Hello Nurse (hello_nurse) is a bot that will transfer money to Dr. Otto bots when you vote a certain way.

For example, you can configure this bot to watch for 1% votes by you, and when that happens, transfer 2 SBD to your favorite pay-for-vote bot. The memo will be set to the post that got a 1% upvote.


To use this Radiator bot:

$ sudo apt-get install ruby-full git openssl libssl1.0.0 libssl-dev
$ gem install bundler
$ gem install bundler

I've tested it on various versions of ruby. The oldest one I got it to work was:

ruby 2.0.0p645 (2015-04-13 revision 50299) [x86_64-darwin14.4.0]

First, clone this gist and install the dependencies:

$ git clone
$ cd hello_nurse
$ bundle install

Edit the configuration file hello_nurse.yml

  :mode: irreversible

  :trigger_vote_weight: 2.00 %
  :enable_comments: true
  :max_vote_elapse: 600
    :active_key: 5JrvPrQeBBvCRdjv29iDvkwn3EQYZ9jqfAHzrCyUvfbEbRkrYFC
    :amount: 4.000 SBD
    :active_key: 5XXXBadWifXXXdjv29iDvkwn3EQYZ9jqfAHzrCyUvfbEbRkrYFC
    :amount: 4.000 SBD

:bots: booster

  :chain: steem

Before you run it, make sure you and understand and fully control the voter accounts. Any vote that matches the trigger weight will initiate a transfer. Before running this bot, ensure all automated voting has been disabled or else this bot may transfer unexpected amounts.

Then run it:

$ ruby hello_nurse

Check here to see an updated version of this bot:


Typically, you can upgrade to the latest version by this command, from the original directory you cloned into:

$ git pull

Usually, this works fine as long as you haven't modified anything. If you get an error, try this:

$ git stash --all
$ git pull --rebase
$ git stash pop

If you're still having problems, I suggest starting a new clone.


Problem: What does this error mean?
hello_nurse.yml:1: syntax error, unexpected ':', expecting end-of-input
Solution: You ran ruby hello_nurse.yml but you should run ruby hello_nurse.

Problem: Everything looks ok, but every time hello_nurse tries to post, I get this error:
`from_base58': Invalid version (RuntimeError)
Solution: You're trying to vote with an invalid key.

Make sure the .yml file voters item have the correct account name and WIF posting key.

Problem: The node I'm using is down.

Is there a list of nodes?

Solution: Yes, special thanks to @ripplerm.
