Keoken 
Creates BCH tokens and send money between them for the Keoken protocol.
Installation
Add this line to your application's Gemfile:
gem 'keoken'
And then execute:
$ bundle
Or install it yourself as:
$ gem install keoken
Usage
It uses bitcoin-ruby, but you can use Trezor or Electrum, the most important command is the script, which you can obtain with token.hex, then you can send it as an output with a scriptPubKey and a value of 0. In order to crate a token you need two outputs, the change address with an amount less than original (for fees) and the other one for the script. To send money you need three outputs, the change address, the address who owns the recipient token and the script.
Create token and send it to the blockchain
Bitcoin.network = :testnet3
token = Keoken::Token.new(name: "test-keoken-bitex")
token.create(1_000_000)
key = Bitcoin::Key.from_base58("cShKfHoHVf6iYKZym18ip1MJFQFxJwbcLxW53MQikxdDsGd2ofBU")
script = token.hex
@transaction_token = Keoken::Backend::BitcoinRuby::Transaction.build_for_creation(key.addr, key, script)
transaction = Keoken::Bitprim::Transaction.new
transaction.send_tx(@transaction_token.raw)
Send token money and send transaction to the blockchain
Bitcoin.network = :testnet3
bitprim_transaction = Keoken::Bitprim::Transaction.new
assets = bitprim_transaction.assets_by_address('mro9aqn4xCzXVS7jRFFuzT2ERKonvPdSDA')
token = Keoken::Token.new(id: assets.first['asset_id'])
token.send_amount(500_000)
key = Bitcoin::Key.from_base58('cShKfHoHVf6iYKZym18ip1MJFQFxJwbcLxW53MQikxdDsGd2ofBU')
script = token.hex
@transaction_token = Keoken::Backend::BitcoinRuby::Transaction.build_for_send_amount(key.addr, 'mnTd41YZ1e1YqsaPNJh3wkeSUrFvp1guzi', key, script)
transaction = Keoken::Bitprim::Transaction.new
transaction.send_tx(@transaction_token.raw)
