Best Layer 2 Protocols for OKX Wallet

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.

Starknet functions as a decentralized ZK-Rollup on Ethereum, operating without permission and allowing any decentralized application (dApp) to attain boundless computational scale while maintaining Ethereum's security and composability.
