Dear Valued Users,

As USD1 is an asset issued by the WLFI project team, and in order to mitigate potential risks, safeguard user assets, and maintain a fair trading environment, HTX will delist USD1 at 03:00 (UTC) on June 7, 2026. Eligible USD1 holdings in user accounts will be converted to USDT at a 1:1 ratio.

Upon completion of the conversion, the corresponding USDT will be credited to users' Spot Accounts. The exact completion time and distribution details will be announced separately.

Please note:

• After USD1 deposits are suspended, deposit and conversion services for USD1 will no longer be supported;
• Following the delisting of USD1, eligible USD1 assets will be transferred to users' Spot Accounts and converted to USDT at a 1:1 ratio;
• The specific conversion completion time and asset distribution results will be announced separately in a follow-up notice.

Thank you for your support!

HTX
