Cryptmon

A basic CLI app (for Linux and Mac currently, although other platforms might work) for displaying the price of Cryptocurrency coins, and alerting based off price thresholds with some built-in alert/notification providers.

Made partly as a custom tool to scratch an itch, but also as a new project with which to learn and experiment with the Rust programming language, as well as various HTTP/Web APIs for access to Crypto prices and alert/notification providers, and also to learn a bit more about Crypto exchanges and price tracking.

It's still in the developmental phase (although not a high priority for me), but is functional to a fair degree, although it still has some rough edges, and is very much designed with my limited use-cases in mind :)

Currently supported Price Providers (price data sources):

• CoinGecko
• CryptoCompare (note: sometime provides wrong prices in non-USD fiat currencies)
• CoinMarketCap (API key needed)

Currently supported Alert Providers:

• SMTP email sending (not compiled in by default - feature needs to be enabled in Cargo.toml or on the cargo command line for building)
• Textbelt SMS sending (API key needed)
• SimplePush phone notifications (API key and SimplePush App needed)
• PushSafer phone notifications (API key and PushSafer App needed)

in addition to built-in actions of print, which prints to the console, and showNotification which displays an OS alert.

a cryptmon.ini config file is needed (you can copy the example_cryptmon_config.ini example one as starting point) for configuration in the:

$HOME/cryptmon.ini

or:

$HOME/.config/cryptmon.ini

file path locations.

Building

cargo build --release

Should be all you need.

Running

Currently there are two modes: price view (the default), which displays a table of coin prices in the terminal, based off the: display.wantedCoins param in the cryptmon.ini config file, and alerts, which internally monitors prices for coins based off configured alerts in cryptmon.ini, and based off configured alert providers, will send alerts notifications if any of those trip.

To run the default price view, just run:

./cryptmon

From the directory where the executable is (target/release/).

This should show something like this, depending on your config params (and prices! :) ):

LTC   Litecoin       164.79    0.8658       0.53%     161.85     167.52

To run with alerts active (must be configured in cryptmon.ini first):

./cryptmon alerts

Possible Future Work

• More price providers
• More alert providers
• More configuration options
• More fine-grained alert threshold logic
• HTML price table output to file
• A GUI?
