JustLend DAO has added a Buy Energy feature to its TRON-based services, offering one-hour resource purchases for smart-contract transactions at an estimated cost roughly 64% below the price of acquiring the same Energy by burning TRX, according to the platform’s Aug. 20 announcement. The tool gives users a short-duration alternative to staking TRX, renting Energy, or paying network resource costs directly through token burns.
The new service is designed for users who need Energy immediately for a limited number of transactions, including TRC-20 token transfers, decentralized finance interactions, and batch payments. Purchased Energy expires automatically after one hour, removing the deposit and settlement process used by longer-term rentals. A single order can send Energy to as many as 50 TRON addresses, with confirmation typically taking about 10 seconds, JustLend DAO said.
TRON’s resource model separates Bandwidth from Energy. Every account receives 600 units of free Bandwidth each day for basic network activity, after which users pay 0.001 TRX per unit, according to TRON documentation. Energy is required for smart-contract execution and carries no daily free allocation. Users can obtain it by staking TRX, burning TRX, or using services such as JustLend DAO’s rental and purchase products.
For a USDT transfer requiring 65,000 units of Energy, JustLend DAO’s example puts the direct burn cost at about 6.5 TRX. Buying the same amount through the new feature costs about 2.34 TRX, a difference of approximately 64%. A separate example cited a 6.2371 TRX cost, or $2.092, for a transfer paid through TRX burning, compared with 1.0076 TRX, or $0.338, after buying Energy. That calculation represents an estimated saving of about 84%, though the dollar value changes with TRX’s market price.
a third option for tron transaction costs
Buy Energy joins JustLend DAO’s existing Energy Rental service and TRON’s GasFree transfer system. The three services address different transaction patterns: GasFree allows certain token transfers without holding TRX; Buy Energy targets immediate, short-lived demand; and Energy Rental is built for users needing resources over hours or days.
Energy Rental, introduced in 2023, lets users rent Energy for periods ranging from one hour to 30 days. It allows Energy to be sent to another address and includes a mechanism that returns remaining rental value when unused resources are settled.
JustLend DAO data dated Aug. 27 showed its rental service had more than 82,300 cumulative users and averaged nearly 48 billion units of Energy output per day. The same data recorded a single-day peak above 16 billion units and listed a daily price of 40 sun, the smallest denomination of TRX, though rental pricing can vary with utilization.
In one rental example provided by JustLend DAO, 100,000 units of Energy cost 4.03 TRX and was described as roughly equivalent to the Energy produced by staking about 10,450 TRX. The platform said that amount could cover two contract transactions. Burning TRX to obtain 100,000 units of Energy would cost 10 TRX under the example’s assumptions.
The cost difference is especially pronounced in the platform’s USDT transfer estimates. JustLend DAO listed a transfer cost of about $2.092 when Energy is covered through burning TRX, compared with $0.115 through rented Energy, an estimated reduction of more than 94.5%. The comparison depends on prevailing TRX prices, the Energy required by a transaction, and rental-market conditions.
gasfree targets users without trx
GasFree, launched in March 2025, takes a different approach by allowing users to pay a transfer fee in the token they are sending. The service currently supports USDT and USDD, eliminating the need for a sender to acquire TRX solely to complete an eligible transfer.
According to the figures supplied by JustLend DAO for Aug. 26, GasFree had processed more than $130.5 billion in cumulative transfer volume across more than 7.58 million transactions. The service had saved users $8.4 million in fees, the platform said.
Its fee schedule was adjusted in June 2025, when USDT address activation and transfer charges were set at 1.5 USDT. USDD was added in August 2025 with a one-time activation fee of 1 USDD and a 0.5 USDD fee for each transfer. Once an address has been activated, it can use both USDT and USDD without paying another activation charge, according to the service’s terms.
GasFree fees do not vary by transfer size. Under the stated schedule, sending 100 USDT and sending 100,000 USDT would incur the same transfer fee. That structure can be useful for larger transfers, while users making frequent smart-contract calls may find rentals or purchased Energy more relevant because GasFree is limited to supported token transfers.
lower base burn rates reshape comparisons
TRON reduced its Energy burn price in August 2025 from 0.0021 TRX per unit to 0.0001 TRX per unit, according to network pricing information cited in the supplied material. The change was a reduction of about 95.2%, rather than merely more than 50%, and lowered the baseline cost of paying for smart-contract resources through TRX burns.
Even after that cut, the cost of burning TRX remains sensitive to the token’s market price. A transaction’s Energy requirement may be fixed or predictable, but its dollar cost rises and falls with TRX. Rental and purchase services introduce their own variable pricing, based on utilization and service terms, yet give users a quoted resource cost before a transaction is submitted.
The resulting choice is increasingly practical rather than ideological. A user sending USDT without TRX can use GasFree. A wallet operator preparing a brief batch of transactions can buy one-hour Energy for several addresses. A decentralized application, payment service, or automated system with recurring contract activity may prefer rental terms that extend to 30 days.
JustLend DAO’s new product therefore places an additional pricing layer between TRON users and direct resource burns. Its usefulness will depend on whether quoted purchase rates remain below direct burn costs during periods of elevated network activity, when resource demand and transaction volumes can change the economics of each option.
