What is a Spend Card?
A spend card (or crypto debit card) enables users to spend cryptocurrency at traditional merchants by automatically converting crypto to fiat at the point of sale — bridging the gap between crypto holdings and everyday spending.
WHY IT MATTERS
Crypto spend cards (from providers like Coinbase Card, Gnosis Pay, and Crypto.com) convert your crypto to fiat in real-time when you tap to pay. You hold USDC in your wallet, swipe the card at a coffee shop, and the merchant receives dollars while your USDC balance decreases.
For AI agents, spend cards represent the bridge between on-chain operations and real-world payments. An agent managing travel bookings might need to pay hotels (accepting cards) while managing a crypto treasury. A spend card enables this without manual fiat conversion.
The programmability of smart wallet-backed spend cards makes them interesting for agents. Gnosis Pay, for example, uses a Safe smart account — meaning you can add spending modules, limits, and controls directly on the card's underlying wallet.
HOW POLICYLAYER USES THIS
PolicyLayer provides card-like spending controls for on-chain agent transactions — per-transaction limits, daily caps, and category restrictions, mirroring the controls traditional spend cards offer but for native crypto operations.
