Monitor USDT ERC-20 wallet balance with Etherscan and Telegram notifications

Overview This n8n workflow is specifically designed to monitor the USDT ERC-20 balance within a specific wallet. It uses Etherscan's public blockchain database, which does not require API authentication, to periodically check and process transaction data. This workflow is ideal for users who need an automated solution to track ERC-20 wallet transactions. Features - Automatic Monitoring: Executes every 5 minutes to capture new transactions. - Customizable Filters: Customize tracking based on parameters like transaction duration and wallet addresses. - Data Aggregation: Compiles transaction data into a single, structured list. - Formatted Outputs: Presents processed data in an organized format. - Telegram Tracking: Tracks wallet balances via Telegram notifications using the bot. Requirements - n8n Setup: Requires a self-hosted or cloud-based n8n instance. - Basic Understanding: Basic knowledge of n8n workflows and nodes. Installation and Configuration 1.

You can also monitor another token by entering a different contract address. 3.
