To deploy the ERC-20 token contract, you need to write a deployment script.

• In the scripts directory, create a new file called deploy.js:

Steps to Deploy:

Now that you’ve built a basic DApp, you can explore more complex and real-world use cases. DApps can be used in various domains, including:

• pragma solidity ^0.8.0;: Specifies the version of Solidity.
• contract SimpleStorage: Defines a new smart contract named SimpleStorage.
• uint256 public storedData: Declares a public variable to store an unsigned integer.
• function set(uint256 x) public: A function to set the value of storedData.
• function get() public view returns (uint256): A function to retrieve the value of storedData.

After writing the smart contract, the next step is to deploy it on a test network to see it in action.
