How to add funds to your Coin98 Futures balance?

To start trading, you'll need to deposit funds into your futures account

Step 1: Open Coin98 Super Wallet → go to the Futures feature;

Step 2: Click on the wallet icon at the top right corner, then select the wallet you want to use for trading.

Step 3: Add Funds. You can add funds in 2 ways:

Option 1: Click Add Funds on the main screen → choose the token you want to

Option 2: Select the token first → tap Add Funds on the token detail screen;

Step 4: Input the amount you want to add → click Add Funds.

Note:

Input amount must be above the minimum and not exceed your balance. Current minimums (set by Hyperliquid rules based on market price):
SOL: 0.2 SOL,
USDC: 5 USDC;
Network fee is required to process your transaction.
- For USDC (Arbitrum), you need ETH (Arbitrum) for network fee.
- When you deposit SOL, it is bridged to Hyperliquid's spot account and automatically converted to USDC. This USDC is then credited to your Hyperliquid perp margin account - no extra steps required. The fee will be deducted from the input amount, so the Available Amount = Input amount - Fee.

Then wait for processing. Do not close the app until you receive a notification confirming that funds have been successfully added to your Futures balance.

You can check the transaction history in the Activities section.

How to open a long or short position?

Step 1: Select the token you want to trade from the list or use the Search bar to quickly find it.

Step 2: Choose the position type:

Long: If you believe the token price will go up
Short: If you believe the token price will go down

Step 3: Enter margin - the amount of funds you put up as collateral. You can input the amount manually or select a percentage of your Available Funds.

Note: The minimum order size is 10$.

If you enter a margin of $2 and apply 5× leverage, your total position size becomes $10, meeting the minimum requirement and allowing you to open the position.

Step 4: Set the desired Leverage directly or scroll horizontally.

Note: The minimum and default leverage is 1x, while the maximum leverage depends on the selected token. Higher leverage increases potential gains, and the risk of liquidation.

Step 5 (Optional): Enable Set take profit or stop loss by toggling on the button

Position

Take profit (TP)

Stop Loss (ST)

Long

Auto-close when price rises to target

Auto-close when price drops below tolerance

Short

Auto-close when price drops to target

Auto-close when price rises above tolerance

Note:

This step is optional, you can enable it later after a position is opened.
You can set only Take Profit, only Stop Loss or both.
Liquidation price is the price at which the position will be auto closed since the margin is insufficient to maintain the trading. The liquidation price is only determined when the input amount is confirmed.
A Stop Loss is effective only if it is set between the Current Price and the Liquidation Price

After enabling this option, you need to set price and % gain for take profit and % loss for stop loss. You can either:

Input Price and the % Gain/Loss is auto calculated based on the input price, with leverage applied, or
Input % Gain/Loss and the price is auto calculated based on the input % Gain, with leverage applied.

By toggling off the button, you can turn off the Auto close option.

Step 6: Click Continue and review the Order Summary. Then select Open Long/Open Short to confirm opening a position

Then wait for it to process. Do not close the app or go to another screen until you receive a success notification.

You can now check your trade history in the Activities section.

Example
If Bob deposited 100$, select BTC/USD and set x10 leverage → the position size is 1000$.
Bob thought BTC will pump in the near future and decided to open a Long position at $100,000.
If BTC price reaches $110,000 (+10%), the position value increases from $1,000 to $1,100 → his profit will be $100$ (100% of your initial margin)
If BTC price drops to $95,000 (- 5%), the position value decreases from $1,000 to $950 → his loss will be $50 (-50% of your initial margin)
Bob thought BTC price will drop in the near future and decided to open a Short position at $100,000.
If BTC price drops to $95,000 (-10%), the position value increases from $1,000 to $1,100 → his profit will be $100$ (100% of your initial margin)
If BTC price rises to $105,000 (+ 5%), the position value decreases from $1,000 to $950 → his loss will be $50 (-50% of your initial margin)

FAQ

1. What is the minimum amount for adding funds and opening position?

The minimum amount for adding funds and position size is set by Hyperliquid rules based on the market price.

For adding funds:

SOL: 0.2 SOL
USDC: 5 USDC

For position size: 10$

2. What is the minimum and maximum leverage per pair?

The minimum leverage is 1x for all supported tokens. The maximum leverage depends on each token, for example, BTC can have leverage up to 40x.

3. Can I add funds with any tokens, or is there a list of supported tokens?

You can deposit the supported tokens only, such as SOL on Solana, USDC on Arbitrum and then they will be automatically converted to USDC for trading.

If you do not have those tokens, you can deposit, swap for them, or buy them directly on Coin98.

4. Can I use Coin98 Futures on the desktop?

Yes, Coin98 Futures is currently available on the web. You can access and start trading via https://coin98.com/futures/hyper

5. Can I adjust Take Profit (TP)/Stop Loss (SL) or Position Size after opening a position?

Yes, you can edit TP/SL and Position size at any time. Other parameters like leverage are not adjustable once the position is opened.

6. What happens if my margin is too low?

Margin is the deposit you put to open and maintain a position. If you put less margin, it means you are using only a small portion of your own funds and relying heavily on borrowed funds from the exchange by setting high leverage to get the same position size. This will make your position easier to be liquidated if price moves against your position's direction. In that case, your position will be automatically closed to ensure the borrowed funds are repaid.

For example, if you only use $100 as margin with 20x leverage, you can open a $2,000 position size, but you are borrowing $1,900. Even a small 5% drop in price would wipe out your $100 and cause liquidation. On the other hand, if you use $1,000 with 2x leverage for the same $2,000 position size, you borrow less, and your position can survive a larger price drop before liquidation.

7. Why can't I withdraw funds from Coin98 Futures?

You still have open positions. Close them before withdrawing.
Your funds are less than the minimum withdrawal amount. Each token has a minimum withdrawal amount (for USDC it is 5 USDC, and for SOL it is 0.2 SOL).

Note: You can only withdraw the amount shown in Available. The actual tokens received = Available - Fee.

8. How long does it take to process adding funds?

The processing time depends on each token

Sol ~ seconds,
USDC ~ a minute,

9. When withdrawing, can I receive a different token than the one I used to add funds?

Yes, the default token displayed for withdrawal is the latest added one, but you can choose which token to receive after withdrawal.

10. Why is my available balance lower than the amount I added?

Because a small portion of your added funds is used to cover the network fee, so:

Available amount = Input Amount -Network Fee.

11. What type of margin does Coin98 Futures support?

Currently, Coin98 Futures only supports Isolated Margin for perpetual. Each position has its own dedicated margin and is independent of other positions in your wallet.

Troubleshooting

1. Trying to add funds but failed, why?

You may leave the screen before the transaction finished. Please stay on the screen until you see a success message.
Your wallet balance is below the minimum required. Top up your wallet, then try again.
Make sure your Internet connection is stable and try to switch to a better one.

2. Why can't I initiate a trade?

Check the minimum/maximum requirements for leverage, price, and size.

3. Why is Auto Close not working?

For Long: TP must be above the market price; SL must be below the market price.
For Short: TP must be below the market price; SL must be above the market price.

4. Why can't I see my funds after depositing?

Force close and reopen the app (kill app) to reload/refresh
Wait a few minutes as it may take some time for transaction to complete.
Check the blockchain explorer to confirm the transaction is successful.

5. What should I do if the app is not responsive?

Update to the latest app version.
Refresh the app and clear cache.
Reconnect your wallet.
Switch to a different network and try again.
