# Your payment system

### **Description**

The balance of your system is a full-fledged payment system.

You can add additional balance currencies.

All balance payment systems support their own API. More details in the section [Training - Your API](https://doc.money-top.com/en/other/training/your-api)

### **Settings**

To add a new currency, you need to add a payment system with the desired currency and the "balance" API. You cannot add multiple identical balance currencies.

To change the base currency of the site, you now need to change the currency of the system payment system "balans" (by default VU-Money USD).

Changing the balance currency does not recalculate current user balances at any rates. Check user balances before changing currencies.

All additional user balances will be visually converted and added up to the total balance in the system currency.

For conversion, the rates indicated in the directions between the payment systems of these balances will be used.

The best solution would be to install a rate source between all balance payment systems so that the rates are always up to date.

Be sure to monitor the rates between the balance payment system and all others (even if these directions are disabled). These courses are used in the affiliate program and your API.

Deleting a payment system balance will also delete all user balances in that currency. Check user balances before deleting.

To work correctly with the API, you need to specify the “System Code” for your balance payment systems. You can come up with your own, but do not use existing codes from other PS.

The name of the balance can be changed from “Balance” to any other in the main site configuration: “Balance name”.

Only system currency is used for deposits

Investment plans can be created in any balance currency

Internal transfers between users are available for each created currency
