Does Polymarket Support Open Banking in the UK?
Polymarket itself does not offer native Open Banking connectivity. That said, numerous UK-based crypto platforms that convert GBP into USDC do integrate Open Banking, enabling rapid, zero-cost fund transfers. This pathway—GBP → USDC → Polymarket—proves considerably more efficient and economical than conventional bank wire methods.
Exchanges Using Open Banking for GBP Deposits
- Coinbase UK: Offers Open Banking via Plaid, permitting immediate GBP deposits at no cost
- Kraken: Integrates Open Banking for GBP transfers from participating UK financial institutions
- Revolut: Provides near-instantaneous internal transfers; Open Banking functionality is unnecessary
How to Use Open Banking to Fund Polymarket
- Step 1: Within Coinbase UK, navigate to "Add funds" and choose "Open Banking"
- Step 2: Log in through your bank's authentication system (Barclays, HSBC, Lloyds, Monzo, etc.)
- Step 3: Initiate a GBP transfer—funds appear in your Coinbase account within moments (usually 60 seconds or less)
- Step 4: Acquire USDC on the Polygon blockchain
- Step 5: Send to your MetaMask wallet → complete your Polymarket deposit
Benefits of Open Banking vs Traditional Bank Transfer
Open Banking transactions deliver near-instantaneous settlement (compared to the 2-hour window for standard Faster Payments), eliminate deposit processing charges, and bypass the need to manually input sort codes or account numbers—thereby minimising the likelihood of transfer errors.
Which UK Banks Support Open Banking for Crypto?
The majority of UK's leading financial institutions comply with Open Banking standards under the FCA's PSD2 directive: Barclays, HSBC, Lloyds, NatWest, Santander, Monzo, Starling, and Revolut all facilitate Open Banking authorisation.
