Non-Custodial Crypto Cards: Who Controls the Money?

Can you use a crypto card without leaving your money on an exchange? Yes. A self-custody card can spend from a wallet you control, using permissions you approve. Here’s how that works with MetaMask Card and ether.fi Cash—and what changes if you borrow instead of spending your balance.

Your keys stay with you. What can the card spend?

Your wallet holds the funds; the card gets permission to spend a chosen token. With MetaMask’s wallet setup, you set that allowance and can revoke it. Self-custody does not mean the card has no access to your money.

Wallet control and card access are different
FeatureWhat it means
Wallet keysYou or your wallet’s signers authorize transactions
Token allowanceA token approval authorizes spending up to an allowance
Card accessIssuer and account rules can stop card payments
Borrow modeCollateral backs a loan; interest and liquidation can apply
ExitWallet access and card availability are separate; withdrawal rules depend on the setup
Details and conditions
  • The card issuer still controls card access. A wallet, a spending approval and a loan secured by crypto are three different things.

MetaMask Card: approve an amount, then spend

MetaMask’s US guide describes approving a token spending limit rather than topping up a separate card balance. New US card sign-ups are currently paused; existing holders can keep using their cards. Check the guide for your own region before applying.

  1. Check that new applications are open where you live.
  2. Choose a supported token and network, then set a spending limit.
  3. Try a small purchase and check the settled amount.
  4. Reduce or revoke the allowance when you no longer need it.
Details and conditions
  • Example: you hold 500 USDC but approve only 100 USDC for the card. That allowance limits how much of this token the card can use; it does not move the remaining 400 USDC. Fees and any other approved tokens are separate.

ether.fi Cash: spend your balance or take a loan

Direct Pay spends an eligible balance. Borrow mode takes a loan against your assets when you pay, with interest until repayment. Direct Pay can also have separate borrowing enabled—check both settings.

Two modes with different consequences
ModeWhat a purchase doesWhat you manage
Direct PayPays from the eligible balance.Enough spendable funds; any separately enabled borrowing.
BorrowAdds to a collateral-backed loan.Interest, repayment and the risk of collateral liquidation.
Details and conditions
  • Illustration, before fees: a $50 purchase in Direct Pay uses $50 of spendable funds. In Borrow mode it adds $50 to your debt. If collateral loses value, some can be liquidated even if you make no further purchases.
  • Eligible assets are supplied to ether.fi’s lending market under its documented Borrow setup. Lending settings are separate from your card mode; the guide explains how to opt out and how outstanding debt limits usable funds.

Does self-custody mean you only pay gas?

No. Network fees and card fees are separate. These are selected personal-card charges, not a quote for every purchase. Country, token, merchant location and membership can change what applies.

Selected fees to compare before signing up
CardPublished chargesWhen they matter
MetaMask Free / Metal$0 / $199 annual subscriptionFree: 1% cross-border fee when the merchant is outside your country. Metal waives it subject to fair usage. Token and ATM fees can also apply.
ether.fi CashCore: normally one free virtual card; $10 in specified regionsAdded FX margin outside USD/EUR: Core 0.5%, Luxe 0.25%, Pinnacle/VIP none. This is on top of the base exchange rate.
Network feesVariableDepend on the blockchain and action. A network fee is not an annual membership fee or an FX fee.

Can your wallet survive a card shutdown?

Yes, depending on the arrangement. The legacy Gnosis Pay notice says its card stops on 20 December 2026 while users retain access to their self-custodial Safe. Recurring merchants still need new card details.

Details and conditions
  • A partner program has its own terms. Check its account setup, fees and permissions rather than treating a migration as a simple logo change.

Which setup fits how you use crypto?

For spending tokens already in your wallet, compare MetaMask’s allowance setup. For choosing between spending and borrowing, look at ether.fi’s two modes. Neither is useful if you cannot open the account where you live.

  1. Find where spending permissions can be reduced or revoked.
  2. Check how to move out funds that are not committed to a loan.
  3. Read the card fees separately from on-chain network fees.
  4. Keep your wallet recovery information secure and a backup payment method available.
Details and conditions
  • We have not personally tested either card. This comparison uses their documentation. Keep a backup payment method: wallet ownership does not guarantee uninterrupted card access.
