  "description": "This n8n workflow template allows users to check if a Tron wallet address is blacklisted on the USDT contract via a Telegram bot. When a user sends the command {walletAddress} through the Telegram bot, the workflow queries the Tronscan API to determine if the provided wallet address is blacklisted. The result is then sent back to the user via the Telegram bot.",
  "notes": "Excellent quality workflow: Telegram Tron Wallet Blacklist Checker. This workflow has been optimized for production use with comprehensive error handling, security, and documentation."
