Cosmos WalletMon

Cosmos WalletMon is a simple script that helps send notifications whenever a wallet drops below a specified threshold balance. This was inspired by me always forgetting to check whether my Restake hot wallet had funds to keep auto-compounding delegate's balance.

Support Chains

Chain data is obtained from the Chain Registry.

Any chain that has a chain_name set in the chain's chain.json and asset base in the assetlist.json files is supported.

Usage

The easiest way to run this is using docker-compose.

Docker-Compose

Clone the repository

git clone https://github.com/Crypto-Chemistry/walletmon.git

Move example.docker-compose.yml to docker-compose.yml

mv example.docker-compose.yml docker-compose.yml

Edit docker-compose.yml and modify the variables. After the -a flag, a list of space-separated addresses to monitor should be provided. These do not need to belong to the same chain. After the -d flag, add the Discord webhook for the channel that you want to receive low balance notifications on.

Example docker-compose.yml command segment:

command: "walletmon.py \
              -a kujira1tfknxt857r4lm8eh2py5n3yq00t3mq5eerh6qs clan1wg7nrqc29veuzw9p6ujhad697a3tpzl3zrfplr \ 
              -d https://discord.com/api/webhooks/1234567890123456789/abcdefghijklmnop-1A-2B3CD4-e5f6g7h8i9j10 \
              -g 100000"

Build the image

docker-compose build --no-cache

Run the application (It acts as a one-shot similar to Restake. To configure it as a repeated service, see Configuring a WalletMon Service)

docker-compose run --rm walletmon

Running from source

Running this application from source is a bit more work to set up reliably and comes with additional requirements.

Python 3.10 or greater must be installed for this function properly. However, it has only been tested on Python 3.10.5 so far.

Clone the repository

git clone https://github.com/Crypto-Chemistry/walletmon.git

Switch to the repo directory

cd walletmon

Pull down the library dependencies

pip3 install -r requirements.txt

Run the walletmon.py script with the required arguments

python3 walletmon.py -a address1 address2 address3 -d discord_webhook_url

Example command:

python3 walletmon.py -a kujira1tfknxt857r4lm8eh2py5n3yq00t3mq5eerh6qs clan1wg7nrqc29veuzw9p6ujhad697a3tpzl3zrfplr \
                     -d https://discord.com/api/webhooks/1234567890123456789/abcdefghijklmnop-1A-2B3CD4-e5f6g7h8i9j10 \
                     -g 100000

Update Instructions

To update to a newer version navigate to where the repo is cloned and run the following commands

git fetch --all
git pull

If using the Docker Compose method to run the application, make sure to force rebuild the image:

docker-compose kill
docker-compose build --no-cache

If running from source, make sure to reinstall the requirements.txt file in case new dependencies have been added: pip3 install -r requirements.txt

Configuring a WalletMon Service

To configure WalletMon as a service, first create a service file.

sudo nano /etc/systemd/system/walletmon.service

Copy the following contents into the walletmon.service file, replacing the WorkingDirectory variable with the path to where the repo is cloned.

[Unit]
Description=Cosmos Wallet Monitoring Service
Requires=docker.service
After=docker.service
Wants=walletmon.timer

[Service]
Type=oneshot
WorkingDirectory=/path/to/walletmon
ExecStart=/usr/bin/docker-compose run --rm walletmon

[Install]
WantedBy=multi-user.target

Next, create the timer that dictates how often the service is called.

sudo nano /etc/systemd/system/walletmon.timer

Copy the following contents into the walletmon.timer file. Adjust the OnCalendar variable to change how frequently the application runs. It's configured to run every hour by default.

[Unit]
Description=Cosmos Wallet Monitoring Timer

[Timer]
AccuracySec=1min
OnCalendar=*-*-* *:00:00

[Install]
WantedBy=timers.target

Run the following commands to start and enable the service/timer:

sudo systemctl enable /etc/systemd/system/walletmon.service
sudo systemctl enable /etc/systemd/system/walletmon.timer
sudo systemctl start /etc/systemd/system/walletmon.timer

Available Parameters

Parameter	Type	Required	Description
-a,--addresses	String or multiple strings	Yes	Addresses to check balances
-d,--discord	String	Yes	Discord webhook url to send notifications to
-l,--label	String	No	Wallet Label Identifier for alert clarity
-u,--userid	String	No	Discord User by UUID to tag in alerts
-t,--threshold	String or multiple strings	No	Chain specific thresholds for wallet balances before sending notifications
-g,--globalthreshold	Int	No	Global threshold for wallet balances before sending notifications
