Introduction
TRON has become a preferred blockchain network for stablecoin transfers and on-chain interactions with its high-speed, low-cost transactions. However, many users are not familiar with TRON’s resource mechanism, such as Energy and Bandwidth. As a result, when sending TRX or TRC-20 tokens, users often end up paying higher transaction fees without realizing it.
To make the TRON network more intuitive and seamless to use, CoolWallet continues to optimize its TRON-related features and has officially integrated the Tronify Energy Rental service. With this integration, CoolWallet users no longer need to manually manage complex resource configurations when sending TRC-20 transactions. Transactions can be completed smoothly while effectively reducing transaction costs.
While maintaining full self-custody and asset security, CoolWallet users can simply focus on the transaction itself and enjoy a simpler, more stable TRON experience.
What Is TRON Energy Rental
TRON’s Resource Mechanism
On traditional blockchain networks, transactions typically require paying fees in the native token. For example, when sending ERC-20 tokens on Ethereum, users must pay on-chain transaction fees in ETH. In contrast, TRON adopts a resource-based design. Transactions primarily consume the available Bandwidth and Energy in an account, meaning transaction fees on the TRON network do not always need to be paid directly in the native token, TRX.
When sufficient resources are available, transactions consume only Bandwidth and Energy and require little to no TRX. However, when Bandwidth or Energy is insufficient, the system automatically burns TRX to make up for the required resources, which increases the actual transaction fee. This is the main reason many users unknowingly pay higher fees when sending TRC-20 token transactions.
Energy Rental is designed to address the cost issues caused by insufficient resources. Through the Energy Rental mechanism, users do not need to stake or hold TRX long term and can still complete transactions on the TRON network at a lower and more predictable cost.
What Are Bandwidth and Energy
Bandwidth is a resource on the TRON network used to process basic transactions, primarily native token TRX transfers. The more data a transaction contains, the more Bandwidth it consumes. On TRON, each account receives a fixed amount of free Bandwidth every day, which can be used to cover basic transaction needs. If additional Bandwidth is required, it can be obtained by staking TRX.
Energy measures the computational resources required for the TRON Virtual Machine (TVM) to execute operations. When a transaction involves smart contract interactions, such as TRC-20 token transfers, approvals, or other contract calls, it consumes Energy. If an account does not have enough available Energy, the system burns TRX to cover the corresponding Energy cost in order to complete the transaction.
Energy is primarily generated through staking TRX. The total amount of Energy produced by the TRON blockchain each day is fixed and distributed proportionally based on the amount of TRX staked by each account. As a result, the more TRX that is staked, the more Energy the account receives.
Why You Need Energy When Sending Transactions
On the TRON blockchain, Energy is a critical resource for successfully sending TRC-20 tokens. When a transaction is initiated, the system calculates the required Energy in real time. If the account does not have enough Energy, the TRON network automatically burns TRX to make up the difference, resulting in higher transaction fees.
Energy Rental is designed to address the issue of insufficient Energy at the time of sending a transaction. By obtaining the required Energy just before the transaction is executed, users can complete transactions at a stable and predictable cost without staking TRX in advance, making the entire process smoother and more efficient.
Why Energy Rental Is More Cost-Effective
With Energy Rental, transaction costs are typically lower than directly burning TRX. This is because some Energy service providers obtain large amounts of Energy by staking TRX for a limited period. Any Energy that is not used within its validity period expires naturally and cannot be accumulated or retained.
By offering this idle Energy to users with immediate needs at a lower cost, overall resource efficiency is improved. Users can complete transactions in a more cost-effective way, while service providers make better use of otherwise unused resources. This creates a more efficient and practical solution for both providers and users.
What Is Tronify
Tronify is a service provider focused on TRON network resource management. It offers real-time Energy Rental solutions that help users obtain the required Energy before executing transactions, enabling smart contract operations to be completed smoothly.
With Tronify, users can perform TRC-20 token transfers and various contract interactions without burning additional TRX due to insufficient Energy. This effectively reduces transaction costs and improves the overall user experience.
Tronify provides Energy resources only and does not participate in asset custody, transfers, or transaction signing. All asset control and transaction authorization are handled entirely by the user, fully preserving TRON’s decentralized and self-managed model.
