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.

For users seeking to balance efficiency, cost, and security on the TRON blockchain, this is a simpler, more practical, and reliable transaction option. For users who prioritize security, private keys remain securely stored in the secure chip of the CoolWallet hardware wallet throughout the Energy Rental process. 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. If the account does not have enough Energy, the TRON network automatically burns TRX to make up the difference, resulting in higher transaction fee

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.

(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, USDT transaction fee savings the system may still consume a small amount of TRX during the transaction to cover insufficient Bandwidth cost
