What is WXT in Wirex?

Could you elaborate on the concept of WXT in the context of Wirex? I'm curious to understand its significance and role within the platform. How is it different from other cryptocurrencies, and what are the benefits or advantages that users can gain by utilizing WXT within Wirex? I'm also interested in knowing whether there are any specific features or services that are exclusively accessible through WXT, and how the adoption of WXT could potentially impact the overall user experience on Wirex.
