How to Deposit on Polymarket from the UK
Polymarket enforces geographic restrictions affecting UK-based participants, though PolyGram circumvents this limitation by offering unrestricted access to the identical CLOB order book paired with deposit methods tailored for British users. All prediction contracts ultimately settle via USDC held on the Polygon blockchain.
UK Deposit Methods Available on PolyGram
Bank Transfer (Faster Payments / Open Banking)
British account holders may capitalise their PolyGram balance through Faster Payments infrastructure, facilitated by PolyGram's licensed fiat gateway partner. Deposited sterling converts instantaneously to USDC and reaches your trading account in approximately 5 minutes on average. The floor for any single deposit stands at £10. PolyGram itself levies no charge; the conversion provider applies a margin of 1–1.5%.
Debit & Credit Card
Both Visa and Mastercard payment cards qualify for acceptance. Certain issuers may reject credit card transactions if flagged internally as cash-like withdrawals — debit cards are therefore recommended where available. The on-ramp partner typically charges around 1.8% per transaction.
Klarna
Klarna's deferred-payment service is available to qualified UK residents holding an active Klarna account. The mechanism permits immediate trade execution with settlement deferred across a 30-day window at no interest.
Crypto (USDC, ETH, BTC)
Direct blockchain transfers of USDC to your PolyGram Polygon-based wallet are supported from major custodians including Coinbase, Kraken, and Binance. ETH and BTC transfers trigger automatic conversion to USDC via integrated bridge infrastructure. This pathway delivers the lowest friction and cost for high-frequency traders. Polygon-layer confirmations occur within 60 seconds.
