 ## Exchange Setup Guides
+
 ### Aster
 1. Keep `EXCHANGE=aster` (default value).
 2. Supply `ASTER_API_KEY` and `ASTER_API_SECRET`.
 3. Adjust `TRADE_SYMBOL`, `PRICE_TICK`, and `QTY_STEP` to match the requested market.
 4. The bootstrap script auto-populates these variables; manual installs must maintain them.

+### StandX
+
+* [StandX Maker Points Strategy Guide](docs/standx/maker-points-guide.md)
+
+The strategy requires a StandX API Token and signing private key to place orders.
+
+**How to obtain (using StandX's official API generation feature):**
+1. Open the StandX official API creation page: https://standx.com/user/session
+2. Connect your wallet and log in
+3. Click the **"Generate API Token"** button
+4. The page will display the following information:
+   - **Token** (JWT string starting with `eyJ`) → Fill in `STANDX_TOKEN`
+   - **Ed25519 Private Key** (Base58 format, like `HdsyJD7oWgT...`) → Fill in `STANDX_REQUEST_PRIVATE_KEY`
+   - **Creation date** and **Validity days** → Used to configure token expiry reminders
+
+> The Ed25519 Private Key is an auto-generated signing key used only for trade request signatures. Your assets remain in your main wallet and are completely safe.
+
+Please keep these credentials safe and do not share them with anyone.
+
+**Configuration steps:**
+1. Set `EXCHANGE=standx`.
+2. Provide `STANDX_TOKEN` (JWT token for perps API).
+3. Provide `STANDX_REQUEST_PRIVATE_KEY` (Ed25519 signing private key, Base58 format).
+4. Set `STANDX_SYMBOL` (defaults to `BTC-USD`) and align `PRICE_TICK` / `QTY_STEP`.
+5. Recommended: configure token expiry settings:
+   - `STANDX_TOKEN_CREATE_DATE` (creation date, format `YYYY-MM-DD`)
+   - `STANDX_TOKEN_VALIDITY_DAYS` (validity days)
+6. Optional: `STANDX_BASE_URL`, `STANDX_WS_URL`, or `STANDX_SESSION_ID` for custom endpoints.
+
 ### GRVT

 ### Lighter
 1. Set `EXCHANGE=lighter`.
-2. Provide `LIGHTER_ACCOUNT_INDEX` and `LIGHTER_API_PRIVATE_KEY` (40-byte hex private key).
+2. Provide `LIGHTER_ACCOUNT_INDEX` and `LIGHTER_API_PRIVATE_KEY` (40-byte hex private key). `LIGHTER_ACCOUNT_INDEX` is your account index, which you can find by opening DevTools (F12) on the official website and observing API requests. `LIGHTER_API_PRIVATE_KEY` is your API private key.
 3. Switch `LIGHTER_ENV` to `mainnet`, `staging`, or `dev` when necessary; override `LIGHTER_BASE_URL` if endpoints differ.
 4. `LIGHTER_SYMBOL` defaults to `BTCUSDT`; override price/size decimals when markets differ.

 ### Backpack
 1. Set `EXCHANGE=backpack`.
-2. Populate `BACKPACK_API_KEY`, `BACKPACK_API_SECRET`, and `BACKPACK_PASSWORD`; add `BACKPACK_SUBACCOUNT` if you trade from a subaccount.
+2. Populate `BACKPACK_API_KEY`, `BACKPACK_API_SECRET`, and `BACKPACK_PASSWORD`; add `BACKPACK_SUBACCOUNT` if you trade from a subaccount (defaults to main account ID).
 3. Toggle `BACKPACK_SANDBOX=true` for the sandbox environment and verify `BACKPACK_SYMBOL` matches the contract (defaults to `BTC_USD_PERP`).
 4. Enable `BACKPACK_DEBUG=true` for verbose adapter logging.

 ### Paradex
 1. Set `EXCHANGE=paradex`.
-2. Provide `PARADEX_PRIVATE_KEY` (EVM private key) and `PARADEX_WALLET_ADDRESS`.
+2. Provide `PARADEX_PRIVATE_KEY` (EVM private key) and `PARADEX_WALLET_ADDRESS`. Note: These are your EVM wallet address and private key. It is recommended to create a brand new wallet and avoid storing unrelated assets in it.
 3. The adapter connects to mainnet by default; enable `PARADEX_SANDBOX=true` and adjust `PARADEX_SYMBOL` for testnet usage.
 4. Advanced tuning: use `PARADEX_USE_PRO`, `PARADEX_RECONNECT_DELAY_MS`, or debug flags as needed.

