Starmark uses a simple and intuitive “share” trading mechanism. Each share is priced between $0 and $1. If the predicted outcome occurs, each share settles at $1.00; otherwise, it becomes worthless. Below is the complete trading process:

1. Deposit Funds into Your Account

• After logging in, click the “Deposit” button.

• Recommended methods:

o Direct Transfer: Send USDT (on BNB Chain) to the exclusive deposit address displayed by the system.

o Cross-Chain Deposit: Supports transferring USDC or USDT from Ethereum, Base, Arbitrum, and other chains. The system will automatically bridge and convert them to USDT on BNB Chain.

o For users without crypto: Purchase USDT on centralized exchanges such as Binance, then transfer it in.

• Once the deposit is successful, funds will be credited to your proxy wallet automatically (usually within a few minutes). You can check transaction status on BscScan.

Important: Do not send any assets other than USDT. Otherwise, the funds may not be recoverable.

2. Select a Market

• Go to the “Markets” page.

• Use filters, the search box, or categories (Politics, Economics, Sports, Cryptocurrency, Stocks, etc.) to find markets of interest.

• Click on a market card to enter the details page, where you can view:

o Market rules and settlement conditions

o Deadline

o Current odds (Yes/No or multi-outcome)

o Real-time order book

3. Place an Order (Buy Shares)

The trading panel is located on the right side of the market details page and supports two order types: Market Order and Limit Order.

Market Order (Immediate Execution)

1. Select the betting direction (Yes / No or specific outcome).

2. Enter the USD amount you wish to spend (minimum $1), or switch to entering the number of shares.

3. Click “Bet” / “Buy”.

4. The system will immediately match the order from the order book at the best available price.

o The interface will display estimated slippage and large-order risk warnings.

Limit Order (Specified Price)

1. Switch to Limit Order mode.

2. Select the betting direction.

3. Enter your desired limit price (e.g., $0.90).

4. Enter the amount in USD or number of shares.

5. Choose order validity:

o GTC (Good-Til-Canceled): The order remains active until executed or manually canceled.

o IOC (Immediate-Or-Cancel): Attempts immediate execution; any unfilled portion is automatically canceled.

6. Click “Bet” / “Buy”.

o The order will only execute when someone sells at your limit price or better.

o Partial fills are supported; remaining quantity stays on the order book.

4. Manage Positions

• Go to the “Portfolio” page to view all your holdings.

• You can sell shares at any time before market settlement to lock in profits.

• The selling process is identical to buying — simply switch to the sell direction.

5. Market Settlement and Profit Calculation

• After the event ends, the platform automatically settles based on official results.

• Winning shares: Each share receives $1.00.

• Losing shares: Value drops to $0.00.

• Your profit = (1.00 − Purchase Price) × Number of Shares Held.

Zero Gas Fee Reminder: The platform sponsors gas fees for all trades. You only pay minimal BNB Chain gas fees during deposits and withdrawals, providing a truly low-threshold trading experience.
