How to Use Energy Rental on CoolWallet
Any remaining Energy after the transaction is completed, or any Energy that is not used within the validity period, will automatically expire. The Energy Rental fee varies depending on the transaction’s resource requirements. Currently, Energy Rental supports standard TRC-20 token transfer transactions only and does not apply to other transaction types. If Energy is insufficient and Energy Rental is not enabled, TRX will be burned as the transaction fee. If there is enough Energy to complete the transaction, the CoolWallet App will not display any transaction fee

All transactions must be signed by the user, ensuring full control over assets. In addition, users can choose to pay Energy Rental fees using TRON-based USDT or the native token TRX.

As a result, when sending TRX or TRC-20 tokens, users often end up paying higher transaction fees without realizing it. However, many users are not familiar with TRON’s resource mechanism, such as Energy and Bandwidt
