Service Maintenance Notice 📢
Dear Users,
To provide you with a better service experience, QIXIN will perform a system maintenance and upgrade on April 20, 2026, from 02:00 to 06:00 (New York Time). During this period, services will be temporarily unavailable. We sincerely apologize for any inconvenience caused.
This DFirstCoder App Version 1.6.2 update mainly includes the following improvements:
•More detailed regional segmentation in the DFirstCoder App
For an improved user experience, please update your app to version 1.6.2 after the maintenance and select your corresponding region.
•QD exchange rate optimization
To unify global pricing standards, the QD exchange rate will be adjusted from 1:10 to 1:70.
For example:
•Before: 1 USD = 10 QD
•After: 1 USD = 70 QD
This change will take effect immediately after the maintenance. To protect user rights, the system will automatically convert any unused QD in your account at the new rate (1 USD = 70 QD). Your total usable QD value will remain unchanged after the conversion. Please note that already consumed QD will not be included in this adjustment.
After the maintenance, if you encounter any issues, please feel free to contact our support team. We will respond as soon as possible.
Thank you for your understanding and support.
QIXIN OBD TEAM.
