2 Signature
How To Sign Message
How To GET Your L2 Private Key
To sign messages on Layer 2, you need to obtain your L2 private key. This key is used to generate signatures that authorize various actions on the platform.
How To GET Your L2 Private Key
Warning: Keep your private key secure and never share it with anyone. Anyone with access to your private key can sign messages on your behalf.
Signature Algorithm
The signature algorithm used is Ecdsa (Elliptic Curve Digital Signature Algorithm). This algorithm ensures that signatures are secure and verifiable.
L2Signature for Operations (e.g., Order, Transfer, Withdraw): This will use Pedersen hash for signing. However, this hash computation will consume significantly more CPU resources.

Signature Construction Guide
This section provides detailed instructions on constructing signatures for various actions on the platform.
Withdrawal Signature
Used to authorize withdrawing assets from Layer 2 to an Ethereum address.
Parameters
assetIdCollateral - Asset ID for the collateral token from meta_data.coinList.starkExAssetId
positionId - User's account ID in Layer 2
ethAddress - Destination Ethereum address for withdrawal
nonce - Unique transaction identifier to prevent replay attacks
expirationTimestamp - Unix timestamp when signature expires
amount - Amount to withdraw in base units
Calculation
The following TypeScript function constructs the withdrawal message for signing:
Copy
// Construct withdrawal message for signing
function getWithdrawalToAddressMsg({
assetIdCollateral,
positionId,
ethAddress,
nonce,
expirationTimestamp,
amount
}) {
// Pack parameters into 256-bit words
const w1 = assetIdCollateral;
let w5 = BigInt(withdrawalToAddress); // Constant identifier
w5 = (w5 << 64) + BigInt(positionId);
w5 = (w5 << 32) + BigInt(nonce);
w5 = (w5 << 64) + BigInt(amount);
w5 = (w5 << 32) + BigInt(expirationTimestamp);
w5 = w5 << 49;
// Calculate Pedersen hash
return pedersen([
pedersen([w1, ethAddress]),
w5.toString(16)
]);

Limit Order Signature
Used to authorize a limit order for perpetual trading.
Parameters
assetIdSynthetic - Synthetic asset ID from meta_data.contractList.starkExSyntheticAssetId
assetIdCollateral - Collateral asset ID from meta_data.coinList.starkExAssetId
isBuyingSynthetic - true for buy orders, false for sell orders
assetIdFee - Fee token asset ID from meta_data.coinList.starkExAssetId
amountSynthetic - Amount of synthetic asset
amountCollateral - Amount of collateral asset

function getLimitOrderMsg({
assetIdSynthetic,
assetIdCollateral,
isBuyingSynthetic,
assetIdFee,
amountSynthetic,
amountCollateral,
maxAmountFee,

// Determine sell/buy assets based on order side
const [assetIdSell, assetIdBuy] = isBuyingSynthetic
? [assetIdCollateral, assetIdSynthetic]
: [assetIdSynthetic, assetIdCollateral];
const [amountSell, amountBuy] = isBuyingSynthetic
? [amountCollateral, amountSynthetic]
: [amountSynthetic, amountCollateral];
// Pack order data into 256-bit words