+### Nado
+1. Set `EXCHANGE=nado`.
+2. On the Nado web app (trading interface), open DevTools (F12) -> switch to the `Application` tab -> `Local Storage`, locate `nado.userSettings`, then grab the `privateKey` field from its JSON value and paste it into `.env` as `NADO_SIGNER_PRIVATE_KEY`.
+3. Provide `NADO_SUBACCOUNT_OWNER` (or `NADO_EVM_ADDRESS`).
+4. Select network via `NADO_ENV=inkMainnet` (mainnet) or `inkTestnet` (testnet).
+5. Set `NADO_SYMBOL` using Nado product symbols like `BTC-PERP` (it also accepts `BTCUSDT0` and maps it to `BTC-PERP`).

+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.

+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-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

+
+## 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())
+```
+

+
+## 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.
+
+## Testing
+
+The SDK includes comprehensive test coverage with multiple test suites:
+
+### Unit Tests
+```bash
+# Run unit tests (no API credentials required)
+python -m pytest tests/test_client.py tests/test_starkex_signing_adapter.py -v
+```
+
+### Public API Tests

+
+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

+# API
+
+## Overview
+
+Nado's API is divided into the following categories:
+
+1. A **websocket/REST** API (**gateway**) that supports writes (executes) and polling (queries).
+2. A **subscriptions** API that allows to subscribe to live data feeds.
+3. An **indexer** API (**archive**) that allows you to query historical data.
+4. A **trigger** API that allows to execute orders only under specified price conditions.
+
+{% hint style="info" %} <mark style="color:purple;">**NOTE**</mark>: To contact the Nado team with any questions or inquiries about Private Gateway connections, such as increased limits, please reach out on the Telegram channel below:

+# API Changelog
+
+This document tracks all changes to the Nado API.
+
+***
+
+<details>
+
+<summary><strong>December 11, 2025</strong></summary>
+
+**Risk System Updates**
+
+**Spread Weight Caps**
+
+* Introduced upper bounds for spread weights to manage risk at extreme leverage levels:
+  * <mark style="color:red;">`initial_spread_weight`</mark>: Maximum **0.99**
+  * <mark style="color:red;">`maintenance_spread_weight`</mark>: Maximum **0.994**
+* **Impact**:
+  * Existing markets (≤20x leverage): No change in behavior
+  * Future high-leverage markets (30x+): Spread positions will have capped health benefits
+  * Prevents extreme leverage abuse via spread positions
+* **Technical Details**:
+  * Base spread weight calculated as: `spread_weight = 1 - (1 - product_weight) / 5`
+  * Final spread weight: `min(spread_weight, cap)`
+  * Cap applies during health calculations for spread positions
+
+**Minimum Liquidation Penalties**
+
+* Introduced minimum distance requirements between oracle price and liquidation price:
+  * <mark style="color:red;">**Non-spread liquidations**</mark>: Minimum **0.5%** from oracle price
+  * <mark style="color:red;">**Spread liquidations**</mark>: Minimum **0.25%** from oracle price
+* **Impact**:
+  * Ensures liquidators always have sufficient incentive to execute liquidations
+  * Prevents unprofitable liquidation scenarios for low-volatility assets
+  * Particularly important for high-leverage positions where natural penalties may be very small
+* **Technical Details**:
+  * **Non-spread longs**: `oracle_price × (1 - max((1 - maint_asset_weight) / 5, 0.005))`
+  * **Non-spread shorts**: `oracle_price × (1 + max((maint_liability_weight - 1) / 5, 0.005))`
+  * **Spread selling**: `spot_price × (1 - max((1 - perp_maint_asset_weight) / 10, 0.0025))`
+  * **Spread buying**: `spot_price × (1 + max((spot_maint_liability_weight - 1) / 10, 0.0025))`
+
+**API Response Changes**
+
+* No breaking changes to API response structure
+* Health calculations and liquidation prices automatically reflect new risk parameters
+
+**Documentation Updates**
+
+* See [Subaccounts & Health](https://docs.nado.xyz/subaccounts-and-health#spreads) for spread weight cap details
+* See [Liquidations](https://docs.nado.xyz/liquidations#liquidation-price) for minimum liquidation penalty details

