List of the Top 4 Layer 2 Protocols for Rabby 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.

Mode is an innovative Layer 2 solution on Ethereum that rewards users for helping to grow its network through cutting-edge economic models. This platform is establishing a new on-chain economy that rewards individuals for their efforts in expanding the network. Developers can earn a portion of the sequencer fees generated from their smart contracts, providing them with a direct financial incentive. Furthermore, Mode's unique treasury system will automatically distribute rewards across the ecosystem, ensuring consistent engagement and support. Leveraging the modular OP stack, Mode is integrated into the super chain network, which encompasses both the base and OP mainnet. Users can benefit from a streamlined and intuitive blockchain experience through the Mode name service. In addition, the Mode bridge allows for effortless asset transfers between Layer 1 and the Mode platform, significantly enhancing the network's flexibility and accessibility for users. This comprehensive approach not only promotes growth but also deepens community involvement within the blockchain ecosystem, creating a vibrant and collaborative environment for all participants. Ultimately, Mode aims to redefine how blockchain interactions occur by prioritizing user engagement and economic incentives.

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.
