Web3j

Web3j 是一个 Java 和 Android 库，旨在将应用与以太坊区块链客户端集成。它提供了一个用于读取链上数据和提交交易的 JSON-RPC 客户端、一个从合约定义创建原生 Java 代码的智能合约封装器生成器，以及一个用于处理加密密钥和签署交易的程序化钱包管理器。

该项目以其基于模板的封装器生成系统而著称，该系统允许与链上合约进行类型安全的交互。它还包含一个专门的工具集，用于通过域名服务解析将人类可读的域名转换为加密地址。

该库涵盖了广泛的功能，包括用于区块链查询的异步执行、加密密钥管理，以及用于分析合约行为的虚拟机执行调试。它还提供了一个基于提供商的连接模型来抽象网络传输，以及用于项目引导的命令行工具。