+
+<summary><strong>December 1, 2025</strong></summary>
+
+**Query Enhancements**
+
+**Pre-State Simulation for SubaccountInfo Query**
+
+* Added <mark style="color:red;">`pre_state`</mark> parameter to <mark style="color:red;">`SubaccountInfo`</mark> query
+  * Type: <mark style="color:red;">`string`</mark> (accepts <mark style="color:red;">`"true"`</mark> or <mark style="color:red;">`"false"`</mark>)
+  * When set to <mark style="color:red;">`"true"`</mark> along with <mark style="color:red;">`txns`</mark>, returns a <mark style="color:red;">`pre_state`</mark> object in the response
+  * <mark style="color:red;">`pre_state`</mark> contains the subaccount state **before** the simulated transactions were applied
+  * Useful for comparing before/after states when simulating trades
+  * <mark style="color:red;">`pre_state`</mark> includes:
+    * <mark style="color:red;">`healths`</mark>: Health information before transactions
+    * <mark style="color:red;">`health_contributions`</mark>: Per-product health contributions before transactions
+    * <mark style="color:red;">`spot_balances`</mark>: Spot balances before transactions
+    * <mark style="color:red;">`perp_balances`</mark>: Perpetual balances before transactions
+
+**Use Cases:**
+
+* Position simulation and preview
+* Risk analysis for potential trades
+* UI/UX for showing before/after comparisons
+* Testing transaction impacts without on-chain execution
+
+**Documentation:** See [Subaccount Info Query](https://docs.nado.xyz/developer-resources/gateway/queries/subaccount-info#example-with-pre_state) for detailed examples.