Authentication
Authentication is crucial for ensuring that only authorized users can access private APIs. This document outlines the authentication mechanisms used for public and private APIs.
Public API
Public APIs do not require authentication. These interfaces are accessible to anyone without the need for any credentials.
Copy
No authentication is required for public interfaces.
Private API
Private APIs require authentication to ensure that only authorized users can access them. Authentication is achieved using custom headers that include a timestamp and a signature.
Auth Header
The following headers must be included in the request to authenticate access to private APIs:
Name
Location
Type
Required
Description
X-edgeX-Api-Timestamp
header
string
must
The timestamp when the request was made. This helps prevent replay attacks.
X-edgeX-Api-Signature
header
string
must
The signature generated using the private key and request details.
CURL Examble
Copy
curl --location --request GET 'https://pro.edgex.exchange/api/v1/private/account/getPositionTransactionPage?filterTypeList=SETTLE_FUNDING_FEE&size=10&accountId=544159487963955214' \
--header 'X-edgeX-Api-Signature: 06d28020763542c0afc296dc8743797c6fda8ea9727745b57b671f70326dfed6077cd******************************aff3162e39d05d9df1c3ddf9648650382d6e62ff1076b14c0e6c687088d3917d8490e5412a080a6e9ea940c720ddd' \
--header 'X-edgeX-Api-Timestamp: 1736313025024'
Signature Elements
The signature is generated using the following elements:
Signature Element
Description
X-edgeX-Api-Timestamp
The timestamp when the request was made. This is retrieved from the request header.
Request Method (Uppercase)
The HTTP method of the request, converted to uppercase (e.g., GET, POST).
Request Path
The URI path of the request (e.g., /api/v1/resource).
Request Parameter/Body
The query parameters or request body, sorted alphabetically.
Request Parameter To Signature Content
The request parameters are concatenated into a single string that forms the signature content. This string includes the timestamp, HTTP method, request path, and sorted query parameters or request body, ensuring the integrity and authenticity of the request.
For example, the following request parameters are concatenated into a single string:
1735542383256GET/api/v1/private/account/getPositionTransactionPageaccountId=543429922991899150&filterTypeList=SETTLE_FUNDING_FEE&size=10
Generate Signature Java Example
Below is a Java implementation of the Ecdsa signature algorithm. This example demonstrates how to sign a message using a private key.
Private API Auth Signature: This is used for authentication. We do not want the hash computation to consume excessive CPU resources. Therefore, this will use SHA3 to hash the request body string before signing.

Request Body To Body String Code Example
The following Java code example demonstrates how to convert a JSON request body into a sorted string format suitable for signature generation:
Copy

import java.util.ArrayList;
import java.util.List;
import java.util.TreeMap;

private static final String EMPTY_STRING = "";
private static String getValue(JsonElement valueJson) {
if (valueJson.isJsonNull()) {
return EMPTY_STRING;
} else if (valueJson.isJsonPrimitive()) {
return valueJson.getAsString();
} else if (valueJson.isJsonArray()) {
JsonArray valueArray = valueJson.getAsJsonArray();
if (valueArray.isEmpty()) {
return EMPTY_STRING;
}
List<String> values = new ArrayList<>();
for (JsonElement itemValue : valueArray) {
values.add(getValue(itemValue));
}
return String.join("&", values);
} else if (valueJson.isJsonObject()) {
TreeMap<String, String> sortedDataMap = new TreeMap<>();

}
return sortedDataMap.keySet().stream()
.map(key -> key + "=" + sortedDataMap.get(key))
.collect(Collectors.joining("&"));
}
return EMPTY_STRING;
}
}

```
## Quick Start
```python
import asyncio
import os
from edgex_sdk import Client, OrderSide
async def main():
# Create a new client
client = Client(
base_url="https://pro.edgex.exchange", # Use https://testnet.edgex.exchange for testnet
account_id=12345, # Your account ID
stark_private_key="your-stark-private-key" # Your private key
)
# Get server time
server_time = await client.get_server_time()
print(f"Server Time: {server_time}")
# Get exchange metadata
metadata = await client.get_metadata()
print(f"Available contracts: {len(metadata.get('data', {}).get('contractList', []))}")
# Get account assets
assets = await client.get_account_asset()
print(f"Account Assets: {assets}")
# Get account positions
positions = await client.get_account_positions()
print(f"Account Positions: {positions}")
# Get 24-hour market data for BNB2USDT (contract ID: 10000004)
quote = await client.get_24_hour_quote("10000004")
print(f"BNB2USDT Price: {quote}")
# Create a limit order (uncomment to place real order)
# order = await client.create_limit_order(
# contract_id="10000004", # BNB2USDT
# size="0.01",
# price="600.00",
# side=OrderSide.BUY
# )
# print(f"Order created: {order}")
# Run the async function
asyncio.run(main())
```
## Architecture
The SDK is organized into modules that correspond to the EdgeX API structure:
```
edgex_sdk/
├── __init__.py
├── client.py # Main client

