What It Is
Energy is a TRON network resource. Transactions that run a smart contract — a USDT transfer, for example — consume Energy. If your account has none, the network burns TRX instead, so the same transfer costs you real money.
You get Energy by staking TRX. When you stake TRX from your Bron workspace, the TRON protocol allocates Energy to your address, and the stake may also be eligible for protocol staking rewards. Your Energy balance is shown on the TRON asset page, under Staking → Energy.
You can do two things with that Energy:
Keep it — your TRON transactions consume Energy instead of burning TRX.
Stake (delegate) it — delegate the Energy to TransaTron, which rents it to other TRON users who spend it. TransaTron pays you a rental fee in TRX. Your TRX stays staked at your own address throughout.
Energy delegation is offered by TransaTron, an independent third party. The transaction is prepared by P2P.org; you review and sign it yourself. Bron is not a party to your arrangement with TransaTron and does not set the rate or make payments.
Mobile. Everything starts with a TRX stake — the preview shows the estimated staking rate and the Energy the stake will generate.
Where to Find It
Energy lives on the TRON (TRX) asset page, in the Staking section. The Energy card shows your Available and Staked Energy and the Stake button.
If your Energy balance is 0, stake TRX first — Energy comes from the TRX stake. See Staking.
Desktop/Web
1. Open the TRON (TRX) asset page in your workspace.
2. Scroll to the Staking section.
3. Use the Stake button on the Energy card.
Desktop. The Energy card sits under Staking on the TRON asset page, with your Available and Staked Energy and the Stake button.
Mobile
1. On the dashboard, open TRON from the token list. To stake TRX first, tap More in the row of action buttons and then Earn, or use Stake on the TRON asset page.
2. Scroll down to the Staking section.
3. Tap Stake on the Energy card.
Mobile. On the dashboard, More opens Earn — the route to staking TRX. The token list below takes you straight to the TRON asset page.
Mobile. The TRON asset page: Stake among the action buttons, and the Staking section starting underneath.
Mobile. Scroll to Energy — 32 Energy available, none staked yet — and tap Stake.
How to Stake Energy
On the Energy card, tap or click Stake.
Enter the amount. You enter it in TRX and the screen shows how much Energy that TRX produces. Use the 25%, 50%, 75% or Max presets to fill it from your staked TRX. The minimum is 1 TRX.
Check the estimated rate and Lock period, then continue to the confirmation screen.
Review the Energy amount, the TRX behind it, the provider, the account and the network, then confirm.
Sign the transaction in the Bron Desktop App.
Mobile. Enter the amount in TRX — the line underneath converts it into Energy. The presets fill it from your staked TRX.
Desktop. The same form in one view: amount, the Energy it produces, the estimated rate and the 24-hour lock, then Preview.
Desktop. The stake lands in your transactions as a Stake deposit plus a Lock, and waits for your signature.
The transaction appears in your history as Stake, with a Stake deposit and a Lock step. Once it is confirmed, the Energy card moves the amount from Available to Staked and shows the date and time the lock ends.
Mobile. After confirmation: the Energy is delegated and locked until a set time, and the Rewards card is marked Earning with Energy.
Staking and unstaking Energy are ordinary TRON transactions and cost about 0.3 TRX each. If your account has spare Energy, the network spends that first, exactly as it does for a normal TRX transfer.
If you have just staked TRX and the form says there is not enough delegatable Energy, wait about a minute — the provider needs time to see the new stake.
⚠️ Staked Energy is locked for 24 hours. You cannot unstake it during this period.
Rental Payments
TransaTron pays the rental fee in TRX — ordinary TRX in your account, which you can send, swap or stake again like any other balance. You are not paid in Energy.
The rental fee is separate from any protocol staking rewards on the underlying TRX. The app shows TransaTron's current estimated rental rate (APR) when you stake. The rate is set by TransaTron, varies with demand for Energy on the network, and is not guaranteed.
TransaTron sends payments to your account directly; there is nothing to claim. It only sends a payment once the amount owed to you reaches 100 TRX, so on a small delegation the first payment can take a long time. Until paid, that amount is owed to you by TransaTron, not Bron. The Energy line on the Rewards card shows what has already been paid, not what is still accruing.
The Rewards card lists staking rewards and Energy rental payments as two separate lines with a combined total, so you can see which part came from where. On mobile, open Show breakdown to see them.
Unstaking Energy
After the 24-hour lock ends, open the Energy card and choose Unstake Energy. It takes effect immediately. While the lock is active, the card shows the date and time it ends.
The Energy comes back spent: whoever rented it has used it, and TRON regenerates Energy over about 24 hours. So you cannot stake it again or spend it on your own transactions right away — wait a day for it to build back up.
You do not have to wait for that to unstake your TRX. Unstake the Energy, then start the TRX unstake straight away — TRON's own 14-day waiting period on the TRX runs from that moment.
Using Energy Instead of Staking It
You do not have to stake Energy. Energy sitting in your Available balance is used automatically by the network when you send a TRON transaction, which lowers what you pay in TRX.
Staked Energy is not yours to use — that is the whole point of renting it out: someone else spends it. For an account that sends USDT on TRON regularly, keeping the Energy can be worth more than the rental fee.
If you have no Energy and no TRX for the fee at all, see Power Bank.
⚠️ Network fees apply when staking and unstaking Energy.
Rental fees and staking rewards are variable and depend on network conditions and demand for Energy. Past rates are not indicative of future rates. Bron does not guarantee any rate or payment.
Bron is a self-custodial software interface. Bron does not operate as a staking service provider, broker, exchange, dealer, market maker, or custodian, and does not hold, manage, or control user assets at any time. Staking and Energy delegation are provided by independent third parties (TransaTron and P2P.org); Bron does not control, audit, or guarantee their performance.
