# Frequently Asked Questions
#### 1. What are bStocks?
bStocks are tokenized securities that provide economic exposure to publicly traded stocks or ETFs through blockchain-based tokens. They allow users to trade stock-linked assets on Aster while maintaining exposure to the performance of the underlying security.
#### 2. Do I own the actual shares when I buy bStocks?
No. Holding a bStock does not make you a shareholder of the underlying company.
bStocks provide synthetic economic exposure and do not grant shareholder rights such as voting rights, direct dividend payments, shareholder communications, or participation in corporate governance.
#### 3. Can I convert between bStocks and the underlying security?
Yes. Eligible users may convert supported securities into the corresponding bStocks and convert supported bStocks back into the underlying securities, subject to product availability and applicable requirements.
#### 4. Can I trade bStocks at any time?
Yes.
bStocks are available for trading 24 hours a day, 7 days a week, including weekends and public holidays.
#### 5. Why doesn't the bStock price always match the underlying stock price?
Although bStocks reference publicly traded securities, their market price is determined by supply and demand on Aster.
Differences may occur due to:
* Market liquidity
* Bid-ask spreads
* Trading outside traditional market hours
* Market volatility
* Corporate action processing
* Other market conditions
As a result, bStocks may temporarily trade at a premium or discount to the underlying security.
#### 6. How are dividends handled?
Eligible cash dividends are automatically reinvested through the Multiplier mechanism.
Instead of receiving a separate cash payment, the economic value of the dividend is reflected by increasing your displayed bStock balance after the dividend has been processed.
No manual claim is required.
#### 7. What is the Ex-Dividend Date?
The Ex-Dividend Date determines eligibility for a dividend.
To receive the dividend for a particular distribution, you must hold the corresponding bStock before the Ex-Dividend Date.
Purchases made on or after the Ex-Dividend Date are not eligible for that dividend.
#### 8. What is the Record Date?
The Record Date is the date used to determine which holders are eligible for dividend processing.
Following the Record Date, eligible dividends are processed and reflected through an update to the Multiplier.
#### 9. What is the Multiplier?
The Multiplier is an adjustment factor used to reflect supported corporate actions without changing your raw on-chain token balance.
It is used for events including:
* Dividend reinvestments
* Stock splits
* Reverse stock splits
* Mergers
* Spin-offs
* Rights offerings
* ETF distributions
* Other supported corporate actions
#### 10. Why is my displayed balance different from my wallet balance?
Your wallet records the raw number of bStock tokens you own, while Aster displays the effective balance after applying the current Multiplier.
This difference is expected and allows corporate actions to be reflected without transferring additional tokens.
#### 11. Why didn't I receive additional tokens after a dividend?
Dividend reinvestments are processed through the Multiplier rather than by issuing new tokens.
Your raw on-chain balance remains unchanged, while your displayed balance increases automatically after dividend processing.
#### 12. What happens during a stock split?
When the underlying company performs a stock split, Aster updates the Multiplier to reflect the new share ratio.
Your displayed balance increases proportionally, while the market price per bStock adjusts accordingly.
The overall economic value of your holdings remains substantially unchanged, excluding normal market price movements.
#### 13. What happens during a reverse stock split?
A reverse stock split reduces the displayed number of shares while proportionally increasing the price per share.
Aster processes reverse splits through the Multiplier, preserving the intended economic exposure of your holdings.
#### 14. What other corporate actions are supported?
Aster may support processing for a variety of corporate actions, including:
* Cash dividends
* Stock splits
* Reverse stock splits
* Mergers and acquisitions
* Spin-offs
* Rights offerings
* ETF distributions
* Delistings
* Liquidations
* Other supported corporate events
Processing methods depend on the specific event.
#### 15. Will trading be interrupted during corporate actions?
Certain services may be temporarily paused while corporate actions are being processed.
Depending on the event, this may affect:
* Trading
* Deposits
* Withdrawals
* Conversions
Affected services will resume once processing has been completed.
#### 16. Are bStocks backed by underlying securities?
Each bStock is intended to be backed by corresponding underlying securities or other eligible assets held through the applicable custody arrangements, subject to the product's operational framework.
#### 17. Are bStocks suitable for long-term investing?
bStocks provide long-term economic exposure to publicly traded companies while automatically reflecting supported corporate actions such as dividend reinvestments and stock splits.
However, like any financial product, their value may rise or fall, and users should carefully evaluate the risks before investing.
#### 18. What risks should I understand before trading bStocks?
Before trading bStocks, you should understand that:
* bStocks are not direct ownership of company shares.
* Prices may differ from the underlying security.
* Corporate actions may temporarily affect trading and other services.
* Market liquidity and volatility may impact execution prices.
* The value of your investment may increase or decrease over time.

