Where the exchange name comes from
The name is a public tag on Tronscan, cached for a week. Known names include Binance, Bybit, OKX, HTX, KuCoin, Gate.io, MEXC, Bitget and other large exchanges. If Tronscan has no tag, that line is left off. Nothing is guessed.
This works on TRON transfer alerts. An address with no public name stays blank even if it moves a lot of money.
Exchange hot wallets are not monitored
If you paste a TRON address that Tronscan already tags as one of those exchanges, the bot does not save it. Those wallets transfer constantly. Watch your own wallet instead, and read the exchange name on the other side of each transfer.
Questions
Can I see if a USDT transfer came from Binance?
Yes, on TRON, when the sender is a publicly tagged Binance wallet. The alert shows From: Binance under the amount.
Why was my exchange address refused?
Hot wallets of known exchanges are not added. Send a personal wallet. If you think the tag is wrong, contact support from the message.
