"What are the key considerations for optimizing gas costs in complex Ethereum smart contracts while ensuring security and scalability?"

Question

Techniques and best practices for reducing gas consumption in Ethereum smart contracts. Code optimization strategies that apply to various contract types (e.g., ERC-20, ERC-721) and scenarios.

Answer 1

here are some tips for reducing gas consumption in Smart Contracts:

• Use an appropriate data type for each variable. For example, use uint8 instead of uint256 if you only need to store a small number.
• Avoid unnecessary computations. For example, if you need to check if a value is greater than zero, use the > operator instead of >=.
• Use the payable keyword only when necessary. If you don't need to receive Ether, don't use it.
• Use the gas keyword to limit the amount of gas that a function can use.
• Use an external library for common tasks. This can save you from having to write your own code and can also help improve the security of your contract.