+<details>
+
+<summary><strong>November 20, 2025 - Initial Launch</strong></summary>
+
+#### Core Changes
+
+**1. Removal of LP Functionality**
+
+* <mark style="color:red;">`SubaccountInfo`</mark> no longer has:
+  * <mark style="color:red;">`lp_balance`</mark> in <mark style="color:red;">`spot_balances`</mark> and <mark style="color:red;">`perp_balances`</mark>
+  * <mark style="color:red;">`lp_state`</mark> in <mark style="color:red;">`spot_products`</mark> and <mark style="color:red;">`perp_products`</mark>
+  * <mark style="color:red;">`lp_spread_x18`</mark> in <mark style="color:red;">`book_info`</mark> of both <mark style="color:red;">`spot_products`</mark> and <mark style="color:red;">`perp_products`</mark>
+* Historical <mark style="color:red;">`events`</mark> no longer include:
+  * <mark style="color:red;">`net_entry_lp_unrealized`</mark>
+  * <mark style="color:red;">`net_entry_lp_cumulative`</mark>
+
+**2. Removal of Redundant Fields**
+
+* <mark style="color:red;">`SubaccountInfo`</mark> no longer has:
+  * <mark style="color:red;">`last_cumulative_multiplier_x18`</mark> in <mark style="color:red;">`balance`</mark> of <mark style="color:red;">`spot_balances`</mark>
+
+**3. Products Config Model Updates**
+
+* Added: <mark style="color:red;">`withdraw_fee_x18`</mark> and <mark style="color:red;">`min_deposit_rate_x18`</mark> to <mark style="color:red;">`spot_products.config`</mark>
+
+**4. Products Risk Model Updates**
+
+* Added: <mark style="color:red;">`price_x18`</mark> to both <mark style="color:red;">`spot_products.risk`</mark> and <mark style="color:red;">`perp_products.risk`</mark>
+* Removed: <mark style="color:red;">`large_position_penalty_x18`</mark>
+
+**5. Deposit Rate Query**
+
+* Removed: <mark style="color:red;">`min_deposit_rates`</mark> query
+* Use <mark style="color:red;">`min_deposit_rate_x18`</mark> in <mark style="color:red;">`spot_products.config`</mark> instead
+
+#### Market Structure Changes
+
+**6. Removal of Virtual Books**
+
+* <mark style="color:red;">`Contracts`</mark> query no longer returns <mark style="color:red;">`book_addrs`</mark>
+* <mark style="color:red;">`PlaceOrder`</mark> verify contract is now <mark style="color:red;">`address(product_id)`</mark>\
+  \&#xNAN;*Example: product <mark style="color:red;">18</mark> → <mark style="color:red;">`0x0000000000000000000000000000000000000012`</mark>*
+
+**7. Minimum Size denomination**
+
+* <mark style="color:red;">`min_size`</mark> is now **USDT0 denominated** (not base denominated)
+  * <mark style="color:red;">`min_size = 10`</mark> → minimum order size = 10 USDT0 (<mark style="color:red;">`order_price * order_amount`</mark>)
+* <mark style="color:red;">`size_increment`</mark> remains **base denominated**
+  * Example: BTC with <mark style="color:red;">`size_increment = 0.0001`</mark> and <mark style="color:red;">`min_size = 20`</mark>:
+    * ✅ Valid: 100,000 \* 0.0002 = 20 USDT0
+    * ❌ Invalid: 100,000 \* 0.0001 = 10 USDT0
+    * ❌ Invalid: 100,000 \* 0.00025 (not multiple of 0.0001)
+
+#### Orders & Signing
+
+**8. Place Orders Execute**
+
+* Added: <mark style="color:red;">`place_orders`</mark> execute - place multiple orders in a single request
+  * Accepts array of orders with same structure as <mark style="color:red;">`place_order`</mark>
+  * Optional <mark style="color:red;">`stop_on_failure`</mark> parameter to stop processing remaining orders on first failure
+  * Returns array of results with <mark style="color:red;">`digest`</mark> (if successful) or <mark style="color:red;">`error`</mark> (if failed) for each order
+  * Rate limit weight calculated per order
+
+See [Place Orders](https://docs.nado.xyz/developer-resources/api/gateway/executes/place-orders) for details.
+
+**9. EIP712 `Order` Struct Update**
+
+```solidity
+struct Order {
+    bytes32 sender;
+    int128 priceX18;
+    int128 amount;
+    uint64 expiration;
+    uint64 nonce;
+    uint128 appendix;
+}
+```
+
+* New field: <mark style="color:red;">`appendix`</mark>
+* All order flags (IOC, post only, reduce-only, triggers) moved into <mark style="color:red;">`appendix`</mark>
+* <mark style="color:red;">`expiration`</mark> is now strictly a timestamp
+* <mark style="color:red;">`appendix`</mark> bitfield:
+
+```json
+| value   | reserved | trigger | reduce only | order type | isolated | version |
+| 64 bits | 50 bits  | 2 bits  | 1 bit       | 2 bits     | 1 bit    | 8 bits  |
+```
+
+* Special encodings:
+  * <mark style="color:red;">`trigger`</mark> = 2 or 3 → <mark style="color:red;">`value`</mark> encodes TWAP settings (<mark style="color:red;">`times`</mark>, <mark style="color:red;">`slippage_x6`</mark>)
+  * <mark style="color:red;">`isolated = 1`</mark> → <mark style="color:red;">`value`</mark> encodes isolated margin
+* Constraints:
+  * Isolated orders cannot be TWAP
+  * TWAP orders must use IOC execution type
+
+See [Order Appendix Docs](https://docs.nado.xyz/developer-resources/api/order-appendix).
+
+**10. TWAP Order Execution**
+
+* Added <mark style="color:red;">`list_twap_executions`</mark> query to trigger service
+* TWAP orders track individual execution status (pending, executed, failed, cancelled)
+* TWAP execution statuses include execution time and engine response data
+
+**11. Trigger Service Rate Limits**
+
+* Updated trigger order limits from 100 pending orders per subaccount to <mark style="color:red;">`25 pending orders per product per subaccount`</mark>
+
+**12. EIP712 Domain Change**
+
+* Signing domain updated from **`Vertex` → `Nado`**\
+  See [Signing Docs](https://docs.nado.xyz/developer-resources/api/gateway/signing).

