Gas Optimization Development Tutorials, Guides & Insights

With the deployment script in place, you can now deploy your contract to a local blockchain or a testnet.

• Start a local Ethereum node using Hardhat:

Fallback and receive functions handle direct payments to contracts.

• Fallback: Called when no other function matches or if no data is provided.

• Choose data structures that minimize gas consumption. For example, mappings are generally more gas-efficient than arrays for storing large datasets.
• Example: Use a mapping instead of an array for storing user balances.

5. Avoid Unnecessary Computations

• 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.
