EthereumJSONRPC

Ethereum JSONRPC client.

Configuration

Configuration for parity URLs can be provided with the following mix config:

config :ethereum_jsonrpc,
  url: "https://sokol.poa.network",
  trace_url: "https://sokol-trace.poa.network",
  http: [recv_timeout: 60_000, timeout: 60_000, hackney: [pool: :ethereum_jsonrpc]]

Note: the tracing node URL is provided separately from :url, via :trace_url. The trace URL and is used for fetch_internal_transactions, which is only a supported method on tracing nodes. The :http option is passed directly to the HTTP library (HTTPoison), which forwards the options down to :hackney.

Testing

By default, mox will be used to mock the EthereumJSONRPC.Transport and EthereumJSONRPC.HTTP behaviours. They mocked behaviours returns differ based on the EthereumJSONRPC.Variant.

`EthereumJSONRPC.Variant`	`EthereumJSONRPC.Transport`	`EthereumJSONRPC.HTTP`	`url`	Command	Usage(s)

Installation

The OTP application :ethereum_jsonrpc can be used in other umbrella OTP applications by adding ethereum_jsonrpc to your list of dependencies in mix.exs:

def deps do
  [
    {:ethereum_jsonrpc, in_umbrella: true}
  ]
end
