GasFree vs 能量租赁：2025 年该如何选择？

The Tron blockchain is a very flexible cryptocurrency eco-platform that provides users with choices in transaction payment methods.
Even when interacting with simple transfers in TRC-10 tokens, you can choose: use TRX or Bandwidth for fee payment.

But Tron offers even more choice to users who interact with smart contracts.
For example, to pay fees for transferring USDT TRC-20, you can now choose the following options:

• only native TRX crypto;
• special resources Energy and Bandwidth + TRX (burned if resources are insufficient);
• only Energy and Bandwidth, if sufficient;
• completely gas-free transaction via the GasFree function — payment in USDT stablecoins.

Much has already been written about ways to minimize expenses by using special resources instead of native crypto,
and active users know that using Energy to pay for transactions is much more advantageous than burning TRX.
This is because Energy can be obtained as a reward for staking a substantial volume of TRX
or, much more conveniently and almost as profitably — renting Energy on special services.

在后一种情况下，使用像NETTS这样的服务支付USDT TRC-20转账的费用可节省高达80%。

最近，Tron的另一项创新引起了轰动：使用GasFree功能，用户可以免除使用gas（Energy，Bandwidth和TRX）来支付USDT TRC-20转账手续费。

也就是说，在2025年，参与USDT稳定币转账的生态平台用户可以选择GasFree和能量租赁来支付这些转账交易费用。

哪个选项更好？让我们深入了解细节。

GasFree的工作原理？

GasFree 是一种允许用户发送交易而无需消耗 TRX、Energy 和 Bandwidth 的机制。 The actual commission costs are passed on to the smart contract sponsor (service provider).
Essentially, these are meta-transactions in the Tron ecosystem.

1. The user sends a transfer request (in USDT or another TRC-20 token) through a GasFree smart contract.
2. The smart contract (sponsor) pays the system costs (TRX, Energy, Bandwidth).
3. The user compensates the sponsor for the costs — pays the commission in another token (usually USDT).

This approach simplifies work for users who do not want to complicate their wallet balance with different assets and special resources.
GasFree allows sending USDT TRC-20 without TRX on the balance.

However, the price of such "compensation" can differ significantly from Tron network fees in native crypto and resources.
Because GasFree does not allow transactions with zero commission, but only shifts the commission from TRX to another token.

GasFree 的优势

完全无需TRX，以及其他Gas组件——特殊的Tron网络资源Energy和Bandwidth。

易用性 — 无需复杂设置即可发送交易。

GasFree的缺点

1. GasFree 仅在受支持的钱包和服务中可用。

2. The service provider can disable GasFree support at any moment.
3. Hidden fees or transaction limits may be imposed. By the way, the accompanying documentation includes a disclaimer that the transaction fee may be significantly higher than if the user paid the gas themselves, especially during high network congestion on Tron.

When using GasFree, the commission can be noticeably higher than when using "gas": current tests show amounts of 10–20 USDT per operation.
This is without even considering the payment for activating the GasFree Wallet (another 10 USDT).

能量租赁如何运作？

能量租赁 — 特殊服务在特定时间段（一小时或更长时间）内提供的计算资源，以降低 TRC-20 交易手续费。

Such rental allows the user to completely exclude TRX from transaction fees when interacting with smart contracts,
including when transferring USDT TRC-20.

租赁能量允许进行更多交易，同时最大限度地降低成本。

能量租赁的优势

• Commission reduction by 2–3 times compared to regular transfers.
• Availability for any wallets and services.
• Flexibility — you can rent the required amount of energy for different durations.
• Full automation — when using Telegram bots or web interfaces, such as NETTS's Workspace.

能量租赁的缺点

这种方法的缺点可能包括：需要预先计算所需的能量 (Energy) 量，以及需要在账户余额中保留一些 TRX 用于租赁。

并且在自动化充值的情况下，需要进行初始设置。

一些用户也会囤积额外的TRX，以防止网络过载导致交易冻结。

尽管可以通过租用更多能量或激活钱包自动充值来消除此因素，但如果在系统过载的情况下与智能合约交互。

例如，NETTS 能量租赁服务允许其客户（每天向数十个地址发送 USDT TRC-20）选择合适的余额充值方式：

• Host – this is "perpetual" Energy or the second option – resource supply according to a schedule approved by the client;
• Smart – trigger-based Energy supply: as soon as the resource reserves reach the specified level, the balance is replenished to the initial level.

GasFree 与 能量租赁：哪种更赚钱？

让我们根据关键参数比较这两种方法。

Parameter	GasFree	Energy Rental
Is TRX needed?	No	Yes
Fixed commission?	No (may depend on the provider)	Yes
Works with any TRC-20 tokens?	No (limited support)	Yes
Support in all wallets?	No	Yes
Suitable for mass transactions?	No	Yes
Transaction cost for transferring USDT TRC-20 to one address	from 10 USDT	~3-6 TRX (depending on recipient's balance)

结论：

1. The GasFree function is useful for large players who do not want to hold TRX and special resources to service a large number of addresses. But they must be prepared to pay an increased commission in USDT for convenience.
2. GasFree is not the best choice for the mass audience of Tron users, but for special cases (corporate wallets, exchanges, B2B services) it can be a convenient option.
3. GasFree is also convenient for beginners who find obtaining special resources complicated. But the high transaction fees prevent those who regularly interact with TRC-20 from using this method.
4. Energy rental is suitable for everyone, including holders of significant USDT volumes and those who regularly transfer stablecoins, interact with smart contracts, and avoid inefficient expenses that can be easily eliminated by renting Energy.

综上所述，在2025年，能量租赁仍然是降低Tron网络手续费的主要方法。它比质押更具优势，也比GasFree便宜得多。

主要的是仔细选择能量租赁服务。NETTS 提供易用性，即使对于 Tron 新手也是如此。无需注册或创建帐户。只需通过网站表单或 Telegram 机器人登录即可。选择付款方式 – 以每笔交易 3–6 TRX 的费率进行预付一次性付款，或存入 15 TRX 的押金，足够进行 2–5 笔交易。您还可以使用新功能 – 通过 Workspace 网页界面自动充值。

只需尝试一下它的运作方式，即可从NETTS能源租赁服务中获得真正的80% 优惠 – https://netts.io工作区存款 – 仅需 1 TRX。
