To swap TRX to USDT, choose TRX on Tron as “from” and USDT (TRC-20) as “to”, review the quote and sign: the swap settles in one transaction through Tron DEX routes such as SunSwap. On October 23, 2026 a swap of about $990 of TRX returned about $987 of USDT, but the energy cost (about $25 without staked TRX) was the biggest fee.
Key Takeaways
- Route: same-chain on Tron, or cross-chain to USDT on another network.
- Time: one transaction on Tron; about a minute to Solana.
- Biggest cost: energy for the contract call, not the swap fee.
- Check the contract: real USDT on Tron is

Why Energy Matters on Tron
Every Tron transaction uses bandwidth, and smart contract calls such as a DEX swap also use energy. If your account has no energy, Tron burns TRX to pay for it. In the quotes above that was about $24-25 per swap, more than ten times the route fee. If you swap or send TRC-20 tokens often, stake TRX for energy first; the staked TRX stays yours and energy refills daily.
Fake USDT Tokens on Tron
Tron token lists contain lookalike tokens with names such as “US DT” and “U S D T” (both appear in the LI.FI token list on October 23, 2026). They have no value. Real USDT on Tron is TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t. Select USDT from the widget list rather than pasting an address from a message, and check the contract on Tronscan if in doubt.
Step by Step
- Connect a Tron wallet that holds TRX.
- From: TRX on Tron. To: USDT on Tron, or USDT on another network.
- Check the quote: amount, energy cost and price impact.
- Confirm and keep a few TRX for the next transaction.
A multichain wallet such as Gem Wallet holds TRX and USDT on several networks in one app and lets you stake TRX for energy.
Mistakes to Avoid
- Swapping all TRX: leave some TRX for bandwidth and energy, or you cannot move the USDT afterwards.
- Fake tokens: ignore USDT lookalikes with odd spacing.
- Wrong network: an exchange may expect USDT on Ethereum or BNB Chain; see USDT networks.
