# Cross-chain Operation of USDT(TRC20)

If you have USDT on Tron, you can also transfer it to `Super ZERO` as TUSDT via the cross-chain feature of EMIT Wallet, so you can enjoy the low Gas fees and privacy features of Super ZERO (SERO). You can also reverse the TUSDT on Super ZERO and transfer it back to Tron to become USDT.
