Funding Methods

To trade on Polymarket, you need USDC on the Polygon network. Polymarket now supports multiple deposit methods including direct USDC deposits and automatic bridging from various blockchains.

Good News: You can now deposit from multiple chains and tokens! Polymarket's integrated bridge automatically converts your assets to USDC on Polygon.

Method 1: Direct Exchange Withdrawal (Lowest Fees - Recommended)

If you already have USDC and your exchange supports Polygon withdrawals, this is the cheapest method with fees typically ranging from $0.10 to $1.

Recommended Exchanges:

• Binance: Supports Polygon USDC withdrawal (~$1 fee). If you don't have a Binance account yet, use our exclusive link to get 20% permanent discount on both spot and futures trading fees.
• OKX: Supports Polygon USDC withdrawal. If you don't have an OKX account yet, use our exclusive link to get 20% permanent discount on both spot and futures trading fees.
• Coinbase: Supports direct Polygon USDC withdrawal (fast, low fees)
• Kraken: Supports Polygon USDC withdrawal

Steps:

1. Buy USDC on your exchange.
2. Go to Withdraw.
3. Paste your Polymarket Address (click your profile → Copy Address).
4. Select Network: Choose Polygon (sometimes labeled as MATIC or Polygon PoS).
5. Confirm withdrawal.

Pros: Lowest fees (typically $0.10-$1).
Cons: Requires an exchange account and verification.

CRITICAL WARNING: When withdrawing from an exchange, ALWAYS select the Polygon network. Do NOT send via Ethereum mainnet directly, as it will require manual bridging later.

💡 Tip: Don't have a Binance or OKX account yet? Sign up for Binance or sign up for OKX using our exclusive links to get 20% permanent discount on trading fees (both spot and futures).

Method 2: Buy with Card (Easiest)

You can buy crypto directly within Polymarket using MoonPay or Transak.

1. Click the Deposit (or Wallet) button.
2. Select Buy with Card.
3. Enter the amount (e.g., $100).
4. Follow the KYC steps with the provider.
5. Your USDC will be deposited on Polygon automatically.

Pros: Fast, easy, no prior crypto needed.
Cons: Higher fees (usually 3-5%).

Method 3: Multi-Chain Deposit

Polymarket now supports deposits from multiple blockchains with automatic bridging!

Supported Chains:

• Ethereum Mainnet
• Solana
• Arbitrum
• Base
• Optimism
• And more...

How it works:

1. Click the Deposit button in Polymarket.
2. Select Multi-Chain Deposit or Bridge.
3. Choose your source chain (e.g., Ethereum, Solana, Arbitrum).
4. Select the token you want to deposit (USDC, ETH, SOL, or other supported tokens).
5. Enter the amount and confirm.
6. Your assets will be automatically bridged and converted to USDC on Polygon.

Pros: Flexible, supports many chains and tokens, integrated experience.
Cons: Bridge fees vary by chain (usually $1-5).

Note: Your deposited assets are automatically converted to USDC.e (bridged USDC) on Polygon, which works seamlessly on Polymarket.

Method 4: Manual Bridging

If you already have USDC on other networks in your personal wallet:

Fast Bridges:

• Across.to (recommended - fast, low fees)
• Polygon Portal (official)
• Stargate Finance

Steps:

1. Go to the bridge website.
2. Connect your wallet (MetaMask, Phantom, etc.).
3. Source: Select your current chain (e.g., Ethereum).
4. Destination: Select Polygon.
5. Token: Select USDC.
6. Enter amount and bridge.
7. Funds usually arrive in 1-10 minutes.

Pros: Full control, works from personal wallets.
Cons: Requires gas fees on source chain.

Do I need MATIC for gas?

No! Polymarket uses a "Meta-Transaction" system (Relayers).

• Polymarket pays the gas fees for your trades.
• You only need USDC to trade - no need to hold MATIC tokens.

Tips for Safe Deposits

1. Always test first: Send a small amount ($5-10) to verify everything works.
2. Double-check the network: Ensure you're using Polygon/Matic network.
3. Save your address: Bookmark or save your Polymarket deposit address for future use.
4. Compare fees: Multi-chain deposits are convenient but check bridge fees vs. direct exchange withdrawals.
