def deps do
  [
    {:multichain, "~> 0.1.0"}  
  ]
end

2. Get the dependency

mix deps.get

3. Add your Multichain node configuration into config.exs, match the value to your own credential.

config :multichain,
  protocol: "http",
  port: "1234",
  host: "188.199.177",
  username: "multichainrpc",
  password: "xxxxxxxxxxxxxxx",
  chain: "chain1"

Done! Now you can use it inside your Module.

How to use

Some of example can be seen below:

Multichain.api("listaddresses", ["*", true, 3, -3])

Multichain.api("getinfo", [])

Multichain.api("help", [])

iex(1)> Multichain.api("validateaddress", ["1KFjut7GpLN2DSvRrh6UATxYxy5nxYaY7EGhys"])
{:ok,
 %{
   "error" => nil,
   "id" => nil,
   "result" => %{
     "account" => "",
     "address" => "1KFjut7GpLN2DSvRrh6UATxYxy5nxYaY7EGhys",
     "ismine" => false,
     "isscript" => false,
     "isvalid" => true,
     "iswatchonly" => true,
     "synchronized" => false

TODO

Some of common task is a combination of multiple api call. Previously has been implemented in python and nodejs. We should make it here too to simplify common operation.

• Check balance api
• Create Address api
• Publish Stream api
• Retreive stream api
• Create new asset
• Reissue new asset
• List asset
• FIX STREAM DECODEE
