MetaMask Card has achieved a unique position as the only self-custodial debit card that supports the Base network.​

Users can now:

  • Fund their card with USDC or USDT on Base
  • Tap to pay anywhere Mastercard is accepted
  • Maintain full custody of their funds

This integration allows real-world spending of Base network tokens while preserving the self-custodial principles that distinguish MetaMask from traditional payment solutions.​

The card bridges the gap between DeFi holdings and everyday purchases, enabling users to spend their Base-based stablecoins directly without converting to fiat first.​
