Does Polymarket Support Open Banking in the UK?
Polymarket itself does not offer native Open Banking connectivity. That said, numerous UK-based cryptocurrency platforms that convert GBP into USDC do integrate Open Banking rails, enabling rapid, cost-free transfers. This pathway—GBP → USDC → Polymarket—proves considerably more efficient and economical than conventional wire arrangements.
Exchanges Using Open Banking for GBP Deposits
- Coinbase UK: Offers Open Banking via Plaid to facilitate instantaneous GBP deposits with zero charges
- Kraken: Integrates Open Banking for GBP transfers across eligible UK financial institutions
- Revolut: Provides near-instantaneous internal movement; Open Banking integration is optional
How to Use Open Banking to Fund Polymarket
- Step 1: Within Coinbase UK, navigate to "Add funds" and choose "Open Banking"
- Step 2: Verify your identity through your financial institution (Barclays, HSBC, Lloyds, Monzo, and others)
- Step 3: Initiate a GBP transfer—funds arrive at Coinbase within moments (usually 60 seconds or fewer)
- Step 4: Exchange your GBP for USDC on the Polygon chain
- Step 5: Send to your MetaMask wallet and subsequently fund your Polymarket account
Benefits of Open Banking vs Traditional Bank Transfer
Open Banking transactions typically settle immediately (compared to the 2-hour window for standard Faster Payments), carry no deposit surcharge, and eliminate manual entry of sort codes and account identifiers—thereby minimising the likelihood of transfer errors.
Which UK Banks Support Open Banking for Crypto?
The majority of prominent UK financial institutions comply with Open Banking standards under the FCA's PSD2 regulatory framework: Barclays, HSBC, Lloyds, NatWest, Santander, Monzo, Starling, and Revolut all permit Open Banking authorisation protocols.
