A fast, thread-safe, simple, lightweight, batchable interface to the bitcoind JSON-RPC api. Uses HTTPClient for high performance.


Add this line to your application's Gemfile:

gem 'silkroad'

And then execute:

$ bundle

Or install it yourself as:

$ gem install silkroad


Initialize the client:

silkroad =

You can set a custom uri:

silkroad = 'https://rpcuser:[email protected]:31337'

Now you can make RPC API calls (see the API calls list). Pass params as per the spec, and the result will be returned as a primitive type (string, number, boolean, and nil) or structured type (hash, array), depending on the call:

silkroad.rpc 'getbalance', '[email protected]' # => 31337

Errors throw the Silkroad::Client::Error exception. Catch it if you want to do something custom:

  silkroad.rpc 'failcmd', 'fail'
rescue Silkroad::Client::Error => e
  puts "Error: #{e.inspect}"


If you use batching, it will throw all your requests into a JSON array, send them at once, and return all of them when they are done, per the JSON-RPC spec. Batch is much lower level, and does not raise exceptions on errors. You will need to look for the response[index]['error'] in the return and handle it.

response = @silkroad.batch do
  rpc 'getbalance', '[email protected]'
  rpc 'notworking', 'derp'

# response is:
  {result: 31337, error: nil, id: nil},
  {result: nil, error: {code: -32601, message: 'Method not found'}, id: nil}
