TRON Energy and Bandwidth: What You Need to Know

TRON uses an energy and bandwidth model for transaction fees rather than a simple gas fee system. Understanding this model helps you minimize the cost of sending TRX and TRC-20 tokens from Trust Wallet.

On the TRON network, transactions consume two resources: bandwidth and energy. Bandwidth is used for all transactions including simple TRX transfers. Energy is required specifically for smart contract interactions, including TRC-20 token transfers like USDT. Every wallet receives a daily allocation of free bandwidth, which is enough for a few TRX transfers per day at no cost.

For USDT TRC20 transfers, a transaction typically requires around 64,895 energy units. If your wallet does not have enough energy, the fee is burned in TRX. This can result in a fee of around 30 TRX per transfer if you have no staked energy. To avoid this, you can stake TRX to earn energy, or rent energy from energy providers.

Trust Wallet has integrated Tronify, a TRON energy rental service, which automatically finds the cheapest energy option for each transaction. This can reduce fees by up to 40% compared to paying with raw TRX. The optimization is applied automatically — no manual configuration is required. Users can see the estimated fee and any savings on the confirmation screen before approving a transfer.
