Gas optimization in DeFi: The key to reducing costs and improving efficiency In the field of decentralized finance (DeFi), users need to pay Gas fees for every transaction they make, such as token swaps, lending operations, participating in liquidity mining, etc. When mainstream public chain networks such as Ethereum are congested, Gas fees soar, which not only significantly increases users' transaction costs, but may also lead to transaction delays or even failures. In order to achieve more economical and efficient operations in the DeFi ecosystem, Gas optimization has emerged. So, what exactly is Gas optimization? How does it achieve it? And what value can it bring to DeFi participants? Core concept: Optimizing blockchain transaction resource consumption In the blockchain network, Gas is the unit that measures the computing resources required to execute smart contracts. Users pay Gas fees to incentivize miners to package transactions. Gas optimization refers to reducing the amount of Gas consumed during smart contract execution or transaction process through technical means and strategy adjustments, thereby reducing user costs and improving transaction efficiency. Its essence is the refined management of blockchain computing resources, similar to Performance optimization in traditional software development, aiming to complete the same function with fewer resources. For example, in DeFi applications, by optimizing smart contract code and reducing unnecessary computing steps, Gas consumption can be reduced, allowing users to complete transactions at a lower cost. Implementation method: Multi-dimensional technical and strategic optimization Gas optimization can be achieved from the dimensions of smart contract code optimization, trading strategy adjustment, and the use of Layer 2 solutions. At the code level, developers reduce the complexity of contract execution by simplifying code logic, reducing storage operations, and using data types reasonably. For example, avoid frequent calls to external contract functions in the contract, as each external call will increase Gas consumption; in terms of trading strategy, users can choose to trade during idle periods of the network, when Gas prices are low, or process multiple transactions in batches to reduce Gas waste caused by individual transactions; in addition, using Layer 2 solutions, such as Rollup technology, to process a large number of transactions off-chain and then submit them to the main chain, can also significantly reduce Gas costs. HashKey Exchange When providing DeFi services to users, it also pays attention to the application of Gas optimization technology to help users understand how to choose a more reasonable time for Gas fees to trade and improve investment experience. Application significance: Promote the healthy development of DeFi ecology Gas optimization is of great significance to the development of DeFi ecosystem. For ordinary users, lower Gas fees mean higher profits, and users can use the saved funds for more investment activities. For developers, DeFi applications optimized by Gas are more competitive, attracting more users to use and promoting project development. From an ecological perspective, Gas optimization helps alleviate network congestion, improve the overall performance of blockchain, make the operation of DeFi applications smoother, and attract more users and funds to enter the DeFi field. HashKey Exchange follows the trend of Gas optimization technology and explores how to apply optimization strategies to platform services to create a more economical and efficient DeFi trading environment for users. However, it should be noted that Gas optimization is not unlimited, and excessive optimization may affect the security and functional integrity of smart contracts. Therefore, caution should be exercised when conducting Gas optimization. What is HashKey Exchange? HashKey Exchange is one of the first regulated cryptocurrency exchanges in Hong Kong to obtain a license from the Securities and Futures Commission (SFC). It supports fiat currency deposits and trading in Hong Kong dollars (HKD) and US dollars (USD), offering users spot trading services for mainstream digital assets including Bitcoin (BTC), Ethereum (ETH), and Tether (USDT). The platform also provides OTC (over-the-counter) services to meet the needs of large-value asset transactions and fiat currency conversion, ensuring more flexible and private trading. To cater to the asset allocation needs of different investors, HashKey has launched the HashKey Earn channel, offering users fixed-term and demand financial products to achieve stable appreciation of crypto assets. The platform holds ISO 27001 and 27701 security certifications, employs a 98% cold wallet storage mechanism, and incorporates security measures such as two-factor authentication to provide users with a stable and reliable trading environment.
