Transferring USDT (TRC20) on TRON is essentially a smart-contract call, which consumes energy.
How much does one transfer need?
- A regular TRC20 USDT transfer consumes about 65,000 energy (per live network parameters; may vary slightly)
- It also uses a little bandwidth (usually covered by the free quota, or the wallet auto-burns TRX)
What if there's not enough energy?
- Error: OUT OF ENERGY
- If the wallet has TRX, the network auto-burns TRX as the fee — the very money you're trying to save
How much should you rent?
- One transfer: rent 65,000 energy to start
- Multiple / high frequency: rent more (e.g., 131,000) and pick a longer duration
- Not sure? Rent 65,000 first, wait for delivery, then send a test transfer
Tips
- Before the first transfer, confirm energy is delivered (order status "Completed")
- For high-frequency receiving addresses, long-term rental costs far less than burning TRX every time
