Corporate users can connect via API, assign multiple wallets, and monitor consumption in real tim


The Energy becomes active within seconds and is automatically delegated to your address for use in smart contract calls or TRC-20 transfers. You top up your balance with TRX or USDT, select the required amount and period, and the system delegates resources directly to your wallet. The consumption of bandwidth and energy depends on the complexity and computational requirements of the transaction or smart contract. In the TRON network, each account has a certain amount of bandwidth and energy. Swap crypto in CoolWallet with full self custody and hardware level security.

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.

(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.
