Manage TRON Energy for Cheap Transfers
TRC-20 transfers burn TRX unless the sender holds energy. This guide provisions energy by staking, delegating or renting so USDT transfers run cheaply. Provision energy ahead of sweeps and payouts to keep per-transfer cost predictable.

1Estimate the energy a transfer needs
A standard USDT transfer costs roughly 32,000 energy; a first transfer to a fresh recipient costs more. Size your rent to the batch.
2Rent energy to the sender
Call /v1/tron/energy/rent with the receiver and the energy amount. Renting is the fastest path when you need energy only for a run.
curl -X POST https://api.1st-node.com/v1/tron/energy/rent \
-H "Authorization: Bearer sk_live_..." \
-d '{"receiver":"TTreas...","amount":32000}'
> {"status":"active","energy":32000,"expires_at":"2026-07-04T11:00:00Z"}3Or stake and delegate for standing capacity
For steady volume, stake TRX and delegate the resulting energy to your senders so you stop paying per rent.
curl -X POST https://api.1st-node.com/v1/tron/energy/stake \
-H "Authorization: Bearer sk_live_..." \
-d '{"receiver":"TTreas...","amount":128000}'
> {"status":"staked","energy":128000}4Verify before sending
Simulate the transfer to confirm the energy budget is met, then broadcast. A short energy budget shows up as a revert reason.
Perguntas frequentes
Rent, stake or delegate — which do I use?
Rent for one-off runs, stake for standing capacity, delegate to move staked energy onto specific senders. All three cut TRC-20 transfer cost versus burning TRX.
How much energy does a USDT transfer need?
About 32,000 energy for a normal transfer, more when the recipient has no prior USDT balance. Size rented or delegated energy to the batch.
