#  Web3 开发神器：Arbitrum Stylus 智能合约全攻略

Web3 浪潮席卷全球，Arbitrum 作为以太坊二层解决方案的明星项目，以低成本和高性能赢得开发者青睐。其最新工具 Arbitrum Stylus 更是颠覆传统，让你用 Rust 语言轻松开发高效智能合约！通过 WebAssembly (WASM) 技术，Stylus 不仅大幅降低 Gas 费用，还让合约开发变得更灵活、更强大。想快速上手 Web3 开发？本文为你献上一份 Arbitrum Stylus 智能合约全攻略，从环境搭建到合约部署，手把手带你解锁 Web3 开发的无限可能！准备好了吗？让我们一起开启这场开发之旅！

本文是 Web3 开发者的入门宝典，详细讲解如何利用 Arbitrum Stylus 和 Rust 开发智能合约。内容涵盖开发环境搭建（Rust 和 Stylus CLI 安装、WASM 配置）、测试网钱包创建、项目初始化、ABI 导出、Gas 费用预估、合约部署与验证，以及合约调用和缓存优化。通过实战项目 stylus-hello-world，你将学会部署一个简单的计数器合约，并在 Arbitrum Sepolia 测试网上运行。无论你是 Web3 新手还是进阶开发者，这篇全攻略都能帮你快速掌握 Stylus 的核心技能，开启低成本、高性能的智能合约开发之旅！

## 实操

### 安装 Rust

```bash
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
```

### **安装 Stylus CLI tool**

```bash
cargo install --force cargo-stylus
```

### 添加 WASM (WebAssembly) 作为 Rust 编译器的构建目标

```bash
rustup target add wasm32-unknown-unknown
```

验证是否安装成功

```bash
cargo stylus --version
stylus 0.5.12

cargo stylus -V
stylus 0.5.12

cargo stylus --help 
Cargo subcommand for developing Stylus projects

Usage: cargo stylus <COMMAND>

Commands:
  new           Create a new Stylus project
  init          Initializes a Stylus project in the current directory
  export-abi    Export a Solidity ABI
  constructor   Print the signature of the constructor
  activate      Activate an already deployed contract [aliases: a]
  cache         Cache a contract using the Stylus CacheManager for Arbitrum chains
  check         Check a contract [aliases: c]
  get-initcode  Generate and print initcode for the contract [aliases: e]
  deploy        Deploy a contract [aliases: d]
  verify        Verify the deployment of a Stylus contract [aliases: v]
  cgen          Generate c code bindings for a Stylus contract
  replay        Replay a transaction in gdb [aliases: r]
  trace         Trace a transaction [aliases: t]
  simulate      Simulate a transaction [aliases: s]
  help          Print this message or the help of the given subcommand(s)

Options:
  -h, --help     Print help
  -V, --version  Print version
```

### **创建开发者钱包或账户**

在测试链上玩合约时，一定要用全新的空钱包（里面别放真钱）！

也就是说，测试网操作必须用零余额的新钱包，别用存过真钱的钱包！

### **初始化项目**

```bash
cargo stylus new stylus-hello-world
Cloning into '.'...
remote: Enumerating objects: 23, done.
remote: Counting objects: 100% (23/23), done.
remote: Compressing objects: 100% (18/18), done.

initialized project in: /Users/qiaopengjun/Code/Arbitrum/stylus-hello-world
```

### 查看项目目录结构

```bash
cd stylus-hello-world/

ls

```

- examples/counter.rs 使用 [ethers-rs](https://github.com/gakonst/ethers-rs) 调用智能合约的代码示意，ethers-rs 是支持跟 Ethereum 或 EVM 兼容的区块链进行交互的 Rust 库 。
- src 使用 Rust 语言编写的智能合约源码。
- Cargo.toml 项目的依赖配置。

### 导出智能合约的 ABI

Exporting the Solidity ABI interface

```bash
stylus-hello-world on  main is 📦 0.1.11 via 🦀 1.83.0 
➜ cargo stylus export-abi

interface ICounter  {
    function number() external view returns (uint256);

function addFromMsgValue() external payable;
}

}
```

在 Stylus 项目中，`cargo stylus export-abi` 命令用于导出智能合约的 ABI（应用二进制接口）文件。

NOTE: We recommend running cargo stylus cache bid 4c7701e5cdc0439d179e9ca702a8bd7904cc82fe 0 to cache your activated contract in ArbOS.
Cached contracts benefit from cheaper calls. To read more about the Stylus contract cache, see

Web3 开发神器：Arbitrum Stylus 智能合约全攻略

实操

安装 Rust

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

安装 Stylus CLI tool

cargo install --force cargo-stylus

添加 WASM (WebAssembly) 作为 Rust 编译器的构建目标

rustup target add wasm32-unknown-unknown

验证是否安装成功

cargo stylus --version
stylus 0.5.12

cargo stylus -V
stylus 0.5.12

cargo stylus --help 
Cargo subcommand for developing Stylus projects

Usage: cargo stylus &lt;COMMAND>

  new           Create a new Stylus project
  init          Initializes a Stylus project in the current directory
  export-abi    Export a Solidity ABI
  constructor   Print the signature of the constructor
  activate      Activate an already deployed contract [aliases: a]
  cache         Cache a contract using the Stylus CacheManager for Arbitrum chains

Options:
  -h, --help     Print help
  -V, --version  Print version

创建开发者钱包或账户

在测试链上玩合约时，一定要用全新的空钱包（里面别放真钱）！

也就是说，测试网操作必须用零余额的新钱包，别用存过真钱的钱包！
