Slack Tipbot

coin-agnostic crypto Tipbot for Slack

Setup

We're using digitalocean.com so these instructions will be specific to that plaform.

Create and configure droplet

Create droplet

• Go to digitalocean.com and create a new droplet
  • hostname: CoinTipper
  • Size
    • I usually go w/ 2GB/2CPUs $20 month
  • Region
    • San Francisco
  • Linux Distributions
    • Ubuntu 14.04 x64
  • Applications
    • Dokku
  • Add SSH keys

Configure hostname

• Copy/Paste IP address into URL bar
  • Put in hostname
    • example.com
  • Check `Use virtualhost naming for apps
    • http://<app-name>.example.com
  • Finish Setup

Add DNS

• You'll need a domain for this. For this documentation I'm using example.com
• Point your domain's nameservers to digitalocean
  • ns1.digitalocean.com
  • ns2.digitalocean.com
  • ns3.digitalocean.com
• In digitalocean's DNS section set an A-Record for your hostname from your previous step
  • Make the hostname be the name of your app
    • foocointipper
  • Make the IP address be the one provided by digitalocean for your droplet.
• After the DNS propogates
  • In the Zone file of the DNS section of digital ocean you'll see:
    • foocointipper IN A 143.143.243.143
  • ping foocointipper.example.com
    • PING foocointipper.example.com (143.143.243.143): 56 data bytes

SSH into your new virualized box

• ssh root@ip.address.of.virutalized.box
  • If you correctly added your SSH keys you'll get signed in
  • Remove root login w/ password
    • sudo nano /etc/ssh/sshd_config
      • PermitRootLogin without-password

Compile your coin

For this example I'm using litecoin but the instructions should be similar for most other coins.

• Update and install dependencies
  • apt-get update && apt-get upgrade
  • apt-get install ntp git build-essential libssl-dev libdb-dev libdb++-dev libboost-all-dev libqrencode-dev
  • wget http://miniupnp.free.fr/files/download.php?file=miniupnpc-1.8.tar.gz && tar -zxf download.php\?file\=miniupnpc-1.8.tar.gz && cd miniupnpc-1.8/
  • make && make install && cd .. && rm -rf miniupnpc-1.8 download.php\?file\=miniupnpc-1.8.tar.gz
• Download the source code
  • git clone https://github.com/litecoin-project/litecoin
• Compile litecoind
  • cd litecoin/src
  • make -f makefile.unix USE_UPNP=1 USE_QRCODE=1 USE_IPV6=1
  • strip litecoind
• Add a user and move litecoind
  • adduser litecoin && usermod -g users litecoin && delgroup litecoin && chmod 0701 /home/litecoin
  • mkdir /home/litecoin/bin
  • cp ~/litecoin/src/litecoind /home/litecoin/bin/litecoind
  • chown -R litecoin:users /home/litecoin/bin
  • cd && rm -rf litecoin
• Run the daemon
  • su litecoin
  • cd && bin/litecoind
  • On the first run, litecoind will return an error and tell you to make a configuration file, named litecoin.conf, in order to add a username and password to the file.
    • nano ~/.litecoin/litecoin.conf && chmod 0600 ~/.litecoin/litecoin.conf
    • Add the following to your config file, changing the username and password
    • to something secure. Make sure to take note of the rpcuser and * rpcpassword because you'll need them in a couple of steps
      • daemon=1
      • rpcuser=litecoinrpc
      • rpcpassword=f0000b4444r
      • port=9333
      • rpcport=8332
      • rpcthreads=100
      • irc=0
      • dnsseed=1
  • Run the daemon again
    • cd && bin/litecoind
  • To confirm that the daemon is running
    • cd && bin/litecoind getinfo
  • Now wait for the blockchain to sync

Clone the CoinTipper Bot git repo

• git clone https://github.com/cgcardona/slack_tipbot.git
• Install bundler
  • apt-get install bundler
• Install Ruby 2.1.1 and rvm
  • \curl -sSL https://get.rvm.io | bash -s stable --ruby
  • To start using RVM you need to run source /usr/local/rvm/scripts/rvm
• Run bundle

Set up the Slack integration: as an "outgoing webhook"

• https://yoursite.slack.com/services/new/outgoing-webhook
• Write down the api token they show you in this page
• Set the trigger word. For the litecoin example above we use litecointipper
• Set the Url to the server you'll be deploying on http://example.com:4567/tip

Give your bot some attitude!

• Copy coin_config/litecoin.rb to a file in coin_config/ and name it after your coin.
• Open your newly copied file and change the name of the module to the same name as your coin.
• This file contains all the snippets of text, emojis, and variables needed to customize your bot's behavior and attitude

Launch the server!

• RPC_USER=litecoinrpc RPC_PASSWORD=your_pass SLACK_API_TOKEN=your_api_key COIN=litecoin bundle exec ruby tipper.rb -p 4567

Tested coins

This has been tested w/

• btc
• ltc
• florincoin
• doge
• zeta

Please let me know when you try it with other coins so that I can update the list.

Security

This runs an unencrypted hot wallet on your server. You should not store significant amounts of cryptocoins in this wallet. Withdraw your tips to an offline wallet often.
