Money gem's Bank implementation to Cryptocompare API to do cryptocurrency exchange, like converting Bitcoin to Ethereum.
Add this line to your application's Gemfile:
gem 'money-bank-cryptocompare'And then execute:
$ bundle
Or install it yourself as:
$ gem install money-bank-cryptocompare
First you need to define the cryptocurrency you need:
require 'money'
curr = {
:priority => 1,
:iso_code => "IOT",
:name => "IOT",
:subunit => "IOT",
:subunit_to_unit => 1,
}
Money::Currency.register(curr)Initialize the bank, and call exchange_to as you normally would.
require 'money/bank/cryptocompare'
bank = Money::Bank::Cryptocompare.new
bank.exchange_with(Money.new(100_000_000,'BTC'), 'IOT')
# Set default bank to allow auto currency conversion
Money.default_bank = bank
Money.new(100_000_000,'BTC').exchange_to('IOT')Cryptocompare offers some options, such as using specific exchange for rate lookup. This can be set when initializing the bank:
Money::Bank::Cryptocompare.new(options: {'e' => 'Kraken'})A list of supported exchanges are listed here.
If we want to set a rates store, pass it with the :rates_store key (different to standard bank method signature):
Money::Bank::Cryptocompare.new(rates_store: rates_store)
