ZetaChain 网关：通往去中心化世界的统一网关

Gateway简化了跨链通用应用的开发体验，并实现了包括比特币在内的区块链网络的原生操作。

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.

开发人员现在可以在 ZetaChain 上构建通用应用程序，这些应用程序可以在任何区块链网络（包括比特币）上执行本机操作。这些应用程序可以无缝处理跨链的合约调用、消息和代币传输，从而使加密生态系统内的互操作性达到新的水平。

Key Highlights:

主要亮点：

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".

构建通用应用程序以覆盖世界各地的用户：与仅限于单个区块链的传统智能合约不同，ZetaChain EVM 上的通用应用程序可以在任何连接的区块链网络上执行跨链操作。他们可以处理来自任何链的合约调用、消息和代币传输，甚至可以在这些链上发起相应的操作。此功能允许开发人员跨不同链编排复杂的多步骤交易，这些交易可以由单个用户操作触发，而无需在多个接口之间切换或处理不同的区块链协议。 ZetaChain平台为开发者提供了自动化这些跨链交互的工具，使他们能够专注于应用程序的核心功能开发，并为最终用户提供接近“一站式执行”的链上抽象操作体验。所有操作”。

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:

网关统一了开发人员和用户体验：网关升级引入了统一的跨链接口——开发人员和用户与任何区块链上的通用应用程序进行交互的单一通用入口点。以下是 Gateway 如何使每个群体受益：

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.

开发人员获得简化、可扩展的框架：网关提供统一的 API 接口，抽象出每个区块链网络特征和协议细节的复杂性。每个区块链网络都有一个指定的网关合约或等效实体（例如 Solana 上的网关程序或比特币上的地址），提供存储代币和与通用应用程序交互的标准化方法。使用 Gateway，链上交互就像按下按钮一样简单。例如，单个用户交易可以触发 ZetaChain 上的通用应用程序，帮助其将 BNB 兑换为 ETH，然后在以太坊上购买 NFT，所有这些都一步完成。

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.

用户享受统一的链上体验：网关使用户能够在单个交易中跨链交互，而无需切换网络。从他们喜欢的区块链网络（例如比特币或以太坊），用户可以访问通用应用程序，而无需连接多个钱包或使用跨链桥。这种无缝集成有效降低了跨链费用，增强了操作安全性，并在所有支持的链上提供了统一的体验。

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 增强了 ZetaChain 上的跨链基础设施：此前，开发者需要管理独立的 TSS 地址、ERC-20 托管合约和连接器合约来实现跨链功能；现在，Gateway 将这些组件统一到一个强大的 API 接口中，为调用、存款和资产管理提供清晰一致的方法。这种统一的方式不仅简化了开发流程，还提高了跨链交易的可靠性。此外，部署在ZetaChain上的Gateway接口可以镜像到其他EVM兼容链上，提供多个区块链平台上的统一开发和用户体验。

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.

网关允许通用应用程序管理全局资产：通过网关，通用应用程序现在可以代表用户与外部区块链网络上连接的智能合约和资产实现复杂的交互。 Gateway 通过“withdrawAndCall”扩展通用智能合约来实现这一目标，“withdrawAndCall”是 ZRC-20 提款功能的扩展。开发者无需资产转移或数据加载即可发起合约调用操作，并享受内置回滚支持等好处。

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.

用户现在可以无缝访问多个链上应用程序并与之交互。换句话说，Gateway 使应用程序能够通过在 ZetaChain 上仅与 dApp 交互一次来代表最终用户聚合和优化跨链操作。使用网关的应用程序可以帮助用户无需切换网络或签署额外的交易。

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

Gateway 为链抽象建立了新标准：Gateway 升级为链抽象建立了新的通用标准，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 标准允许开发人员创建在多个区块链网络上平稳运行的 ERC-721 NFT。该标准简化了跨链交互流程，使用户和开发者能够直接在支持的链上访问和转移 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 构建的项目包括： Web3 游戏项目 Eureka 和 Moddio - Eureka 是一款基于网络构建的社交游戏，允许玩家通过铸造可交易的 NFT 来提取游戏内资产，如金币、船舶、生存物品和其他物资。任何链条。同样，虚拟世界创建项目Moddio将为在其平台上构建的开发者提供通用的NFT功能支持。有关一般 NFT 创建教程，请参阅 YouTube 视频。

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.

通用代币标准：通用代币标准将为 ZRC-20 机制提供更灵活、无需许可的替代方案，用于创建可跨链无缝转移的代币。

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.

具体来说，ZRC-20机制依赖于“锁定释放模型”，该模型要求资产在协议中列入白名单才能跨链使用。这对于像 BTC 这样的原生成熟资产来说意义重大，因为它允许用户将它们引入多资产 ZetaChain 环境。

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

相比之下，通用代币标准允许开发者定义自己的代币逻辑（例如铸造、销毁、转移）