## WebSocket Support
The SDK provides a WebSocket manager for handling real-time data:
```python
import asyncio
from edgex_sdk import WebSocketManager
async def main():
# Create a WebSocket manager
ws_manager = WebSocketManager(
base_url="wss://quote.edgex.exchange", # Use wss://quote-testnet.edgex.exchange for testnet
account_id=12345,
stark_pri_key="your-stark-private-key"
)
# Define message handlers
def ticker_handler(message):
print(f"Ticker Update: {message}")
def kline_handler(message):
print(f"K-line Update: {message}")
# Connect to public WebSocket for market data
ws_manager.connect_public()
# Subscribe to real-time updates for BNB2USDT (contract ID: 10000004)
ws_manager.subscribe_ticker("10000004", ticker_handler)
ws_manager.subscribe_kline("10000004", "1m", kline_handler)
# Connect to private WebSocket for account updates
ws_manager.connect_private()
# Wait for updates
await asyncio.sleep(30)
# Disconnect all connections
ws_manager.disconnect_all()
asyncio.run(main())
```
## Signing Adapters
The SDK provides a flexible signing mechanism through signing adapters. **StarkExSigningAdapter is used by default**, so you don't need to explicitly create one:
```python
from edgex_sdk import Client
# Create a client (uses StarkExSigningAdapter by default)
client = Client(
base_url="https://pro.edgex.exchange", # Use https://testnet.edgex.exchange for testnet
account_id=12345,
stark_private_key="your-stark-private-key"
)
```
If you need to use a custom signing adapter, you can still provide one:
```python
from edgex_sdk import Client, StarkExSigningAdapter
# Create a custom signing adapter (optional)
signing_adapter = StarkExSigningAdapter()
# Create a client with a custom signing adapter
client = Client(
base_url="https://pro.edgex.exchange", # Use https://testnet.edgex.exchange for testnet
account_id=12345,
stark_private_key="your-stark-private-key",
signing_adapter=signing_adapter
)
```
The SDK includes the following signing adapters:
- **StarkExSigningAdapter** (default): Full implementation using StarkWare cryptographic operations for production use
You can also create your own signing adapter by implementing the `SigningAdapter` interface if you need custom cryptographic operations.
## Error Handling
The SDK provides proper error handling for API requests:
```python
import asyncio
from edgex_sdk import Client, OrderSide
async def main():
client = Client(
base_url="https://pro.edgex.exchange", # Use https://testnet.edgex.exchange for testnet
account_id=12345,
stark_private_key="your-stark-private-key"
)
try:
# Create a limit order for BNB2USDT
order = await client.create_limit_order(
contract_id="10000004", # BNB2USDT
size="0.01",
price="600.00",
side=OrderSide.BUY
)
print(f"Order created: {order}")
# Cancel the order
from edgex_sdk import CancelOrderParams
cancel_params = CancelOrderParams(
order_id=order.get("data", {}).get("orderId")
)
cancel_result = await client.cancel_order(cancel_params)
print(f"Order cancelled: {cancel_result}")
except ValueError as e:
print(f"Failed to create/cancel order: {str(e)}")
except Exception as e:
print(f"Unexpected error: {str(e)}")
asyncio.run(main())
```
## Pagination
Many API endpoints support pagination:
