Best Layer 2 Protocols for Rabby

The next-generation layer 2 solution for Ethereum decentralized applications (dApps) allows developers to leverage their preferred tools while achieving cost-effective scaling for their projects. In this ecosystem, an aggregator functions similarly to a node in the Ethereum network, enabling client software to perform remote procedure calls (RPCs) to interact with an Arbitrum chain via a standard API. Once a client makes a request, the aggregator interacts with the EthBridge to generate transaction results, akin to the operation of an Ethereum node. Although most clients will typically route their transaction submissions through an aggregator for efficiency, it is not a strict requirement for operation. There are no restrictions on the number of aggregators that can be established, nor on who is eligible to serve as one. To enhance processing efficiency, aggregators often consolidate several client transactions into a singular message for submission to the Arbitrum chain. Additionally, Arbitrum features a specialized Sequencer that has the capability to prioritize transaction ordering and provide rapid transaction receipts, further optimizing the user experience. This innovative structure opens up new possibilities for developers looking to enhance their dApps on Ethereum.

Mode is an Ethereum Layer 2 solution that incentivizes users for expanding its network through innovative economic strategies. This platform is creating a novel on-chain economy that compensates individuals for their contributions to network expansion. Developers can receive a share of the sequencer fees generated through their smart contracts. Additionally, Mode's innovative treasury will facilitate automated rewards throughout the ecosystem. Built on the modular OP stack, Mode is part of the super chain network, which includes both base and OP mainnet. Users can enjoy a streamlined, user-friendly blockchain experience with the Mode name service. Furthermore, the Mode bridge enables seamless asset transfers between Layer 1 and the Mode platform, enhancing the overall flexibility and accessibility of the network for its users. This multifaceted approach not only fosters growth but also strengthens community engagement within the blockchain space.

Hemi represents a revolutionary modular Layer-2 blockchain framework that effectively combines the robust security of Bitcoin with the flexible programmability of Ethereum by integrating a complete Bitcoin node into an Ethereum-compatible environment, referred to as the Hemi Virtual Machine (hVM). This innovative setup empowers developers to create Solidity smart contracts that can directly utilize Bitcoin data without the need for bridges or synthetic assets. Through its unique Proof-of-Proof (PoP) consensus mechanism, Hemi provides “superfinality,” anchoring transactions within Bitcoin blocks to ensure high integrity and resistance to reorganizations, while also enabling rapid finality. Additionally, the Hemi Bitcoin Kit (hBK) equips developers with essential tools to craft authentic Bitcoin-driven DeFi solutions, including lending, staking, automated market makers, MEV systems, and multi-chain DAOs, leveraging actual BTC for collateral or yield generation. As a result, Hemi not only enhances the capabilities of decentralized finance but also fosters greater integration between two of the most significant blockchains in the ecosystem.

Polygon is the global leader in blockchain scalability solutions, offering an advanced infrastructure that transforms how money and data move across the internet. Purpose-built for real-time transactions, Polygon enables instant settlement, high throughput (1,000+ TPS), and transaction costs as low as $0.001. With over 5.3 billion transactions processed and $141 billion in transfer volume, it has become the backbone for digital payments, DeFi, and stablecoin ecosystems. Enterprises leverage Polygon’s robust framework to eliminate wire fees, improve liquidity, and ensure compliance—all while maintaining speed and transparency. The network’s aggregation layer, zkEVM, and AggLayer CDK provide developers with modular scalability for any use case—from tokenized assets (RWA) to cross-border payments.
