Uniswap V4 發布：客製化新「Hooks」功能，獎金池公佈 235 萬美元

Uniswap V4 發布了其為用戶提供的去中心化交易平台的改進版本。這些變化旨在降低交易成本並改善流動性問題，使交易對流動性提供者有利可圖。

Uniswap V4, the latest version of the decentralized exchange platform, has been released with several new features and improvements aimed at reducing transaction costs and improving liquidity.

Uniswap V4 是去中心化交易平台的最新版本，它具有多項新功能和改進，旨在降低交易成本並提高流動性。

The new version introduces "Hooks," which allows developers to implement specific additional functionalities into Liquidity pools. These Hooks can be used to add variable fees pegged on market occurrences or superior forms of an order to trade, such as the time-weighted average price (TWAP).

新版本引入了“Hooks”，它允許開發人員在流動性池中實現特定的附加功能。這些掛鉤可用於添加與市場事件掛鉤的可變費用或交易訂單的高級形式，例如時間加權平均價格（TWAP）。

Due to the flexibility empowered by Hooks, more possibilities can be opened for the development of inversed and highly specialized trading models. Whereas users can only add and configure Hooks as defined by the application developers, in return they are allowed to create and install Hooks on their own without having to seek approval from the application developers.

由於Hooks賦予的靈活性，可以為反向和高度專業化的交易模型的開發提供更多可能性。儘管用戶只能按照應用程式開發人員的定義添加和配置 Hook，但作為回報，他們可以自行建立和安裝 Hook，而無需尋求應用程式開發人員的批准。

The new architectural design in Uniswap V4 is called the Singleton; it solves the issues with the Factory/Pool structure. The multiple liquidity pools existing in earlier versions were known to function in isolation, and they required multiple contract interactions in multi-step transactions. The Singleton model has all the liquefied assets aggregated in a single contract and these are less costly when trading. Preliminary calculations indicate that optimisation of the cost of pooling could be 99%.

Uniswap V4 中的新架構設計稱為 Singleton；它解決了工廠/池結構的問題。眾所周知，早期版本中存在的多個流動性池是獨立運行的，並且它們需要在多步驟交易中進行多個合約互動。 Singleton 模型將所有液化資產聚合在一個合約中，交易時成本較低。初步計算表明，池化成本優化可達 99%。

The new system also includes a “flash accounting” mechanism. This only transfers the net balance of tokens at the end of a swap, further minimizing gas consumption. The Singleton architecture, combined with Hooks, is expected to make Uniswap V4 one of the most efficient decentralized exchanges available, providing users with lower costs and faster transactions.

新系統還包括「閃記」機制。這只會在交換結束時轉移代幣的淨餘額，進一步最大限度地減少天然氣消耗。 Singleton架構與Hooks結合，預計將使Uniswap V4成為最高效的去中心化交易所之一，為用戶提供更低的成本和更快的交易。

Concurrent to the launch, Uniswap Labs, together with the Uniswap FND and Cantina, announced the largest security competition in the history of DeFi. The competition began on Sep 4 and involved $2.35 million to find weak points in the new protocol.

在啟動的同時，Uniswap Labs 與 Uniswap FND 和 Cantina 一起宣布了 DeFi 歷史上最大規模的安全競賽。競賽於 9 月 4 日開始，耗資 235 萬美元，旨在尋找新協議中的弱點。

The goal of this project is to ensure that Uniswap V4 becomes the most audited suite of contracts to be launched on-chain

該專案的目標是確保 Uniswap V4 成為鏈上推出的經過最多審計的合約套件

The contest is open to security professionals and hackers who can identify vulnerabilities in the Uniswap V4 code. The winners were determined by the criticality of the bugs discovered and the quality of the write-up. It emphasizes the company’s dedication to safety and stability, which will be a priority for the new version when it is officially released.

該競賽向能夠識別 Uniswap V4 程式碼中漏洞的安全專業人士和駭客開放。獲獎者是根據發現的錯誤的嚴重性和文章的品質來確定的。它強調了公司​​對安全性和穩定性的致力於，這將是新版本正式發佈時的首要任務。

Uniswap V4 has been expected for some time now but has caused some concerns regarding licensing. Just like V4, it will be released under the four-year BSL which dictates how others can use the code. Some crypto critics have been quick to point out that this move is against the decentralized nature.

Uniswap V4 已經被期待了一段時間，但引起了一些有關許可的擔憂。就像 V4 一樣，它將根據為期四年的 BSL 發布，該 BSL 規定了其他人如何使用該代碼。一些加密貨幣批評者很快指出，此舉違背了去中心化的本質。

However, the licensing issue has remained paramount to Uniswap Labs, which ensures that customers have a safe and malleable trading portal.

然而，授權問題對於 Uniswap Labs 來說仍然至關重要，它確保客戶擁有一個安全且可擴展的交易入口網站。

In the meantime, the Uniswap token UNI has been in a bullish trajectory, with the price moving between a 24-hour high and low of $6.48 and $6.09, respectively. At press time, UNI was trading at $6.41, a 2% surge from the support level.

與此同時，Uniswap 代幣 UNI 一直處於看漲軌跡，價格在 24 小時高點和低點分別為 6.48 美元和 6.09 美元之間波動。截至發稿時，UNI 交易價格為 6.41 美元，較支撐位上漲 2%。
