List of the Top 5 Layer 2 Protocols for Rabby in 2026

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.

Hemi introduces a groundbreaking modular Layer-2 blockchain framework that seamlessly fuses the strong security of Bitcoin with the versatile programmability of Ethereum by embedding a full Bitcoin node within an Ethereum-compatible framework known as the Hemi Virtual Machine (hVM). This pioneering architecture allows developers to craft Solidity smart contracts that can interact with Bitcoin data directly, eliminating the need for bridges or synthetic assets. Through its distinctive Proof-of-Proof (PoP) consensus method, Hemi ensures “superfinality,” linking transactions to Bitcoin blocks to maintain high integrity and protect against reorganizations, while also facilitating swift finality. Furthermore, the Hemi Bitcoin Kit (hBK) provides developers with vital resources to build genuine Bitcoin-centric DeFi solutions, such as lending, staking, automated market makers, MEV systems, and multi-chain DAOs, all utilizing real BTC for collateral or yield generation. Consequently, Hemi not only broadens the horizons of decentralized finance but also enhances collaboration between two of the most influential blockchains in the cryptocurrency world. Ultimately, this innovative framework sets the stage for unprecedented interoperability and financial possibilities within the blockchain ecosystem.
