What is an RPC?

When a user performs a DeFi transaction on a dApp, wallet, or marketplace, they interact with the blockchain. In doing so, they will inevitably interact with a range of different smart contracts based on whether they’re orchestrating a transaction, getting their balance, or utilizing a blockchain protocol. RPCs play a vital role in these processes as they define the rules for transmitting information and establishing connectivity with servers.

What is a JSON-RPC?

JSON-RPC is a protocol for performing remote procedure calls using JSON as the message format, and it is based on the same general principles as other RPC protocols. By using JSON-RPC as the communication protocol, Web3 applications can create a streamlined and consistent process for interacting with the blockchain, regardless of the specific blockchain implementation being used. These requests can include commands to read or write data to the blockchain, such as querying an account balance or submitting a transaction. The server processes these requests and returns the appropriate response to the client.

What is an Arbitrum RPC Endpoint?

Arbitrum is a layer-2 Ethereum scaling solution that aims to resolve issues related to high gas fees, network congestion, and scalability. Arbitrum RPC endpoint is like a doorway that allows you to connect to the Arbitrum network and interact with it through an API. Think of it as a way for your application to talk to the Arbitrum network and send commands, like sending transactions or querying the state of the network. It’s like having a direct line of communication between your application and the Arbitrum node, making it easy for you to interact with smart contracts on the network.

Using Omnia, a user can seamlessly create an Arbitrum custom RPC endpoint that is secure, private, and tailored to the user’s individual needs. Omnia allows users to create endpoints on HTTP or WebSockets.