```python
import asyncio
from edgex_sdk import Client, GetActiveOrderParams
async def main():
client = Client(
base_url="https://pro.edgex.exchange", # Use https://testnet.edgex.exchange for testnet
account_id=12345,
stark_private_key="your-stark-private-key"
)
# Create pagination parameters
params = GetActiveOrderParams(
size="10",
offset_data=""
)
# Get active orders
orders = await client.get_active_orders(params)
print(f"Active orders: {orders}")
# Get next page if available
if orders.get("data", {}).get("hasNext"):
params.offset_data = orders.get("data", {}).get("offsetData")
next_page = await client.get_active_orders(params)
print(f"Next page: {next_page}")
asyncio.run(main())
```
## API Examples
### Market Data
```python
from edgex_sdk import Client, GetKLineParams, GetOrderBookDepthParams
# Get 24-hour market quotes for BNB2USDT (contract ID: 10000004)
quote = await client.get_24_hour_quote("10000004")
print(f"Current price: {quote}")
# Get K-line data for BTCUSDT (contract ID: 10000001)
kline_params = GetKLineParams(
contract_id="10000001", # BTCUSDT
interval="1m",
size="10"
)
klines = await client.quote.get_k_line(kline_params)
print(f"K-lines: {klines}")
# Get order book depth for ETHUSDT (contract ID: 10000002)
depth_params = GetOrderBookDepthParams(
contract_id="10000002", # ETHUSDT
limit=10
)
depth = await client.quote.get_order_book_depth(depth_params)
print(f"Order book: {depth}")
```
### Account Management
```python
# Get account assets
assets = await client.get_account_asset()
print(f"Account assets: {assets}")
# Get account positions
positions = await client.get_account_positions()
print(f"Positions: {positions}")
# Get position transactions
from edgex_sdk import GetPositionTransactionPageParams
tx_params = GetPositionTransactionPageParams(
size="10",
offset_data=""
)
transactions = await client.account.get_position_transaction_page(tx_params)
print(f"Transactions: {transactions}")
```
### Order Management
```python
from edgex_sdk import OrderSide, CreateOrderParams, CancelOrderParams
# Create a limit order for BNBUSDT
order = await client.create_limit_order(
contract_id="10000004", # BNBUSDT
size="0.01",
price="600.00",
side=OrderSide.BUY
)
print(f"Order created: {order}")
# Get maximum order size for BNBUSDT
max_size = await client.get_max_order_size("10000004", 600.00)
print(f"Max order size: {max_size}")
# Cancel an order
cancel_params = CancelOrderParams(
order_id=order.get("data", {}).get("orderId")
)
cancel_result = await client.cancel_order(cancel_params)
print(f"Order cancelled: {cancel_result}")
```
### Contract IDs
EdgeX uses numeric contract IDs instead of symbol-based identifiers. Here are some common contract mappings:
| Contract ID | Symbol | Tick Size |
|-------------|---------------|-----------|
| 10000001 | BTCUSDT | 0.1 |
| 10000002 | ETHUSDT | 0.01 |
| 10000003 | SOLUSDT | 0.01 |
To get the complete list of available contracts:
```python
metadata = await client.get_metadata()
contracts = metadata.get("data", {}).get("contractList", [])
for contract in contracts:
print(f"ID: {contract['contractId']} - {contract['contractName']}")
```
For more detailed examples, please refer to the [examples](examples) directory.

