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.
How TRON Energy Rental Wor


For users who regularly transact on the TRON blockchain, this results in a clear overall cost advantage. Compared with paying transaction costs directly in TRX, Energy Rental significantly lowers actual transaction fees, making frequent token transfers far more cost-effective. This allows users to retain more of their native tokens while maintaining full transaction functionality on the TRON network. By integrating Tronify Energy Rental, CoolWallet helps users reduce the amount of TRX burned due to insufficient Energy when sending tokens.
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.

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. 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.

If the other party does not have a USDT balance, 131k (if insufficient energy needs to be burned, 13 TRX) energy is required. Currently, when a transfer is made and the other party has a USDT balance, it requires 65k (6.5 TRX is burned if the energy is insufficient) energy.

TRON Energy rental lets you minimize TRC-20 transaction fees and keep more of your crypto for real us

As a result, when sending TRX or TRC-20 tokens, users often end up paying higher transaction fees without realizing it. You can think of TRON as the platform and TRX as the digital currency used to power transactions and operations on that platfor


Gas-Free also simplifies onboarding for first-time stablecoin users. That means fewer stuck transfers and smoother onboarding for new wallets. Gas-Free flows remove this friction by applying a simple flat USDT fee, even when the recipient hasn’t interacted with the network before. Wallets like TronLink, Klever, and Guarda automatically deduct network fees in USDT and guide users through a quick one-time activation if required. Guarda Wallet introduced its "Gas Free TRON / TRX-Free Transactions" feature to remove the need for TRX when sending USDT (TRC-20). Users fund their GasFree wallet with USDT, and the first outgoing transaction automatically deducts a 1 USDT one-time activation plus roughly 1 USDT for the network fe
