You only need USDC. **What do I need to fund my account?** USDC on Polygon sent to your Safe address, or any supported token on any supported chain converted through the built in cross chain route. **Why is my deposit not showing yet?** Prophet reads confirmed on chain events, so a deposit appears once Polygon has confirmed it. That is usually minutes and longer if the network is congested. **Can I create my own market?** Yes. Write a verifiable yes or no question with a resolution date and the pricing ensemble generates calibrated odds, typically in under thirty seconds. ## Costs **What does it cost to trade?** The spread between the buy and sell price, which is currently around twenty percent and can vary by the risk profile of the market. It is already inside the quoted prices rather than charged separately. **Do I pay gas?** No. Prophet absorbs all Polygon gas, so you never need to hold MATIC. You do pay bridging fees and source chain gas on cross chain deposits, because those are external. **Why did I receive less than I bridged?** Bridging fees and source chain gas are deducted from the amount you send. The quote shown before you submit is the amount that will actually arrive. ## Resolution and payouts **How long until I get paid?** In the best case, resolution begins three hours after the market's resolution time and payouts become claimable twelve hours after the outcome is posted. If the ensemble needs retries, add up to about two days. **Can Prophet speed up my payout?** No. The twelve hour review window is enforced by the resolution contract on Polygon, not by Prophet's servers. **Who decides the outcome?** An ensemble of models reading the market's stated resolution source, cross checked against each other, with human review as a fallback when they cannot converge. **What if the models get it wrong?** The buffer, ensemble cross checking, retry loop and review window exist to make that rare. It is not impossible: models can share the same misinformation, and once the review window closes a finalised payout is irreversible. **What happens if a market cannot be resolved?** It can be voided, and every share on both sides redeems for fifty cents. That is a symmetric release of the collateral, so it is a loss if you paid more than fifty cents and a gain if you paid less. **Do my winning shares expire?** No. They sit in your Safe and remain redeemable indefinitely. They earn nothing after resolution, so redeem when you can. ## Custody and security **Does Prophet hold my money?** No. Your USDC and shares sit in a Gnosis Safe on Polygon that you own. Prophet cannot move funds without your signature. **I signed in with a wallet. Where do I send funds?** To your Safe address, which is different from your external wallet address. Funds sent to your external wallet will not appear as a Prophet balance. **What if I lose access to my email login?** Recovery runs through Privy, which holds the key, not through Prophet. Treat that login with the same care as a seed phrase. **Can Prophet reverse a mistaken withdrawal?** No. The destination is locked when you sign and on chain transfers are final. Check the address carefully. ## Trading **Can I sell before the event happens?** Yes. Positions have a live market value and you can exit at any point before resolution to take a gain or cut a loss. **Can I hold both YES and NO?** Yes, and they are treated as two independent positions. This is how you hedge without closing your original position. **Why was my order rejected on size?** Per trade size limits depend on market liquidity and account status, and exist so a single trade cannot move a thin market so far that later traders get bad fills. **My balance looks fine but my trade will not go through.** The interface is still catching up to on chain state. Wait a moment and refresh, and the displayed balance will reconcile with what the chain holds. ## Availability **Can I use Prophet in the United States?** No. Prophet is not available to US citizens or residents. **Is Prophet available everywhere else?** No. Prediction markets have varying legal status and Prophet is unavailable in some other regions. Confirm the position where you are before depositing. --- # Agent Instructions This documentation is published with GitBook.
