Does Polymarket Support Open Banking in the UK?
Polymarket itself does not offer native Open Banking functionality. That said, numerous UK-based cryptocurrency platforms that convert GBP into USDC do integrate Open Banking, enabling rapid and cost-free fund transfers. This pathway—moving GBP through Open Banking to USDC and then into Polymarket—proves considerably more efficient and economical compared to conventional wire transfers.
Exchanges Using Open Banking for GBP Deposits
- Coinbase UK: Integrates Open Banking through Plaid, permitting immediate GBP deposits without charges
- Kraken: Offers Open Banking compatibility for GBP across participating UK financial institutions
- Revolut: Delivers near-instantaneous internal transfers; Open Banking integration 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: Complete authentication using your banking credentials (Barclays, HSBC, Lloyds, Monzo, and others)
- Step 3: Initiate a GBP transfer—funds reach your Coinbase account within seconds (usually 60 seconds or less)
- Step 4: Exchange your funds for USDC on the Polygon blockchain
- Step 5: Send to your MetaMask wallet and then deposit into Polymarket
Benefits of Open Banking vs Traditional Bank Transfer
Open Banking transfers deliver near-instantaneous settlement (in contrast to the 2-hour window typical of standard Faster Payments), incur zero deposit fees, and eliminate the need to manually input sort codes and account numbers—thereby minimising the likelihood of transfer errors.
Which UK Banks Support Open Banking for Crypto?
The vast majority of prominent UK financial institutions comply with Open Banking standards established by the FCA's PSD2 regulation: Barclays, HSBC, Lloyds, NatWest, Santander, Monzo, Starling, and Revolut all provide Open Banking authentication support.
