Quick Take
  • Solflare and Mastercard have launched a self-custody debit card for spending USDC on the Solana network.
  • The card allows users to pay directly from their wallet, maintaining control of their assets until the transaction.
  • Integrated with Google Pay and accepted globally, it aims to eliminate traditional crypto card frictions like delays and custodial risk.

Solflare, one of the leading non-custodial wallets on the Solana blockchain with over 4 million users, has officially launched the Solflare Card - a card that allows users to spend USDC instantly anywhere Mastercard is accepted, all while maintaining full self-custody of their assets.

This initiative addresses common issues in the crypto card market, such as custodial risks, transaction delays, and hidden fees. By allowing users to maintain control of their private keys until the point of sale, the card directly connects self-custody crypto ownership with real-world, everyday spending.

Key Features of the Solflare Card:

  • True Self-Custody: Assets stay in your Solflare wallet; private keys are never exposed or transferred.
  • Instant Transactions: Spend USDC directly from your wallet in real-time – no waiting for settlements.
  • Global Acceptance: Usable at over 150 million merchants worldwide where Mastercard is accepted.
  • No Hidden Fees: Transparent pricing with zero surprises.
  • Mobile Wallet Integration: Google Pay available at launch; Apple Pay support coming soon.
  • Enhanced Security: Multi-factor authentication including biometrics, PIN, physical card verification, fraud detection, real-time notifications, and 3DS protection.

The card is powered by a strategic partnership with Mastercard, marking another step in the payment giant's efforts to integrate digital assets into everyday commerce.
