# Does Wealify Wallet have an official currency?

At Wealify, all transactions within the platform are conducted using the official Wealify currency, called \[<mark style="background-color:orange;">**VNDW**</mark>].

VNDW is a currency that applies **TRC20** technology, which is a type of smart token standard used on the **TRON** blockchain network.

Any other currencies deposited into the Wealify system are converted to VNDW at the corresponding exchange rates. The current default exchange rate is 1 VNDW = 1 Vietnamese Dong (VND).

Wealify supports a variety of currencies for top-up and withdrawal, including Vietnamese Dong (VND), US Dollar (USD), Euro (EUR), British Pound (GBP), and Australian Dollar (AUD).

The specific currency options available for top-up and withdrawal will depend on the payment method selected by the customer.
