Does Polymarket Support Open Banking in the UK?
Polymarket itself does not offer native Open Banking functionality for UK users. That said, numerous UK-based cryptocurrency platforms that convert GBP into USDC do integrate Open Banking, enabling rapid and costless transfers. This pathway—GBP → USDC → Polymarket—delivers superior speed and lower costs relative to conventional wire transfers.
Exchanges Using Open Banking for GBP Deposits
- Coinbase UK: Offers Open Banking through Plaid for rapid GBP deposits — zero cost
- Kraken: Integrates Open Banking for GBP (available at participating UK financial institutions)
- Revolut: Transfers within the platform happen nearly instantaneously; Open Banking is unnecessary
How to Use Open Banking to Fund Polymarket
- Step 1: In Coinbase UK, go to "Deposit funds" → "Open Banking"
- Step 2: Log in through your bank (Barclays, HSBC, Lloyds, Monzo, and others)
- Step 3: Initiate a GBP transfer — funds land in your Coinbase account within moments (usually 60 seconds or less)
- Step 4: Exchange your funds for USDC on the Polygon chain
- Step 5: Send to your MetaMask wallet → complete your Polymarket deposit
Benefits of Open Banking vs Traditional Bank Transfer
Open Banking transactions typically settle within seconds (compared to roughly 2 hours for standard Faster Payments), carry zero deposit charges, and eliminate the need to manually input sort codes or 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 support Open Banking under the FCA's PSD2 directive: Barclays, HSBC, Lloyds, NatWest, Santander, Monzo, Starling, and Revolut all facilitate Open Banking authentication.
