Why is there a network fee?

A fee pays for transaction processing on the selected network.

I have the token, but cannot send it

Some networks charge fees in their native coin, separately from the token being sent. A USDT balance alone therefore does not guarantee you can send it. Check the required resource and the error message for the selected network.

What the dollar amount means

A dollar estimate uses a market rate and can change without any coin transfer. The exact asset amount and fee are expressed in network units. If a price is unavailable, check the coin quantity itself.

Service fees

A purchase or swap provider may charge a separate service fee. Compare it with the network fee and total amount. An integration under development does not establish that real purchases are available in the current release.
