MoonPay Launches Virtual Debit Card Enabling Stablecoin Spending via AI Agents

MoonPay is launching a virtual debit card that allows users and AI agents to spend stablecoins directly from self-custodied onchain wallets at merchants that accept Mastercard, using real-time crypto-to-fiat conversion at checkout.

The card, developed with Monavate and Exodus Movement, Inc., connects onchain wallets to traditional card rails, enabling transactions without preloading funds or transferring assets offchain, with smart contracts authorizing spending at the point of purchase.

Available through MoonPay's CLI and agent workflows to users in the UK and Latin America, the card is designed for programmatic use, allowing users to delegate spending permissions to AI agents, with identity verification required before issuance, the company said.

The system converts stablecoins to fiat at the moment of purchase while maintaining user custody, with funds accessed only when a transaction is authorized and returned immediately if a payment is declined.

MoonPay, founded in 2019 and based in Miami, is a financial technology company that provides payment infrastructure for moving funds between fiat and digital assets. The card builds on the company's broader push into AI-driven payments infrastructure.

In March, MoonPay released an open-source wallet standard designed to let AI agents hold funds and execute transactions across blockchains from a single wallet.

Payment infrastructure evolves for AI-driven transactions

The launch comes as crypto, technology and payments companies ramp up efforts to build infrastructure for AI-driven transactions. Coinbase introduced its x402 standard for stablecoin payments over HTTP in 2025, enabling applications and AI agents to pay for services programmatically.

Recently, the company updated the protocol to support usage-based pricing, allowing payments to scale with compute demand such as data queries and AI processing.

In March, Tempo, a blockchain backed by payments company Stripe, launched its mainnet alongside a Machine Payments Protocol designed to support agent-driven transactions across payment methods. In a post on X, the project said "agent payments will soon overtake human payments on the internet."

More recently, crypto exchange OKX unveiled a protocol supporting agent-to-agent payments, recurring flows and escrow-based settlements across blockchains, allowing software agents to execute more complex financial transactions without human input.

Elsewhere, non-crypto companies are working to connect AI agents with existing payment systems. Google announced its Agent Payments Protocol in September 2025, designed to support transactions across cards, bank transfers and stablecoins. Visa has also released a command-line tool aimed at enabling programmatic payments by AI agents, allowing developers to initiate transactions directly through code.
