CryptBroTrader3000

Trading crypto assets the old-fashioned way, bro! (aka by yelling over the phone at some rando)

Demo

Call +1 (909) 787-BRO8 to try it out. Note: No real ETH or BTC is being traded on this number (and I disabled the phone number security check). It's just to try out the interface.

At the prompt, tell it to "BUY BUY BUY" or "Sell right now!"

Commands

You can say any phrase you want as long as they include a command word:

BUY - will buy crypto
SELL - will sell crypto
wait or hold - will wait three seconds before next prompt

If you don't give a command after two seconds, the call will end. GOTTA BE FAST, BRO

Requirements

Before getting started, you need the following setup:

Google Cloud Functions
A Twilio account with a phone number capable of receiving calls
A GDAX account with an API key setup

Setup

Create a file in the root directory called .env

You'll need to add the following config options:

CLOUD_ROOT - the root URL for your cloud function project
- Example: https://us-central1-MY-DOPE-PROJECT.cloudfunctions.net/
GDAX_API_KEY - The GDAX API Key
GDAX_PASS_PHRASE - The passphrase that was used to create your GDAX API key
GDAX_API_SECRET - Your GDAX API key secret
TRADE_PRODUCT_ID - What you're trading. Can be ETH-USD or BTC-USD
TRADE_USD_COST - The amount of USD that will be sold/bought for each trade
OWNER_PHONE - Telephone number of the owner (to prevent unathorized trades)

Next, you'll need to deploy both of the cloud functions. That'll look something like this:

gcloud beta functions deploy hello --entry-point hello --stage-bucket <YOUR CLOUD BUCKET HERE> --trigger-http

gcloud beta functions deploy command --entry-point command --stage-bucket <YOUR CLOUD BUCKET HERE> --trigger-http

Then, when both functions are done deploying, paste the URL for the "hello" function you just deployed into the Configure settings for your Twilio number

You're good to go!
