# FAQ

> Answers to the most common questions about using Overdog.

<AccordionGroup>
  <Accordion title="Do I need a crypto wallet to use Overdog?">
    No. When you start Overdog for the first time, a wallet is created for you automatically. You don't need to install any wallet app or hold any crypto beforehand. Just send `/start` and you're ready to deposit and trade.
  </Accordion>

  <Accordion title="Is my wallet custodial?">
    No. Your wallet is a non-custodial **Gnosis Safe** deployed on Polygon. Only you hold the private key — Overdog never has access to your funds. You can export your private key at any time with `/export` and use it in any compatible wallet.
  </Accordion>

  <Accordion title="What is Polymarket?">
    Polymarket is a decentralized prediction market platform where you trade on the outcomes of real-world events — sports results, elections, economic indicators, and more. Each outcome is represented as a share priced between $0 and $1. A share pays out $1 if the outcome is correct, and $0 if it's not. Overdog gives you a Telegram interface to trade directly on Polymarket.
  </Accordion>

  <Accordion title="What currency is used?">
    All balances and trades are denominated in **USDC.e** on Polygon, a bridged version of USDC pegged to the US dollar. You can think of $1 in Overdog as $1 USD. When you withdraw, Overdog can convert to other stablecoins (USDT on Tron, USDC on Solana, Ethereum, Arbitrum, or Base) via a bridge.
  </Accordion>

  <Accordion title="What is the minimum trade amount?">
    The minimum trade is **\$1.00**.
  </Accordion>

  <Accordion title="How fast are trades executed?">
    Standard market orders use **Fill-or-Kill (FOK)** — the order is either filled immediately at the best available price or cancelled instantly. Execution typically completes in a few seconds.

    Sports markets may have a brief delay (a few seconds) after you submit while the order is matched. If it doesn't fill within that window, the order is cancelled and you can try again.
  </Accordion>

  <Accordion title="How do I export my private key?">
    Send `/export` in the bot. Your private key appears as a tap-to-reveal spoiler and is automatically deleted from the chat after 30 seconds. Copy it immediately and store it somewhere safe — a password manager or an offline backup.

    <Warning>
      Never share your private key with anyone, including anyone claiming to be from Overdog support. Anyone with your key has full control of your wallet.
    </Warning>
  </Accordion>

  <Accordion title="Why was my trade not filled?">
    Overdog uses Fill-or-Kill orders, which require enough liquidity in the orderbook at the time of submission. If there aren't enough buyers (for a sell) or sellers (for a buy) at an acceptable price, the order is cancelled rather than partially filled or left open.

    To fix this: try a smaller amount, wait for more liquidity to appear, or check back when the market is more active.
  </Accordion>

  <Accordion title="How are resolved positions claimed?">
    Automatically. Overdog monitors for market resolutions in the background. When a market you hold a winning position in resolves, Overdog redeems your shares and adds the USDC proceeds directly to your wallet balance — no action needed on your part.
  </Accordion>

  <Accordion title="What chains are supported for withdrawal?">
    You can withdraw to any of the following:

    * **Polygon** — USDC (native, no bridge fee)
    * **Tron** — USDT (TRC-20)
    * **Solana** — USDC

    Use `/withdraw` to start a withdrawal and select your preferred destination.
