Arbitrum (ARB)

Arbitrum API Documentation with NOWNodes

To interact with Arbitrum ONE, you need to connect to an Arbitrum node via API. Like Ethereum, Arbitrum clients support the Arbitrum RPC (JSON-RPC) standard, which provides a unified set of methods for reading blockchain data, sending transactions, and executing smart contracts.

Arbitrum RPC is lightweight, stateless, and JSON-based, working seamlessly over HTTP. It enables developers to query chain data, track transactions, and interact with the Arbitrum Ethereum Virtual Machine (EVM) just as they would with Ethereum, but with Arbitrum’s scalability and lower fees.

With NOWNodes Arbitrum API, you get instant access to Arbitrum ONE without maintaining your own infrastructure. Our service ensures reliable connections, real-time blockchain data, and fast responses.

NOWNodes Arbitrum Interfaces:

• Arbitrum EVM RPC – Full Arbitrum RPC access to execute smart contracts, query blockchain state, and send transactions.
