Berachain RPC: The Ultimate Guide to 101 Essential Commands

Introduction

Berachain RPC (Remote Procedure Call) is a powerful tool that allows developers to interact with the Berachain blockchain directly. It provides an interface to send and receive data from the blockchain, enabling the creation of custom applications and services. This comprehensive guide will introduce you to the basics of Berachain RPC and provide detailed instructions on using 101 essential commands.

Getting Started

Prerequisites

• Install a Berachain core wallet or node
• Create a RPC user and password

Establishing a Connection

To establish a RPC connection, you will need to use a command-line tool such as cURL or Postman. The following command establishes a connection using cURL:

curl -u [rpcuser]:[rpcpassword] -X POST http://[rpcserver]:[rpcport]/ -d '{"jsonrpc":"1.0","id":"curltest","method":"getblockcount","params":[]}'

Replace '[rpcuser]' with your RPC username, '[rpcpassword]' with your RPC password, '[rpcserver]' with your RPC server address, and '[rpcport]' with your RPC port (usually 18245).
