Best Layer 2 Protocols

Compare the Top Layer 2 Protocols as of October 2025

What are Layer 2 Protocols?

Layer 2 protocols are blockchain protocols that are built on top of an existing blockchain network. A layer 2 protocol is designed to improve the scaling problems and transaction speeds and fees that layer 1 blockchain networks and protocols face. Decentralized applications can be built on Layer 2 protocols, and layer 2 protocols interact with layer 1 protocols in order to improve efficiency and overall user experience. Compare and read user reviews of the best Layer 2 Protocols currently available using the table below. This list is updated regularly.

    Meter

    Meter

    Decentralized Finance Labs

    Meter is a high performance infrastructure that allows smart contracts to scale and travel seamlessly through heterogeneous blockchain networks. Meter is a Layer 1 and Layer 2 blockchain protocol. The Meter system consists of two tokens: MTRG, the governance token (eMTRG is the ERC20 version), and MTR, the low-volatility currency token. Financial assets should flow freely among blockchains. Meter’s HotStuff-based consensus allows 1000s of validator nodes, making Meter the most decentralized Layer 2 for Ethereum. Meter processes thousands of transactions per second and transactions are confirmed almost instantly. Meter Passport allows assets and smart contracts travel and communicate across heterogeneous blockchains for the best price, liquidity and yield. Meter is an Ethereum Compatible with unique enhancements. Unlike other Layer 2, DEXes build on Meter are front running/MEV resistant, fast and uncensorable.

    Polkadot

    Polkadot

    Polkadot

    Polkadot is a blockchain network being built to enable Web 3.0, a decentralized and fair internet where users control their own data and markets prosper from network efficiency and security. Polkadot was founded in 2016 by Gavin Wood, former Co-Founder and CTO of Ethereum. Polkadot’s technology addresses the major issues that have stymied blockchain adoption in recent years. Polkadot’s software development toolkit, Substrate, created by Parity Technologies, makes it easy for blockchain developers to build their own custom, fit-for-use blockchains. Polkadot also enables multiple blockchains to communicate between each other, allows for easy upgradeability, and introduces “shared security”, a plug-and-play network security model that allows developers to focus on the technology and avoid spending time and resources recruiting a set of operators to run a new blockchain.

    Nervos

    Nervos

    Nervos

    Early internet applications lived on segregated networks needing different ways to access and interact. Now, in today’s decentralized world we again see this segregation into different ecosystems with poor interoperability. The Nervos Network solves for this problem by offering a suite of integrated solutions that allow the developer to build Universal Apps. Choose your interface, choose your crypto and stick with it, but still access the entire space. The frustration of multiple wallets, exchanges and seed phrases is no more with Nervos. Build on Nervos and have the ability to target any Virtual Machine (VM). Port your dApp across with ease and instantly have access to the entire blockchain ecosystem. Sustainable crypto-economics with a built-in store of value mechanism to solve some of the biggest sustainability challenges for public blockchains.
