🔐 下一代Web3钱包 - 无助记词 + Passkey生物识别 + TEE硬件安全

AirAccount通过创新的**"意图-安全分离"**架构，让Web3钱包既安全又易用：

• 无助记词: Web2社交账户 + Passkey生物识别，彻底摆脱助记词
• TEE硬件安全: 基于ARM TrustZone的物理级安全隔离
• 意图驱动: 用户表达简单意图，TEE执行复杂的安全检查

AirAccount是一个完整的TEE硬件钱包解决方案，运行在Raspberry Pi 5的OP-TEE环境上。所有私钥存储在TEE安全存储中，交易签名通过生物识别验证，并由DVT网络和链上智能合约双重验证。

"让Web3像Web2一样简单，让钱包像银行一样安全"

🔥 用户体验: 无需学习助记词，用Google账户+指纹就能拥有Web3钱包
🛡️ 企业安全: 基于TEE硬件的银行级安全，支持Account Abstraction
🚀 开发友好: 完整的TypeScript SDK，一行代码集成钱包功能

Our work is heavily based on the official Teaclave and OP-TEE projects. We use the official incubator-teaclave-trustzone-sdk as a submodule to ensure we can stay up-to-date with the latest developments. The eth_wallet example within the SDK serves as a foundational reference for our Trusted Application development.

Please refer to the Planning Document for the full development roadmap and technical details. The first step is to set up the development environment as described in V0.1.

AAStar 使用 Apache Teaclave 开源项目来构建 TEE-Account，这是一个为社区打造的、基于 TEE 的硬件钱包。我们在树莓派5上通过 OP-TEE 运行 TEE-Account。该账户将您的私钥安全地存储在 OP-TEE 的安全存储区中，并使用经过验证的指纹签名来签署交易。所有签名都将由 DVT 和链上账户合约进行验证。

TEE-Account 是我们 AirAccount 项目的一部分。

本仓库是一个包含 AirAccount TEE Web3 账户系统所有核心组件的单一代码库 (Monorepo)。关于详细的技术规划和发展路线图，请参阅规划文档。

我们的工作在很大程度上基于官方的 Teaclave 和 OP-TEE 项目。我们使用官方的 incubator-teaclave-trustzone-sdk 作为 Git 子模块，以确保我们能够与最新的开发进展保持同步。该 SDK 中的 eth_wallet 示例是我们开发可信应用（TA）的基础参考。

请参阅规划文档以获取完整的开发路线图和技术细节。第一步是按照 V0.1 中的描述来搭建开发环境。

一个典型的TEE应用开发模型如下：

我的客户端应用 (Client Application, CA) 是一个运行在普通世界 (Normal World) 标准操作系统（如Ubuntu、Android）上的常规程序。它可以由Rust、C++或任何其他主流语言开发，负责处理应用的通用业务逻辑，例如用户界面、网络通信或数据处理。

当我的CA需要执行安全敏感操作（例如使用私钥进行签名、解密关键数据）时，它不会自己处理。而是通过链接一个标准的TEE客户端SDK (TEE Client API) 库，调用特定的API。

这个API调用并非普通的函数调用，它会触发一次硬件层面的世界切换，从不安全的普通世界进入到由ARM TrustZone技术硬件强制隔离的安全世界 (Secure World)。

在安全世界里，运行着一个独立的、轻量级的、高安全性的可信操作系统 (TEE OS，例如OP-TEE)。我的可信应用 (Trusted Application, TA) 正是在这个TEE OS的管理下执行。TA和CA是运行在两个完全隔离的并行系统中的，彼此绝对不信任，它们之间唯一的沟通桥梁就是这个由硬件保护的、定义严格的API通道。

这个模型完美地诠释了**"硬件钱包"**的理念：CA构建交易、与外界通信，但私钥的存储和使用被严格限制在TA内部。私钥永远不会离开安全世界，极大地降低了被窃取的风险。

在开发过程中，QEMU扮演的角色是模拟一台支持TrustZone的完整ARM计算机，它能够同时运行"普通世界"（Ubuntu + CA）和"安全世界"（OP-TEE OS + TA）这两个并行的操作系统。这使得我们可以在没有物理开发板的情况下，方便地进行端到端的编译、运行和调试。
