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 funding flows. This pathway—GBP → USDC → Polymarket—delivers superior speed and cost efficiency relative to conventional wire transfers.
Exchanges Using Open Banking for GBP Deposits
- Coinbase UK: Integrates Open Banking through Plaid, allowing instant GBP deposits with zero fees
- Kraken: Provides Open Banking connectivity for GBP transfers (available to select UK banking partners)
- Revolut: Enables near-instantaneous internal transfers; 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: Log in through your bank provider (Barclays, HSBC, Lloyds, Monzo, and others)
- Step 3: Initiate a GBP transfer—funds land in your Coinbase account in seconds (usually under a minute)
- Step 4: Exchange your GBP for USDC on the Polygon chain
- Step 5: Send to your MetaMask wallet and proceed to fund your Polymarket account
Benefits of Open Banking vs Traditional Bank Transfer
Open Banking transactions settle nearly instantaneously (compared to 2 hours via standard Faster Payments), incur zero deposit charges, and eliminate manual entry of sort codes and account identifiers—thereby minimising the chance of input mistakes.
Which UK Banks Support Open Banking for Crypto?
The vast majority of UK financial institutions comply with the FCA's PSD2 mandate and support Open Banking: Barclays, HSBC, Lloyds, NatWest, Santander, Monzo, Starling, and Revolut all facilitate Open Banking-based authentication flows.
