Introduction

Cryptocheck is a desktop application whose primary purpose is to continuously monitor balances on your cryptocurrency accounts and raise alert in case of any change detected on your accounts. When alert is raised, an alert message shows up on your PC and optionally an e-mail notification is sent to your e-mail address. To verify balances, Cryptocheck connects to known online block explorer services.

It can be useful for long-term investors who have many different cryptocurrencies in their portfolio and do not make transactions very often. With Cryptocheck you no longer need to connect to all your different wallets with different passwords or check many different block explorer sites to simply just check that your money are still there.

With Cryptocheck you can perform checks of your portfolio either manually (on request) or it can be set to perform checks periodically with a given time period.

Cryptocheck also provides simple calculations of profit and current value in fiat currency and history charts mapping your portfolio history (profit/loss, portfolio structure, coin balances and rates).

Plus there is also a server node modality – a mix of PHP and Python scripts that can run on your server. Usually it is used together with the desktop application. The purpose of Cryptocheck server node is to perform continuous portfolio checks that are independent on your PC and therefore continue running when you e.g. turn off your PC. When you turn on your PC again after some time, the desktop application will connect to the server node and download all the latest check results and history data from the server. The server node has a web browser mobile-friendly user interface and can be used also separately as an online alternative to the desktop application (although it lacks the history charts functionality).

Checking addresses in your checklist
  • To perform a check manually click Check now icon in the main toolbar (or press F5).
  • To start periodic checks click Continual check icon in the main toolbar. You can change the frequency of checks in Settings → General → Continual check interval.
  • To perform checks on a remote server, see section Server node.

When a check is being performed, the progress is reported in the status bar.

If a check results with Alert! or Increased balance statuses, a message informing about this status will show up on your screen.


Statuses

Checks performed by Cryptocheck can end with different statuses. These can have different reasons.

Unknown
Status has not been checked yet after program start or after settings change. Press F5 to update the status.

OK
All addresses show correct balance corresponding to preset expected balances.

Increased
Good news, balance of some of your addresses in checklist has increased. You should update the expected balance value for these particular addresses.

Failed
Check of some of your addresses in checklist has failed. It may be caused by incorrect address details, unavailable internet connection or temporary failure of some of the integrated block explorer API services. Try to update the status later.

Alert!
Balance of some of your addresses in checklist is lower than expected balance. Please check all addresses with Alert! status. This may be caused just by incorrectly set expected balance value.

Advanced functions
History logging

Crytocheck can save results of performed checks and display how they evolved in time in the History charts view mode. History data logging can be turned on/off (by default it is on).

To set up history data logging:

  1. Click the settings icon in the main toolbar.
  2. Go to the History page.
  3. Check the Log history data option.

Server mode

In this mode, instead of performing checks on its own, Cryptocheck will periodically connect to your server node and download the latest check results and history data from there.

To set up server mode:

  1. Install and set up Cryptocheck server node on your server.
  2. Click the settings icon in the main toolbar.
  3. Go to the Server mode page.

  7. Adjust the Server connect interval if desired. This time specifies how frequently Cryptocheck will connect to the server node to check if any new data are available.
  8. Test the connection by clicking the Test connection button.
  9. Click OK to save the settings.
  10. In some cases Cryptocheck will ask you whether you want to download configuration from the server or upload your local configuration to the server. Here configuration = checklist (list of all your addresses) and some settings (Total investment, Main fiat currency).

Amend history data

By default only data from the successful checks performed by Cryptocheck are added to the history data plotted in the History charts view. But what if you are a new user of Cryptocheck or your computer was off for some time and now there is a gap in the history data?

You can manually amend history data by data based on historical cryptocurrency and fiat rates retrieved from online resources. To do this, follow the instructions below:

  1. Switch to History charts view by clicking the chart icon in the main toolbar.
  2. Click the History tools button and select Amend history data... option.
  3. In the Amend history data dialog, fill in all the values and press Amend. To add multiple cryptocurrencies, repeat this step.
  4. Close the Amend history data dialog.
Update

Cryptocheck automatically checks for updates. If a new version is available, a button New version available will appear in the top right corner of the main window.

To perform update:

  1. Click the New version available button.
  2. A dialog will show up summarizing changes in the new version. If you wish to proceed, click Yes.
  3. Cryptocheck will download some files, terminate the application and start the update process.
  4. Wait until the update process finishes, Cryptocheck will then be restarted.
Server node

As already mentioned, Cryptocheck server node is a mix of PHP and Python scripts that can run on your server. Usually it is used together with the desktop application. The purpose of Cryptocheck server node is to perform continuous portfolio checks that are independent on your PC and therefore continue running when you e.g. turn off your PC. When you turn on your PC again after some time, the desktop application will connect to the server node and download all the latest check results and history data from the server. The server node has a web browser mobile-friendly user interface and can be used also separately as an online alternative to the desktop application (although it lacks the history charts functionality). Since it is based on PHP, it communicates through standard HTTP (port 80) and HTTPS (port 443) protocols and therefore can penetrate most company firewalls etc.


Installation

You will need a server connected to the internet. Download the latest Cryptocheck server node files here or from the repository. Proceed according to the instructions in the included README.txt file.

Usage
  1. Access the server node from your internet browser.
  2. Log in with your credentials.
  3. Create your checklist. There are two possible ways.
  4. Navigate to the Service page.
  5. Click Start button. This will start periodical checks on the server. After a short while a log record should show up in the Log section and also results of the last check should show up in your connected desktop application.
  6. You can also navigate to the Status page to review the results of the last check.
