02 · EARNING PLANS

Review the terms before choosing

  1. Compare Energy Plan No. 1 and Bandwidth Plan No. 1.
  2. Check amounts, reward calculation, settlement, fees and redemption timing.
  3. Read wallet signing details and distinguish delegation, token approvals and transfers.
  4. Save the order ID and transaction hash, then verify status and settlement.

03 · ENERGY RENTAL

Prepare resources for a transfer

  1. Confirm the sender and TRON network; review Energy and Bandwidth.
  2. Use a live transaction estimate to compare resources, duration and cost.
  3. Verify resources reached the correct address before making the transfer.
  4. Check the resource order and the actual transfer separately.

04 · USDT / TRX SWAPS

Check the amount and network

  1. Verify assets, direction and receiving network.
  2. Check the quote, fees, expected amount and quote expiry.
  3. Verify the address and what the wallet signature authorizes.
  4. Save order and transaction references; check pending status before retrying.
05 · SMART COUNT

Estimate how many transfers your resources cover

  1. Smart Count is an OPO product concept, not a separate TRON resource.
  2. Check supported transactions, address conditions and validity.
  3. Use current app estimates; contracts and network conditions affect usage.
  4. Review usage and remaining allowance; actual on-chain resource use determines the final amount.
06 · TROUBLESHOOTING

An order is not the same as a transfer

  1. Order IDs identify platform orders; transaction hashes identify on-chain transactions.
  2. Verify network, addresses, time and execution results for each transaction.
  3. For pending or failed actions, check the reason and charged fees before retrying.
  4. Use official contact links and provide only necessary order details, never wallet secrets.

Questions worth clearing up

Do TRX and USDT transfers use the same resources?+

Ordinary TRX transfers mainly use Bandwidth. TRC-20 USDT transfers call a contract and usually also use Energy. Use a current estimate.

Do resources recover?+

Network resources recover gradually under network rules, rather than resetting at midnight. Rental validity is governed separately by the order.

How do staking, delegation and voting differ?+

Staking obtains resources and voting power; delegation lets another address use resources; voting participates in Super Representative elections. Resource and voting rewards have different sources.

Is redemption instant?+

Product redemption, ending delegation and unstaking are different steps. Stake 2.0 unstaking has a network waiting period. Check app terms and on-chain withdrawal availability.

Can the No. 1 annual rate change?+

Energy Plan No. 1 and Bandwidth Plan No. 1 each have a fixed annual rate of 18.25%. OPO calculates rewards for the actual delegation duration and pays them hourly. Future No. 2 or No. 3 plans may offer different rates; that does not change the No. 1 rate. Your payout also depends on the eligible amount and duration, so a fixed rate does not mean an identical payout every day.

Are check-in rewards the same as Smart Count?+

Check reward assets, operation allowances, permitted use and expiry separately in the activity rules and claim records.

TRON resource basics
01

What is Energy?

Energy covers smart-contract computation. TRC-20 transfers, swaps and DApp activity commonly consume it.

02

What is Bandwidth?

Bandwidth covers transaction data size; non-query transactions generally consume it.

03

When resources run short

The network may burn TRX from the sender according to current chain parameters.

04

Staking and delegation

Staking obtains resources; resource usage can be delegated while the underlying TRX stays with its owner.

Four checks before acting

A live estimate is safer than memorizing fixed values.

  1. 01Check wallet resources
  2. 02Confirm transaction and contract type
  3. 03Review the live Energy estimate
  4. 04Verify the address before confirming

TRX and USDT basics
START WITH THE BASICS

TRX, USDT and resources: what’s the difference?

TRX

TRX is TRON’s native asset. Staking can provide resources; when resources are insufficient, the network may burn TRX to cover costs.

USDT · TRC-20

USDT on TRON is a token, not TRX. Sending it calls a token contract, so Energy and Bandwidth matter. A USDT balance does not mean you have enough network resources.

Why estimate first?

Resource use depends on the operation and contract state. Check the wallet’s current estimate rather than copying someone else’s transaction cost, then compare your resources and rental options.
