Energy per USDT transfer
Measured on the USDT contract, not taken from a table. The amount can change when the network adjusts the contract's energy factor.
The measured energy of a USDT transfer is not available right now. Nothing is shown rather than a guess — please try again in a few minutes.
Questions
How much is the TRC20 fee now?
The fee is the energy the transfer needs multiplied by the network's energy price, burned in TRX. The live figures are not available at this moment, so no number is shown.
Why two amounts?
The USDT contract keeps one balance entry per address. Sending to an address whose USDT balance is zero makes the contract create that entry, and writing a new storage entry costs more energy than changing an existing one. What counts is the balance at the time of the transfer: an address that once held USDT and is back at zero costs the higher amount again.
What is the dynamic energy model?
TRON raises the energy cost of contracts that use a large share of the network's resources. Such a contract carries an energy factor, and each call costs its base energy times one plus that factor. The USDT contract's factor currently makes a call cost 4.40 times its base energy. The factor is adjusted by the network every maintenance period, within limits set by chain parameters.
How is the energy measured?
By simulating a USDT transfer against the live contract without sending it — once to an address that holds USDT and once to one that does not. The simulation returns the energy the call would use, including the dynamic-energy surcharge.
