USDT help
This guide focuses only on amount mismatch. Do not guess how much to add, do not pay expired orders, and do not create duplicate orders to offset a difference.

When the USDT amount does not match the order, automatic matching may fail. Underpayment, overpayment, exchange fees, and late extra transfers should be reviewed with order number and TxID.
The order amount helps match one blockchain payment to one top-up order. A rounded, estimated, lower, or higher amount can break matching.
Underpayment may leave the order unmatched or require manual review. Even a small shortage should not be assumed to complete automatically.
Overpayment does not automatically upgrade the product and does not guarantee immediate return of the extra amount. Handling depends on review results.
Some wallets or exchanges deduct fees. The amount you intended to send may differ from the amount actually received by the payment address.
An extra transfer can create a second mismatch. Multiple orders do not automatically offset one underpaid or overpaid order.
Manual review may take time. Extra amount, shortage handling, or balance treatment depends on the final audit result and order record.
Compare required order amount with actual sent amount.
Check whether wallet or exchange fees changed the received amount.
Save order number, TxID, network, and amount screenshots.
Do not send a guessed second payment or create duplicate orders.
Contact support and wait for review.
