Does Polymarket Support Open Banking in the UK?
Polymarket itself does not offer native Open Banking functionality. That said, numerous UK-based crypto platforms that convert GBP into USDC do integrate Open Banking, enabling rapid, zero-cost transfers. This route — funnelling funds from GBP through USDC and into Polymarket — proves quicker and more economical than conventional bank-to-bank transfers.
Exchanges Using Open Banking for GBP Deposits
- Coinbase UK: Offers Open Banking through Plaid for immediate GBP deposits — zero cost
- Kraken: Integrated Open Banking option for GBP (available at select UK financial institutions)
- Revolut: In-app transfers work near-instantaneously; Open Banking integration unnecessary
How to Use Open Banking to Fund Polymarket
- Step 1: Within Coinbase UK, tap "Add funds" → "Open Banking"
- Step 2: Log in via your bank credentials (Barclays, HSBC, Lloyds, Monzo, and others)
- Step 3: Initiate a GBP transfer — funds land at Coinbase within moments (usually 60 seconds or less)
- Step 4: Exchange your GBP for USDC on the Polygon chain
- Step 5: Send to your MetaMask wallet → complete your Polymarket deposit
Benefits of Open Banking vs Traditional Bank Transfer
Open Banking transfers deliver near-instantaneous settlement (compared to 2 hours for standard Faster Payments), incur zero deposit charges, and eliminate the need to manually input sort codes or account details — thereby cutting down on entry mistakes.
Which UK Banks Support Open Banking for Crypto?
