10 Advanced Solidity Gas Optimization Techniques

The rapid development of the blockchain and Ethereum domain is undoubtedly good news in this technology-centric era. However, it is important to keep in mind that high gas fees are an urgent problem that cannot be ignored. In fact, significant gas fees are a major concern that can reduce the attractiveness of Ethereum. However, the problem can be solved wisely by adopting advanced Solidity gas optimization techniques. Let’s take a look at some of the best Solidity gas optimization techniques.

Insights into gas optimization come from Solidity.

Solidity is a programming language designed for developing smart contracts. While using Solidity, you should be familiar with the concepts of gas and gas optimization. Gas is basically a unit that measures the amount of computational effort required to perform a specific task on Ethereum.

Solidity gas optimization involves processes and practices that minimize costs while running Solidity smart code. Prioritizing gas-optimized Solidity is essential to understanding cost aspects and supporting sustainability.

Best solidity gas optimization technology

Now that you know the importance of gas optimization in Solidity, it’s time to focus on some key techniques. The main question that may be bothering you is how to optimize gas in Solidity. Below are some of the best Solidity gas optimization techniques that can help you answer this question.

• Replace array with mapping

Arrays and maps are two data types that help us describe lists of data in Solidity. It is very common to use array data structures while working with Solidity. But did you know that this increases the gas level significantly? You can minimize this problem by using maps instead of arrays. Doing so can save you over 2000 gas on every read. This mapping function is a much cheaper option compared to arrays. It is one of the most popular Solidity gas optimization techniques that you can use.

Reducing the data written to the chain can help minimize gas consumption. Less data means less storage is needed to store variables. As a result, there is an opportunity to minimize the gas required by smart contracts. A simple trick to follow is to use events to store off-chain data instead of using on-chain data storage options. This is definitely one of the best techniques to optimize Solidity gas.

• Using constants and immutable variables

A smart way to optimize gas in Solidity is to use constants and immutable variables. This step can obviously help reduce gas costs significantly. These variables are an ideal choice because they do not consume a lot of storage space within the Ethereum Virtual Machine.

With constants and immutable variables, value assignments are made only during the creation of a smart contract. Furthermore, they are read-only afterwards. Therefore, these variables are more cost-effective than regular variables.

• Using the Solidity Compiler Optimizer

One of the best Solidity gas optimization techniques is to enable or use the Solidity compiler optimizer. Its role is important because it helps to transform complex expressions into simpler versions. Thus, the code size is reduced. And that’s not all! It also reduces the execution cost, deployment cost, and cost associated with function calls. Gas optimization is a useful strategy that can facilitate Solidity.

• Optimization of unused variables

One of the most popular solidity gas optimization techniques is optimizing unused variables. Often, irrelevant or unnecessary variables are kept while executing smart contracts. This is a bad practice that increases the overall gas cost. Removing unused variables can optimize smart contracts and reduce gas costs. This technique is important because it helps free up unused space.

• Leveraging indexed events

Events are an important part of blockchain. The role of events is essential because they allow users to know when something happens within the blockchain network. In Solidity, events serve as the ultimate shortcuts to increase the speed of smart contracts and the operation of external systems. Deploying indexed events allows you to efficiently track all activities related to smart contracts. Using indexed events can reduce the overall gas consumed.

• Replace dynamically sized arrays with fixed-sized arrays

One of the best techniques to optimize Solidity gas is to use fixed-size arrays instead of dynamic-size arrays. If you need to use arrays in your smart contract, you can choose the fixed-size version. One of the main limitations of dynamic-size arrays is that they can grow indefinitely. This can significantly increase gas costs. However, fixed-size arrays do not have this problem. Because of their fixed nature, there is no risk associated with indefinite growth of arrays and gas costs.

• Avoid using variables less than 256 bits.

The variables you use in Solidity can have a direct impact on the gas consumed. You should not use variables lower than 256 bits. If you use uint8, you should know that it is a very inefficient option. Instead, you should choose uint256 in Solidity. This is a much more efficient approach that helps to minimize gas costs by ensuring gas optimization.

• Using external visibility modifiers

When it comes to Solidity, it is important to use the visibility that best suits your various functions. It can certainly be used as an effective measure to help optimize the gas required while creating smart contracts. It is important to keep in mind that choosing an external visibility modifier is one of the best options to consider. It is very gas efficient compared to the public option.

For public functions, the gas optimization is low. This is because public functions must support both external and internal calls. However, for external functions, they can only read from calldata, so there is no need to copy data to memory. This feature makes for a useful gas optimization technique.

• Use storage pointers instead of memory

When applicable, you should use storage pointers instead of memory. In Solidity, a storage pointer is a variable that refers to a specific location in the storage of a smart contract. You should know how to use storage pointers efficiently so that you can avoid reading unrelated storage. This is a gas-efficient approach that helps minimize gas costs in Solidity.

The higher the memory, the higher the gas cost in Solidity. While developing smart contracts on the Ethereum blockchain network, you should try to reduce the overall memory usage. By utilizing storage pointers, you can not only save memory, but also optimize gas in Solidity.

Identifying the various Solidity gas optimization techniques can certainly help answer the question of how to optimize gas in Solidity. The rising gas costs can be really burdensome, so you should consider the techniques provided to optimize gas usage and reduce gas costs. Using simple techniques can improve your ability to utilize Solidity while developing solid smart contracts.
