Manual

As by design, this application is intentionally tighly coupled with coinbase mainly because transactions made between coinbase users are made off-the-blockchain - in brief without paying transaction fees. So be sure to sign up there if you haven`t done this already.

In order to use the app properly one should /configure [coinbase email address] prior to start sending funds. One can change the email as many times as he/she wants. But keep in mind that one email is mapped to a single slack user (you can cannot have two or more emails configured at the same time). After a successful configuration one should receive the following message: Coinbase email configured successfuly! You are now able to make transactions.

Afterwards, typing /transaction in the slack's text box and filling all the all the required fields in the popped-up Transaction dialog will send the selected amount of funds to a selected user from this channel. If the transaction is successful one should see All good to go! You have sucessfuly created a transaction., otherwise an error message is displayed.
