Getting Started on Polymarket
What it is
Getting started on Polymarket usually means choosing an account path, setting up or connecting a wallet flow, and funding the account in a way Polymarket supports.
Why it matters
Understanding how to properly fund a Web3 wallet is the single biggest hurdle for new prediction market traders. In traditional finance, you link a bank account. On Polymarket, if you send the wrong cryptocurrency (like Ethereum) or use the wrong network (like the Ethereum Mainnet instead of Polygon), your funds will be completely inaccessible for trading and expensive to recover.
How it works
The safe way to think about onboarding is:
- confirm you are eligible to use the platform
- create or connect the account and wallet flow Polymarket supports
- fund the account with the supported asset and network
- verify the balance before trading
Step 1: Account Creation
Polymarket supports more than one onboarding path.
- Integrated sign-up flow: Users may start through Polymarket's built-in account flow, which can create a wallet-backed experience behind the scenes.
- External wallet flow: More advanced users may prefer connecting their own wallet if the platform supports it for their setup.
Step 2: Funding Your Wallet
Once your account path is ready, you need to fund it using the supported asset and network described in Polymarket's current help documentation.
- Integrated purchase flow: This is often the simplest for beginners, though fees can be higher.
- Exchange withdrawal flow: This can be cheaper, but it creates more room for network and asset mistakes.
- Crypto-native transfer flow: This is useful for experienced users, but it is also where beginners make the most expensive errors.
Example
Let's walk through the exchange-withdrawal logic:
- Buy the supported stablecoin on an exchange.
- Copy your destination address from Polymarket.
- Double-check the supported network before sending.
- Send a small test amount first if you are new.
- Confirm the balance is visible before trading size.
Risks
- Network Errors: If you withdraw USDC from an exchange to your Polymarket address but select the Ethereum network, the funds will arrive safely, but Polymarket will not recognize them. You will have to pay expensive Ethereum gas fees to bridge them over to Polygon manually.
- Wallet Security: If you use MetaMask, you are entirely responsible for securing your 12-word seed phrase. If you lose it, or someone steals it, Polymarket cannot recover your funds.
- Third-Party Onramps: If you use a credit card onramp, ensure your bank doesn't flag cryptocurrency purchases as cash advances, which can trigger surprise fees.
- Eligibility mistakes: Do not fund an account before confirming that your jurisdiction is currently supported.
FAQ
Q: Can I deposit Bitcoin or Ethereum directly? Do not assume so. Check the current supported assets and funding instructions in Polymarket's help center before sending anything.
Q: Is there a minimum deposit? The practical minimum depends more on the payment rail or exchange you use than on a simple headline number.
Q: What is the biggest beginner mistake? Funding first and checking the supported asset, network, and eligibility later.
