This is pseudonymous, not anonymous.
I don't know if there's a decentralized exchange that support Tron network especially USDT TRC20, I think you can only use swap platforms that doesn't require KYC although it's closed source.
And which is the cheapest fee ?
If you're looking for cheapest fee, I think non custodial wallet that integrating with swap platform inside the wallet is the best choice. Although I disagree if you want to use it for long term holding since it's closed source wallet.
