Yes. Any transaction carried out on the TRON network, such as external withdrawals, requires the sending address to have a balance of TRX to cover network fees.
On most networks, BIX covers the transaction costs and fees. However, this does not apply to the TRON network. For this reason, the address must have sufficient TRX to process the transaction.
If you plan to make deposits or withdrawals using the TRON network, keep this requirement in mind and ensure you maintain an adequate TRX balance to prevent the transaction from failing.
