Smart Contracts Programming Tutorials, Guides & Best Practices

• Open the Hardhat console:

     npx hardhat console --network localhost

Several tools can help you analyze and optimize gas consumption in your smart contracts:

• Remix IDE: Provides real-time gas estimates while writing and testing smart contracts.
• Solidity Coverage: A tool for generating gas reports and identifying expensive operations in your code.
• ETH Gas Station: An online service that provides insights into gas prices and recommended gas limits for transactions.

To interact with the Ethereum network, you need to connect MetaMask to your DApp.

Steps to Connect MetaMask:

• 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.

You’ll notice that calling the set function will require gas (a small amount of Ether) to execute, whereas calling the get function is free as it’s a view function.
