Automagically buy BTC, ETH or LTC on Coinbase, based on user defined thresholds.

Tradingbots: Typically, bots perform tasks that are both simple and structurally repetitive, at a much higher rate than would be possible for a human alone.

Architecture

Prerequisites

Yarn

For node module management Coinboss uses Yarn over NPM.

To install yarn globally on your machine please check Installing Yarn.

After that you can install all service dependencies with:

yarn

Coinbase

You need a Coinbase.com API key with the following permissions:

• wallet:accounts:read
• wallet:buys:create
• wallet:payment-methods:read
• wallet:sells:create

2. Install development dependencies

yarn

3. Setup environment

cp .env.example .env.dev

4. Update configuration within .env.dev

5. Deploy your Coinboss

STAGE="dev" yarn run deploy

How

Coinboss is triggered based on CloudWatch alarms. The thresholds can be found within the projects .env.example.

Test

For testing Coinboss uses Jest, for more information please check their documentation.

NOTE: To update Jest snapshots supply -- -u to any of the test commands.

Running the tests

yarn run test