+
+### **Unsettled USDT0**
+
+Perp balances have two main components:
+
+* <mark style="color:red;">`amount`</mark>
+* <mark style="color:red;">`v_quote_balance`</mark>
+
+When you buy a perp, <mark style="color:red;">`amount`</mark> increments and <mark style="color:red;">`v_quote_balance`</mark> decrements, and vice versa for selling.
+
+Settlement is the process of converting from <mark style="color:red;">v\_quote\_balance</mark> into actual USDT0 balance. This happens mostly on position close, but may happen on extremely negative PNL positions when we need to pay out positive PNL positions.
+
+The amount that is transferred between <mark style="color:red;">`v_quote_balance`</mark> in the perp and your USDT0 balance is an amount that results in <mark style="color:red;">`amount * oracle_price + v_quote_balance == 0`</mark>. Unsettled USDT0 is the total amount that would be transferred between <mark style="color:red;">`v_quote_balance`</mark> and your USDT0 balance summed across all perps.
+
+### **Unsettled PNL**
+
+**Note:** Technically, there is no such concept as "Unsettled PNL" in our system. However, the UI displays "Unsettled PnL" in some places (e.g., in the USDT0 Balance section) for user clarity.
+
+**What the UI actually shows:** When you see "Unsettled PnL" in the UI, it refers to **Unsettled USDT0** (see above) - the total unsettled quote balance across all perp positions.
+
+**For developers:** Always use **Unsettled USDT0** when referring to this value programmatically. It represents the sum of <mark style="color:red;">`amount × oracle_price + v_quote_balance`</mark> across all perp positions, which is the amount that would be settled into your USDT0 balance.
+
+### **Unrealized PNL**
+
+Refers to the estimated gains or losses of a current position based on the difference between the average entry price and the current oracle price.
+
+## Formulas
+
+### **Unrealized PNL**
+
+Using the [indexer's events query](https://docs.nado.xyz/developer-resources/api/archive-indexer/events), your unrealized PNL at the end of some event is given by:
+
+{% code lineNumbers="true" %}
+
+```python
+unrealized_pnl = (
+    event.post_balance.amount * event.product.oracle_price_x18 
+    - event.net_entry_unrealized
+)
+```
+
+{% endcode %}
+
+### Total PNL
+
+Your total PNL between <mark style="color:red;">`event1`</mark> and <mark style="color:red;">`event2`</mark>, assuming <mark style="color:red;">`event1`</mark> is after <mark style="color:red;">`event2`</mark> - is given by:
+
+<pre class="language-python" data-line-numbers><code class="lang-python"><strong>total_pnl = (
+</strong><strong>    (event1.post_balance.amount * event1.product.oracle_price_x18 - event1.net_entry_cumulative)
+</strong><strong>    - (event2.post_balance.amount * event2.product.oracle_price_x18 - event2.net_entry_cumulative)
+</strong><strong>)
+</strong></code></pre>
+
+{% hint style="info" %}
+**Notes**:
+
+* You can use 0 for the second term for the PNL to compute since the beginning of time.
+* For spots, we will count deposits and withdraws towards your PNL. i.e. if you deposit BTC, for PNL tracking purposes it is counted as a BTC long at the oracle price.

