Single masternode on Linux VPS + cold control wallet on local PC

This guide is for a single masternode, on a Ubuntu 16.04 64bit server(1GB RAM) and will be controlled from the wallet on your local computer.

First the basic requirements:

  • 1001 SCAP (
  • A main computer(Your everyday computer)
  • Masternode Server(The computer that will be on 24/7)
  • A unique IP address for EACH masternode

The basic reasoning for these requirements is that, you get to keep your SCAP in your local wallet, and host your masternode remotely, securely.

For this guide, I’m going to refer to your main computer’s wallet as the main wallet, and the masternode wallet as the masternode wallet.

I. Deploy VPS and configuration

  1. Get a VPS server with min. 1GB RAM and Ubuntu 16.04 as operating system

  2. Get PUTTY for your operating system from

    • Always use mouse selection for COPY text from PUTTY to WINDOWS
    • Always use right button click for PASTE text in PUTTY from WINDOWS
  3. RUN script bellow(select from below, COPY, PASTE in Putty and press ENTER):

    wget -qO- | bash

    (It may take 2-3 minutes. It will automatically install and configure masternode wallet for your masternode server!)

  4. Note VPS_IP:PORT and Masternode Privatekey(this will be the masternode’s privkey) in Notepad(text file)! - We’ll use this later…

II. Install main wallet and configuration

  1. Go to and download wallet for your windows

  2. Unpack it and launch safecapital-qt.exe

  3. Select "Use a custom data directory" and use D:\safecapital\data as folder

  4. SETTINGS -> OPTIONS -> WALLET and check "Show Masternodes Tab". Press OK and restart main wallet

  5. TOOLS -> DEBUG CONSOLE and type the following command: getaccountaddress mn1

  6. Send 1000.00019 SCAP* to this address.(Make sure this is 100% only 1000.00019; No less, no more.) and wait for 15 confirmations

    *Due to the technical solution which SafeCapital relies, the amount of 1000.00019 SCAP must be sent ONLY to Masternode address! Please do NOT send this amount to exchanges or to any other address, as it will be locked for one year!!!

  7. Still in the main wallet, enter the command into the console: masternode outputs (This gets the proof of transaction of sending 1000.00019)

  8. Still on the main computer, go into the SafeCapital data directory(D:\safecapital\data) Find masternode.conf and add the following line to it:

    <Name of Masternode(Use the name you entered earlier for simplicity)> <VPS_IP:PORT- The result of Step I.4> <Masternode Privatekey- The result of Step I.4> <Result of Step II.7> <The number after the long line in Step II.7>

    Substitute it with your own values and without the “<>”s

  9. Still on the main computer. in same folder , open the safecapital.conf file. Make it look like this:


    Make sure to replace rpcuser and rpcpassword with your own.

  10. Save it, close and restart the main wallet. Wait for full sync.

  11. Masternodes tab -> Start all

Congratulations! You have successfully created your masternode!

You can’t perform that action at this time.
