Gas Optimization Development Tutorials, Guides & Insights

• Hardhat will compile your contract and generate the necessary artifacts in the artifacts directory.

To deploy the ERC-20 token contract, you need to write a deployment script.

Use require, assert, and revert for error handling.

• require: Checks conditions and reverts if false. Used for input validation.

• Avoid Storage in Loops: Writing to storage inside loops can quickly escalate gas costs. If you must use a loop, limit its execution or use memory instead of storage.
• Use Events for Logging: Instead of storing logs on-chain, use Solidity events. Events are cheaper and can be accessed off-chain by listening to logs.
• Optimize for Minimal Execution Paths: Design your smart contract functions to have the most common execution path consume the least gas.
• Leverage immutable and constant Keywords: For variables that won’t change after deployment, use immutable or constant to save on gas.
• Consider Upgradable Contracts: For complex contracts that may require changes over time, consider using upgradable contracts to avoid redeployment costs.

To understand the impact of gas optimization, let’s look at some real-world examples from popular Ethereum projects:

A smart contract is a self-executing contract with the terms of the agreement directly written into code. It runs on the Ethereum blockchain and automatically enforces the terms of the contract. Once deployed, it operates independently without the need for a central authority or intermediary, making transactions transparent, secure, and immutable.
