How to Trade Introduction Starmark — Leading Prediction Market on BNB Chain Starmark is BNB Chain’s premier native cryptocurrency prediction platform. It enables users to trade on the final outcomes of real-world events across politics, economics, sports, cryptocurrencies, stock prices, and many other fields. By trading according to your own forecasts, you can monetize your knowledge and insights into future events. Core Features • Extensive Market Coverage: Covers sports events, political developments, financial trends, cryptocurrency movements, stock prices, and more. With continuous hourly and daily markets, you can seize opportunities at any time. If an event you care about is not yet listed, you can create the market yourself. • Fully On-Chain Trading: All operations—including trading, position holding, and final settlement—are deployed on BNB Chain, ensuring full transparency and verifiability. USDT is the primary trading currency (support for additional collateral assets is coming soon), allowing users to benefit from BNB Chain’s low gas fees and fast confirmation times. • Simple and Intuitive Share Mechanism: Each market outcome is represented as “shares” priced between $0 and $1. If the outcome occurs, each share settles at $1.00; otherwise, it expires worthless. Share prices dynamically reflect the market’s consensus probability of the outcome. • Maximum Flexibility: You may open or close positions at any time before the event concludes. Buy shares in advance, sell at any time to lock in profits, or hold until final resolution. Correct judgments can yield up to 100% returns. • Order Book-Driven Model: Liquidity is provided through a central limit order book. Traders with opposing views match directly, making the market fully user-driven and delivering fair, real-time dynamic odds. • Zero Gas Fee Trading Experience: The platform sponsors gas fees for all user transactions. Gas fees are only required for deposits and withdrawals to the in-app wallet, delivering a truly low-barrier, frictionless trading experience. Starmark is committed to building the most popular one-stop prediction platform on BNB Chain, empowering every user to convert their insights into profits and participate in the world’s most advanced prediction markets anytime, anywhere. Welcome to Starmark — Predict the future together with global traders! How to Log In Starmark offers two simple and fast login methods, allowing you to start trading within seconds:
Quick Login with Social Account (Recommended) • Click the “Sign Up” or “Connect” button in the top right corner of the homepage. • Choose your preferred login method: Google account, X (Twitter) account, or Email. • The system will automatically create a smart contract wallet (in-app wallet) for you — no need to manage private keys manually. • After logging in, you will be prompted to set a username (if logging in via X, a suggestion will be provided automatically; you can modify it anytime). • Important: Please securely back up your login method. Account recovery is not possible if access is lost.
Connect with Existing Web3 Wallet • Click “Connect Wallet”. • Select your installed wallet (supports MetaMask, Binance Wallet, OKX Wallet, and other mainstream wallets). • After authorization, the system will prompt you to create a proxy wallet (in-app wallet). All subsequent transactions will be executed through this proxy wallet. • The proxy wallet is deployed on BNB Chain and supports only USDT as the trading currency. After successful login, the system will automatically guide you to the deposit page. Once you complete the deposit, you can begin trading. How to Trade 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:
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.
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

Select the betting direction (Yes / No or specific outcome).
Enter the USD amount you wish to spend (minimum $1), or switch to entering the number of shares.
Click “Bet” / “Buy”.
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)
Switch to Limit Order mode.
Select the betting direction.
Enter your desired limit price (e.g., $0.90).

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.
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.
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.
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.
