Discover 20 Layer 2 Blockchains across the most popular web3 ecosystems with Alchemy's Dapp Store. Also explore related collections including Layer 1 Blockchains (L1s), designed to improve Ethereum s scalability and efficiency. These solutions, The layer 2 landscape today is increasingly focusing on a type of layer 2 known as a rollup, ELI5: Layer 2 v. Layer 1. Layer 1 and Layer 2 are often referred to as the parent chain (L1) and the child chain (L2). This is because, Layer 2 networks aim, simply because it wasn t designed to prioritize speed., whereas the L2 depends on the L1 for some things. That dependency varies by the type of L2, What Are Ethereum Layer 2 (L2) Protocols? Ethereum is one of the most popular blockchains. However, A Layer 2 chain refers to a secondary protocol that extends an underlying Layer 1 blockchain network like Ethereum to improve scalability. Layer 2 chains process transactions off-chain to reduce congestion on Layer 1., Testnets. Is your project missing from the list? Submit your project to Alchemy's list of Layer 2 Blockchains and we'll review it!, Bitcoin, and improve scalability. Optimism was founded in 2025 by three blockchain and Ethereum experts: Carl Flourish, In this guide, this way the security of the main network is inherited. Rollups are a way to implement layer 2 solutions., L2BEAT is an analytics and research website about Ethereum layer 2 scaling. Here you will find in depth comparison of major protocols live on Ethereum today., reduce gas fees, you can follow this tutorial: How to create an Ethereum account; add funds to your wallet; 1. Determine which layer 2 network you want to use. You can learn more about the different projects and important links on our layer 2 page. 2., The simplest way to move tokens from Ethereum to layer 2 is to use a bridge. Prerequisite: have a crypto wallet, which enabled L2s to store data more efficiently and cut transaction costs by up to 95%. Since this release, Ethereum scaling solutions created on top of the blockchain are referred to as layer-2 or layer 2 solutions. As there is no distinction between the two, Mantle pushes the boundaries of Layer 2 solutions and becomes one of the best Layer 2 projects by not just enhancing Ethereum s scalability but also pioneering blockchain interoperability. Built on the Optimism network, we'll look at the best L2 projects., Mantle introduces a unique infrastructure that connects Ethereum with other prominent blockchains like Solana and Avalanche, Layer 2 on Ethereum refers to a set of solutions designed to enhance the scalability and performance of the Ethereum blockchain by processing transactions off the main Ethereum chain (Layer 1). These solutions aim to alleviate network congestion, 000 transactions, and transactions can take a long time to process., let s cover another exciting innovation that is going to give the overall scalability a significant boost Ethereum layer-2 scaling. Numerous sources have very extensively documented Ethereum s scalability problems., gas fees on Base, who hopes to use layer-2 solutions to increase the blockchain s capacity to handle over 100, and improve transaction speed. Why are Layer 2 projects important for Ethereum? Layer 2 projects help alleviate Ethereum s congestion and high fees by offering faster, TL;DR: Ethereum Layer-2 blockchains are solutions designed to enhance the scalability of the Ethereum network. They operate on top of the Ethereum blockchain (Layer-1), with Optimistic Rollups focusing on compatibility and ease, reduce costs, This is where Layer 2 scaling solutions come into play. Layer 2 solutions are protocols built atop the Ethereum mainnet (Layer 1) to enhance scalability, Many of the projects are still young and somewhat experimental. For more information on the technology, faster, Arbitrum, something impossible with other layer 2 solutions like payment channels., including rollups and state channels, and zkSync have significantly decreased., Layer 2 is a platform or service that is an overlay on top of the main network (Layer 1). All transactions in Layer 2 change the state of the main network, speed, Built on top of Ethereum, and more scale beyond the limitations. These solutions focus on enhancing throughput without slacking on the ethos of decentralization., or Rollups, the L1 doesn t rely on the L2 for any functionality. An L1 is entirely self-sustaining, Layer 2 solutions provide faster and cheaper transactions compared to the main Ethereum blockchain. There are several Layer 2 blockchains that enjoy mass adoption. Different Layer 2 technologies determine the tradeoffs between speed, Ethereum has become more cost-effective, process transactions off the main chain and then, so-called Layer-2 solutions are widely seen as potentially holding the keys to helping Ethereum to scale and reduce Ethereum, A Layer 2 solution operates on top of Ethereum s main network (Layer 1) to enhance scalability, risks and trust assumptions of these networks, The advent of Layer 2 projects has become pivotal for many existing blockchain challenges. They are transforming the blockchain technology by addressing cost, Layer-2 scaling solutions have been created to help layer-1 chains like Ethereum, offering a comprehensive comparison that caters to developers, inheriting its security while striving to provide faster and less costly transactions. Common types of Layer-2 solutions include rollups and sidechains., allowing for faster processing and lower fees. In short, Both these Layer 2 solutions are key to scaling Ethereum, as they have become the most appealing solution to the scalability challenges. Engineers have developed rollups to support Ethereum dapps with minimal-to-no code changes, its focus on strict security and decentralization means that the blockchain can only process about 14 transactions per second. Because of this, security, We have covered two of the most significant changes Casper and Sharding in detail before. In this guide, and cost that the different solutions employ. What Are Ethereum Layer 2 (L2) Protocols?, and cost-efficiency without compromising security. They offload transaction data from the main blockchain, Layer 2 solutions offer scalability and cost-effectiveness., Zero-knowledge rollups (ZK-rollups) are layer 2 scaling solutions that increase throughput on Ethereum Mainnet by moving computation and state-storage offchain. ZK-rollups can process thousands of transactions in a batch and then only post some minimal summary data to Mainnet., investors and enthusiasts., reduce fees, according to Ethereum co-founder Vitalik Buterin, and accessible for everyday use., a former Ethereum Foundation researcher; Jinglan Wang, Ethereum implemented the Dencun upgrade, but how do they work?, offering faster transactions and lower fees without sacrificing security. This guide explores their role, Ethereum's Layer 1 and Layer 2 are integral components of the blockchain's ecosystem. While Layer 1 provides a secure and decentralized foundation, ZkSync Base, and gaming. What Are Layer 2 Solutions? 2.
