Polymarket's Crypto Stack
| Component | Technology | Purpose |
|---|---|---|
| Currency | USDC (Circle) | Stable value for trading |
| Blockchain | Polygon (MATIC) | Fast, cheap transactions |
| Smart Contracts | Solidity/EVM | Trustless market logic |
| Wallet | MPC (Magic) | Secure key management |
| Oracle | UMA Protocol | Market resolution |
| Order Book | CLOB (Off-chain) | Fast order matching |

USDC: The Currency of Polymarket
USDC (USD Coin) is a stablecoin pegged 1:1 to the US Dollar. Every USDC token is backed by cash and short-term US Treasury bonds held in reserve. This makes it ideal for prediction markets because traders don't have to worry about cryptocurrency volatility affecting their positions.
USDC Key Facts
| Attribute | Details |
|---|---|
| Issuer | Circle (co-founded with Coinbase) |
| Market Cap | $30+ billion (2nd largest stablecoin) |
| Backing | 100% cash + US Treasury bonds |
| Audits | Monthly attestations by Deloitte |
| Regulation | State money transmitter licenses |
| Polymarket Network | Polygon (not Ethereum mainnet) |
Why USDC Instead of ETH or BTC?
Polymarket uses USDC rather than volatile cryptocurrencies like ETH or BTC for several reasons:
Volatile Crypto Problems
- Price Risk: If you bet $100 in ETH and ETH drops 20%, your winnings are worth less
- Accounting Nightmare: Constantly fluctuating account value
- Tax Complexity: Every trade triggers capital gains calculations
- Psychological Barrier: Hard to assess true position value
USDC Benefits
- Stable Value: $1 = $1 - always
- Easy Math: Portfolio value = number of USDC
- Clear P&L: Profit and loss in dollar terms
- Familiar Units: Think in dollars, not fractions of ETH

Polygon Blockchain Explained
Polymarket runs on Polygon, a Layer 2 scaling solution for Ethereum. This choice is critical to the platform's usability - Ethereum mainnet would make trading prohibitively expensive.
Ethereum vs Polygon Comparison
| Factor | Ethereum Mainnet | Polygon |
|---|---|---|
| Gas per Trade | $5-50 | $0.001-0.01 |
| Transaction Speed | 12-60 seconds | 2-5 seconds |
| Throughput | 15-30 TPS | 7,000+ TPS |
| Security | Maximum | Very High (inherits from ETH) |
| USDC Liquidity | Highest | High (official Circle support) |
How Polygon Works
Polygon is a "commit chain" that batches many transactions together before anchoring them to Ethereum mainnet. This provides:
- Speed: Transactions confirm in seconds, not minutes
- Cost: Gas fees measured in fractions of a cent
- EVM Compatibility: Same tools, wallets, and smart contracts as Ethereum
- Bridge Security: Polygon PoS bridge secured by validators
Important: Use Polygon Network
When sending USDC to Polymarket, you MUST use the Polygon network. Sending USDC on Ethereum mainnet will not work and could result in lost funds. Always verify the network before withdrawing from exchanges.

|---|---|---|---|
| Email Login (MPC) | Good | Excellent | Most users |
| MetaMask | Very Good | Good | Crypto natives |
| WalletConnect | Very Good | Good | Mobile wallet users |
| Hardware Wallet | Excellent | Fair | Large balances |
Security Best Practices
Do
- Enable 2FA on your email
- Use unique password for Polymarket email
- Verify addresses before sending
- Start with small test transactions
- Keep track of your deposit addresses
- Use hardware wallet for large amounts
Don't
- Share your private keys or seed phrase
- Click links in suspicious emails
- Store large amounts long-term
- Use public WiFi without VPN
- Ignore security warnings

Understanding Gas Fees
Gas fees on Polygon are negligible compared to Ethereum mainnet. This is a major advantage for active traders who make many transactions.
Polygon Gas Costs
| Action | Typical Gas (MATIC) | USD Equivalent |
|---|---|---|
| Buy Shares | 0.001-0.005 | $0.001-0.005 |
| Sell Shares | 0.001-0.005 | $0.001-0.005 |
| USDC Transfer | 0.0005-0.002 | $0.0005-0.002 |
| Approve Token | 0.0005 | $0.0005 |
| Claim Winnings | 0.002-0.01 | $0.002-0.01 |
Getting MATIC for Gas
While gas fees are tiny, you still need a small amount of MATIC in your wallet:
- Polymarket Faucet: May provide small MATIC for new users
- Exchange Withdrawal: Withdraw small amount of MATIC when you get USDC
- Matic Faucet: Various free faucets provide tiny amounts
- Recommended Amount: 0.1-1 MATIC is enough for thousands of transactions
Pro Tip: Gas Optimization
Polymarket batches certain operations to minimize gas costs. Additionally, using limit orders instead of market orders can result in better gas efficiency. For active trading, consider keeping 1-2 MATIC in your wallet to avoid ever running out.

