Uniswap V4 发布：定制新“Hooks”功能，奖金池公布 235 万美元

Uniswap V4 发布了其为用户提供的去中心化交易平台的改进版本。这些变化旨在降低交易成本并改善流动性问题，使交易对流动性提供者有利可图。

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，它具有多项新功能和改进，旨在降低交易成本并提高流动性。

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”，它允许开发人员在流动性池中实现特定的附加功能。这些挂钩可用于添加与市场事件挂钩的可变费用或交易订单的高级形式，例如时间加权平均价格（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.

由于Hooks赋予的灵活性，可以为反向和高度专业化的交易模型的开发提供更多可能性。尽管用户只能按照应用程序开发人员的定义添加和配置 Hook，但作为回报，他们可以自行创建和安装 Hook，而无需寻求应用程序开发人员的批准。

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 中的新架构设计称为 Singleton；它解决了工厂/池结构的问题。众所周知，早期版本中存在的多个流动性池是独立运行的，并且它们需要在多步骤交易中进行多个合约交互。 Singleton 模型将所有液化资产聚合在一个合约中，交易时成本较低。初步计算表明，池化成本优化可达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.

新系统还包括“闪记”机制。这只会在交换结束时转移代币的净余额，进一步最大限度地减少天然气消耗。 Singleton架构与Hooks相结合，预计将使Uniswap V4成为最高效的去中心化交易所之一，为用户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.

在启动的同时，Uniswap Labs 与 Uniswap FND 和 Cantina 一起宣布了 DeFi 历史上最大规模的安全竞赛。竞赛于 9 月 4 日开始，耗资 235 万美元，旨在寻找新协议中的弱点。

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

该项目的目标是确保 Uniswap V4 成为链上推出的经过最多审计的合约套件

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.

该竞赛向能够识别 Uniswap V4 代码中漏洞的安全专业人士和黑客开放。获奖者是根据发现的错误的严重性和文章的质量来确定的。它强调了公司对安全性和稳定性的致力于，这将是新版本正式发布时的首要任务。

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 已经被期待了一段时间，但引起了一些有关许可的担忧。就像 V4 一样，它将根据为期四年的 BSL 发布，该 BSL 规定了其他人如何使用该代码。一些加密货币批评者很快指出，此举违背了去中心化的本质。

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

然而，许可问题对于 Uniswap Labs 来说仍然至关重要，它确保客户拥有一个安全且可扩展的交易门户。

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.

与此同时，Uniswap 代币 UNI 一直处于看涨轨迹，价格在 24 小时高点和低点分别为 6.48 美元和 6.09 美元之间波动。截至发稿时，UNI 交易价格为 6.41 美元，较支撑位上涨 2%。
