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.

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.

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.
