Can this plugin use ServerRewards ( RP ) instead of Economics ?

Hi! Yes, ofc

Example for ServerRewards:
 

  "Economy": {
    "Type (Plugin/Item)": "Plugin",
    "Plugin name": "ServerRewards",
    "Balance add hook": "AddPoints",
    "Balance remove hook": "TakePoints",
    "Balance show hook": "CheckPoints",
    "ShortName": "scrap",
    "Display Name (empty - default)": "",
    "Skin": 0
  },

Changed Status from Pending to Closed
