This n8n workflow enables users to verify if a Tron wallet address is blacklisted on the USDT contract using a Telegram bot. When a user sends a wallet address through Telegram, the workflow validates the address format, queries the Tronscan API to check blacklist status, and responds with the result. This automation simplifies monitoring wallet blacklists directly from Telegram, useful for traders, blockchain analysts, or crypto community managers who need quick blacklist checks.
