Monitor USDT ERC-20 Wallet Balance with Etherscan & Telegram Alerts

This n8n workflow provides automated monitoring of USDT (Tether) ERC-20 token balances in a specified Ethereum wallet using the Etherscan API. It runs on a 5-minute schedule, fetching recent transaction data, applying customizable filters for duration and addresses, aggregating it into structured lists, and formatting outputs for clarity. Telegram integration sends instant notifications on balance changes, making it perfect for hands-free tracking without constant manual checks.

Key features include no-auth fallback for Etherscan public data (with optional API key for reliability), support for other ERC-20 tokens by swapping contract addresses, and robust data processing to compile transactions efficiently. Benefits encompass time savings for crypto users, reduced risk of missing critical transfers, and scalability for multiple wallets. It's ideal for traders, DeFi participants, or anyone managing ERC-20 assets needing proactive alerts.

Setup is straightforward: import the JSON into n8n, configure the User Data node with your wallet address, Etherscan API key, and USDT contract (0xdAC17F958D2ee523a2206206994597C13D831ec7), then link a Telegram bot for notifications. Use cases range from personal portfolio oversight to business treasury monitoring, enhancing security and decision-making in volatile crypto markets.
