The procedure for exchanging Tether in the TRC20 network to Visa Mastercard in PLN currency begins with creating a request in the selected exchanger. The user specifies the exact amount, receives a unique address, and sends USDT from their cryptocurrency wallet. After confirmation by the blockchain, the corresponding exchange transaction is formed, and the service proceeds to internal settlement. The TRC20 network provides stable transfer processing, which speeds up the overall process. After receiving Tether, the digital asset is converted into its fiat equivalent and a payment to Visa Mastercard is initiated. The funds are credited to a card issued by a Polish bank and displayed on the customer's balance in PLN. When choosing an exchange service, it is necessary to take into account the possible commission, the established limit, and the total amount of the exchange transaction. A reliable service fixes the terms of the transaction in advance, ensuring transparent calculation of the final amount.