# EdgeX Python SDK Examples
This directory contains examples demonstrating how to use the EdgeX Python SDK.
## Prerequisites
Before running the examples, make sure you have installed the EdgeX Python SDK:
```bash
pip install edgex-python-sdk
```
Or, if you're working with the source code:
```bash
cd edgex-python-sdk
pip install -e .
```
## Environment Variables
The examples use the following environment variables:
- `EDGEX_BASE_URL`: Base URL for HTTP API endpoints (e.g., "https://pro.edgex.exchange" for production, "https://testnet.edgex.exchange" for testnet)
- `EDGEX_WS_URL`: Base URL for WebSocket endpoints (e.g., "wss://quote.edgex.exchange" for production, "wss://quote-testnet.edgex.exchange" for testnet)
- `EDGEX_ACCOUNT_ID`: Your account ID
- `EDGEX_STARK_PRIVATE_KEY`: Your stark private key
You can set these variables in your environment or create a `.env` file in the examples directory:
```
EDGEX_BASE_URL=https://pro.edgex.exchange # Use https://testnet.edgex.exchange for testnet
EDGEX_WS_URL=wss://quote.edgex.exchange # Use wss://quote-testnet.edgex.exchange for testnet
EDGEX_ACCOUNT_ID=12345
EDGEX_STARK_PRIVATE_KEY=your-stark-private-key
```
## Examples
### Basic Usage
The `basic_usage.py` example demonstrates the basic functionality of the SDK:
- Creating a client
- Getting server time and metadata
- Getting account assets and positions
- Getting market data (K-lines, order book depth)
- Creating orders (commented out to avoid actual order creation)
- Using WebSockets for real-time data
To run the example:
```bash
python basic_usage.py
```
### Advanced Usage
The `advanced_usage.py` example demonstrates more advanced features of the SDK:
- Order management (creating and canceling orders)
- WebSocket integration with proper handlers
- Error handling
- Pagination
- Using a trader class to encapsulate functionality
To run the example:
```bash
python advanced_usage.py
```
## Contract IDs
EdgeX uses numeric contract IDs instead of symbol-based identifiers. Here are some common contract mappings:
| Contract ID | Symbol | Tick Size |
|-------------|---------------|-----------|
| 10000001 | BTCUSDT | 0.1 |
| 10000002 | ETHUSDT | 0.01 |
| 10000003 | SOLUSDT | 0.01 |
| 10000004 | BNBUSDT | 0.01 |
To get the complete list of available contracts:
```python
metadata = await client.get_metadata()
contracts = metadata.get("data", {}).get("contractList", [])
for contract in contracts:
print(f"ID: {contract['contractId']} - {contract['contractName']}")
```
## Notes
- The examples include order creation code that is commented out to avoid creating actual orders. Uncomment this code if you want to create real orders.
- The WebSocket examples will run for a short time and then disconnect. Adjust the sleep time if you want to receive more updates.
- The examples use asyncio for asynchronous operations. Make sure you're using Python 3.7 or later.
- All examples use numeric contract IDs (e.g., "10000001" for BTCUSDT) as required by the EdgeX API.
- For order book depth queries, valid limit values are 15 or 200.
## Customization
Feel free to modify the examples to suit your needs. Some ideas:
- Implement a trading strategy
- Add more error handling
- Implement a command-line interface
- Create a web interface using a framework like Flask or FastAPI
- Add logging to a file
- Add more sophisticated order management
## Troubleshooting
If you encounter issues:
1. Check that your environment variables are set correctly
2. Verify that you have the latest version of the SDK
3. Check the EdgeX API documentation for any changes
4. Look for error messages in the console output
5. Try with a smaller subset of functionality to isolate the issue

