Is there a way to check who (which address) sent you USDT using the TRON(TRC20) network?

Hi all,

I want to ask a question regarding the USDT transactions using the TRON network.

Is there a way for me to understand from which address I received money?

I recently got 100$ USDT sent from a friend on my Trust wallet and upon going to the tronscan.org to understand who sent me the money I see the following:

It seems like all transactions are coming from this following address:

TJ7hhYhVhaxNx6BPyq7yFpqZrQULL3JSdb

This one contains 18$ million USDT.

My friend is not a millionaire lol, this is not his wallet address.

Can someone please explain this to me?

How does this work? Where can I check the actual wallet address that the money was sent from?

Thank you.
