Funding Cards

Add funds to prepaid cards via crypto, linked wallet, or internal balance. Funds are available on the card immediately.

Funding methods

  • Crypto funding — Send USDC (or supported stablecoin) to your ClawdSpend deposit address. Once confirmed, credit is applied to your account balance and can be allocated to cards.
  • Wallet funding — Link a wallet and transfer from your balance to a specific card in one API call or from the dashboard.
  • Internal balance — If you already have a positive balance (e.g. from prior crypto or fiat deposits), use the fund endpoint to move funds from your balance to a card.
