If you encounter payment failures, expired addresses, or are unsure about the USDT network, check this page first.
Check your balance, network connection, and whether the payment address is correct. If it continues to fail, contact support.
Do not pay again. Save your payment screenshot and order number. Check the Order Lookup page later, or contact support for manual verification.
Please contact support immediately with your order number, payment screenshot, and actual payment amount. Wait for manual processing.
Do not continue transferring. Contact support first. If already sent, recovery depends on the receiving platform and on-chain status.
