ZetaChain 網關：通往去中心化世界的統一網關

Gateway簡化了跨鏈通用應用的開發體驗，並實現了包括比特幣在內的區塊鏈網路的原生操作。

Developers can now build universal applications on ZetaChain that can perform native operations on any blockchain network, including Bitcoin. These applications can seamlessly handle contract calls, messages, and token transfers across chains, enabling a new level of interoperability within the crypto ecosystem.

開發人員現在可以在 ZetaChain 上建立通用應用程序，這些應用程式可以在任何區塊鏈網路（包括比特幣）上執行本機操作。這些應用程式可以無縫處理跨鏈的合約呼叫、訊息和代幣傳輸，從而使加密生態系統內的互通性達到新的水平。

Key Highlights:

主要亮點：

Build Universal Applications to Reach Users Everywhere: Unlike conventional smart contracts that are limited to a single blockchain, universal applications on ZetaChain EVM can perform cross-chain operations on any connected blockchain network. They can handle contract calls, messages, and token transfers from any chain, and can even initiate corresponding operations on those chains. This capability allows developers to orchestrate complex multi-step transactions across different chains, which can be triggered by a single user action without having to switch between multiple interfaces or deal with different blockchain protocols. The ZetaChain platform provides developers with the tools to automate these cross-chain interactions, allowing them to focus on the core functional development of the application and provide end users with an on-chain abstract operation experience that is close to "one-stop execution of all operations".

建立通用應用程式以覆蓋世界各地的用戶：與僅限於單一區塊鏈的傳統智慧合約不同，ZetaChain EVM 上的通用應用程式可以在任何連接的區塊鏈網路上執行跨鏈操作。他們可以處理來自任何鏈的合約呼叫、訊息和代幣傳輸，甚至可以在這些鏈上發起相應的操作。此功能允許開發人員跨不同鏈編排複雜的多步驟交易，這些交易可以由單一用戶操作觸發，而無需在多個介面之間切換或處理不同的區塊鏈協議。 ZetaChain平台為開發者提供了自動化這些跨鏈互動的工具，使他們能夠專注於應用程式的核心功能開發，並為最終用戶提供接近「一站式執行」的鏈上抽像操作體驗。

Gateway Unifies Developer and User Experience: The Gateway upgrade introduces a unified cross-chain interface - a single universal entry point for developers and users to interact with universal applications on any blockchain. Here's how Gateway benefits each group:

網關統一了開發人員和用戶體驗：網關升級引入了統一的跨連結口——開發人員和用戶與任何區塊鏈上的通用應用程式互動的單一通用入口點。以下是 Gateway 如何使每個群體受益：

Developers Get a Simplified, Extensible Framework: Gateway provides a unified API interface that abstracts away the complexities of each blockchain network's characteristics and protocol details. Each blockchain network has a designated Gateway contract or equivalent entity (such as the Gateway program on Solana or the address on Bitcoin) that provides a standardized method for depositing tokens and interacting with general applications. With Gateway, on-chain interactions are as easy as pressing a button. For example, a single user transaction can trigger a universal application on ZetaChain to help it exchange BNB for ETH and then purchase NFTs on Ethereum, all in one step.

開發人員獲得簡化、可擴展的框架：網關提供統一的 API 接口，抽像出每個區塊鏈網路特徵和協議細節的複雜性。每個區塊鏈網路都有一個指定的網關合約或等效實體（例如 Solana 上的網關或比特幣上的地址），提供儲存代幣和與通用應用程式互動的標準化方法。使用 Gateway，鏈上互動就像按下按鈕一樣簡單。例如，單一用戶交易可以觸發 ZetaChain 上的通用應用程序，幫助其將 BNB 兌換為 ETH，然後在以太坊上購買 NFT，所有這些都一步完成。

Users Enjoy a Unified On-Chain Experience: Gateway enables users to interact across chains in a single transaction without switching networks. From their preferred blockchain network (such as Bitcoin or Ethereum), users can access universal applications without connecting multiple wallets or using cross-chain bridges. This seamless integration effectively reduces cross-chain fees, enhances operational security, and provides a unified experience on all supported chains.

使用者享受統一的鏈上體驗：網關使用戶能夠在單一交易中跨鏈交互，而無需切換網路。從他們喜歡的區塊鏈網路（例如比特幣或以太坊），用戶可以存取通用應用程序，而無需連接多個錢包或使用跨鏈橋。這種無縫整合有效降低了跨鏈費用，增強了操作安全性，並在所有支援的鏈上提供了統一的體驗。

Gateway Enhances Cross-Chain Infrastructure on ZetaChain: Previously, developers needed to manage independent TSS addresses, ERC-20 escrow contracts, and connector contracts to achieve cross-chain functionality; now, Gateway unifies these components into a single powerful API interface, providing a clear and consistent approach for calls, deposits, and asset management. This unified approach not only simplifies the development process, but also improves the reliability of cross-chain transactions. In addition, the Gateway interface deployed on ZetaChain can be mirrored on other EVM-compatible chains, providing a unified development and user experience on multiple blockchain platforms.

