You’ve now created and deployed your own ERC-20 token using OpenZeppelin. This token adheres to the ERC-20 standard, making it compatible with wallets, exchanges, and other Ethereum-based applications. OpenZeppelin simplifies the process, ensuring that your token is secure and follows best practices. From here, you can further customize your token, add additional features, or integrate it into decentralized applications.

• Hardhat: Flexible development environment for Ethereum.

• Ganache: Personal blockchain for Ethereum development.

Key Points:

• Gas Limit: The maximum amount of gas a user is willing to spend on a transaction.
• Gas Price: The amount of Ether a user is willing to pay per unit of gas.
• Gas Cost: The total amount of gas consumed by a transaction, multiplied by the gas price, determines the total fee paid.

After deployment, you can test your contract by interacting with its functions:

• Set a Value: Use the set function to store a number in the contract.
• Get the Value: Use the get function to retrieve the stored number.
