Place Order

info

• Orders are processed asynchronously. A successful response means the order was accepted, not that it has been settled. Use Get Order List to track order status.
• orderLinkId provides idempotency — submitting the same orderLinkId returns the same orderId without creating a duplicate order.
• Mint: Transfers USDT from your Flexible Saving account to mint byUSDT.
• Redeem: Burns byUSDT and returns USDT to your Unified Trading Account (UTA).
