
