Benefits of Using Energy Rental on CoolWallet
By integrating Tronify Energy Rental, CoolWallet helps users reduce the amount of TRX burned due to insufficient Energy when sending tokens. This allows users to retain more of their native tokens while maintaining full transaction functionality on the TRON network.
Compared with paying transaction costs directly in TRX, Energy Rental significantly lowers actual transaction fees, making frequent token transfers far more cost-effective. For users who regularly transact on the TRON blockchain, this results in a clear overall cost advantage.
In addition, users can choose to pay Energy Rental fees using TRON-based USDT or the native token TRX. For users sending USDT, this means they can transfer USDT even without holding TRX, offering greater payment flexibility and easier cost control.
For users who prioritize security, private keys remain securely stored in the secure chip of the CoolWallet hardware wallet throughout the Energy Rental process. All transactions must be signed by the user, ensuring full control over assets. The entire process involves no asset custody or private key sharing, preserving full self-custody and on-chain transparency while reducing transaction costs.

How to Use Energy Rental on CoolWallet
Step-by-Step Guide
Step 1. Initiate a TRC-20 token transfer. In this example, we are going to send TRON-based USDT.
Step 2. You can choose to pay the Energy Rental fee using TRON-based USDT or the native token TRX. If TRX is selected, make sure the Energy Rental toggle is enabled.
Step 3. In this example, USDT is selected to pay the Energy Rental fee.
Before completing the TRC-20 token transfer, you must first sign the Energy Rental transaction.
Step 4. After the Energy Rental transaction is completed, you can proceed to sign and complete the TRC-20 token transfer.
Please note: If you choose to pay the Energy Rental fee using TRON-based USDT
-
If your wallet’s TRX balance is below 0.8 TRX, the system will automatically rent sufficient Energy and Bandwidth to cover the transaction. In this case, all required Energy and Bandwidth are paid in USDT, and no additional TRX is consumed.
-
If your wallet’s TRX balance is above 0.8 TRX, even when Energy is paid with USDT, the system may still consume a small amount of TRX during the transaction to cover insufficient Bandwidth costs.

FAQs
Q1. Does using Energy Rental affect the security of my assets?
No. Energy Rental only provides the resources required to execute transactions. Private keys remain securely stored in your CoolWallet hardware wallet, and all transactions must be signed by you, ensuring full self-custody and on-chain transparency.
Q2. Is Energy Rental mandatory?
No. You can choose whether to enable Energy Rental when sending TRC-20 token transactions.
If there is enough Energy to complete the transaction, the CoolWallet App will not display any transaction fees. If Energy is insufficient and Energy Rental is not enabled, TRX will be burned as the transaction fee.
Q3. Why are there two transactions when using Energy Rental?
This is because Energy Rental and the TRX-20 token sending transaction are two separate steps. The system first completes the Energy Rental transaction to ensure sufficient Energy, and then executes the TRC-20 token transfer. This is normal behavior.
Q4. What happens if the Energy Rental transaction fails?
If the Energy Rental transaction fails, you can try again. If it still cannot be completed successfully, you can still choose to complete the transaction by paying the transaction fee directly in TRX.
Q5. Which transactions does Energy Rental support?
Currently, Energy Rental supports standard TRC-20 token transfer transactions only and does not apply to other transaction types.
Q6. Is the Energy Rental fee fixed?
No. The Energy Rental fee varies depending on the transaction’s resource requirements. The actual fee is shown on the transaction confirmation screen and is usually lower than directly burning TRX.
Q7. What happens if the rented Energy is not fully used?
Rented Energy is valid only for the current transaction and for 10 minutes. Any remaining Energy after the transaction is completed, or any Energy that is not used within the validity period, will automatically expire. It cannot be retained, reused for future transactions, or accumulated in the account.
Q8. If I pay the Energy Rental fee with USDT, will TRX still be consumed?
It depends on the amount of TRX held in your wallet.
If you choose to pay the Energy Rental fee using TRON-based USDT and your wallet’s TRX balance is below 0.8 TRX, the system will automatically rent sufficient Energy and Bandwidth to cover the transaction. In this case, all required Energy and Bandwidth are paid in USDT, and no additional TRX is consumed.
If your wallet’s TRX balance is above 0.8 TRX, even when Energy is paid with USDT, the system may still consume a small amount of TRX during the transaction to cover insufficient Bandwidth costs.
