What is TRON bandwidth?
re-energy can rent bandwidth alongside energy when your free daily quota runs out. Bandwidth covers the byte size of a TRON transaction—ordinary addresses get a small free daily allowance, but heavy activity still needs more bandwidth or TRX burn.
Free daily bandwidth
Active TRON addresses typically receive about 600 free bandwidth points per day. Simple transfers may fit; busy wallets and contract calls often need more.
Bandwidth + energy together
USDT TRC-20 transfers consume both resources. Energy usually dominates the fee; bandwidth still matters when the free pool is empty. re-energy can rent bandwidth as well as energy.
