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 and costless deposits. This arrangement creates a streamlined GBP → USDC → Polymarket route that outperforms conventional wire transfers in both speed and expense.
Exchanges Using Open Banking for GBP Deposits
- Coinbase UK: Integrates Open Banking through Plaid to facilitate immediate GBP deposits — zero cost
- Kraken: Provides Open Banking connectivity for GBP (accessible to eligible UK banking partners)
- Revolut: Transfers within the platform execute near-instantaneously; Open Banking integration is unnecessary
How to Use Open Banking to Fund Polymarket
- Step 1: Within Coinbase UK, navigate to "Add funds" → "Open Banking"
- Step 2: Log in through your financial institution (Barclays, HSBC, Lloyds, Monzo, and others)
- Step 3: Initiate a GBP transfer — funds land in your Coinbase account right away (usually within 60 seconds)
- Step 4: Acquire USDC on the Polygon blockchain
- Step 5: Send to your MetaMask wallet → transfer funds into your Polymarket account
Benefits of Open Banking vs Traditional Bank Transfer
Open Banking transactions typically settle instantly (compared to roughly 2 hours for standard Faster Payments), carry zero deposit charges, and eliminate the need to manually input sort codes or account identifiers — thereby lowering the likelihood of user error.
Which UK Banks Support Open Banking for Crypto?
The majority of leading UK financial institutions comply with Open Banking under the FCA's PSD2 regulatory mandate: Barclays, HSBC, Lloyds, NatWest, Santander, Monzo, Starling, and Revolut all enable Open Banking verification.
