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. 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. As a result, when sending TRX or TRC-20 tokens, users often end up paying higher transaction fees without realizing it. Energy rental services operate by delegating frozen TRX resources to users temporarily. Energy received from our service cannot be used for transfers made from cryptocurrency exchange


With Tronify, users can perform TRC-20 token transfers and various contract interactions without burning additional TRX due to insufficient Energy. By offering this idle Energy to users with immediate needs at a lower cost, overall resource efficiency is improved. Any Energy that is not used within its validity period expires naturally and cannot be accumulated or retained. Energy Rental is designed to address the issue of insufficient Energy at the time of sending a transaction. As a result, the more TRX that is staked, the more Energy the account receives. If an account does not have enough available Energy, the system burns TRX to cover the corresponding Energy cost in order to complete the transactio

How to Use Energy Rental on CoolWallet
All of this is automatically done by the NRG smart contract. Operating since 2022, our TRON Energy rent service has processed millions of TRC‑20 transfers. All data is encrypted in transit and at rest, and access is strictly controlled under GDPR and internal security policie


Add your public wallet address in the Tronex Energy dashboard Enable gas-free, high-volume transactions, withdrawals, and wallet operations with our automated Energy delegation system. Frequent users save between 30 % and 60 % of fees depending on transaction flow, market rates, and token type. When your wallet has no Energy, TRC20 transaction fees are covered by burning TRX — 6.5 to 13 TRX per transfer. With rented resources you cover the same load at a lower, predictable cost. Renting Energy & Bandwidth replaces TRX burn on TRC‑20 and keeps wallets liquid.
Choose TRX Energy amount & term
When a transaction involves smart contract interactions, such as TRC-20 token transfers, approvals, or other contract calls, it consumes Energy. 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. This is the main reason many users unknowingly pay higher fees when sending TRC-20 token transactions. When sufficient resources are available, transactions consume only Bandwidth and Energy and require little to no TRX. With this integration, CoolWallet users no longer need to manually manage complex resource configurations when sending TRC-20 transactions. However, many users are not familiar with TRON’s resource mechanism, such as Energy and Bandwidth.
Energy Price History
(The TRON network can use resources or consume TRX to achieve the purpose of data on-chain.) Bandwidth and energy are the resource systems used for processing and executing smart contracts and transactions. We let you get the energy you need to complete transactions without staking TRX or waiting through long unfreezing periods. Learn how ETH staking works, compare staking methods, and earn rewards with flexible staking, auto-compounding, and full self-custody protection. If your wallet’s TRX balance is above 0.8 TRX, even when Energy is paid with USDT, instant wallet resource access the system may still consume a small amount of TRX during the transaction to cover insufficient Bandwidth cost


It cannot be retained, reused for future transactions, or accumulated in the account. If there is enough Energy to complete the transaction, the CoolWallet App will not display any transaction fees. 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. Energy Rental only provides the resources required to execute transactions. For users sending USDT, this means they can transfer USDT even without holding TRX, offering greater payment flexibility and easier cost control. In addition, users can choose to pay Energy Rental fees using TRON-based USDT or the native token TRX.
