Does Polymarket Support Open Banking in the UK?
Polymarket itself does not offer native Open Banking connectivity. Nonetheless, numerous UK-based cryptocurrency platforms that convert GBP into USDC have integrated Open Banking functionality, enabling rapid, zero-cost fund transfers. This pathway—GBP → USDC → Polymarket—delivers superior speed and cost efficiency compared to conventional wire transfers or BACS payments.
Exchanges Using Open Banking for GBP Deposits
- Coinbase UK: Offers Open Banking via Plaid integration for immediate GBP deposits at no cost
- Kraken: Integrated Open Banking option for GBP transfers (available through participating UK financial institutions)
- Revolut: Peer-to-peer transfers operate with near-instantaneous settlement; Open Banking layer unnecessary
How to Use Open Banking to Fund Polymarket
- Step 1: Within Coinbase UK, navigate to "Add funds" and select "Open Banking"
- Step 2: Verify your identity through your bank's authentication portal (Barclays, HSBC, Lloyds, Monzo, and others)
- Step 3: Initiate a GBP transfer—funds appear in your Coinbase account within moments (usually 60 seconds or less)
- Step 4: Exchange GBP for USDC on the Polygon blockchain
- Step 5: Send USDC to your MetaMask wallet and then transfer into Polymarket
Benefits of Open Banking vs Traditional Bank Transfer
Open Banking transactions typically settle in real time (in contrast to the 2-hour window for standard Faster Payments), carry zero deposit charges, and eliminate the need to manually input sort codes or account identifiers—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 requirements under the FCA's PSD2 directive: Barclays, HSBC, Lloyds, NatWest, Santander, Monzo, Starling, and Revolut each facilitate Open Banking-based authentication flows.
