MoonPay has introduced a virtual debit card that enables both users and artificial intelligence agents to spend stablecoins directly from self-custodied onchain wallets at any merchant that accepts Mastercard. The card leverages real-time crypto-to-fiat conversion at the point of checkout, eliminating the need to preload funds or move assets offchain.
How the card works
Developed in partnership with Monavate and Exodus Movement, Inc., the card connects self-custodied wallets to traditional Mastercard payment rails. Smart contracts authorize spending at the exact moment of purchase, converting stablecoins to fiat while maintaining user custody. If a payment is declined, funds are returned immediately to the wallet. The card is available through MoonPay’s command-line interface and agent workflows to users in the UK and Latin America, with identity verification required before issuance.

Designed for programmatic use
MoonPay said the card is built for programmatic applications, allowing users to delegate spending permissions to AI agents. This marks a shift from traditional card models, where funds must be preloaded onto a custodial account. Instead, the new system keeps assets under user control until a transaction is authorized. MoonPay, founded in 2019 and headquartered in Miami, is a financial technology company specializing in payment infrastructure between fiat and digital assets.
Broader push into AI-driven payments
The launch builds on MoonPay’s broader strategy to develop infrastructure for autonomous transactions. In March, the company released an open-source wallet standard designed to let AI agents hold funds and execute transactions across multiple blockchains from a single wallet. The move reflects a growing industry trend toward enabling software agents to conduct financial activities without human intervention.

Industry context: payment infrastructure for AI agents
MoonPay’s announcement arrives amid a wave of similar initiatives across the crypto, technology, and payments sectors. Coinbase introduced its x402 standard for stablecoin payments over HTTP in 2025, enabling AI agents to pay for services programmatically. In March, the company updated the protocol to support usage-based pricing, allowing payments to scale with compute demand such as data queries and AI processing.
Also in March, Tempo, a blockchain backed by payments company Stripe, launched its mainnet alongside a Machine Payments Protocol designed for agent-driven transactions. The project stated on X that “agent payments will soon overtake human payments on the internet.” More recently, OKX unveiled a protocol supporting agent-to-agent payments, recurring flows, and escrow-based settlements across blockchains.
Outside the crypto sector, Google announced its Agent Payments Protocol in September 2025, designed to support transactions across cards, bank transfers, and stablecoins. Visa also released a command-line tool enabling programmatic payments by AI agents, allowing developers to initiate transactions directly through code.
Why this matters
The development of payment rails that allow AI agents to spend digital assets autonomously represents a significant evolution in both crypto and traditional finance. For users, it means greater flexibility in how they manage and deploy funds. For businesses and developers, it opens the door to automated, trust-minimized transactions that could reshape e-commerce, subscription services, and decentralized finance. However, questions remain about security, regulatory compliance, and the potential for misuse, particularly as autonomous agents gain greater financial autonomy.
Conclusion
MoonPay’s virtual debit card is a concrete step toward integrating self-custodied crypto wallets with mainstream payment networks, specifically designed for the emerging era of AI-driven transactions. As major players from Coinbase to Google build competing infrastructure, the race to define how autonomous agents pay for goods and services is accelerating. The long-term impact on consumer finance, business operations, and digital asset adoption will depend on how these systems balance convenience, security, and regulatory oversight.
