If you’re interested in mining the depths of blockchain, tracking transactions becomes essential. This guide will detail how to set up a simple blockchain tracker that allows you to monitor Ether and token transfers for specific wallets and amounts. Think of it as your personal treasure map in the world of cryptocurrency!

Requirements

• Node.js version 8 or higher: Node 8+
• Yarn (optional): Yarn

Setup

Ready to set sail? Follow these simple steps to get your blockchain tracker up and running:

1. Clone the repository using Git:

git clone git@github.com:dsemenovsky/blockchain-tracker-example.git

2. Change directory into the cloned project:

cd blockchain-tracker-example

3. Install the necessary dependencies with Yarn (or use npm if you prefer):

yarn install

4. Fill out the .env file from .env.example:

In this configuration file, you will provide the token contract address, wallets, and the amount of tokens you want to track. Here’s an example format:

NODE_ENV=development
INFURA_URL=https://rinkeby.infura.io/CUNjkZ8qg6WZHqeFNJ
INFURA_WS_URL=wss://rinkeby.infura.io/ws
ETH_BLOCK_TIME=30
TOKEN_CONTRACT_ADDRESS=0xb4e95c65c23cab8c4fcaf15e4936c392e6ab21bf
WALLET_FROM=YOUR_WALLET_FROM_ADDRESS
WALLET_TO=YOUR_WALLET_TO_ADDRESS
AMOUNT=YOUR_AMOUNT

Running the Tracker

Once you’ve set up everything, it’s time to launch your blockchain tracker:

yarn start

This command will kick off your service. Now, perform a transfer from one wallet to another on the Rinkeby testnet.

Understanding the Code: An Analogy

Imagine setting up a bakery in a bustling town. You need to know not only how many loaves of bread you sell but also where they are going. The cloned project acts as your bakery, `yarn install` fills your pantry with ingredients needed to bake, while the `.env` file is your recipe book where you specify what goodies (tokens) you’re tracking. Once everything is set, starting the service is akin to opening your bakery doors, allowing customers (transactions) to flow in and out. By following these steps, you can efficiently manage your recipes and track your delicious creations (Ether and tokens)!

Troubleshooting Tips

If you encounter issues during setup or while running your tracker, consider the following troubleshooting ideas:

• Ensure Node.js and Yarn are correctly installed. You can verify this by running node -v and yarn -v in the terminal.
• Check your .env parameters for any typos, especially the token contract address and wallet addresses.
• If the service doesn’t start, ensure that you are connected to the Rinkeby testnet and that your wallets are properly funded with test Ether.
