JSON RPC

JSON RPC is available via HTTP and WS.
JSON RPC needs to be explicitly switched on in the Netherming config file.
goerli.cfg
  "JsonRpc": {
    "Enabled": true,
    "Host": "127.0.0.1",
    "Port": 8545
  }
JSON RPC can be also enabled by passing --JsonRpc.Enabled true flag to the Nethermind.Runner or Nethermind.Launcher arguments.
Nethermind.Runner
Nethermind.Launcher
./Nethermind.Runner --JsonRpc.Enabled true
./Nethermind.Launcher --JsonRpc.Enabled true
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.
goerli.cfg
Nethermind.Runner
Nethermind.Launcher
  "Init": {
    "WebSocketsEnabled": true
  },
  "JsonRpc": {
    "WebSocketsPort": 8545
  }
./Nethermind.Runner --Init.WebSocketsEnabled true --JsonRpc.WebSocketsPort 8545
./Nethermind.Launcher --Init.WebSocketsEnabled true --JsonRpc.WebSocketsPort 8545
Some of the methods listed in this section are not implemented by Nethermind (they will be marked).
