Node Tutorial (Generic)

Wallets, no matter the type, are merely programs. They run on a computer, and communicate with CAS by various means. Usually, the program is a "daemon", a type of program on a Linux-based server that runs in the background. No matter which type, the program runs on a public server and listens for applications to connect and send/receive information.

Each daemon listens on a certain "port". The port is specific to each server and the daemon(s) it runs. The Internet address of the server ("host") and the port it listens on must be correctly specified in CAS for a successful data conversation.

The General Bytes CAS supports many different cryptocurrencies. Each one requires different parameters, and this is turn varies by the wallet provider you elect to use. This information may be known definitively to GB, and the wallet will be pre-populated with wallet providers (e.g. Coinbase, Kraken, etc). Other wallets are unknown to GB, but you have the option of using those wallets if you can acquire the required parameters from the wallet provider.

This article is intended to help with you determine those parameters.

RPC is an acronym for Remote Procedure Call. It is the method commonly used for programs running on Internet servers to communicate with each other. The parameters required in Crypto Settings are for RPC communication.

General Bytes support will never ask you for your RPC credentials, nor should you offer them. This information permits access to your funds, and we would be reckless in accepting that responsibility. You must do this part yourself.

Parameters must be precise. The slightest typo will cause the whole conversation to fail. Every piece must be supplied by your wallet provider, or in the case of local nodes, it must match exactly the node configuration. The  parameters required may include:

Protocol: this is the format used to transfer information. This is always "http".

Host: this is the IP address of the server hosting the wallet. If you have installed, configured and implemented your own node, then you should already know the IP address of the server you installed the node on. If it's a local node, then you'll most likely use

Port: specified by the wallet operator, it's a 4-5 digit number and varies by the type of wallet. The operator may not use the conventional port suggested by the community, you should verify with the operator. Some examples of conventional ports:

  • 8332: Bitcoin Core

  • 8332: Bitcoin Cash

  • 8545: Ethereum

  • 8333: Litecoin

  • 18081: Monero

  • 9998: DASH

  • 11001: Sumcoin

User: this is the "user" portion of the RPC credentials given to you by the wallet operator. If you created your own node, then you set your own "user".  RPC credentials are entirely different than account credentials, and the two are rarely identical.

Password: this is the "password" for the RPC user specified above. If you use a wallet provider, use the password they specify for your account. This may be the same as your user password, or it may be different, and it is completely dependent upon the wallet provider's discretion.

Account: this is typically set when everybody uses the same user/password (above). This identifies your account from everyone else's. In some cases "account" identifies your wallet name, as specified by the wallet provider. When implementing a local BTC node, you may have many different wallets for different purposes or BATM's.


A typical sample "parameter" for a local Bitcoin Core node (bitcoind) will look something like:

  • There are no quotes.

  • All fields are seperated by a colon (":").

  • Empty fields are skipped ("::"). NO SPACE BETWEEN THE COLONS!

When you have configured your parameters correctly, test them:


If you've entered the correct parameters, the appropriate tests will show green:


And that's it. You're ready to start selling crypto!
