As the Ethereum network experienced increasing utilization, its inherent limitations began to surface, including slow transaction speeds, frequent congestion, and expensive gas fees. To address these challenges, Layer 2 has emerged, seeking to enhance Ethereum’s scalability and overall performance. Let’s explore the top Layer 2 crypto projects with Coincu in this article.
What are Layer 2 crypto projects?
Layer 2 crypto projects, as they are commonly referred to in the cryptocurrency community, represent a collection of projects and technologies designed to mitigate Ethereum’s scalability issues while preserving its robust security features.
One of the standout characteristics of Layer 2 crypto projects is their integration with the Layer 1 blockchain, Ethereum itself. This strategic alignment allows Layer 2 platforms to inherit Ethereum’s formidable security measures while significantly improving transaction speed and reducing costs.
By the end of 2021, Ethereum boasted nearly 4,000 decentralized applications (dApps), underscoring its position as a blockchain powerhouse. Nevertheless, the growing demand for Ethereum’s services revealed the network’s shortcomings. Slow transaction speeds made conducting business on the blockchain laborious, frequent congestion led to frustrating delays, and soaring gas fees imposed substantial financial burdens on users.
In response to these challenges, a multitude of Layer 2 crypto projects emerged, providing a diverse range of strategies to boost Ethereum’s efficiency. These solutions employ various techniques, including sidechains, state channels, and rollups, to offload transactions from the main Ethereum network.
By doing so, Layer 2 crypto projects can process transactions at a faster rate and significantly reduce the associated fees, making decentralized applications more accessible and cost-effective for users.

This user-centric approach aims to simplify interactions with blockchain technology, making it more accessible to a broader audience.
A Growing Ecosystem
zkSync Era has garnered substantial interest from the blockchain community, with over 200 projects, including industry giants like Chainlink, SushiSwap, Uniswap, Aave, Argent, 1inch, Gnosis, and Curve, expressing their intent to deploy on the platform. This collective effort represents a significant step forward in pushing the boundaries of what is possible in the world of decentralized applications.
Highilights
zkSync is the first Layer 2 zkEVM built on the Ethereum Mainnet network, which offers significantly faster speeds compared to other Layer 2 crypto projects using Optimistic Rollup technology.
The zkSync Era ecosystem is currently one of the fastest-growing ecosystems, with a TVL reaching over $700 million in just half a year. Currently, zkSync Era has nearly 5 million wallet addresses with over 30.58 million transactions. This is a significant number of users for a blockchain that has been on the mainnet for only 6 months.
Arbitrum
Arbitrum is a layer 2 solution built to enhance the capabilities of Ethereum smart contracts, increasing their speed and scalability while adding additional privacy features.
Mission and vision
Arbitrum was created with Ethereum compatibility as a top priority, so the experience is almost identical to using Ethereum, with the important exception of being much faster and cheaper.
Highilights
Arbitrum currently ranks as the number-one largest compilation in terms of total value locked, with a growing number of prominent DeFi protocols deployed on the network.
The project provides an extension solution within the Rollup model. The main difference of Arbitrum lies in the operation of Fraud Proofs.
When challenged validators believe another validator has improperly or illegally put together an incoming batch of transactions into the following block, they submit fraud evidence.
Arbitrum also utilizes a multi-round rollup protocol to address disputes, where it will break down the dispute into smaller ones until it becomes a very small dispute, and then resolve it on-chain.
Optimism
Optimism is an extension solution on Ethereum aimed at reducing gas fees and increasing transaction completion speed, thereby providing a smoother experience for users while still maintaining security from the original Ethereum chain. Optimism belongs to the Optimistic Rollup field, utilizing the fraud-proof security mechanism.
In simple terms, user transactions are considered valid and approved if they cannot be proven fraudulent.
Mission and vision
OP Mainnet, a blockchain network with a unique vision, goes beyond traditional blockchain functions. It stands as an experiment in sustainable ecosystem funding, driven by protocol-generated revenue. At its core, OP Mainnet embraces the concept of Retroactive Public Goods Funding, a straightforward and innovative approach: if you contribute to the public good, you become eligible to receive a grant.
Highilights
- Transaction experience: With fast processing speed, the gas fee is currently reduced by 88 times compared to gas on the current Ethereum.
- Convenient for scalability and deployment of DApps: Fully supports EVM, Ethereum DApps, or dApps in compatible EVM ecosystems and can be run on layer 2 with just a few lines of code.
- Security: Optimism inherits the strict security level of Layer 1 Ethereum.
