Quick answer is No.
Every time you send any stable coin from one address to another, you incur a transaction fee — also called a network fee. This fee is charged by the sending platform, not Cardtonic. This fee is not included in the total amount shown to you because it varies by sending platform and the how fast you want the transaction.
It is like a transfer fee when you transfer money between bank accounts, the higher the network fee you use when sending, the faster the transaction will be completed.
We would advise you to use adequate network fees when funding your card with stable coins to avoid delay.
