Subkey is a command-line utility for the Substrate framework used to create and manage keys, sign and verify signatures and interact with the keystore file. In this article, we will demonstrate how to build a subkey tool from the source code and then install it so that it is available anywhere in the system.

The Substrate is an open-source blockchain framework. This article will list all the command line arguments available for the Substrate version 3.0 as they are displayed when running substrate --help command. Additional information has been added for some of the options and flags.

I was exploring the Substrate Blockchain the other day and was going through "Create Your First Substrate Chain" tutorial. I was building the Substrate node template on a Linux VPS and after successfully running the node and starting the Substrate Front End Template, the front-end was not accessible when trying to connect to it from my browser remotely as I was getting the "Error Connecting to Substrate [object Event]" error message.
