Build a Telegram Buy Alert Bot for Your Token (Python + BSC + Web3)

🧠 Why You Need a Buy Alert Bot for Your Token

Launching a token is one thing. Creating community engagement and hype is another.

Every buy on your token matters — especially the big ones.
But if no one knows it happened, that momentum is wasted.

That’s where a Telegram Buy Alert Bot comes in.
It instantly notifies your community when someone buys your token — showing the amount, wallet address, USD value, and more.

"Hype isn't automatic — it's built one alert at a time."

💡 What the Bot Can Do

This Telegram bot:

• Detects buy transactions on PancakeSwap (BSC) / Uniswap (ETH)

• Tracks your specific token’s address

• Sends real-time alerts to your Telegram group or channel

• Shows:

  • 🧾 Buyer wallet (shortened)

  • 💰 Amount bought

  • 💵 USD equivalent

  • 📊 Buy source (wallet or DEX)

You can also customize:

• Minimum buy value for alert

• Emojis, alert tone, channel style

• Target token & chain (BSC, ETH, etc.)

🛠️ Built with Modern Stack

• Python

• Web3.py for blockchain interaction

• Telegram Bot API to send messages

This bot isn’t a random GitHub script.
It’s a production-grade tool I’ve refined for actual token teams — fully customizable and hosted.

🔍 How It Works (Simplified)

1. Connects to BSC using a RPC endpoint

2. Listens to your token's liquidity pool Swap Events

3. Filters out buy transactions only

4. Extracts key data like wallet, token amount, USD value

5. Formats a clean alert message

6. Sends it to your Telegram group

🧪 How the Code Works

Here’s a simplified breakdown of how I built the Telegram Buy Alert Bot:

1. Connecting with the blockchain

    from web3 import Web3
    web3 = Web3(Web3.HTTPProvider("YOUR_RPC_URL_HERE"))
   
    if web3.is_connected():
        print("Connected to the blockchain, Polling for events...")
   

2. Listen for token pair Swap Events (Buy or Sell)

    import json 
    PAIR_ABI= json.loads("") #You can get this from your pair contract via bscscan or ethscan
   
    pair_contract = web3.eth.contract(
        address=Web3.to_checksum_address(os.getenv("PAIR_ADDRESS")),
        abi=PAIR_ABI
    )
    swap_event = pair_contract.events.Swap()
    logs = swap_event.get_logs(fromBlock=from_block, toBlock=to_block) # U have to create a python logic to keep polling continous block to not miss any buy
   

3. Filter Buy Transactions

    TOKEN_NUMBER = 1 # Each pair have different token number u can check ethscan pair contract -> code -> read contract to check if "token1" is your token address if yes token number is 1 else it will be bnb 
    valid_tx = []
    for log in logs:
        # Determine which is token amount based on TOKEN_NUMBER
        if TOKEN_NUMBER == 0:
            token_in = amount0In / (10 ** TOKEN_DECIMALS)
            token_out = amount0Out / (10 ** TOKEN_DECIMALS)
            base_in = amount1In / (10 ** 18)
            base_out = amount1Out / (10 ** 18)
        else:
            token_in = amount1In / (10 ** TOKEN_DECIMALS)
            token_out = amount1Out / (10 ** TOKEN_DECIMALS)
            base_in = amount0In / (10 ** 18)
            base_out = amount0Out / (10 ** 18)
   
        is_buy = base_in > 0 and token_out > 0
        if is_buy:
            data = {
                "status": "processed",
                "bnb_in": float(round(base_in, 5)),
                "tokens_out": float(round(token_out, 4)),
                "txn_hash": log['transactionHash'].hex(),
                "to": log.get("to")
            }
            valid_tx.append(data)
   

4. Send alert to telegram

    from telebot import TeleBot
   
    BOT_TOKEN = ""
    CHAT_ID = "" # Make sure bot admin in the chat
    bot = TeleBot(BOT_TOKEN)
   
    msg = """
    📢 *New Buy Detected!*
   
    *💰 Buyer:* [{to_address[0:15]}..............](https://bscscan.com/address/{to_address})
    *🔄 Spent:* `{bnb_in}` BNB
    *🪙 Amount:* `{tokens_out}` 
    """.strip()
   
    for tx in valid_tx:
        msg_final = msg.format(to_address=tx['to'], bnb_in=tx['bnb_in'], tokens_out=tx['tokens_out'])
        bot.send_message(CHAT_ID, msg_final)
