WCT Payment Function's Automatic Exchange Service Test**
The WCT payment test adds an automatic exchange service, allowing users to pay with other tokens (such as ETH, USDT), and the system automatically exchanges them for WCT at the real-time exchange rate for settlement, with an exchange fee of 0.5%. Testing shows that automatic exchange increases the payment success rate to 95%, and the willingness to use it among non-WCT holders has increased by 40%. The service addresses the user pain point of "unable to pay without WCT," expands the audience for the payment function, and brings more potential holders to WCT.
