Can You Fund Polymarket via Bank Transfer?
Polymarket itself does not facilitate direct bank transfers. Instead, the standard approach involves sending GBP through a UK bank to a crypto exchange using Faster Payments, exchanging it for USDC, and then transferring USDC to your self-custody wallet. This pathway typically carries lower costs compared to using a debit card.
Best UK Exchanges for Bank Transfer → USDC
- Coinbase UK: Accepts Faster Payments, zero-fee GBP inbound transfers, 0.5–1% spread on USDC pairs
- Kraken: Supports GBP via SEPA and Faster Payments, tight USDC conversion margins
- Revolut: Same-day internal settlement, reduced conversion spreads for Premium and Metal subscribers
- Wirex: Accepts sterling deposits, offers USDC conversion at market-competitive rates
Step-by-Step: Bank Transfer to Polymarket
- Step 1: Send GBP via Faster Payments to your selected exchange (settlement typically instantaneous)
- Step 2: Acquire USDC on the Polygon chain (alternatively, obtain USDC on Ethereum and use a bridge — though this adds complexity)
- Step 3: Move USDC from the exchange to your MetaMask account on Polygon
- Step 4: Transfer funds from MetaMask into Polymarket
How Long Does a Bank Transfer Take?
Faster Payments in the UK settle to the receiving exchange in moments, rarely exceeding 2 hours. After arrival, executing the remaining steps—purchasing USDC, moving it off-exchange, and depositing to Polymarket—typically requires fewer than 10 minutes. The entire cycle from bank initiation to active trading usually completes within 3 hours.
Fees Comparison: Bank Transfer vs Debit Card
Bank transfers generally offer superior cost efficiency. The majority of platforms impose no charge for Faster Payments deposits, whereas debit card transactions incur 1–2% fees. For transactions exceeding £500, the bank transfer method almost invariably proves more economical.
