Validation Cloud’s Node API Now Supports Arbitrum RPC

Arbitrum is now integrated into Validation Cloud’s Node API. Validation Cloud is proud to support Arbitrum developers with our fast, secure, and reliable node infrastructure.

What is Arbitrum?

Arbitrum is a Layer 2 scaling solution designed to enhance the Ethereum blockchain by accelerating smart contract transactions and reducing transaction costs. As a Layer 2 solution, Arbitrum works to extend the capabilities of the primary Ethereum blockchain (Layer 1) by handling complex computational tasks like transaction processing and data storage on a secondary chain. This setup allows the Layer 2 chain to execute smart contracts swiftly, while the Layer 1 blockchain remains responsible for data storage. Arbitrum plays a crucial role by processing and batching blockchain transactions. This approach significantly alleviates congestion and reduces the costs associated with transactions on the main network.

Arbitrum employs rollup, which involves processing transactions off-chain in a two-layer architecture before the results are finalized on the main blockchain. The advantage here is that instead of needing to validate each transaction individually, the blockchain confirms a batch of transactions all at once, enhancing efficiency and scalability. Unlike some other Layer 2 solutions, such as sidechains, rollups like those used by Arbitrum derive their security directly from the main blockchain, ensuring robust protection for users. In particular, Arbitrum uses a type of rollup called optimistic rollups to achieve its scaling benefits.

Arbitrum RPC

Remote Procedure Calls (RPC) are a critical component in blockchain architectures, enabling the execution of functions on a remote server—essentially acting as the backbone for many decentralized applications. By supporting Arbitrum RPC, Validation Cloud facilitates a direct communication line with the Arbitrum blockchain, allowing developers to request and retrieve information, initiate transactions, and interact with the blockchain in real-time.

How to Connect to Arbitrum

Users can get started building on Arbitrum today at validationcloud.io. Validation Cloud offers up to 50 million Compute Units (CUs) per month for free to start building your applications. For limitless scalability, users can upgrade to the Scale Plan for unlimited CUs, zero rate limits, and a global delivery network. We’re looking forward to seeing what Arbitrum developers will create by building with Validation Cloud's performant Node API.