+# Depositing
+
+There are two ways to deposit funds into Nado:
+
+1. **Direct Deposit** - Simple transfer to your unique deposit address (recommended for most users)
+2. **On-Chain Contract Call** - Direct interaction with the Endpoint contract
+
+***
+
+## Method 1: Direct Deposit (Recommended)
+
+Each subaccount has a unique deposit address. Simply send funds to this address and they will automatically be credited to your subaccount.
+
+### Getting Your Deposit Address
+
+Query your unique deposit address using the [Direct Deposit Address](https://docs.nado.xyz/developer-resources/api/archive-indexer/direct-deposit-address) endpoint:
+
+**Request:**
+
+```json
+{
+  "direct_deposit_address": {
+    "subaccount": "0x79cc76364b5fb263a25bd52930e3d9788fcfeea864656661756c740000000000"
+  }
+}
+```
+
+**Response:**
+
+```json
+{
+  "subaccount": "0x79cc76364b5fb263a25bd52930e3d9788fcfeea864656661756c740000000000",
+  "deposit_address": "0x1234567890123456789012345678901234567890",
+  "created_at": "1683315718"
+}
+```
+
+### Depositing Funds
+
+1. Get your deposit address using the API call above
+2. Send the supported token to this address (e.g., USDT0, wETH, etc.)
+3. Funds will be automatically credited to your subaccount within a few seconds
+
+**Advantages:**
+
+* No need to interact with smart contracts
+* No need to approve allowances
+* Works with any wallet (including CEX withdrawals)
+* Simpler integration for users
+
+**Notes:**
+
+* Only send supported tokens to this address
+* Find supported tokens via the [All Products](https://docs.nado.xyz/developer-resources/api/gateway/queries/all-products) query
+* Deposits are processed automatically after blockchain confirmation
+
+***
+
+## Method 2: On-Chain Contract Call
+
+Advanced users can deposit directly by calling the Endpoint contract.
+
+### Contract Address
+
+Find the Endpoint contract address at:
+
+```
+GET <nado-url>/query?type=contracts
+```
+
+### Function Interface
+
+#### Basic Deposit
+
+```solidity
+function depositCollateral(
+    bytes12 subaccountName,  // last 12 bytes of the subaccount bytes32
+    uint32 productId,        // product ID for the token
+    uint128 amount          // raw token amount (see decimals below)
+) external
+```
+
+**Parameters:**
+
+* `subaccountName`: The last 12 bytes of your subaccount identifier (e.g., `0x64656661756c740000000000` for "default")
+* `productId`: The product ID for the token you're depositing
+* `amount`: The raw amount in the token's smallest unit
+  * For USDT0 (6 decimals): 1 USDT0 = `1e6` = `1000000`
+  * For wETH (18 decimals): 1 wETH = `1e18`
+  * For wBTC (8 decimals): 1 wBTC = `1e8`
+
+#### Deposit with Referral Code
+
+```solidity
+function depositCollateralWithReferral(
+    bytes32 subaccount,      // full 32-byte subaccount identifier
+    uint32 productId,        // product ID for the token
+    uint128 amount,         // raw token amount
+    string memory referralCode  // referral code (optional)
+) public
+```
+
+### Prerequisites
+
+Before depositing via contract call, you must:
+
+1. **Approve Token Allowance**
+
+   ```solidity
+   // Give the Endpoint contract permission to transfer your tokens
+   IERC20(tokenAddress).approve(endpointAddress, amount);
+   ```
+2. **Get Product Information**
+   * Use [All Products](https://docs.nado.xyz/developer-resources/api/gateway/queries/all-products) query to find:
+     * Product ID for your token
+     * Token contract address
+     * Token decimals
+
+### Example: Depositing 100 USDT0
+
+Assuming USDT0 has product ID `0` and 6 decimals:
+
+```typescript
+// 1. Approve allowance (one-time or as needed)
+await usdtContract.approve(endpointAddress, ethers.constants.MaxUint256);
+
+// 2. Deposit 100 USDT0
+const subaccountName = ethers.utils.formatBytes32String("default").slice(0, 26); // bytes12
+const productId = 0;
+const amount = 100 * 1e6; // 100 USDT0 with 6 decimals
+
+await endpointContract.depositCollateral(subaccountName, productId, amount);
+```
+
+### Processing Time
+
+Deposits may take a few seconds to process after transaction confirmation. You can monitor your balance via:
+
+* [Subaccount Info](https://docs.nado.xyz/developer-resources/api/gateway/queries/subaccount-info) query
+* WebSocket subscriptions for real-time updates
+
+***
+
+## Important Notes
+
+* **Use Correct Product ID**: Each token has a specific product ID. Using the wrong ID will cause the transaction to fail.
+* **Check Token Decimals**: Always multiply by the correct decimal factor (6 for USDT0, 18 for wETH, etc.)
+* **Minimum Deposit**: Some products may have minimum deposit amounts
+* **Only Supported Tokens**: Only deposit tokens that are listed via the All Products query
+
+***
+
+## Getting Token Information
+
+Use the [All Products](https://docs.nado.xyz/developer-resources/api/gateway/queries/all-products) query to get:
+
+```json
+{
+  "product_id": 0,
+  "symbol": "USDT0",
+  "token": "0x...",  // token contract address
+  "decimals": 6
+}
+```
+
+This information is essential for:
+
+* Finding the correct `productId`
+* Getting the token contract for approvals (Method 2 only)
+* Calculating the correct `amount` with proper decimals

