Can You Fund Polymarket via Bank Transfer?
Polymarket does not support direct bank transfer funding. To add funds to your Polymarket account through a bank transfer, you must first send GBP to a UK-compatible crypto exchange using Faster Payments, exchange it for USDC, and then transfer USDC to your self-custody wallet. This approach usually carries lower costs compared to using debit card methods.
Best UK Exchanges for Bank Transfer → USDC
- Coinbase UK: Accepts Faster Payments, zero-cost GBP deposits, 0.5–1% conversion margin
- Kraken: GBP via SEPA or Faster Payments, tight USDC conversion margins
- Revolut: Seamless peer transfers, reduced conversion costs on Premium or Metal membership tiers
- Wirex: Accepts GBP inbound transfers, USDC conversion at attractive spreads
Step-by-Step: Bank Transfer to Polymarket
- Step 1: Send GBP using Faster Payments to your preferred exchange (normally instantaneous)
- Step 2: Acquire USDC on the Polygon blockchain (alternatively, purchase USDC on Ethereum then bridge across — less optimal)
- Step 3: Move USDC from the exchange to your MetaMask Polygon address
- Step 4: Transfer funds into Polymarket using your MetaMask wallet
How Long Does a Bank Transfer Take?
Faster Payments transfers to UK exchanges settle in minutes, rarely exceeding 2 hours. After arrival, completing the remaining steps—acquiring USDC, moving it to your wallet, and depositing into Polymarket—takes roughly 10 minutes or less. The entire journey from initiating your bank transfer to placing your first trade usually concludes within 3 hours.
Fees Comparison: Bank Transfer vs Debit Card
Bank transfers typically offer superior fee economics. Most platforms impose no charge for Faster Payments deposits, whereas debit card transactions incur 1–2% surcharges. When moving sums of £500 or more, bank transfer methodology proves substantially more economical.
