During the operation of the TRON chain, each confirmation gas fee includes bandwidth and energy consumption. TRX assets only consume bandwidth during transfers, while other assets require both bandwidth and energy. Bandwidth serves as a relatively low basic fee and can be ignored, whereas energy consumption is costly. Energy is a resource on the TRON chain allocated daily to users who stake TRX. You can keep the energy for your own use or lease it to others. When users conduct transactions or transfers on the TRON chain, if they lack energy, they will directly consume TRX (each transaction requires approximately 30 to 100 TRX). If they have energy, they will consume energy instead of TRX. Using energy instead of TRX can save 70% of the cost.