Gateway 增強了 ZetaChain 上的跨鏈基礎架構：在此之前，開發者需要管理獨立的 TSS 位址、ERC-20 託管合約和連接器合約來實現跨鏈功能；現在，Gateway 將這些元件統一到一個強大的 API 介面中，為呼叫、存款和資產管理提供清晰一致的方法。這種統一的方式不僅簡化了開發流程，也提高了跨鏈交易的可靠性。此外，部署在ZetaChain上的Gateway介面可以鏡像到其他EVM相容鏈上，提供多個區塊鏈平台上的統一開發和使用者體驗。

Gateway Allows Universal Applications to Manage Global Assets: With Gateway, general-purpose applications can now implement complex interactions with connected smart contracts and assets on external blockchain networks on behalf of users. Gateway achieves this goal by extending general-purpose smart contracts through "withdrawAndCall", an extension of ZRC-20 's withdrawal function. Developers can initiate contract call operations without asset transfer or data load, and enjoy benefits such as built-in rollback support.

網關允許通用應用程式管理全域資產：透過網關，通用應用程式現在可以代表用戶與外部區塊鏈網路上連接的智慧合約和資產實現複雜的互動。 Gateway 透過「withdrawAndCall」擴展通用智能合約來實現這一目標，「withdrawAndCall」是 ZRC-20 提現功能的擴展。開發者無需資產轉移或資料載入即可發起合約呼叫操作，並享受內建回溯支援等好處。

Users can now seamlessly access and interact with multiple on-chain applications. In other words, Gateway enables an application to aggregate and optimize cross-chain operations on behalf of end users by interacting with dApps only once on ZetaChain. Applications using Gateway can help users without switching networks or signing additional transactions.

用戶現在可以無縫存取多個鏈上應用程式並與之互動。換句話說，Gateway 使應用程式能夠透過在 ZetaChain 上僅與 dApp 互動一次來代表最終用戶聚合和優化跨鏈操作。使用網關的應用程式可以幫助用戶無需切換網路或簽署額外的交易。

Gateway Establishes New Standards for Chain Abstraction: The Gateway upgrade enables a new common standard for chain abstraction, including:

Gateway 為鏈結抽象建立了新標準：Gateway 升級為鏈結抽象建立了新的通用標準，包括：

Universal NFT: The universal NFT standard on ZetaChain allows developers to create ERC-721 NFTs that run smoothly on multiple blockchain networks. The standard simplifies the cross-chain interaction process, enabling users and developers to directly access and transfer NFTs on supported chains.

通用 NFT：ZetaChain 上的通用 NFT 標準允許開發人員創建在多個區塊鏈網路上平穩運行的 ERC-721 NFT。該標準簡化了跨鏈互動流程，使用戶和開發者能夠直接在支援的鏈上存取和轉移 NFT。

Projects built with universal NFTs include: Web3 gaming projects Eureka and Moddio - Eureka, a social game built on the web, allows players to extract in-game assets such as gold currency, ships, survival items, and other supplies by minting tradable NFTs on any chain. Similarly, virtual world creation project Moddio will provide universal NFT functionality support for developers building on its platform. See the YouTube video for a general NFT creation tutorial.

使用通用NFT 構建的項目包括： Web3 遊戲項目Eureka 和Moddio - Eureka 是一款基於網絡構建的社交遊戲，允許玩家透過鑄造可交易的NFT 來提取遊戲內資產，如金幣、船舶、生存物品和其他物資。同樣，虛擬世界創建專案Moddio將為在其平台上建置的開發者提供通用的NFT功能支援。有關一般 NFT 建立教程，請參閱 YouTube 影片。

Universal Token Standard: The universal token standard will provide a more flexible and permissionless alternative to the ZRC-20 mechanism for creating tokens that can be seamlessly transferred across chains.

通用代幣標準：通用代幣標準將為 ZRC-20 機制提供更靈活、無需許可的替代方案，用於創建可跨鏈無縫轉移的代幣。

Specifically, the ZRC-20 mechanism relies on a “lock-release model” that requires assets to be whitelisted in the protocol before they can be used across chains. This is significant for native, mature assets like BTC, as it allows users to introduce them into the multi-asset ZetaChain environment.

具體來說，ZRC-20機制依賴於“鎖定釋放模型”，該模型要求資產在協議中列入白名單才能跨鏈使用。這對於像 BTC 這樣的原生成熟資產來說意義重大，因為它允許用戶將它們引入多資產 ZetaChain 環境。

In contrast, the Universal Token Standard allows developers to define their own token logic (such as minting, destruction, transfer)

相較之下，通用代幣標準允許開發者定義自己的代幣邏輯（例如鑄造、銷毀、轉移）
