List of the Top 3 Layer 2 Protocols for OnFinality in 2025

Polkadot represents a groundbreaking blockchain network tailored for the Web 3.0 vision, which seeks to establish a decentralized and fair internet where users maintain control over their personal data, thereby cultivating vibrant markets through improved network efficiency and robust security. Founded in 2016 by Gavin Wood, a former Co-Founder and CTO of Ethereum, Polkadot tackles significant obstacles that have previously slowed the broader adoption of blockchain technology. Its development framework, Substrate, created by Parity Technologies, is designed to simplify the creation of customized blockchains that cater to individual developer requirements. Furthermore, Polkadot promotes interoperability among different blockchains, ensuring that upgrades occur effortlessly, and implements a "shared security" model that enables developers to focus on technological advancements rather than allocating resources to manage a new blockchain's operational team. This innovative strategy not only accelerates the development process but also strengthens the entire blockchain ecosystem, fostering collaboration and innovation across various platforms. In this way, Polkadot is not just a technological solution, but a catalyst for a new era of interconnected blockchain applications.

Astar Network acts as a strong and versatile foundation specifically designed for applications within the realm of Web3.0. Built on Parity’s Substrate framework, it has the capability to transition into a Polkadot parachain while also serving as a proficient smart contract platform. A noteworthy aspect is that the Polkadot Relaychain is purposefully constructed without smart contract support, allowing Astar to fill this gap effectively. For developers focused on decentralized applications (dApps), scalability is a primary concern, enabling the creation of a wide variety of applications on Astar Network without the lingering worry of scalability issues. As an open-source project, Astar Network offers countless opportunities for individuals to engage with its ecosystem, inviting contributions from anyone keen on enhancing its features. The goal of Astar Network is to provide a decentralized application platform that is not only scalable and interoperable but also plays a crucial role in shaping the forthcoming landscape of the internet, referred to as Web3.0. Through its community-driven approach, the initiative cultivates an environment rich in innovation and collaboration, fostering a vibrant network of developers and users who are eager to explore new possibilities together. This collaborative spirit ensures that Astar Network remains at the forefront of technological advancements in the decentralized space.

Ava Protocol is an innovative Actively Validated Service (AVS) designed on EigenLayer, aimed at enabling seamless autonomous transactions across Ethereum and other blockchain platforms. It provides developers with a suite of tools to enhance cryptocurrency transactions through smart automation, superior privacy measures, straightforward integration, and significant cost savings. One of its most impressive features is intelligent automation, which facilitates automatic transaction execution when predefined conditions are satisfied, complemented by advanced Maximal Extractable Value (MEV) protection that safeguards against front-running and privacy infringements. Additionally, the protocol encourages composability, allowing developers to effortlessly combine smart contract calls without extensive programming, while offering remarkable reductions in gas fees, potentially reaching up to 90%. Ava Protocol also boasts a sophisticated technology framework, featuring a customizable Studio for developing automated strategies, a robust SDK for ensuring private transactions, and the EigenLayer AVS network supported by restaked ETH. This comprehensive ecosystem delivers a complete solution for developers focused on optimizing their blockchain applications. Overall, Ava Protocol's multi-dimensional strategy positions it as a pivotal entity in the rapidly changing decentralized finance landscape, ensuring that developers can innovate with confidence and efficiency.
