HOw do i make it only possible to buy kits with bank notes only?

You can do it through the Kits config.  

1.  In oxide/config/Kits.json (or carbon/config/Kits.json) set your only currency to the banknote item:
    

   "Economies": {
      "0": {
        "Type": "Item",
        "ShortName": "sticks",
        "Skin": 2536195910,
        "DisplayName": "Bank Note"
      }
    },
    "DefaultCurrency": 0

   
    
2.   In oxide/config/Kits.json (or carbon/config/Kits.json) set each purchasable kit to use that currency and a price, for example:
    

   "MyKit": {
      "Sale": true,
      "Price": 50,
      "DefaultCurrency": 0
    }

   
    
3.  Then save the files, reload the plugin (o.reload Kits / c.reload Kits), and test buying the kit with only those banknotes in your inventory.
