Gas Optimization Development Tutorials, Guides & Insights

Before you begin, make sure you have the following:

• Node.js and npm: Node.js is required to run the development environment, and npm is used to manage packages.
• Truffle or Hardhat: These are development frameworks for Ethereum. You can use either one, but for this tutorial, we will use Hardhat.
• MetaMask: A browser extension wallet to interact with your smart contract.
• OpenZeppelin Contracts: A library of secure smart contract components.

• Audit and review contracts before deploying to the mainnet.

• Remix IDE: Web-based IDE for writing and testing smart contracts.

Different operations in a smart contract consume different amounts of gas. Simple operations like adding two numbers are inexpensive, while more complex operations like loops or external contract calls can be costly. It’s important to understand how various Solidity operations consume gas.

Examples of Gas Costs:

• Switch to the "Deploy & Run Transactions" tab.
• Select "Injected Web3" as the environment to connect to MetaMask.
• Choose a test network like Ropsten or Kovan in MetaMask.
• Click "Deploy" and confirm the transaction in MetaMask.

• Once deployed, the contract will appear in the "Deployed Contracts" section.
• You can now call the set and get functions to interact with your contract.
