Can You Use a Debit Card on Polymarket?
Polymarket does not accept debit cards directly. The platform is crypto-native and only accepts USDC deposits on the Polygon blockchain. However, UK users can easily fund Polymarket using a debit card via a third-party crypto exchange in just a few steps.
How to Deposit via Debit Card (UK)
- Step 1: Create an account on Coinbase, Kraken, or Revolut (all accept UK Visa/Mastercard)
- Step 2: Complete the exchange's KYC (typically instant with a passport or driving licence photo)
- Step 3: Buy USDC with your debit card on the exchange
- Step 4: Withdraw USDC to your MetaMask wallet on the Polygon network
- Step 5: Deposit from MetaMask into your Polymarket balance
Which UK Exchanges Accept Debit Cards?
Most major exchanges operating in the UK accept Visa and Mastercard debit cards for crypto purchases:
- Coinbase UK — Visa/Mastercard, instant, ~1.5% fee
- Revolut — Buy USDC via the app using your Revolut debit card, low fees
- Kraken — Visa/Mastercard, ~1.5% fee, FCA-registered
- Binance UK — Visa/Mastercard, competitive fees
Are There Bank Restrictions?
Some UK banks (notably Starling and some Lloyds products) occasionally block crypto purchases on debit cards. If your transaction is declined, contact your bank to authorise crypto purchases, or use a bank that is crypto-friendly (Revolut, Monzo, Wise).
Total Time: Debit Card to Trading
If your exchange account is already verified: under 10 minutes. New account with instant KYC: approximately 30–60 minutes.
