Ultimate Guide to Saving Gas on TRON

Utilize "Energy Leasing + GasFree" to reduce transaction fees to a minimum.

If you often transfer $USDT on #TRON , mine #DeFi , or mint #NFT , you must have noticed that at the end of August, the unit price of Energy was adjusted from 0.00021 TRX to 0.0001 TRX. This is the largest fee reduction since the mainnet launch, and a quarterly dynamic pricing adjustment has been introduced—reviewed quarterly according to TRX prices and on-chain activity, ensuring it remains "easy to use and affordable" in the long term.

More importantly: JustLend DAO has made fee reduction a "ready-to-use" two-piece set:
(1) Energy Rental: Rent the energy generated by others' pledges on demand, saving 70%-80% of contract costs per transaction;
(2) GasFree Smart Wallet: Directly deduct transaction fees using transfer tokens (such as USDT), no need to stock up on TRX anymore.

The following explains clearly and succinctly why it is effective, how to use it, and how much can be saved when used to the fullest.

01｜First, understand the "Bandwidth + Energy" dual resources of TRON.

(1) Bandwidth: Basic resource that covers the storage and network usage of all transactions; regular TRX transfers, voting, staking, etc., only consume bandwidth. There is also 600 units of free bandwidth available daily, and if it's not enough, TRX can be staked to obtain more, or it can be directly purchased at 0.001 TRX/unit.

(2) Energy: Contract resource that is consumed only when triggering a smart contract (e.g., DeFi borrowing and lending, NFT minting, TRC-20 token transfers, etc.). The lower the unit price of energy, the lower the cost of using the DApp.

This model, which separates "simple transactions" from "complex contracts," allows TRON to have more controllable and predictable costs in high-frequency small-amount scenarios (stablecoin payments, GameFi, contract calls).

02 | Three Ways to Acquire Energy (Comparison at a Glance)

(1) Staking TRX: Daily energy allocation based on your share of the total network staking ratio (for example, 1 TRX ≈ 10 energy/day, subject to network fluctuations); suitable for long-term heavy users/projects.

(2) Burn TRX Direct Purchase: at the current unit price of 0.0001 TRX/energy; simple and straightforward, but the most expensive.

(3) Leasing Energy (Recommended): Temporarily using idle energy from others for a short term, no need for lock-up, lowest cost, and highest flexibility.

Why is it "the most economical to rent"?
You don't need to lock up TRX funds for a long time, only to pay for the contract calls for this moment/these few days; meanwhile, the lenders can monetize idle energy, creating a win-win market.

03 | Rent Energy with JustLend DAO: A Three-Step Process

Entrance: JustLend DAO → Energy Rental

Step 1. Fill in the parameters:
(1) Rental quantity: Minimum 100,000 energy (one TRC-20 USDT transfer ≈ 120,000 energy)
(2) Rental Duration: by hour/daily (1–30 days)
(3) Receiving address: can be your own or someone else's address (rental support available)

Step 2. Prepaid fees:
(1) Contains only three items: rent + deposit (returned at the end) + penalty for breach of contract (restrictive use), fully transparent with no hidden fees.
(2) Example: Rent 100,000 energy/1 day, prepay about 45.5 TRX (subject to the interface).

Step 3. Manage Orders:
(1) Support early termination of lease, renewal, viewing remaining energy and lease term.
(2) Tips: Make only one or two transactions, and withdraw immediately to avoid idle costs; frequent users are advised to rent for 30 days to dilute the cost per transaction.

Latest good news: After the energy unit price reduction, the "basic tax rate" for JustLend DAO leasing has decreased from 15% to 8%; currently at a price of about 26 SUN/day, 2.62 TRX can rent 100,000 energy (equivalent to the daily capacity of staking nearly 10,000 TRX).

Real Comparison (Common Scenario: Transfer 1 TRC-20 USDT)
(1) Directly burning TRX: Approximately $4.3 in energy costs
(2) Execution after leasing: about $1.17
👉 Save over $3 per transaction, with a reduction of >70%

04 | With GasFree: Instant transfers without holding TRX

What is GasFree?
(1) In one sentence: "Use the same currency to pay for whatever cryptocurrency you are converting."
(2) When you initiate a TRC-20 transfer in wallets like TronLink / imToken / Klever, the transaction fee is deducted directly from the transferred tokens (currently TRC-20 USDT is supported, and more assets/multi-chain are being expanded).

Why is it a "golden partner" with renting energy?
(1) Experience: Say goodbye to the multi-step process of "first exchange TRX → then transfer", and transfer with one click like sending a message;
(2) Cost: GasFree has a maximum fee subsidy of 90% during the launch period, with a single USDT transfer costing about $1;
(3) Universal: Extremely friendly to new users/enterprises - no need to hold native coins to complete payments and settlements.

Some data (as of 9/8):
(1) GasFree has a cumulative transaction value of approximately $15.8 billion, with over 750,000 transactions, saving users nearly $2.2 million in Gas.
(2) The developer center has been provided (energy cost prediction, automatic leasing, optimization suggestions, etc.), allowing project parties to "one-click access" more easily.

05｜Recommended Combinations and Savings List

(1) Small/low-frequency users: First check if the free bandwidth is sufficient; when a contract is needed → temporarily rent 100,000 to 200,000 energy → transfer directly using GasFree.

(2) Medium to high frequency individuals/quantitative: Rent stacking GasFree for 7-30 days, long-term diluted to about $1 per transaction.

(3) Team/Project Party: Integrate energy leasing + GasFree interface into the product flow, optimizing experience while stabilizing costs; TRX only needs to maintain operational support.

Practical Points
(1) USDT single transaction ≈ 120,000 energy, be sure to match as needed, do not rent more.
(2) Return it after use to avoid idleness.
(3) The dynamic unit price and rental tax rate will be adjusted; it's best to check the panel before placing an order.

Conclusion: Achieving "affordable, user-friendly, and predictable" to the fullest.

The reason why #TRON can achieve scale in the stablecoin and daily payment scenarios is that this combination of resource model + market-based leasing + experience layer abstraction is a significant factor:
(1) Protocol Side: Bandwidth/Energy Divisional Control + Seasonal Pricing, anchoring costs to real demand;
(2) Market Side: JustLend DAO turns "energy" into a rentable infrastructure;
(3) Application Side: GasFree allows users to no longer be burdened by native coins.

The result is: the cost per transaction has significantly decreased, the experience has been greatly simplified, and the development integration is also lighter. If your product or daily operations run on TRON, this set of "energy leasing + GasFree" is almost a must-have money-saving shortcut.
