Does Polymarket Support Open Banking in the UK?
Polymarket itself does not offer native Open Banking functionality. That said, numerous UK-based crypto platforms that convert GBP into USDC do integrate Open Banking, enabling swift, zero-cost fund transfers. This pathway—GBP → USDC → Polymarket—delivers superior speed and cost efficiency relative to conventional bank transfer methods.
Exchanges Using Open Banking for GBP Deposits
- Coinbase UK: Integrates Open Banking through Plaid, permitting immediate GBP deposits at no cost
- Kraken: Offers Open Banking connectivity for GBP across eligible UK financial institutions
- Revolut: Delivers near-instantaneous internal movement; 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: Verify your identity with your bank (Barclays, HSBC, Lloyds, Monzo, and others)
- Step 3: Initiate a GBP transfer — funds settle at Coinbase within moments (usually 60 seconds or less)
- Step 4: Acquire USDC on the Polygon blockchain
- Step 5: Send to your MetaMask wallet → complete your Polymarket deposit
Benefits of Open Banking vs Traditional Bank Transfer
Open Banking transactions typically settle instantly (compared to roughly 2 hours via 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 UK's leading financial institutions support Open Banking under the FCA's PSD2 regulatory mandate: Barclays, HSBC, Lloyds, NatWest, Santander, Monzo, Starling, and Revolut all provide Open Banking authentication support.
