Uniswap Labs 宣布推出由 Across 協定 (ACX) 驅動的去中心化跨鏈橋

存取協議旨在解決加密貨幣市場長期存在的難題之一，即轉移資產的複雜性和高成本

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背後的公司Uniswap Labs於10月23日透過部落格文章宣布推出由Across協定（ACX）支援的去中心化跨鏈橋。 Access協議旨在解決加密貨幣市場長期存在的難題之一，即在不同區塊鏈和加密貨幣交易所之間轉移資產的複雜性和高成本。

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.

新的橋接功能將能夠為 Uniswap 的 600 萬用戶無縫、順利地橋接跨鏈。這將允許Uniswap 錢包和Uniswap Web 應用程式內的用戶在9 個與以太坊虛擬機器相容的鏈（包括Optimism、Arbitrum、Polygon 和Base）之間交換以太坊、Wrapped Bitcoin 和穩定幣（例如Tether、USD Coin 和Dai）。

The Significance of Bridging in Blockchain Networks

橋接在區塊鏈網路中的意義

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 的報告所述，在鏈之間轉移資產非常麻煩，依賴第三方橋樑，導航不熟悉的介面，並且要承受很長的交易時間。此外，不同橋接服務的安全性始終令人擔憂。

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 是一種跨鏈代幣橋樑，可以快速且廉價地將代幣從一條鏈轉移到另一條鏈，為用戶提供跨鏈交易的單點存取。它由 UMA 的樂觀預言機保護，這意味著傳輸將得到樂觀驗證，以允許在不犧牲安全性的情況下快速處理。

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.

它使用一個流動性池和競爭性中繼格局來優化資本效率。 Cross採用無滑點收費模式，因此對使用者收取的費用保持在最低限度。

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 聯合創始人兼執行長 Hart Lambur 堅稱，意圖驅動的解決方案仍然是唯一一組為用戶提供第 2 層網路之間的兩秒體驗的產品。對於金額低於 10,000 美元的交易，它們的平均處理時間為 3 秒，約佔所有 L2 橋接活動的 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.

這位創辦人補充說，它最終可以讓使用數百個 L2 的體驗感覺就像一個統一的生態系統。他設想未來無縫、一鍵跨鏈交易將成為標準。

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 層網路。 Unichain 的開發是為了平滑 DeFi 碎片化的用戶體驗，其中每個網路上的流動性與其他網路上的資金是相互隔離的。該公司將透過讓超級鏈上的用戶和開發者輕鬆獲取流動性來實現這一目標。

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.

與所有或至少大多數 L2 類似，Unichain 依賴一個非常重要的單序列匯總基礎設施區塊，負責在將 L2 交易發佈到以太坊基礎層之前對來自 L2 的交易進行排序和批次。由於 Unichain 是一個驗證網絡，因此它應該可以減輕單一定序器架構固有的中心化風險。
