EcoGas Station lets you send TRC-20 USDT from the wallet you already use, without burning the usual TRON gas. Sign up, top up a small TRX/USDT balance, add your T-address, and turn Auto on. Energy is delegated when you send; you never paste a seed phrase or private key. Non-custodial. With-U dest 6.6→3 TRX/send (−55%); no-U/exchange 13.2→6 TRX/send.
