Frequently Asked Questions
Everything you need to know about TRON Energy, Bandwidth, SUN, and how to save up to 90% on network fees.
TRON is a public blockchain designed for fast, high-throughput transactions. Every operation on the network — sending USDT (TRC-20), interacting with smart contracts, DeFi swaps — has a cost paid through two resources: Energy and Bandwidth.
If you don't have enough resources available, the network automatically burns TRX directly from your balance at a fixed rate, which can be significantly more expensive than renting.
SUN is the smallest unit of TRX, analogous to Satoshi for Bitcoin or Wei for Ethereum.
Energy and Bandwidth rental prices are quoted in SUN per unit per day. For example, a rate of 100 SUN/Energy/day means renting 1,000,000 Energy for 1 day costs 100 TRX. Understanding SUN is key to comparing offers correctly.
Energy is the resource consumed every time a smart contract executes on the TRON network. Each computational step requires a certain amount of Energy.
| Operation | Typical Energy |
|---|---|
| USDT transfer (TRC-20) — active wallet | ~13,000 – 15,000 |
| USDT transfer — new/unactivated wallet | ~27,000 – 32,000 |
| DEX swap (SunSwap / JustSwap) | ~40,000 – 80,000 |
| Complex DeFi interaction | 80,000 – 150,000+ |
Without Energy, the TRON network burns TRX at the fixed rate of 210 SUN per unit of Energy directly from your balance.
Compare this to renting 65,000 Energy at market rate (~85 SUN/day): the total cost is roughly 5–6 TRX — a saving of 60–80%.
There are three main ways:
1. Rent from an Energy Pool — pay a small amount of TRX to a pool that temporarily delegates Energy to your wallet. Prices typically range between 80 and 130 SUN/Energy/day. Ideal for occasional or one-time use — no locking of capital required.
2. Freeze TRX (Stake) — lock TRX via the TRON network to receive Energy proportional to the staked amount. Energy regenerates every 24 hours. Best for users who transact very frequently and want zero marginal cost per transaction.
3. Receive delegation — some exchanges and services delegate Energy to active users automatically.
Bandwidth (also called "Net") covers the byte size of each transaction on the blockchain. Unlike Energy — which is only consumed by smart contracts — Bandwidth is used by every transaction, including simple TRX transfers.
| Operation | Typical Bandwidth |
|---|---|
| TRX transfer | ~268 units |
| TRC-20 transfer (USDT) | ~345 units |
| Smart contract interaction | ~400 – 600 units |
Without Bandwidth, the network charges 1,000 SUN (0.001 TRX) per unit consumed, deducted directly from your TRX balance. For occasional users, the daily free allowance is usually sufficient. It becomes relevant for:
- High-volume traders or bots executing dozens of transactions per day
- Exchange hot wallets processing large volumes
- DeFi protocols making frequent on-chain state changes
Bandwidth can be rented from the same pools that offer Energy — search on TronScan.energy →
An Energy Pool is a marketplace where users who have staked TRX (and therefore generate surplus Energy) can rent it out to those who need it, in exchange for a TRX payment.
It works as a peer-to-peer market:
- Sellers — stake TRX, generate Energy, list it on the market and earn an average APY of 15–27%.
- Buyers — pay a small TRX fee to receive Energy delegated directly to their wallet for a chosen duration.
The delegation is native to the TRON blockchain — no custody, no private key sharing required.
1. Decide how much Energy you need (e.g. 65,000 for a safe USDT transfer) and for how long.
2. Find the best price via TronScan.energy and click the link to the provider.
3. Enter your TRON wallet address and complete the TRX payment on the provider's site.
4. Energy is delegated to your address within seconds.
5. Execute your transactions. When the rental expires, the delegation is revoked automatically — no action needed.
| Duration | Best for |
|---|---|
| 10 minutes / 1 hour | A single urgent transaction |
| 3 hours / 6 hours | A trading session or batch of transactions |
| 3 days | Ongoing DeFi activity |
| 30 days | Professional / continuous use — best per-day rate |
The savings are substantial. Example for a USDT transfer using 65,000 Energy:
| Method | Rate | Cost (TRX) |
|---|---|---|
| No Energy — direct burning | 210 SUN/unit | ~13.65 TRX |
| Pool rental (1h, best rate) | ~80–90 SUN/unit/day | ~0.5–1.5 TRX |
| Pool rental (30 days) | ~60–75 SUN/unit/day | ~0.3–0.8 TRX |

Yes — the delegation mechanism is native to the TRON protocol and does not require sharing your private key or seed phrase. The pool receives your TRX payment and in return delegates Energy to your address via an on-chain transaction you can verify.
That said, as with any third-party crypto service:
- Start with a small amount to get familiar with the process
- Always verify the URL of the provider before making a payment
- Never share your seed phrase or private keys with anyone
- Use only the direct links provided by TronScan.energy
TronScan.energy connects to the APIs of all major Energy Pools and fetches prices automatically, updated 4–6 times per day for flex/variable rates and every 5 minutes for sell-side market offers.
To compare: select the resource type (Energy or Bandwidth), the quantity you need, and the rental duration. Results are sorted from cheapest to most expensive, showing the total cost in TRX and the normalized unit price in SUN per day.
It's the normalized unit price that makes offers with different durations directly comparable.
Example: 65,000 Energy × 85 SUN/day × 1 day = 5,525,000 SUN = 5.525 TRX
A 30-day offer at 65 SUN/day is cheaper per day than a 1-hour offer at 90 SUN/day — the SUN/unit/day metric lets you see this immediately.
TronScan.energy shows you real-time sell opportunities across all pools — rates, durations, available quantities, and projected APY — so you can identify the most profitable market to offer your Energy on.
To list your Energy for sale, you register directly on the individual pool platforms (Tronify, TronPulse, Feee.io, etc.). TronScan.energy gives you the market intelligence to choose where to list and at what rate.
