🚀 Bitquery Sniper Trading Bot

The Sniper Trading Bot is an automated crypto trading tool built for detecting and trading newly created Four Meme tokens in real time.
It follows a simple, high-frequency strategy — buy instantly when the token launches and sell automatically after one minute.

🔍 How It Works: Detecting New Four Meme Tokens

The bot leverages Bitquery’s Protobuf Kafka Streams to receive token creation events in real-time from the BSC blockchain.

You can check out the Kafka Protobuf JS example for a step-by-step JavaScript implementation.

Key features:

• Monitors new token launches instantly via Kafka Streams
• Reduces latency using Finland-based (eu-north-1) deployment
• Fully integrates with Bitquery APIs for event data streaming

💰 Buying and Selling Tokens Automatically

The bot interacts with the Four Meme DEX Smart Contract through ethers.js.
We define custom wrapper functions:

• buyViaLaunchpad → Buys tokens as soon as they’re created
• sellTokenViaLaunchpad → Sells after a predefined delay (default: 1 minute)

☁️ Deployment Guide (Google Cloud)

You can deploy the bot to a cloud provider (recommended: Google Cloud) for 24/7 uptime.

Steps:

1. Create a VM (Virtual Machine) in region eu-north-1 (Finland) for minimal latency to the Bitquery Kafka service.

2. SSH into the VM and install dependencies:

   sudo apt-get update
   sudo apt-get install -y git curl
   curl -fsSL https://deb.nodesource.com/setup_20.x?utm_source=github_readme&utm_medium=referral&utm_campaign=evm_sniper&utm_content=node_setup&utm_term=node20 | sudo -E bash -
   sudo apt-get install -y nodejs

3. Verify installations:

   node -v
   npm -v
   git --version

4. Follow the setup section above.

5. Install pm2 process manager to run the bot continuously:

   sudo npm install -g pm2
   pm2 start index.js --name "evm-sniper"
   pm2 status
   pm2 logs evm-sniper
