TRX deducted but swap not completed

[anudwai]

I exchanged TRX for USDT, and the record shows that it was successful, but my USDT did not change, but my TRX was deducted instead.

Your transaction was an authorization transaction, not an exchange transaction. All transactions require energy, and since your free energy was insufficient, TRX was burned to cover the energy cost. You authorized the contract TCFNp179Lg46D16zKoumd4Poa2WFFdtqYj to trade your USDT. Usually, after you grant authorization once, this contract will not require authorization again in the future.
