JSON RPC
JSON RPC is available via HTTP and WS.
JSON RPC needs to be explicitly switched on in the Nethermind config file.

  "JsonRpc": {

    "Enabled": true,
3
    "Host": "127.0.0.1",

JSON RPC can be also enabled by passing --JsonRpc.Enabled true flag to the Nethermind.Runner or Nethermind.Launcher arguments.

WebSockets, when enabled, will be accessible on the same address/port as HTTP by default, just using the ws:// protocol instead of http:// protocol. You can change the WebSocket port to something else like 8546 if desired.

IPC communication over Unix Domian Socket can be enabled by providing a path to a socket file. This communication type works on all systems that implements the standard including Windows 10.
