The classic TRON trap: USDT sits on your wallet, but you cannot send it — the fee needs TRX or energy, and you have neither. Keep in mind that in this situation USDT cannot be sent anywhere — not to the recipient, not to an exchange, not to a swap service. So the first step is always the same: get a little TRX onto your wallet.
Withdraw TRX from an exchange. If you have an exchange account, withdraw TRX directly to your wallet — a few coins are enough. The withdrawal needs no fee from your wallet.
Ask someone to send a couple of TRX. A counterparty, a friend, a colleague — a TRX transfer costs almost nothing and needs no energy. For a one-off situation this is the fastest option.
Buy TRX via P2P. No exchange account — buy a small amount of TRX from a P2P seller, credited straight to your wallet.
Once you have a few TRX, open Tronergy in the Discover tab of TronLink:
Important: never send USDT to a swap service from an exchange account (Binance, Bybit, OKX) — the TRX would go to the wallet of the exchange, not yours. Personal wallets only: TronLink, Trust Wallet, Ledger.
Keep at least a few TRX on your wallet. That is enough to always get energy and send USDT without extra steps.