- 少量 **ETH**(约 0.01-0.05 ETH)用于支付 Gas 费用
### 钱包要求
- 一个支持 EVM 的钱包,推荐:
- **MetaMask**(浏览器插件)
- **Rabby Wallet**(更专业的交易钱包)
---
## 安装 Bun 运行环境
ritmex-bot 使用 **Bun** 作为运行环境。Bun 是一个快速的 JavaScript 运行时。
### macOS / Linux 安装
打开终端,输入以下命令:
```bash
curl -fsSL https://bun.sh/install | bash
```
安装完成后,**关闭并重新打开终端**,然后验证安装:
```bash
bun -v
```
如果显示版本号(如 `1.2.x`),说明安装成功。
### Windows 安装
**方法一:使用 PowerShell(推荐)**
以管理员身份打开 PowerShell,输入:
```powershell
powershell -c "irm bun.sh/install.ps1 | iex"
```
**方法二:使用 WSL(更稳定)**
1. 先安装 WSL:在 PowerShell 中运行 `wsl --install`
2. 重启电脑
3. 打开 WSL 终端,按照 Linux 方式安装 Bun
---
## 下载并安装 ritmex-bot
### 方法一:使用 Git(推荐)
```bash
# 克隆代码仓库
git clone https://github.com/discountry/ritmex-bot.git
# 进入项目目录
cd ritmex-bot
# 安装依赖
bun install
```
### 方法二:直接下载 ZIP
1. 访问 https://github.com/discountry/ritmex-bot
2. 点击绿色的 "Code" 按钮
3. 选择 "Download ZIP"
4. 解压下载的文件
5. 在终端中进入解压后的目录
6. 运行 `bun install`
---
## 在 Nado 创建账户并入金
### 步骤 1:连接钱包
1. 访问 Nado 官网:https://app.nado.xyz
2. 点击右上角的 **"Connect Wallet"**
3. 选择你的钱包(如 MetaMask)
4. 在钱包中确认连接
### 步骤 2:添加 Ink 网络到钱包
Nado 运行在 Ink L2 网络上,你需要先添加这个网络:
**自动添加方式:**
1. 访问 https://chainlist.org/
2. 搜索 "Ink"
3. 点击 "Add to MetaMask"
**手动添加方式:**
在钱包设置中添加自定义网络,填写以下信息:
| 参数 | 值 |
|------|-----|
| 网络名称 | INK |
| RPC URL | https://rpc-gel.inkonchain.com |
| Chain ID | 57073 |
| 货币符号 | ETH |
| 区块浏览器 | https://explorer.inkonchain.com |
### 步骤 3:获取 Gas 费用(ETH)
在 Ink 网络上进行任何操作都需要少量 ETH 作为 Gas 费用。
**获取方式:**
- **从 CEX 直接提现**:Kraken 支持零手续费提现到 Ink 网络
- **跨链桥接**:使用 [Superbridge](https://superbridge.app/)、[Bungee](https://bungee.exchange/) 或 [Relay](https://relay.link/) 从其他链桥接 ETH 到 Ink
> 建议至少准备 0.01-0.05 ETH 用于支付 Gas 费用
### 步骤 4:存入交易资金
1. 在 Nado 网站导航到 **Portfolio** 页面
2. 点击 **Deposit**
3. 选择要存入的资产(支持 USDT0、wETH、USDC、kBTC、wBTC
4. 输入金额并确认交易
---
## 获取 Nado 鉴权信息(重要)
这是配置机器人最关键的一步。Nado 使用基于 EVM 的签名认证方式,你需要获取以下两个关键信息:
- **NADO_SIGNER_PRIVATE_KEY**:签名私钥
- **NADO_SUBACCOUNT_OWNER**:子账户所有者地址
### 获取方式:从浏览器开发者工具提取
#### 步骤 1:登录 Nado 交易界面
1. 访问 https://app.nado.xyz
2. 连接你的钱包并完成登录
3. 确保你已经在 Nado 启用了一键交易功能并能正常下单
#### 步骤 2:打开浏览器开发者工具
- **Chrome / Edge**:按 `F12``Ctrl+Shift+I`Mac 上是 `Cmd+Option+I`
- **Firefox**:按 `F12``Ctrl+Shift+I`
- **Safari**:先在偏好设置中启用开发者菜单,然后按 `Cmd+Option+I`
#### 步骤 3:找到 Local Storage 中的私钥
1. 在开发者工具中,切换到 **Application** 标签(Chrome/Edge)或 **Storage** 标签(Firefox
2. 在左侧菜单找到 **Local Storage**
3. 点击展开,找到 `https://app.nado.xyz`
4. 在右侧列表中找到 **`nado.userSettings`** 这一项
5. 点击这一项,查看其 Value(值)
#### 步骤 4:提取私钥
`nado.userSettings` 的值是一个 JSON 对象,大致结构如下:
```json
"signingPreferenceBySubaccountKey": {
"inkMainnet_default": {
{
"privateKey": "0x1234567890abcdef...",
...
}
}
}
```
**你需要的是 `privateKey` 字段的值**,它是一个以 `0x` 开头的 64 位十六进制字符串。
将这个值复制下来,这就是你的 `NADO_SIGNER_PRIVATE_KEY`
#### 步骤 5:获取子账户所有者地址
`NADO_SUBACCOUNT_OWNER` 就是你连接到 Nado 的钱包地址。
获取方式:
1. 打开你的钱包(如 MetaMask)
2. 复制你的钱包地址(以 `0x` 开头的 42 位地址)
这就是你的 `NADO_SUBACCOUNT_OWNER`
### 关于 Linked Signer(进阶)
Nado 支持 "Linked Signer" 功能,允许你使用一个专门的签名密钥来代表你的主账户进行交易。这提供了额外的安全层:
- 主钱包私钥保持离线安全
- Linked Signer 只有交易权限,无法提取资金
- 可以随时撤销 Linked Signer
当你在 Nado 网站首次连接钱包时,系统会自动为你创建一个 Linked Signer,这个签名密钥就存储在浏览器的 Local Storage 中。
> **重要安全提示**
> - `NADO_SIGNER_PRIVATE_KEY` 是 Linked Signer 的私钥,不是你主钱包的私钥
> - 这个私钥只能用于在 Nado 上签署交易,无法直接转移你的链上资产
> - 但仍需妥善保管,不要分享给他人

