MoonPay has launched a new stablecoin debit card on Mastercard’s network that lets AI agents spend crypto like regular money at physical and online stores. The card connects to stablecoin balances and converts them to local currency at the moment of purchase, so merchants still receive fiat and do not need crypto tools. Mastercard says the product works across more than 150 million locations where its cards are accepted worldwide.
The new card builds on MoonPay Agents, a non-custodial software layer that gives AI agents access to wallets, funds, and onchain transactions. Once a human user completes identity checks and funds a wallet, an AI agent can trade, swap tokens, and now route spending through the Mastercard-branded card. MoonPay’s CEO Ivan Soto-Wright describes the company as a bridge between AI and money, arguing that crypto rails are the fastest way for software agents to move value.
How the Stablecoin Card Works with AI Agents
MoonPay uses Iron, a stablecoin payments platform it acquired, to power the debit card and deepen its infrastructure for everyday spending. The card converts stablecoins to fiat during each transaction, so buyers see a normal card payment while value moves over crypto rails in the background. This design aims to keep cardholder flows simple, while giving developers access to programmable money through MoonPay’s APIs and command-line tools.
For AI agents, the card extends an existing toolkit that already covers wallet creation, funding, recurring purchases, cross-chain swaps, and off-ramping back to fiat. Agents can manage a user’s non-custodial wallet on their device, follow preset rules, and trigger card-based payments when services or subscriptions are due. According to MoonPay, human users still set permissions and complete Know Your Customer checks once, but agents can operate within those limits without further manual approval.
Why Mastercard is Backing Stablecoin Cards
Mastercard is working with MoonPay to bring stablecoin payments into mainstream finance, with a focus on security, compliance, and fraud checks. Its network tools help screen transactions and link crypto services with banks and fintechs, creating a bridge between crypto and traditional finance.
For MoonPay, the new card strengthens its role in “agentic payments,” where software systems make and manage payments for users. The company says AI agents will need direct access to money, not just data, to handle tasks like subscriptions, trading strategies, and other ongoing services.
