How do I check my ERC20 token balance?

To retrieve the balance of an ERC-20 token, you need to follow a series of steps. Begin by creating a project directory. This will serve as the container for all your project files.

To create a new directory for your project, open your terminal or command prompt. Use the mkdir command followed by the name of your directory. For this example, type mkdir retrieveBalance. This will create a new folder named retrieveBalance in your current working directory.

Next, navigate into the newly created directory. Use the cd command followed by the name of your directory. In this case, type cd retrieveBalance. This will change your current working directory to the retrieveBalance folder.

Once you are in the project directory, you need to install the required packages. For retrieving the balance of an ERC-20 token, you will need the web3 package. This is a JavaScript library that allows you to interact with Ethereum blockchains.

To install the web3 package, use the npm install command followed by the package name. Type npm install web3. This will download and install the web3 package and its dependencies into your project directory.
