List of the Top 6 Layer 2 Protocols for OKX Wallet 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.