Frequently Asked Questions
What cryptocurrency does Polymarket use?
Polymarket uses USDC (USD Coin), a stablecoin pegged 1:1 to the US Dollar. USDC is chosen because it maintains stable value, unlike volatile cryptocurrencies like BTC or ETH. All USDC on Polymarket is on the Polygon network, not Ethereum mainnet.
Do I need to understand crypto to use Polymarket?
Basic understanding helps, but Polymarket has simplified the process significantly. You can deposit using credit card through MoonPay or Coinbase Pay without managing crypto directly. However, for the best rates and lowest fees, using a crypto exchange like Coinbase to send USDC is recommended.
What network does Polymarket use?
Polymarket runs on Polygon (formerly Matic), a Layer 2 scaling solution for Ethereum. Polygon provides fast, cheap transactions while inheriting Ethereum's security. When sending USDC to Polymarket, always use the Polygon network - sending on Ethereum mainnet will not work.
How much are gas fees on Polymarket?
Gas fees on Polygon are negligible - typically less than $0.01 per transaction. You'll need a small amount of MATIC (the native token of Polygon) for gas, but 0.1-1 MATIC is enough for thousands of trades. Many exchanges offer free or cheap MATIC withdrawals.
Can I use Bitcoin or Ethereum on Polymarket?
No, Polymarket only accepts USDC on Polygon. You'll need to convert BTC or ETH to USDC first. The easiest way is through a centralized exchange like Coinbase: sell your BTC/ETH for USDC, then withdraw the USDC to Polygon. Alternatively, use a DEX like Uniswap on Polygon to swap.
Is my crypto safe on Polymarket?
Polymarket uses industry-standard security practices including MPC (Multi-Party Computation) wallets. Your funds are controlled by smart contracts, not a central database. For maximum security, you can connect your own wallet (MetaMask, hardware wallet) instead of using the email login. See our Polymarket safety guide for details.
What is the minimum deposit for Polymarket?
There's no official minimum, but practical minimums depend on your deposit method. Direct crypto transfers can be as low as $1-5 (plus gas). Card deposits through MoonPay typically have $20-30 minimums. For the best experience, we recommend starting with at least $20-50 to make multiple trades.
How long do deposits and withdrawals take?
Crypto deposits and withdrawals on Polygon typically confirm in 2-5 minutes. If you're bridging from another network, add 5-30 minutes depending on the bridge. Card deposits via MoonPay are usually instant after payment confirmation. This is much faster than traditional platforms which take days for bank transfers.
Can I bet on cryptocurrency prices on Polymarket?
Yes! Polymarket offers various crypto prediction markets including Bitcoin price predictions, 15-minute UP/DOWN markets, ETF approvals, regulatory outcomes, and more. The 15-minute markets (BTC, ETH, SOL, XRP) are particularly popular, with millions in daily volume. See our crypto predictions guide.
What happens to my crypto if Polymarket shuts down?
Because Polymarket uses blockchain-based smart contracts, your positions exist on-chain even if the website goes down. You can interact directly with the smart contracts to withdraw funds. However, market resolution depends on the UMA Oracle, which is decentralized and would continue operating. For peace of mind, don't keep more funds on the platform than you're actively trading.
Are there crypto-specific taxes for Polymarket winnings?
Tax treatment varies by jurisdiction. In most countries, Polymarket winnings are taxable as income or capital gains. Using USDC simplifies accounting since 1 USDC = $1, avoiding the complexity of tracking volatile crypto values. Keep records of all transactions. See our Polymarket tax guide for details.
How do I track my Polymarket positions on-chain?
You can view your positions directly on Polygonscan by entering your wallet address. Your position tokens (ERC-1155) will show under the "Token Holdings" tab. For easier tracking, use PolyTrack which provides a dashboard view of your positions, P&L, and trading history with real-time updates.
Conclusion
Polymarket's cryptocurrency infrastructure provides significant advantages over traditional betting platforms: faster deposits and withdrawals, lower fees, global accessibility, and full transparency. While there's a learning curve for crypto newcomers, the benefits are substantial for active traders.
Key takeaways:
- USDC is the currency - stable, 1:1 with USD, no volatility risk
