Web3 时代的到来，让以太坊区块链开发成为开发者关注的热点。Foundry 作为一款强大的 Solidity 开发工具集，凭借其命令行工具 cast，为开发者提供了查询区块链数据、调试交易和分析智能合约的高效途径。本文通过一系列实操案例，带你走进 Web3 开发的实战场景，探索如何用 Foundry 查询以太坊区块、交易详情、事件日志，并进行交易模拟，助力你在 Web3 开发中游刃有余！
本文详细介绍了 Foundry 的 cast 命令在以太坊开发中的多种应用，包括查询最新区块高度、区块详情、交易收据、Gas 单价，以及解析合约调用数据、事件签名和函数选择器等功能。通过具体案例，展示了从环境变量配置到 JSON 数据格式化，再到交易模拟执行的完整流程。文章还介绍了如何通过 cast run 调试交易调用栈，为 Web3 开发者提供实用参考，助力开发高效的去中心化应用。
通过 export ETH_RPC_URL 设置环境变量，让后续的 cast 命令自动使用该 RPC 节点，无需重复指定 --rpc-url。
