Method 2: Crypto Transfer (Cheapest)
If you already have cryptocurrency, transferring USDC directly is the most cost-effective option. The key is using the Polygon network, not Ethereum mainnet.
Critical: Use Polygon Network
Polymarket uses USDC on Polygon (MATIC). If you send USDC on Ethereum mainnet to your Polygon address, you will lose your funds. Always double-check the network!
Option A: Send USDC from an Exchange
Coinbase: Supports Polygon USDC withdrawals. Select "Polygon" as the network when withdrawing.
Binance: Withdraw USDC and select "Polygon" network. Fees are typically $0.10.
Kraken: Select Polygon when withdrawing USDC. Very low fees.
Step-by-Step: Coinbase to Polymarket
- 1.In Polymarket, click "Deposit" → "Crypto" → Copy your wallet address
- 2.In Coinbase, go to USDC → Send
- 3.Paste your Polymarket address
- 4.Select "Polygon" as the network (not Ethereum!)
- 5.Enter amount and confirm. Arrives in 2-5 minutes.
Option B: Bridge from Ethereum
If you have USDC on Ethereum mainnet, you'll need to "bridge" it to Polygon. Polymarket has a built-in bridge, or you can use external bridges.
Polymarket Built-in Bridge
Click "Deposit" → "Bridge from Ethereum". Takes 7-20 minutes. Fee: ~$5-15 (gas dependent).
External Bridges (Faster)
Use Hop Protocol, Across, or Stargate for faster bridging (2-10 minutes). Fees vary based on congestion.
Method 3: Bank Transfer (Best for Large Amounts)
For deposits over $1,000, bank transfers offer the lowest fees. The process depends on your region and the on-ramp provider.
US Residents (ACH)
Use MoonPay or Transak's bank transfer option. Takes 1-3 business days. Fees: 1-2%.
EU Residents (SEPA)
SEPA transfers are supported through most on-ramps. Takes 1-2 business days. Fees: typically under 1%.
Other Regions
Availability varies. Check MoonPay or Transak for supported payment methods in your country.

Troubleshooting Common Issues
Deposit Not Showing Up
Wait 5-10 minutes. If using a bridge, it can take up to 20 minutes. Check the transaction on Polygonscan to confirm it was sent to the correct address.
Card Declined
Some banks block crypto purchases. Try a different card, or call your bank to authorize the transaction. Using a debit card often has better success rates.
Sent to Wrong Network
If you sent USDC on Ethereum to a Polygon address, the funds may be recoverable but require advanced steps. Contact support immediately.
KYC Rejected
Ensure your ID photo is clear and matches the name on your account. Try using a passport instead of a driver's license.
Security Tips for Depositing
Always Copy Addresses
Never type wallet addresses manually. Copy and paste to avoid typos.
Send Test Transaction First
For your first deposit, send a small amount ($5-10) to verify everything works.
Verify the Website
Always check you're on polymarket.com (not a phishing site). Bookmark the real site.
