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 funding. This pathway—moving funds from your bank through GBP → USDC → Polymarket—proves considerably more efficient and economical than relying on conventional wire transfers.
Exchanges Using Open Banking for GBP Deposits
- Coinbase UK: Integrates Open Banking through Plaid, allowing immediate GBP deposits with zero charges
- Kraken: Provides Open Banking connectivity for GBP transfers across participating UK financial institutions
- Revolut: Enables near-instantaneous internal transfers; Open Banking integration is unnecessary
How to Use Open Banking to Fund Polymarket
- Step 1: Within Coinbase UK, navigate to "Add funds" and choose "Open Banking"
- Step 2: Complete authentication through your bank (Barclays, HSBC, Lloyds, Monzo, and others)
- Step 3: Initiate your 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 blockchain
- Step 5: Send to your MetaMask wallet and then transfer into your Polymarket account
Benefits of Open Banking vs Traditional Bank Transfer
Open Banking transactions typically settle within moments (compared to the standard 2-hour window for Faster Payments), incur no deposit charges, and eliminate the need to manually input sort codes or account details—thereby minimising the likelihood of entry errors.
Which UK Banks Support Open Banking for Crypto?
The vast majority of UK's leading financial institutions comply with the FCA's PSD2 requirements and provide Open Banking support: Barclays, HSBC, Lloyds, NatWest, Santander, Monzo, Starling, and Revolut all facilitate Open Banking-based authentication.
