Uniswap Labs 宣布推出由 Across 协议 (ACX) 驱动的去中心化跨链桥

访问协议旨在解决加密货币市场长期存在的难题之一，即转移资产的复杂性和高成本

Uniswap Labs, the company behind the decentralized exchange (DEX) Uniswap, announced the launch of a decentralized cross-chain bridge powered by the Across protocol (ACX) on October 23 via a blog post. The Access protocol aims to address one of the long-standing thorns in the crypto market, which is the complexity and high cost of moving assets between different blockchains and crypto exchanges.

去中心化交易所（DEX）Uniswap背后的公司Uniswap Labs于10月23日通过博客文章宣布推出由Across协议（ACX）支持的去中心化跨链桥。 Access协议旨在解决加密货币市场长期存在的难题之一，即在不同区块链和加密货币交易所之间转移资产的复杂性和高成本。

The new bridging feature will be able to bridge cross chains seamlessly and smoothly to and for Uniswap’s six million users. This will allow users within the Uniswap Wallet and Uniswap Web App to swap Ethereum, Wrapped Bitcoin, and stablecoins such as Tether, USD Coin, and Dai across nine Ethereum Virtual Machine-compatible chains, including Optimism, Arbitrum, Polygon, and Base.

新的桥接功能将能够为 Uniswap 的 600 万用户无缝、顺利地桥接跨链。这将允许 Uniswap 钱包和 Uniswap Web 应用程序内的用户在 9 个与以太坊虚拟机兼容的链（包括 Optimism、Arbitrum、Polygon 和 Base）之间交换以太坊、Wrapped Bitcoin 和稳定币（例如 Tether、USD Coin 和 Dai）。

The Significance of Bridging in Blockchain Networks

桥接在区块链网络中的意义

As stated in Uniswap’s report, moving assets between chains has been cumbersome, relying on third-party bridges, navigating unfamiliar interfaces, and enduring long transaction times. Moreover, there is always concern about the security of different bridging services.

正如 Uniswap 的报告所述，在链之间转移资产非常麻烦，依赖第三方桥梁，导航不熟悉的界面，并且要承受很长的交易时间。此外，不同桥接服务的安全性始终令人担忧。

What feature do you want us to cook up on the Uniswap web app?

ACX is a cross-chain token bridge that makes it speedy and inexpensive to move tokens from one chain to another, offering users a single point of access for their cross-chain transactions. It is secured by the UMA’s optimistic oracle, meaning that transfers will be optimistically validated to allow for processing at speed without sacrificing security.

ACX 是一种跨链代币桥梁，可以快速且廉价地将代币从一条链转移到另一条链，为用户提供跨链交易的单点访问。它由 UMA 的乐观预言机保护，这意味着传输将得到乐观验证，以允许在不牺牲安全性的情况下快速处理。

It uses one liquidity pool and a competitive relayer landscape to optimize capital efficiency. Across applies a no-slippage fee model, thus the fees charged are kept minimal for users.

它使用一个流动性池和竞争性中继格局来优化资本效率。 Cross采用无滑点收费模式，因此对用户收取的费用保持在最低水平。

Hart Lambur, co-founder and CEO of Across, insisted the intents-powered solutions remain the only set of products offering users this two-second experience between layer-2 networks. They have an average of three seconds for transactions less than $10,000, representing roughly 99% of all L2 bridging activity.

Across 联合创始人兼首席执行官 Hart Lambur 坚称，意图驱动的解决方案仍然是唯一一组为用户提供第 2 层网络之间的两秒体验的产品。对于金额低于 10,000 美元的交易，它们的平均处理时间为 3 秒，约占所有 L2 桥接活动的 99%。

The founder added that it can finally make the experience of using hundreds of L2s feel like one unified ecosystem. He envisions a future where seamless, 1-click cross-chain transactions become the standard.

这位创始人补充说，它最终可以让使用数百个 L2 的体验感觉就像一个统一的生态系统。他设想未来无缝、一键式跨链交易将成为标准。

On Oct. 10, Uniswap introduced Unichain, its very own layer 2 network. Unichain was developed to smoothen the fragmented user experience of DeFi, wherein liquidity on each network is siloed from the capital on others. The company will do this by making liquidity access easy for both users and developers along the Superchain.

10 月 10 日，Uniswap 推出了 Unichain，它自己的第 2 层网络。 Unichain 的开发是为了平滑 DeFi 碎片化的用户体验，其中每个网络上的流动性与其他网络上的资金是相互隔离的。该公司将通过让超级链上的用户和开发者轻松获取流动性来实现这一目标。

Similar to all, or at least most of the L2s, Unichain relies on a one-sequence very important chunk of rollup infrastructure responsible for ordering and batching transactions from L2 before posting them on Ethereum’s base layer. It should mitigate the risk of centralization inherent in single sequencer architectures since Unichain is a validation network.

与所有或至少大多数 L2 类似，Unichain 依赖于一个非常重要的单序列汇总基础设施块，负责在将 L2 交易发布到以太坊基础层之前对来自 L2 的交易进行排序和批处理。由于 Unichain 是一个验证网络，因此它应该可以减轻单一定序器架构固有的中心化风险。
