Ethereum Layer-2 Support: Get RPC for Arbitrum, zkSync, Optimism on Chainnodes

There is more than one Layer-2 solution, with leading protocols being Optimism, Arbitrum, zkSync and Base. Essentially, different blockchains adopt different technological approaches to resolve the significant bottlenecks associated with Ethereum: Cost, Speed and Scalability.

Today, conversations on several layer-2 focused questions like, will all rollups become zk-rollup? what are the best infrastructure providers for Layer-2 blockchains, and what are the best blockchains to build on as a developer continues to populate the blockchain space?

Despite the ongoing debate, developers are left to make crucial decisions in two regards:

Selecting the most appropriate layer-2 blockchain, and
Choosing the best layer-2 blockchain infrastructure provider

This shows that for developers, the layer-2 solution with the highest total value locked or the service provider with the best online presence are not necessarily the most appropriate fit. Instead, available layer-2 chains and the reliability of an infrastructure service provider must be considered with their project's needs before they decide on the blockchain and infrastructure service provider to opt for.

The state of Layer-2 Blockchain adoption in 2025

Since inception, Layer-2 blockchains have continued to witness growing adoption. At the time of writing, over $37 billion is locked on layer-2 blockchains, and more protocols continue to adopt layer-2 chains.

In 2023, the decline in cryptocurrency trading volume did not impact Layer-2 adoption; instead, a 300% increase in smart contract deployment was noted on Arbitrum, Optimism and Polygon.

If you are currently building a decentralized application, here is an insight into what developers consider when selecting a blockchain infrastructure provider.

What to Consider When Selecting a Layer-2 Blockchain Infrastructure Provider

Interoperability and Compatibility: Seamless interoperability is the most sought-after feature in a layer-2 blockchain infrastructure because it ensures that a dapp runs efficiently across multiple chains. Compatibility with existing tools and protocols, such as the Ethereum Virtual Machine (EVM), is highly valued because it allows for easier integration and migration of applications.
Scalability and Reliable Performance: For every decentralized application, scalability is a primary concern. To ensure an optimal user experience and ensure that dapps run efficiently, developers must use solutions that can handle an increase in transactions and requests without compromising speed and efficiency.
Cost Effectiveness: From the upfront subscription fee to the maintenance cost and transaction fees, developers compare the competitive pricing models offered by a large ecosystem of service providers to manage their budget while scaling their applications.
Security and Decentralization: To protect applications against vulnerabilities and ensure optimal performance and speed, developers must consider the robustness and decentralized nature of an infrastructure. A highly decentralized network with a robust consensus mechanism is better suited to operate efficiently while protecting applications from attacks.
Developers' Support and Documentation: From the implementation process to fixing major errors, developers have a lot to gain from a network that provides instant support and readily available documentation to guide developers at different stages.

2. Custom Protocol Hosting

Building decentralized applications can come with unique features and needs. Chainnodes is dedicated to powering the future of blockchain decentralization and Web3 by providing developers with secure and high-performance infrastructures that are tailored to dApps' unique needs.

Additionally, Chainnodes provides 24/7 support via telegram and email, providing developers with on-spot troubleshooting guide and implementation instructions.

3. Validator-as-a-Service (VaaS)

Aside from developers, major players in the Proof-of-Stake ecosystem are validators. Chainnodes currently power both Layer-1 and Layer-2 Proof-of-Stake blockchains through an automated block validation service.

Chainnodes Validator-as-a-Service infrastructure allows users to automate the deployment, monitoring and maintenance of operations. By substituting the manual process with an automated one, validators can focus on core innovation while the infrastructure handles uptime, slashing protection, failover mechanisms and optimized performance.

It also provides insight into system features and available upgrades using real-time analytics.
