FAQ
How is the USDT transfer fee calculated?
A USDT transfer needs 65,000 energy when the receiver already holds USDT and 131,000 when it does not. Without energy the network burns 100 SUN of TRX for each missing unit; with rented energy you pay the rental price instead. The estimate multiplies the energy by the live price and adds the activation fee when the receiver is new.
What does “energy is lower than necessary” mean?
The sending account has less energy than the transfer needs, so the wallet either refuses or burns TRX for the difference. Check the sender's energy, then rent the amount the transfer needs and send it again.
Where does the address check get its numbers?
It reads the address straight from the TRON chain through our own node, with a short cache. It needs no sign-up. It does not report a USDT balance yet, so it cannot tell 65,000 from 131,000 energy on its own.
Are these numbers binding?
No. They are the published prices at the moment you look. A binding price comes from a quote, which holds for 120 seconds.
