Top 10 Layer 2 Blockchain Crypto Coins


Layer 2, also known as L2, encompasses any off-chain network, system, or technology constructed atop a blockchain, typically referred to as a layer-1 network. Its primary purpose is to enhance the functionalities of the underlying base-layer network. Layer-2 networks play a crucial role in supporting blockchains by introducing improvements like increased transaction throughputs. The commonly employed layer-2 solutions include state channels, sidechains, optimistic roll-ups, and zero-knowledge roll-ups.

While layer 1 prioritizes decentralization and security, the escalating popularity of the network has led to its current capacity of slightly over 1.5 million daily transactions. Moreover, layer-1 networks, with their ability to process approximately 15 transactions per second, often encounter congestion during periods of heightened network activity.

To address these challenges, layer-2 blockchain solutions act as an extension of layer-1 blockchains, forming a separate blockchain above the layer-1 network. Layer 2 solutions facilitate communication and alleviate the transaction load on the mainnet through smart contracts that leverage and benefit from the robust decentralized security model of Layer 1. In essence, layer 1 manages security, data availability, and decentralization, while layer-2 solutions handle scalability related to transactions. This article will outline 10 notable layer-2 crypto projects worth your attention.

zkSync (ZKS) 

It operates as a Layer-2 protocol employing zero-knowledge rollup (ZK-rollup) technology to scale Ethereum. The primary objective is to enhance Ethereum’s transaction throughput while upholding its foundational principles of freedom, self-sovereignty, and decentralization on a larger scale.

 zkSync is a trustless protocol designed for scalable and cost-effective payments on the Ethereum network, utilizing zkRollup technology. It relies on zero-knowledge proofs and on-chain data availability to maintain the security of users’ funds, making them as secure as if they were still on the mainnet. Additionally, zkSync boasts an ecosystem of decentralized applications (DApps), including Curve (a stablecoin exchange), Yearn Finance (a yield optimizer), and Taker Protocol (DAO-based).


It stands out as the first modular Layer-2 (L2) solution with a primary focus on achieving widespread adoption and decentralized governance. Its governance relies on the native token, MNT, enabling voting on all decisions related to new initiatives within the network. Mantle’s unique feature includes a modular structure designed to accommodate various transactions and actions across different layers, managed by network participants through Ethereum rollups. 

Rollups efficiently move both computation and staged storage off-chain, leading to a reduced computational load sent and processed on Layer 1. Despite its launch in July 2023, the project has remarkably achieved a total market capitalization of $1.7 billion, with 52% of its tokens currently in circulation.


It was established in 2017, operates as a scalable Layer-2 (L2) blockchain with a primary focus on delivering secure and low-cost transactions.
