Auto-Compound your staking rewards on the Crypto.org chain!
This guide is purposely not going into details to keep it short and (hopefully) simple. I am assuming that you know how to work with the different tools mentioned. As terminal, I’ll be using PowerShell 5.1.
Note: as of writing, the script is only compatible with version
2.1.2. Newer releases supporting croeseid (version 3.0.0 and higher) are not working yet!
Download the latest stable release from GitHub:
Please make sure you get the correct URL from the Releases page as this one may be outdated in the future!
# Download Archive Invoke-WebRequest -Uri "https://github.com/crypto-org-chain/chain-main/releases/download/v2.1.2/chain-main_2.1.2_Windows_x86_64.zip" -OutFile "./chain-maind.zip" # Unpack Archive Expand-Archive -Path "./chain-maind.zip" -DestinationPath "./" -Force
Now there should be a directory called
bin in the current directory. In this directory is the main executable
Now we have
chain-maind available and ready to use. Next is configuring it by adding your wallet. You can change the name of your wallet, I’ve chosen “DeFiWallet” in this example, but the name really doesn’t matter honestly.
Invoke-Expression ".\bin\chain-maind.exe keys add DeFiWallet --interactive"
This command will now prompt you to enter your mnemonic phrase. Make sure you only separate the words by a blank space and not a comma or anything else, otherwise the command will fail.
The result should look something like this:
- name: DeFiWallet type: local address: cro1ecwcn9tnla7tuzruhfc67z2ulvtl3340227a3w pubkey: cropub1addwnpepqvdajxswcsnfhj9j08key8xagauendryg840en76xtsmnxtmcqhrvvy6h8r mnemonic: "" threshold: 0 pubkeys: 
With this being done, you can now already interact with the Crypto.org chain and execute transactions from your wallet.
In order to run the script provided by Samuel, we must make sure that Python3 and all required dependencies are installed:
First, get the latest version of Python3 from their downloads page and install it:
Make sure you also add Python to your
PATH variable. The rest of this post is assuming you did that.
python is not a known command to Windows after installing, you have to reopen PowerShell. In some cases even restart Windows.
Afterward, it’s time to install the required dependencies:
pip3 install pexpect
Download & Configuration of the script
Next, you have to download the script and modify all required parameters.
This is a modified version which fixes a few issues/bugs that were not covered in the original script. Also, a few changes were made, because the code from the
pexpect module was not compatible with Windows.
Invoke-WebRequest -Uri "https://gitlab.com/-/snippets/2174318/raw/main/withdrawdelegateshare.py" -OutFile "./withdrawdelegateshare.py"
Once the download is completed, we have to set the files permission. With Windows ACLs being pretty complicated, it is easier to do this in the GUI. (Rightclick -> Properties)
Windows does not ask for any password for your keyring (at least on my machine) so you could ignore this step but I’ll do it for good measure anyway.
Click on one of the images to see them full screen.
After settings the permissions, open the file with any text editor and adjust the following variables:
Note: As of writing this article, Windows does not ask for a password for the keyring on my machine. Therefore the
password field will be ignored in the current version of the script. If this is the case on other systems, please let me know and I’ll update the script.
# Address of the validator # this is the address of X Staking validator = 'crocncl14vxzdsxtmat7hvz58trk823adg3pjh4xh6ghm6' # Your own CRO Address own_address = 'cro1ecwcn9tnla7tuzruhfc67z2ulvtl3340227a3w' # Password of your keyring password = 'HiI!mP4ssw0rd' # Folder in which the chain-maind executable is # Use the full path and don't use relative paths! chain_maind_directory = 'C:\\Users\\simon\\Desktop\\CRO-TEST\\bin'
Make sure you replace single
\ by double
\\ in the path
Note: If you have questions about the default validator X Staking, you can find more information about him below (here).
Everything is set up now. Every time you want to compound your stake just call the script and all your CRO from your wallet (and staking rewards) will be staked.

Open the Task Scheduler and click on “Create new Basic Task”. Now follow the images below.
- In Trigger, just define some trigger that fits your need
- In Start a Program, make sure you use the absolute path to your python script
- Make sure you replace single
\\in the path
Click on one of the images to see them full screen.
You can now modify the task in the Task Scheduler by for example adding additional triggers. Or you can also manually start the task.
Note: I still had Python2 installed as well as Python3 and thus the Scheduler decided to run the script using Python2. If this is the case either uninstall Python2 if you don’t need it anymore, or replace the program “
python” (4th screenshot) with the absolute path to the
We’ve already set file permissions so that nobody else can get the password from the python script. But what about your system, especially if you’re running it on a server?
It does not matter if you’re running it on a Windows Server or your home PC. Everyone who has access to your Windows user account can access your coins!
Make sure you take care of at least the following:
- Make sure you use a strong password
- Disable automatic login
- Lock your screen whenever you leave your PC (
CTRL + L)
A huge thanks to Samuel (X Staking) for doing the hard work and providing this script!

Future updates of the Crypto.org Chain can and will modify chain-maind. Make sure you are always running the same version that all validators are using.
