List of the Top 6 Layer 2 Protocols for Aboard Exchange in 2025

The latest advancements in layer 2 solutions for Ethereum dApps empower developers to leverage their preferred tools while effectively reducing the expenses associated with scaling their applications. Within this framework, an aggregator functions similarly to a node on Ethereum, allowing client software to execute remote procedure calls (RPCs) through a standardized API to interact with an Arbitrum chain. This aggregator plays a crucial role by transmitting these calls to the EthBridge and returning the results of transactions to the client, reflecting the behavior of a conventional Ethereum node. Although it's common for clients to route their transactions through an aggregator when engaging with an Arbitrum chain, this is not strictly necessary. The architecture permits an unlimited number of aggregators to be created, and there are no restrictions on who can act as an aggregator. To optimize processing efficiency, aggregators often merge several client transactions into a single submission to the Arbitrum chain. Moreover, the Arbitrum ecosystem includes a specialized Sequencer capable of organizing transactions, which leads to rapid transaction confirmations with minimal latency. This groundbreaking arrangement not only enhances overall throughput but also cultivates an adaptable environment where developers can explore and innovate without the constraints of high costs, ultimately promoting greater experimentation within the blockchain space. By providing such flexibility, layer 2 solutions are poised to significantly transform the landscape of decentralized applications.

Celer Network functions as a layer-2 scaling solution aimed at enabling fast, secure, and affordable blockchain applications on Ethereum, Polkadot, and multiple other blockchain systems, with the goal of achieving widespread usage. It was the first to introduce a Generalized State Channel Network and remains at the forefront of innovation in the layer-2 scaling landscape through its sophisticated Rollup technology. The platform has generated significant attention due to its notable applications and middleware like cBridge and Layer2.Finance, as well as various ecosystem initiatives that appeal to a wide range of users in sectors such as DeFi, blockchain interoperability, and gaming. Layer2.Finance specifically targets the two main barriers to DeFi's broader acceptance: high transaction costs and complicated user interfaces. Furthermore, cBridge functions as a flexible multi-chain network that allows for instant, affordable, and smooth value transfers across different Ethereum layer-2 networks, the Ethereum main chain, and plans to support additional layer-1 and layer-2 solutions in the future. As Celer Network continues to grow, it is committed to improving the overall user experience and expanding access to blockchain technology for an ever-wider audience, fostering a more inclusive digital economy.

StarkEx is engineered to produce validity proofs, ensuring that only authentic data from reliable computations is logged on the blockchain. Its impressive scalability is a result of the unequal distribution of tasks between the off-chain prover and the on-chain verifier. By supporting self-custodial decentralized applications (dApps) and integrating advanced anti-censorship strategies, it guarantees that users retain control over their assets at all times. Additionally, StarkEx is versatile enough to meet a diverse range of user needs and application features. Those looking to integrate with StarkEx can generally go live on the Mainnet within a few weeks, depending on the development stage of their off-chain Operator node. With validity proofs in place, state updates reach finality as soon as they are confirmed on-chain, which can occur within hours, contrasting with fraud proofs that necessitate a prolonged dispute resolution process. This heightened efficiency not only simplifies the transaction workflow but also significantly improves the overall blockchain user experience, making it more accessible for a wider range of applications. Overall, StarkEx stands out as a robust solution for developers aiming to leverage the benefits of blockchain technology while maintaining high levels of security and efficiency.

Ethereum's new scalability framework guarantees swift transactions and effective smart contract execution. Optimism functions as a Public Benefit Corporation (PBC), which is designed to generate profits while also delivering societal benefits through responsible and sustainable methodologies. This organizational model requires us to balance our shareholders' financial interests with the well-being of those affected by our decisions, adhering to a defined "public benefit charter." The primary goal of the Company is to enhance and protect fair access to public goods on the internet by developing open-source software. This charter reflects our dedication to the Ethereum community, as we work to uphold its core values by building infrastructure that supports the growth and sustainability of a public goods ecosystem. By doing so, we not only seek to advance technological progress but also to promote an inclusive atmosphere where all users can thrive. Ultimately, our efforts aim to bridge the gap between innovation and accessibility, ensuring that the benefits of technology are shared widely.

Polygon, which was previously referred to as Matic Network, is a comprehensive protocol and framework established for the development and interconnection of blockchain networks that are compatible with the Ethereum platform. Despite Ethereum being the favored choice for blockchain initiatives, it has its own set of limitations. Polygon effectively tackles these challenges by offering a straightforward method for deploying pre-configured blockchain networks with a single click, bolstered by a growing selection of modules that aid in the creation of tailored networks. Furthermore, Polygon includes an interoperability protocol that allows for the seamless transfer of messages between Ethereum and various other blockchain ecosystems, in addition to providing a modular and optional “security as a service” feature. Its adaptor modules significantly improve the interoperability of existing blockchain systems, simplifying their integration process. By combining the advantages of Ethereum with those provided by autonomous blockchains, Polygon delivers an attractive range of functionalities aimed specifically at developers. In essence, it is meticulously designed by developers to cater to the unique requirements of their peers, ensuring it aligns well with the evolving demands of the blockchain community while fostering innovation and collaboration within the space.