+# Executes
+
+## Overview
+
+All executes go through the following endpoint; the exact details of the execution are specified by the JSON payload.
+
+* **Websocket**: <mark style="color:orange;">`WEBSOCKET [GATEWAY_WEBSOCKET_ENDPOINT]`</mark>
+* **REST**: <mark style="color:orange;">`POST [GATEWAY_REST_ENDPOINT]/execute`</mark>
+
+### **Signing**
+
+All executes are signed using [EIP712](https://eips.ethereum.org/EIPS/eip-712). Each execute request contains:
+
+1. A piece of structured data that includes the sender address
+2. A signature of the hash of that structured data, signed by the sender
+
+You can check the SDK for some examples of how to generate these signatures.
+
+{% hint style="info" %}
+See more info in the [signing](https://docs.nado.xyz/developer-resources/api/gateway/signing) page.
+{% endhint %}
+
+### **Sender Field Structure**
+
+The sender field is a solidity <mark style="color:red;">`bytes32`</mark> . There are two components:
+
+* an <mark style="color:red;">`address`</mark> that is a <mark style="color:red;">`bytes20`</mark>
+* a subaccount identifier that is a <mark style="color:red;">`bytes12`</mark>
+
+For example, if your address was <mark style="color:red;">`0x7a5ec2748e9065794491a8d29dcf3f9edb8d7c43`</mark>, and you wanted to use the default subaccount identifier (i.e: the word <mark style="color:red;">`default`</mark>) you can set <mark style="color:red;">`sender`</mark> to <mark style="color:red;">`0x7a5ec2748e9065794491a8d29dcf3f9edb8d7c4364656661756c740000000000`</mark> , which sets the subaccount identifier to <mark style="color:red;">`64656661756c740000000000`</mark>.
+
+### **Amounts**
+
+For <mark style="color:red;">`DepositCollateral`</mark> and <mark style="color:red;">`WithdrawCollateral`</mark>, the amount specifies the physical token amount that you want to receive. `i.e.` if USDT0 has 6 decimals, and you want to deposit or withdraw 1 USDT0, you specify <mark style="color:red;">`amount = 1e6`</mark>.
+
+For all other transactions, amount is normalized to 18 decimals, so <mark style="color:red;">`1e18`</mark> == one unit of the underlying asset. For example, if you want to buy 1 wETH, regardless of the amount of decimals the wETH contract has on chain, you specify <mark style="color:red;">`1e18`</mark> in the amount field of the order.
+
+## API Response

+
+<mark style="color:red;">`digests`</mark>: a list of order digests, represented as hex strings, for the orders you want to cancel.
+
+<mark style="color:red;">`nonce`</mark>: used to differentiate between the same cancellation multiple times, and a user trying to place a cancellation with the same parameters twice. Sent as a string. Encodes two bit of information:
+
+* Most significant <mark style="color:red;">`44`</mark> bits encoding the <mark style="color:red;">`recv_time`</mark> in milliseconds after which the cancellation should be ignored by the matching engine; the engine will accept cancellations where <mark style="color:red;">`current_time < recv_time <= current_time + 100000`</mark>
+* Least significant <mark style="color:red;">`20`</mark> bits are a random integer used to avoid hash collisions

+
+<mark style="color:red;">`priceX18`</mark>: an <mark style="color:red;">`int128`</mark> representing the price of the order multiplied by 1e18, sent as a string. For example, a price of 1 USDT0 would be sent as <mark style="color:red;">`"1000000000000000000"`</mark>
+
+<mark style="color:red;">`amount`</mark>: an <mark style="color:red;">`int128`</mark> representing the quantity of the order multiplied by 1e18, sent as a string. A positive amount means that this is a buy order, and a negative amount means this is a sell order.
+
+<mark style="color:red;">`expiration`</mark>: a time after which the order should automatically be cancelled, as a timestamp in seconds after the unix epoch, sent as a string.