## 配置 .env 文件
### 步骤 1:创建 .env 文件
在项目根目录下,复制示例配置文件:
```bash
cp .env.example .env
```
### 步骤 2:编辑 .env 文件
使用任意文本编辑器打开 `.env` 文件:
```bash
# macOS
open -e .env
# Linux
nano .env
# Windows
notepad .env
```
### 步骤 3:填写 Nado 配置
`.env` 文件中找到并修改以下配置项:
```bash
# ============================================
# 交易所选择
# ============================================
EXCHANGE=nado
# ============================================
# Nado 交易所配置(必填)
# ============================================
# 签名私钥 - 从浏览器 Local Storage 获取
# 格式:以 0x 开头的 64 位十六进制字符串
NADO_SIGNER_PRIVATE_KEY=0x你的私钥
# 子账户所有者地址 - 你的钱包地址
# 格式:以 0x 开头的 42 位地址
NADO_SUBACCOUNT_OWNER=0x你的钱包地址
# 子账户名称(可选,默认为 default)
NADO_SUBACCOUNT_NAME=default
# 网络环境(可选)
# inkMainnet = 主网(真实交易)
# inkTestnet = 测试网(模拟交易)
NADO_ENV=inkMainnet
# 交易品种(可选,默认 BTC-PERP)
NADO_SYMBOL=BTC-PERP
# ============================================
# 交易参数配置
# ============================================
# 单笔交易数量(以 BTC 计)
TRADE_AMOUNT=0.001
# 止损金额(USD)- 亏损超过此金额触发平仓
LOSS_LIMIT=10
# 移动止盈触发金额(USD
TRAILING_PROFIT=5
# 移动止盈回撤比例(0.2 = 20%)
TRAILING_CALLBACK_RATE=0.2
```
### 完整的 Nado 配置示例
```bash
# 交易所选择
EXCHANGE=nado
# Nado 凭证
NADO_SIGNER_PRIVATE_KEY=0x1234567890abcdef1234567890abcdef1234567890abcdef1234567890abcdef

# 趋势策略
LOSS_LIMIT=10
TRAILING_PROFIT=5
TRAILING_CALLBACK_RATE=0.2
# 波段策略
SWING_DIRECTION=short
SWING_STOP_LOSS_PCT=0.05 # 价格反向运动 5% 止损
# 做市策略参数(如果使用做市策略)
LOSS_LIMIT=0.08
MAKER_LOSS_LIMIT=0.08

