Add your public wallet address in the Tronex Energy dashboard Enable gas-free, high-volume transactions, withdrawals, and wallet operations with our automated Energy delegation system. 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.
