-**维护**: NAC开发团队  
-**创建日期**: 2026-02-18
+- Rust 1.70+
+- 操作系统: Linux, macOS, Windows
+
+## 快速开始
+
+### 1. 初始化配置
+
+```bash
+nac config init
+```
+
+### 2. 配置RPC节点
+
+```bash
+nac config set network.rpc_url http://your-nac-node:8545
+```
+
+### 3. 创建账户
+
+```bash
+nac account create
+```
+
+### 4. 查询余额
+
+```bash
+nac account balance <地址>
+```
+
+### 5. 发送交易
+
+```bash
+nac tx send <发送方地址> <接收方地址> <金额>
+```
+
+## 命令参考
+
+完整的命令参考请查看 [docs/COMMANDS.md](docs/COMMANDS.md)
+
+## NAC RPC方法
+
+完整的RPC方法列表请参考 [docs/NAC_RPC_METHODS.md](docs/NAC_RPC_METHODS.md)
+
+## 配置文件
+
+配置文件位于 `~/.nac/config.toml`，详细说明请查看 [docs/CONFIGURATION.md](docs/CONFIGURATION.md)
+
+## 安全注意事项
+
+- 私钥使用AES-256-GCM加密存储

+## 示例
+
+### 获取账户余额
+```json
+{
+  "jsonrpc": "2.0",
+  "method": "nac_account_getBalance",
+  "params": {
+    "address": "0x1234...abcd"
+  },
+  "id": 1
+}
+```
+
+### 发送交易
+```json
+{
+  "jsonrpc": "2.0",
+  "method": "nac_tx_send",
+  "params": {
+    "from": "0x1234...abcd",

+
+## 注意事项
+
+1. **不要使用以太坊方法名** - NAC是原生链，不继承ERC-20/ERC-721
+2. **使用NAC原生类型** - Address(32字节)、Hash(48字节)
+3. **遵循CBPP共识** - 所有交易需要宪法验证
+4. **支持RWA资产** - 使用ACC协议系列
+5. **集成XTZH预言机** - 汇率数据来自AI模型
