Recently, I noticed something interesting when transferring USDT (TRC20):
Every transaction on the TRON network consumes Energy, and if your Energy runs out, the system automatically burns your TRX to cover the fees.
Many people overlook this, so they end up spending 10–20 TRX per transfer — which adds up fast.
Later, I found that you can actually rent Energy instead of letting the system deduct TRX.
Basically, if you have enough Energy in advance, no TRX will be used for fees.
I tried it myself — around 2–4 TRX is enough for one transaction (even for activating a new wallet),
which cuts the cost by over 80% compared to paying 13–28 TRX each time.
It’s a fully automatic process and usually takes just a few seconds.
If you often send USDT on TRON, this method really helps reduce costs.
Wallets like imToken, TronLink, and TP Wallet all support this feature, so it’s easy to use.
In short, if your TRX keeps disappearing during transfers,
it’s worth learning how the Energy system and rental mechanism work — it can save you a lot in fees.
I came across more details about it on trx300.cc, if you’re curious.
