Title: Scam with USDT TRC20 token
Post by: safar1980 on June 02, 2023, 09:08:06 PM
After the first payment with USDT TRC20 tokens, you can see a second transaction to a similar address from your wallet. The second transaction is 0 USDT. It really surprised me.
Then I found out that any programmer who knows how to make such smart contracts can send such a transaction,but he will pay a commission and it is possible to send only 0 tokens.
I found out about it today. If you copy wallets from the transaction history, then you can send tokens to a fraudulent address.

Do you mean that when you send or receive USDT from one wallet, immediately there will be another transaction added with a separate token that is not the exact same USDT sent or received?But this time it's only 0 tokens sent. Or is it the same USDT that will come to the wallet, but this time it's just 0 that will be sent, just like one can easily send out 0 matic under the polygon network and the only thing you have to pay is the fee?

I'm asking because I haven't used the Tron network for a long time now, and it will really be nice for one to take note of the recent happenings before they could be turned into scammers new method of sending fake coins.

You are right op that's known as address Poisoning in which the first and last letters of your address are same as of scammer. Main purpose of it to get benefit of those persons who copy address from explorer and use it for transactional activities and by accident they lost money.

The best practice is not to copy your address from last transaction on explorer because this scam will get you and you could lost lot of money. So keep safe and also spread such type of scams among your friends too so they could learn about it too.

The scammer does not need to use fake tokens, as the USDT smart contract has a bug that allows you to send zero transactions from your wallet.
This is an attack on your mindfulness. If you copy the address from a previous transaction, then you will pay the scammer for your inattention.
Do not copy addresses from transaction history.