+### Order Nonce

+* Least significant <mark style="color:red;">`20`</mark> bits are a random integer used to avoid hash collisions
+
+  For example, to place an order with a random integer of <mark style="color:red;">`1000`</mark>, and a discard time 50 ms from now, we would send a nonce of <mark style="color:red;">`((timestamp_ms() + 50) << 20) + 1000)`</mark>

+
+## Behavior
+
+* **Partial Success**: By default, orders are processed independently. Some orders may succeed while others fail.
+* **Stop on Failure**: Set `stop_on_failure: true` to stop processing remaining orders when the first order fails. Already successfully placed orders remain on the book.
+* **Order Signing**: Each order must be individually signed using EIP712 (see [Signing](https://docs.nado.xyz/developer-resources/api/gateway/signing) for details).
+* **Rate Limits**: Rate limit weight is calculated per order (1 per order with leverage, 20 per order without).
+
+## Use Cases
+
+* **Spread Trading**: Place both legs of a spread trade in one request
+* **Multiple Markets**: Open positions across multiple products in one request
+
+## Example
+

+# Transfer Quote
+
+## Fees
+
+Transfers between subaccounts incur a network fee:
+
+* **Standard transfers**: 1 USDT0
+* **Isolated subaccount transfers**: 0.1 USDT0 (when either sender or recipient is an isolated subaccount)
+
+The fee is automatically deducted from the sender's balance.
+
+## Rate limits
+
+* 60 transfer quotes/min or 10 every 10 seconds per wallet. (**weight=10**)
+* A max of 5 transfer quotes to new recipients (subaccounts) every 24hrs.
+  * **Note**: Transferring quote to a subaccount that doesn't exist, creates the subaccount.

+## Signing
+
+{% hint style="info" %}
+See more details and examples in our [signing](https://docs.nado.xyz/developer-resources/api/gateway/signing) page.
+{% endhint %}
+
+The solidity typed data struct that needs to be signed is:
+
+```solidity
+struct WithdrawCollateral {
+    bytes32 sender;
+    uint32 productId;
+    uint128 amount;
+    uint64 nonce;
+}
+```
+
+<mark style="color:red;">`sender`</mark>: a <mark style="color:red;">`bytes32`</mark> sent as a hex string; includes the address and the subaccount identifier.
+
+<mark style="color:red;">`productId`</mark>: a <mark style="color:red;">`uint32`</mark> that specifies the product you’d like to withdraw collateral from; must be for a spot product.
+
+<mark style="color:red;">`amount`</mark>: the amount of asset to withdraw, sent as a string. Note that this is different from the amounts provided in transactions that aren’t <mark style="color:red;">`depositCollateral`</mark>. This is the raw amount of the ERC20 token you want to receive, i.e. if USDT0 has 6 decimals and you want to withdraw 1 USDT0, specify 1e6; if wETH has 18 decimals and you want to withdraw 1 wETH, specify 1e18. Use [all products](https://docs.nado.xyz/developer-resources/api/gateway/queries/all-products) query to view the token address of the corresponding product which can be used to determine the correct decimals to use.
+
+<mark style="color:red;">`nonce`</mark>: the <mark style="color:red;">`tx_nonce`</mark>. This is an incrementing nonce, can be obtained using the [Nonces](https://docs.nado.xyz/developer-resources/api/gateway/queries/nonces) query.
+
+{% hint style="warning" %}
+**Note**: for signing you should always use the data type specified in the solidity struct which might be different from the type sent in the request e.g: <mark style="color:red;">`nonce`</mark> should be an <mark style="color:red;">`uint64`</mark> for **Signing** but should be sent as a <mark style="color:red;">`string`</mark> in the final payload.

+# Queries
+
+All queries go through the following endpoint; the exact details of the query are specified by query params or `Websocket` messages.
+
+* **Websocket**: <mark style="color:orange;">`WEBSOCKET [GATEWAY_WEBSOCKET_ENDPOINT]`</mark>
+* **REST**: <mark style="color:green;">`GET [GATEWAY_REST_ENDPOINT]/query`</mark> or <mark style="color:orange;">`POST [GATEWAY_REST_ENDPOINT]/query`</mark>
+
+## Overview
+
+### **Amounts and Prices**
+
+In general, amounts come back normalized to 18 decimal places. Meaning that for a balance of 1 USDT0, regardless of the number of decimals USDT0 has on-chain, a value of 1e18 will be returned.
+
+Prices are in <mark style="color:red;">`x18`</mark>, so if the price of one wBTC is $20,000, regardless of the number of decimals wBTC has on-chain, the price will be returned as <mark style="color:red;">`20,000 * 1e18`</mark>.
+
+## API Response
+
+All `queries` return in the format:
