🧠 Introduction to EVM Wallet Tracking Bot

This guide will walk you through creating a sophisticated wallet tracking bot that monitors transactions across multiple EVM chains (Ethereum, Polygon, Arbitrum, Base, BSC, etc.) and sends detailed notifications via Telegram. By the end, you'll have a powerful tool that provides instant alerts about token purchases, sales, swaps, transfers, and other on-chain activities.

Unlike basic monitoring tools that only show balance changes, this professional-grade solution breaks down transactions with full context, delivering human-readable alerts directly to your Telegram. With support for multi-wallet and multi-chain tracking, historical data storage via MongoDB, and an intuitive command interface, this bot serves as your personal blockchain analyst, giving you the tactical edge needed to make informed decisions in real-time.

Why Wallet Monitoring Matters in DeFi

In the high-stakes, real-time world of DeFi, staying ahead of market movements and tracking key wallets is no longer a luxury—it's a necessity. With thousands of wallets making transactions every second across multiple chains like Ethereum, BSC, and Polygon, traders and developers need instant visibility into wallet activities.

Imagine this: You're a crypto trader watching a major whale wallet. Suddenly, the wallet dumps a massive amount of tokens. If you see this minutes later, it's already too late. But what if you got notified the second it happened? That’s where the EVM Wallet Tracking Telegram Bot comes into play.

This tool lets you track wallet activities across EVM-compatible blockchains in real time. Whether you’re a DeFi enthusiast, investor, security analyst, or just a curious blockchain explorer, this bot gives you a tactical edge with up-to-the-second notifications.

What Makes This Bot Different?

Most bots just show wallet balance changes, but this one breaks it down with full context:

  • Detects sells, buys, swaps, and contract interactions
  • Sends formatted, human-readable alerts to Telegram
  • Supports multi-wallet and multi-chain tracking
  • Offers historical data storage via MongoDB
  • Easy command-line interface through Telegram bot commands

It's not just a tracker—it's your personal blockchain analyst, sliding into your Telegram DMs.

🤖 Setting Up the Telegram Bot

Creating Your Telegram Bot with BotFather

First things first: you need your own Telegram bot. Setting it up is easy:

  1. Open Telegram and search for @BotFather.
  2. Send /newbot.
  3. Give it a name like EVM Wallet Tracker.
  4. Choose a unique username ending in bot, such as evmwallettrackbot.
  5. BotFather will return a Bot Token — save this securely!

Understanding Chat IDs & Bot Tokens

To send messages to yourself or a group, your bot needs to know where to send them. That’s where Chat IDs come in.

There are a few ways to get this:

  • Send a message to your bot and use a script to log the response
  • Use Telegram’s API directly
  • Use bot management tools

Once you have your Bot Token and Chat ID, your bot can send messages directly to your Telegram—nice!

Integrating Telegram Bot with Your Code

The bot uses the Telegram Bot API, which makes sending messages as simple as an HTTP request. But this bot comes fully packaged—commands are already built-in for you:

`/start` - See welcome message  
`/track [chain] [address]` - Start tracking  
`/list` - List tracked wallets  
`/remove` - Remove a wallet  
`/stop [chain] [address]` - Stop tracking temporarily, 
`/resume [chain] [address]` - Resume tracking again, 
`/stopall` - Stop all tracking temporarily, 
`/resumeall` - Control tracking
