Frequently Asked Questions

Predict Bay is a prediction market platform built on the Sui blockchain. You can make predictions on whether crypto prices will go higher or lower over specific timeframes. If your prediction is correct when the market resolves, you win. All trades are executed on-chain through smart contracts, ensuring transparency and fairness.

Unlike traditional trading where you buy and hold assets, Predict Bay lets you predict price direction without owning the underlying asset. You're not exposed to unlimited downside—you know exactly what you can win or lose before placing a trade. Markets have fixed resolution times (hourly or daily), making it simpler to manage your positions.

We offer prediction markets on popular cryptocurrencies like Bitcoin (BTC), Ethereum (ETH), Solana (SOL), and more. New markets are added regularly based on community demand.

Predict Bay is built on Sui, a high-performance Layer 1 blockchain. Sui offers instant transaction finality, low fees, and high throughput—making it ideal for prediction markets where speed and reliability matter. All market settlements and fund transfers happen on-chain.

Predict Bay is accessible globally, but it is your responsibility to ensure that using prediction markets complies with the laws in your jurisdiction. We do not provide services in jurisdictions where prediction markets are explicitly prohibited. Please review our Terms of Service for more details.

Creating an account is simple and takes under 60 seconds. Click 'Start Predicting' and sign in with your Google account using our secure ZK Login technology. No crypto wallet, seed phrases, or complex setup required—just your Google account.

ZK Login (Zero-Knowledge Login) is a privacy-preserving authentication method that lets you access blockchain applications using your existing Google account. Your Google credentials are never exposed to the blockchain—only a cryptographic proof that you're authorized. This means you get the security of crypto with the convenience of Web2 login.

No, you don't need a traditional crypto wallet. When you sign up with Google through ZK Login, we automatically create a secure wallet address for you on the Sui blockchain. All your funds and trades are managed through this address. You can export your wallet if needed, but it's optional.

After signing in, navigate to your Portfolio page and click 'Deposit'. You can fund your account using USDC on the Sui network. If you don't have USDC on Sui, you can bridge assets from other chains or purchase directly through our integrated on-ramp partners.

You can start trading with as little as $1 USDC. We recommend starting with smaller amounts while you learn how the platform works. There's no minimum deposit requirement—deposit whatever amount you're comfortable with.

From the Markets page, select an asset you want to trade (e.g., BTC/USD). Choose 'Higher' if you think the price will go up, or 'Lower' if you think it will go down. Enter your trade amount, review the potential payout, and confirm. Your prediction will resolve at the market's expiry time.

Hourly markets resolve at the end of each hour—you predict whether the price will be higher or lower compared to the starting price when the hour ends. Daily markets resolve at the scheduled market close, giving you a longer timeframe for your prediction.

We use trusted decentralized price oracles, published on Sui, to fetch real-time market prices. These prices are fetched on-chain and are publicly verifiable. The starting price is locked when the market opens, and the closing price is fetched from the same oracle at resolution time, ensuring fair and transparent outcomes.

If the closing price is exactly equal to the opening price (no change), the market resolves as 'No Change' and all trades are refunded minus a small protocol fee. This is extremely rare due to price precision but is handled fairly.

Currently, positions cannot be exited early once placed. When you make a prediction, you're committing to hold until resolution. We're exploring secondary market features that may allow position trading in future updates.

Payouts depend on the market dynamics at the time you place your trade. When more people predict 'Higher', the payout for 'Lower' increases, and vice versa. You always see your potential payout before confirming a trade. Winning trades receive their payout automatically when the market resolves.

Yes, maximum trade sizes vary by market and are designed to ensure market integrity and sufficient liquidity. High-volume markets like BTC and ETH typically have higher limits. You'll see the maximum allowed amount when placing a trade.

Our smart contracts include safeguards for edge cases. If oracle feeds are unavailable or delayed, markets may be extended or resolved manually based on the most recent valid price. In cases of critical failures, affected markets may be cancelled and funds refunded. All resolution rules are defined in our smart contracts.

Your funds are managed by audited smart contracts on the Sui blockchain—we never hold custody of your assets. All deposits, trades, and withdrawals are executed on-chain, meaning only you control your funds through your authenticated account. There's no central party that can freeze or access your balance.

Yes, our smart contracts undergo rigorous security audits by reputable third-party firms before deployment. Audit reports are published publicly for transparency. We also maintain an active bug bounty program to encourage responsible security research.

DeepBook is Sui's native on-chain order book infrastructure. We leverage DeepBook for efficient order matching and settlement. This means all trades are matched and settled directly on-chain, eliminating the need for a centralized matching engine and ensuring complete transparency.

No. Market outcomes are determined algorithmically based on oracle price feeds from on-chain oracles—no human intervention is possible. on-chain oracle aggregates prices from multiple institutional sources, making manipulation extremely difficult. All resolution logic is encoded in immutable smart contracts.

We collect minimal data necessary to operate the platform. Your trading activity is public on the blockchain by nature. We may collect email addresses for notifications and analytics data to improve the product. We never sell personal data to third parties. See our Privacy Policy for full details.

Because your funds are held in smart contracts on the Sui blockchain—not in our custody—you retain access to your funds even if our frontend goes offline. You can interact directly with the smart contracts through any Sui-compatible interface or wallet to withdraw your balance.

We primarily accept USDC on the Sui network. If you have USDC on other chains like Ethereum or Solana, you can bridge them to Sui using supported bridges. We're working on integrating additional stablecoins and fiat on-ramp options.

Deposits on Sui are near-instant—typically confirmed in under 2 seconds. Once confirmed on-chain, your balance is immediately available for trading. If bridging from another chain, additional time may be required depending on the bridge used.

Navigate to your Portfolio page and click 'Withdraw'. Enter the amount and your destination Sui address. Withdrawals are processed on-chain within seconds. There are no withdrawal delays or holding periods—your funds are always accessible.

Predict Bay does not charge fees for deposits or withdrawals. You only pay the standard Sui network gas fee (typically less than $0.01). Trading fees are transparently shown before you confirm each trade.

Blockchain transactions are irreversible. If you send funds to an incorrect address, we cannot recover them. Always double-check addresses before confirming any transfer. We recommend doing a small test transaction first when using a new address.

Yes, you can withdraw USDC from any exchange that supports the Sui network directly to your Predict Bay wallet address. Make sure to select 'Sui' as the network when withdrawing. Some exchanges may take time to add Sui support—check with your exchange.

You earn 1 point for every $1 traded on the platform. Points accumulate automatically as you trade—no special actions required. Both winning and losing trades earn points based on the trade amount, so active participation is always rewarded.

Points determine your position on the weekly leaderboard. Top performers on the leaderboard share in weekly prize pools. Points may also qualify you for future $PBAY token airdrops and exclusive platform features as we expand our rewards program.

The leaderboard ranks users by points earned during each weekly period (Monday to Sunday UTC). At the end of each week, the top performers share a prize pool. Your rank is visible on the Leaderboard page, and weekly prizes are distributed automatically.

$PBAY is the planned governance token for the Predict Bay ecosystem. Token holders will be able to participate in protocol decisions, vote on new market listings, and access exclusive features. The token is not yet live—join our community for launch updates.

We're developing a referral program that will reward you for bringing new traders to the platform. You'll be able to earn a percentage of trading fees from users you refer. Stay tuned for the official launch—details will be announced on our socials.

Points earned during a weekly period are used for that week's leaderboard calculations. Historical point totals are tracked and may be used for future rewards, airdrops, or loyalty benefits. Specific point mechanics may evolve as we expand the rewards program.
