MoonPay launches AI stablecoin card on Mastercard

MoonPay has launched a virtual debit card enabling users and AI agents to spend stablecoins directly from self-custodied wallets via Mastercard.

The card allows real-time crypto-to-fiat conversion at checkout, eliminating the need to preload funds or move assets offchain before making payments.

Developed with Monavate and Exodus Movement, the system uses smart contracts to authorise transactions only at the point of purchase.

The product is initially available in the UK and Latin America and is designed for programmatic use, allowing users to delegate spending permissions to AI agents after identity verification.

Funds remain in user custody until a transaction is approved, with any declined payments immediately reversing access to the assets.

The launch builds on MoonPay’s broader push into AI-enabled payments, following its release of a wallet standard that allows AI agents to hold and transact funds across blockchains.

The move comes amid growing competition, with firms including Coinbase, Visa and Google developing infrastructure to support autonomous, agent-driven financial transactions.