# Sub Accounts
### **Overview**
Sub-accounts allow you to run multiple independent trading strategies under a single master account. Each sub-account maintains its **own positions, assets, and API keys**, enabling effective risk isolation across different strategies.

| --------------------- | ------------------------------ |
| VIP level requirement | All VIP levels |
| Maximum sub-accounts | 10 to 50, varying by VIP level |

### **2. Creating a Sub-Account**
#### **How to**
1. Connect your **master account wallet** on Aster Web.
2. Click your wallet address (top-right) → **Sub-account management** → **Create Sub-account.**
3. Enter the sub-account name and configure trade settings (asset mode, position mode, etc.)
4. Save your private key immediately. The system generates a wallet address and private key (EVM or Solana, matching your master account type). This key is shown only once and is never stored by Aster.
5. Click Confirm and save, then confirm again in the second prompt. After closing the dialog, the key CANNOT be recovered.
Each sub-account creation requires a **wallet signature from the master account**.
Reminder: Aster never stores your private key. If you lose it, you cannot independently log in to or manage that sub-account. Save it to a secure location before dismissing the dialog.
#### **Naming Rules**
* 6 to 20 characters
* Must include at least one letter
* Numbers are allowed
* Special characters are not supported
### **3. Account Switching**
After creating sub-accounts, a dropdown menu will appear in the wallet panel.
* First switch requires a wallet signature
* Subsequent switches do not require re-signing (unless session is reset)
Important:
* Switching is only available when logged in as the master account
* When logged in directly as a sub-account, switching to other accounts is not supported
### **4. Fund Management**
Sub-accounts support deposits and internal transfers, but not direct withdrawals.
#### **Deposits**
Sub-accounts support the same onchain deposit methods as the master account.
* The system will remind you to confirm that you have saved your private key
* Solana deposits directly to sub-accounts are not supported (Use internal transfers as an alternative for Solana)
#### **Internal Transfers**
Internal transfers between master and sub-accounts are:
* Instant
* No fees

# Leverage
### **What is Leverage?**
Leverage enables you to control a larger position size than your actual wallet balance. For instance, with 5× leverage, a $1,000 margin allows you to open a $5,000 position. While this can magnify profits, it also increases potential losses.
### **Adjusting Your Leverage**
<figure><img src="https://4068247257-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FWhSHuKmgnGREbVb12PK2%2Fuploads%2FwOddeDaavsGMgf4iTye1%2Fimage.png?alt=media&token=eac6c664-5ed9-451d-92f4-c26a395be65a" alt="" width="563"><figcaption><p>BTC/USD's max leverage is 1,001x</p></figcaption></figure>
BTC/USD's maximum leverage is 1001x.
You can manually set your leverage before opening a position, ranging from 1x up to 1001x, depending on the specific market.
**Increasing leverage:** Boosts your position size without additional margin but brings the liquidation price closer to your entry point.
**Decreasing leverage:** Reduces your position size and moves the liquidation price further from your entry, lowering risk.
### **Leverage and Position Management**
**Leverage below 500×:**
* You can add margin to open positions
* An open/close position fee of 0.08% applies
**Leverage of 500× and above:**
* Adding margin to open positions is not supported
* Maximum net profit ROI is capped:
* Approximately 500% for 500× and 750× leverage
* Approximately 300% for 1001× leverage
### **Market-Specific Leverage and fFees**
#### **BTCUSD**
* Up to 1001× leverage
* For 500×, 750×, and 1001× leverage:
* 0% open position fee
* Lower price slippage
* A dynamic PnL fee is applied when closing positions. This fee is designed to charge fees based on profit and loss, aiming to protect traders from excessive losses.
* Adding margin to open positions is not supported
* Maximum net profit ROI:
* Approximately 500% for 500× and 750× leverage
* Approximately 300% for 1001× leverage
* For leverage below 500×:
* 0.08% open/close position fees
* Margin can be added to open positions
#### **ETH/USD**
* Up to 250× leverage
* 0.08% open/close position fees
* Margin can be added to open positions
#### **Other Crypto Perpetual Contracts**
* Up to 75× leverage
* 0.08% open/close position fees
* Margin can be added to open positions
#### **Forex Perpetual Contracts**
* Up to 200× leverage
* 0.02% open/close position fees
* Margin can be added to open positions
### **Leverage Example**
Suppose you have $100 in your wallet and open a long BTC position at $20,000 using 10x leverage. Your position size becomes $1,000. If BTC's price increases by 5% to $21,000, your profit is $50, yielding a 50% return on your $100 margin. By contrast, a 5% price drop would result in a 50% loss.

For 1001x

### **Opening Position Fee**
A 0.08% fee is charged when opening a position, calculated as:
> *Opening fee = Number of contracts × Entry price × Opening fee rate*
**Example**
If a trader on BNB Chain opens a 1 ETHUSD long position at $1,500:
> Opening fee = 1 × 1,500 × 0.08% = $1.20
### **Closing Position Fee**
A 0.08% fee is also charged when closing a position, calculated as:
> *Closing fee = Number of contracts × Close price × Closing fee rate*
**Example**
If the same trader closes the 1 ETHUSD position at $1,600:
> *Closing fee = 1 × 1,600 × 0.08% = $1.28*
### **Dynamic PnL-Based Close Fee**
For positions using 500×, 750×, or 1001× leverage, no opening fee is charged. Instead, a dynamic closing fee is applied, calculated based on the realized PnL.
The minimum closing fee under this model is 0.03%.
Where:
* PnL = Profit or loss on the position
* Share rate = Percentage of notional paid in fees (e.g. 15%)
* Notional = Value used to open the position
* Close min rate = Minimum fee rate applied (e.g. 0.03%)
Example
If the position has a $100 profit, share rate is 15%, and notional is $600:
