OnlyTron rents TRON energy for one hour, so a USDT TRC20 transfer costs about 2.45 TRX instead of the roughly 6.5 TRX the network burns when you hold no energy. You pay in TRX, delegation arrives within seconds, and you never stake or register. It works through a Telegram bot and an API.

Why it exists: an address that holds USDT burns about 65,000 energy per transfer, and an address that has never held USDT burns about 130,000. Staking TRX for your own energy locks funds for the 14-day unstake period, so renting is cheaper for occasional senders.
