TRX transaction fees are one of the most distinctive features of the TRON blockchain. Unlike Ethereum's gas-based model, TRON uses two separate resources — Energy and Bandwidth — to power every transaction on the network. Understanding how these resources interact is the key to keeping your transfer costs as low as possible.
Bandwidth is consumed by all transaction types, including simple TRX transfers. Each TRON account is automatically allocated 600 free Bandwidth points every day. A standard TRX transfer consumes approximately 268 Bandwidth points, which means most everyday transfers are completely free as long as your free daily quota is sufficient. When your free Bandwidth runs out, the network burns a small amount of TRX instead — typically around 0.3 TRX per extra transfer.
Energy is a different resource that is only needed for smart-contract transactions, most notably TRC-20 token transfers such as USDT. Energy is not given out for free on a daily basis; you must either stake TRX to generate Energy or burn TRX directly to cover the cost. As of August 2025, following TRON governance Proposal #104, the energy unit price was reduced from 210 SUN to 100 SUN, effectively halving the cost of all USDT transfers on the network.
When a recipient wallet has never held USDT before, the transfer costs approximately 13.4 TRX in burned fees (down from 27.25 TRX before Proposal #104). If the recipient already holds any amount of USDT, the fee drops to around 6.4 TRX because the smart-contract initialization step is skipped. This distinction can save you a meaningful amount on recurring transfers.
