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.

• 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.

Why Gas Matters:

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:

Key Features:

• Decentralized: Operates on the blockchain, not controlled by any single entity.
• Trustless: Executes automatically when conditions are met, without requiring trust between parties.
• Immutable: Once deployed, the contract's code cannot be changed, ensuring the terms are fixed.
