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, zero-cost transfers. 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 to facilitate instant GBP deposits with zero charges
- Kraken: Offers Open Banking connectivity 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: Navigate to Coinbase UK, choose "Add funds" → "Open Banking"
- Step 2: Log in with your banking credentials (Barclays, HSBC, Lloyds, Monzo, and others)
- Step 3: Send GBP funds — settlement occurs immediately at Coinbase (usually within 60 seconds)
- Step 4: Acquire USDC on the Polygon blockchain
- Step 5: Move funds to your MetaMask wallet → transfer into Polymarket
Benefits of Open Banking vs Traditional Bank Transfer
Open Banking transactions settle instantly (compared to the 2-hour window for standard Faster Payments), carry no deposit fees from the exchange, and eliminate the need to manually input sort codes and account details—thereby minimising the chance of transfer errors.
Which UK Banks Support Open Banking for Crypto?
The vast majority of UK's leading financial institutions facilitate Open Banking under the FCA's PSD2 regulatory mandate: Barclays, HSBC, Lloyds, NatWest, Santander, Monzo, Starling, and Revolut all enable Open Banking authentication.
