## Uniswap V4: Leading the revolutionary upgrade of the DeFi new era

[Uniswap](/price/uniswap-uni) V4 was officially launched in February 2025, marking a new era for decentralized exchanges (DEX). As one of the most popular DEXs in the Ethereum ecosystem, Uniswap V4 has introduced a series of innovative features while maintaining its core strengths, greatly enhancing user experience and trading efficiency. This upgrade not only optimizes gas fees but also brings unprecedented flexibility, injecting new vitality into the DeFi space.

The most significant feature of Uniswap V4 is the introduction of a contract logic called Hooks. These Hooks allow developers to build custom logic for pools, swaps, fees, and LP positions, greatly enhancing the protocol's scalability. For example, developers can create dynamic fee structures or automated liquidity management systems, which were not possible in previous versions. This flexibility not only provides users with more options but also paves the way for innovation in the entire DeFi ecosystem.

Another important improvement is the significant reduction in gas fees. Uniswap V4 adopts a singleton contract design, reducing the cost of creating new liquidity pools by up to 99.99%. This change makes it easier for small projects and emerging tokens to list on Uniswap, promoting diversity and vitality in the entire ecosystem. In addition, the gas costs of multi-hop swaps have also been optimized, providing users with a more economical trading experience.

Uniswap V4 also introduces native ETH support, which means users can trade directly with ETH without having to wrap it into WETH first. This not only simplifies the trading process but also saves users additional gas fees. For users who frequently trade with ETH, this is a significant improvement.

To enhance security and transparency, Uniswap V4 has undergone unprecedented audits and testing. This includes nine independent audits, a $2.35 million security bug bounty, and a bug bounty program of up to $15.5 million. These measures ensure that V4 is launched with high security, providing users with more protection.

The launch of Uniswap V4 is not just a technical upgrade, but also a major leap forward for the DeFi ecosystem. It provides developers with unprecedented space for innovation, while also bringing users lower costs and a better experience. With the widespread adoption of V4, we have reason to believe that it will drive DeFi towards a more mature and efficient direction, attracting more users and capital into this thriving field.

## Mastering Uniswap V4: A Beginner's Guide to Easy Operation

For new users who have just started using decentralized exchanges, the powerful features of Uniswap V4 may seem a bit complex. However, in reality, V4 is designed with a focus on user-friendliness, making it easy for even beginners to get started. This Uniswap tutorial will provide you with a detailed guide on how to swap tokens, provide liquidity, and utilize new features on Uniswap V4.

First, token exchange is the most basic and commonly used operation. Users need to connect their own <a href="/ja/web3" target="_blank" class="blog_inner_link">Web3</a> wallet (such as Gate.io [Web3](/web3)(Wallet) to the Uniswap interface. Select the token pair to be exchanged, enter the desired amount to be exchanged, and the system will automatically calculate the quantity of the other token that can be obtained. It is worth noting that V4 supports native ETH transactions, eliminating the need to wrap ETH into WETH, greatly simplifying the operation process. After confirming the transaction details, click the 'Swap' button to complete the exchange. The entire process is intuitive and simple, even first-time users can easily complete it.

Providing liquidity is an important way to participate in the DeFi ecosystem. In V4, this process becomes more flexible. Users can choose the token pairs they want to provide liquidity for, set price ranges, and fees. The innovation of V4 is that users can choose to use preset Hooks to optimize their liquidity strategy. For example, they can choose Hooks that automatically reinvest earnings or dynamically adjust price ranges. Although these functions may sound complex, Uniswap's interface design makes it exceptionally simple to choose and use these advanced features.

For users who want to delve into the new features of V4, Uniswap provides detailed tutorials and documentation. For example, how to use flash loan functionality to perform complex multi-step trades, or how to utilize the new sub_script_ion feature to track one's liquidity positions. Although these advanced features are powerful, Uniswap's design philosophy is to make them easy to understand and use for ordinary users as well.

In order to help users better understand and use these features, Uniswap has also launched a series of interactive tutorials and simulated trading environments. These tools allow users to familiarize themselves with the various functions and operation processes of V4 without using real funds. For beginners, this is a safe and efficient way to learn.

Overall, despite the introduction of many innovative features in Uniswap V4, its core operations still maintain a simple and intuitive nature. With a carefully designed user interface and comprehensive educational resources, Uniswap ensures that even beginners can quickly get started and fully utilize the powerful features of V4. As users gradually become familiar with these new features, they will be able to participate more deeply in the DeFi ecosystem, enjoying the convenience and opportunities brought by decentralized exchanges.

## Conclusion

Uniswap V4 leads DeFi into a new era, with innovative features bringing unprecedented experiences to users. Customizable Hooks, singleton contracts, and native ETH support significantly improve trading efficiency and reduce costs. Simplified operation processes make it easy for newcomers to get started, sparking the vigorous development of innovative applications in the DeFi ecosystem. Uniswap V4 is reshaping the decentralized trading landscape, propelling DeFi towards a broader future.
