rpc.txfeecap: Sets a cap on transaction fee (in ether) that can be sent via the RPC APIs (0 = no cap).
ipcdisable: Disable the IPC-RPC server.
ipcpath: Filename for IPC socket/pipe within the datadir (explicit paths escape it).
jsonrpc.corsdomain: Comma separated list of domains from which to accept cross.
jsonrpc.vhosts: Comma separated list of virtual hostnames from which to accept requests (server enforced). Accepts '*' wildcard.
http: Enable the HTTP-RPC server.
http.addr: HTTP-RPC server listening interface.
http.port: HTTP-RPC server listening port.
http.rpcprefix: HTTP path path prefix on which JSON-RPC is served. Use '/' to serve on all paths.
http.modules: API's offered over the HTTP-RPC interface.
ws: Enable the WS-RPC server.
ws.addr: WS-RPC server listening interface.
ws.port: WS-RPC server listening port.
ws.rpcprefix: HTTP path prefix on which JSON-RPC is served. Use '/' to serve on all paths.
ws.modules: API's offered over the WS-RPC interface.
graphql: Enable GraphQL on the HTTP-RPC server. Note that GraphQL can only be started if an HTTP server is started as well.