```
## 启动交易机器人
### 方法一:交互式启动(推荐新手)
```bash
bun run index.ts
```
启动后会显示一个交互式菜单,使用方向键选择策略,按回车确认。
### 方法二:命令行直接启动
```bash
# 启动趋势策略
bun run index.ts --strategy trend --silent
# 启动做市策略
bun run index.ts --strategy maker --silent
```
### 方法三:使用 PM2 后台运行(推荐生产环境)
```bash
# 安装 PM2
bun add -d pm2
# 后台启动趋势策略
bunx pm2 start bun --name ritmex-trend --cwd . --restart-delay 5000 -- run index.ts --strategy trend --silent
# 查看运行状态
bunx pm2 list
# 查看日志
bunx pm2 logs ritmex-trend
# 停止运行
bunx pm2 stop ritmex-trend
```

## 策略说明与选择
### 趋势策略(Trend
**适用场景**:单边行情,趋势明显的市场
**工作原理**
- 使用 SMA30(30 周期简单移动平均线)判断趋势
- 价格突破均线时开仓
- 内置止损和移动止盈
**配置参数**
```bash
TRADE_AMOUNT=0.001 # 单笔交易量
LOSS_LIMIT=10 # 止损金额(USD
TRAILING_PROFIT=5 # 移动止盈触发金额
TRAILING_CALLBACK_RATE=0.2 # 回撤比例
```
### 做市策略(Maker
**适用场景**:震荡行情,低波动市场
**工作原理**
- 在买卖盘口双边挂单
- 赚取买卖价差
- 根据持仓自动调整挂单方向
**配置参数**
```bash
MAKER_BID_OFFSET=0 # 买单价格偏移
MAKER_ASK_OFFSET=0 # 卖单价格偏移
MAKER_REFRESH_INTERVAL_MS=500 # 刷新间隔
```
## 常见问题与排查
### 问题 1:启动时提示 "Missing NADO_SIGNER_PRIVATE_KEY"
**原因**:未正确配置签名私钥
**解决方案**
1. 确认 `.env` 文件存在于项目根目录
2. 检查 `NADO_SIGNER_PRIVATE_KEY` 是否正确填写
3. 确保私钥以 `0x` 开头
### 问题 2:启动时提示 "Missing NADO_SUBACCOUNT_OWNER"
**原因**:未配置子账户所有者地址
**解决方案**
1.`.env` 中填写 `NADO_SUBACCOUNT_OWNER` 为你的钱包地址
2. 也可以使用 `NADO_EVM_ADDRESS` 作为替代
### 问题 3:连接失败,无法获取账户信息
**可能原因及解决方案**
1. **网络问题**:检查网络连接,确保能访问 Nado API
2. **私钥错误**:重新从浏览器 Local Storage 获取正确的私钥
3. **账户未激活**:确保在 Nado 网站上至少存入过资金
4. **Linked Signer 未启用**:账户需要至少有 5 USDT 价值的资产才能使用 Linked Signer
### 问题 4:下单失败,提示精度错误
**原因**:价格或数量精度不符合交易所要求
**解决方案**
```bash
# BTC-PERP 的标准精度
PRICE_TICK=0.1 # 价格精度 0.1 USD
QTY_STEP=0.001 # 数量精度 0.001 BTC
```
### 问题 5:时间同步错误
**原因**:本地时间与服务器时间相差太大
**解决方案**
- macOS/Linux`sudo ntpdate -u time.apple.com`
- Windows:设置 → 时间和语言 → 同步时间
### 问题 6Gas 费用不足
**原因**Ink 网络上的 ETH 余额不足
**解决方案**
1. 通过跨链桥向 Ink 网络转入少量 ETH0.01-0.05 ETH
2. 推荐使用 Superbridge 或 Relay 进行跨链
### 问题 7:找不到 Local Storage 中的私钥
**可能原因**
1. 尚未在 Nado 完成首次连接/操作
2. 浏览器清除了缓存
**解决方案**
1. 重新访问 https://app.nado.xyz
2. 连接钱包并进行一次操作(如查看账户)
3. 再次检查 Local Storage
---
## 安全提示
1. **永远不要分享你的私钥**`NADO_SIGNER_PRIVATE_KEY` 虽然不是主钱包私钥,但仍可用于在 Nado 上进行交易
2. **使用专用交易账户**:建议创建一个专门用于交易的新钱包,不要放置大量资产
3. **定期检查授权**:在钱包中定期检查并撤销不需要的 DApp 授权
4. **小额测试**:首次运行时使用小额资金测试,确认一切正常后再增加资金
5. **保护 .env 文件**
- 不要将 `.env` 文件提交到 Git
- 不要分享给他人
- 定期更换凭证
