Frequently Asked Questions

1. Why did my USDT transfer cost 27 TRX?

Your address had no Energy and the USDT smart contract had to write new storage records for your address (which happens on the first transfer). The network burned your TRX to pay for that computation. See our article on USDT fees for the full breakdown of all four scenarios.

2. What is the difference between Energy and Bandwidth?

Bandwidth is consumed by every transaction and measures the size of transaction data in bytes. Energy is consumed only by smart contract execution and measures computation. A TRX transfer uses Bandwidth only; a USDT transfer uses both. Details: Energy and Bandwidth.

3. How much Energy does a USDT transfer need?

Approximately 65,000 Energy for the first USDT transfer from a given address, and about 31,000 for subsequent transfers. Approving a contract to spend your tokens also costs around 65,000 Energy. Exact values drift slightly over time — check a block explorer for live figures.

4. How do I get Energy?

Only two ways exist: stake TRX (roughly 3.6 Energy per day per 1 TRX staked at current parameters) and receive Energy as a staking reward, or let the network burn your TRX when you have none. There is no third source — anyone claiming otherwise is misleading you.

5. If I stake TRX for Energy, can I still spend that TRX?

No. Staked TRX is locked for the duration of your stake. You choose the lock period when staking; modern TRON supports flexible periods with a short unstaking delay (currently a few days). Plan your liquidity accordingly.

6. What happens if my transaction fails — do I get Bandwidth and Energy back?

No. Any transaction that gets included in a block consumes its resources, even if the smart contract call inside it reverted. This is common to virtually all blockchains.

7. Is it true that the first transfer from a new wallet is the most expensive?

Yes, effectively. The first TRC-20 transfer from a fresh address triggers the expensive storage-write path (~65,000 Energy instead of ~31,000). A common practice is to make a first small "activation" transfer before doing larger ones.

8. What is the "fee mode" in my wallet (sender pays vs recipient pays)?

Some wallets let the recipient cover the burn instead of the sender. Your transfer looks free, but the recipient receives less than the sent amount. Always agree on the mode with the recipient beforehand — especially when paying invoices where the exact amount matters.

9. Are "energy rental" services legitimate?

Some are legitimate businesses built on TRON's delegation mechanics; others are not. Apply the usual rules: prefer services with a public history and independent reviews, be cautious with anything that sounds too cheap, and never — under any circumstances — share your seed phrase or private keys with a third party. Signing any transaction you do not fully understand is risky regardless of the service involved.

10. Where can I check the exact current fee parameters?

The TRON block explorer TronScan displays live network parameters, including the Energy burn rate. Your wallet usually also shows the estimated fee on the confirmation screen before you send anything — read that screen carefully before confirming.

11. Does TRON "destroy" the burned TRX?

Yes. TRX burned for resource shortages is permanently removed from circulation. There is no way to get it back and no recipient — it is not a tip to validators.

12. Is TRON more expensive than other networks?

It depends entirely on whether you hold resources. With staked Energy a USDT transfer is effectively free; without it, the burn can look high compared to flat-fee chains. Understanding the resource model is what lets you stay on the cheap side of that line.
