MetaMask has opened sign-ups for the MetaMask Card in the United Kingdom, the company confirmed in an October 20 post on its official account. UK users can now register for the card and spend crypto "anywhere Mastercard is accepted," according to the post.
The MetaMask Card is a self-custodial Mastercard debit card. Unlike a card tied to a centralized exchange balance, it draws funds from a user's own MetaMask wallet at the moment of purchase, settling the on-chain balance into fiat on the Mastercard network. There is no credit line, no APR, and no requirement to pre-fund a custodial account.
The mechanics behind a UK tap
For a British cardholder, the practical shape is simple. Load a supported wallet, link it to the card, and spend. Transactions route through Linea, Base, or Solana depending on the asset. The MetaMask Card supports stablecoins including USDC, USDT, and a GBP-denominated stablecoin, alongside wrapped ETH.
The asset you spend changes the cost. Spending a stablecoin in your local currency carries no conversion fee, so a UK user paying in a GBP stablecoin at a UK merchant pays 0% on that leg. Spending a non-local stablecoin adds 0.5%, and spending wrapped ETH runs 0.875%. Standard on-chain gas also applies at settlement, a cost that does not appear on the card statement itself. The virtual card is free to issue and pays 1% cashback on all transactions.
Self-custody as the selling point
The pitch here is custody, not rewards. Most crypto cards require you to hand assets to the issuer or a partner exchange before you can spend. MetaMask keeps the balance in your wallet until the transaction clears, which removes the counterparty risk of an exchange holding your funds. For users who already treat spending from their own wallet as non-negotiable, that is the entire appeal.
The trade-off is operational. Self-custody means the user is responsible for seed-phrase security and for keeping a fundable balance in the right network. A lost phrase is a lost balance, with no support desk to reverse it. The card also inherits the usual prepaid-style friction: some pre-authorization merchants, such as petrol stations and car-hire desks, can place holds that sit awkwardly against a wallet-funded card.
Another self-custodial option for British users
The UK opening adds another self-custodial option to a market that already has several custodial crypto cards. It does not change the economics of the product, only its reach. UK applicants get the same virtual card terms available across MetaMask's supported markets: free issuance, 1% cashback, and the self-custody model. Prospective users in the United Kingdom should confirm their preferred funding asset and network before ordering, since the fee they pay depends entirely on which token they spend.
Overview
MetaMask has opened MetaMask Card sign-ups in the UK, extending its self-custodial Mastercard debit card to British users. The card spends directly from a MetaMask wallet on Linea, Base, or Solana, with a free virtual tier paying 1% cashback. Local-currency stablecoin spending carries no FX fee; other assets add 0.5% to 0.875% plus on-chain gas. The announcement widens availability without altering the underlying product.
