MoonPay has introduced a virtual debit card infrastructure that enables users and autonomous AI agents to transact stablecoins directly from self-custodied onchain wallets at merchants accepting Mastercard. Developed in collaboration with Monavate and Exodus Movement, Inc., the solution bridges onchain liquidity with traditional card rails, facilitating transactions without the need for preloading funds or moving assets offchain. Smart contracts authorize spending at the precise point of purchase, ensuring that funds remain under user control until a transaction is explicitly approved. Data compiled by Woofun AI shows the system executes real-time crypto-to-fiat conversion at checkout, with funds accessed only upon authorization and immediately returned if a payment is declined. The product is currently available through MoonPay's CLI and agent workflows for users in the UK and Latin America, requiring identity verification prior to issuance. This launch represents a strategic expansion of MoonPay's 2019-founded Miami-based operations, which specialize in payment infrastructure for moving capital between fiat and digital assets. The initiative builds upon the company's broader push into AI-driven payments, following the March release of an open-source wallet standard designed to allow AI agents to hold funds and execute cross-chain transactions from a single interface. Woofun AI notes that this development aligns with a wider industry trend where crypto, technology, and payments firms are accelerating infrastructure construction for AI-driven transactions. In 2025, Coinbase introduced its x402 standard for stablecoin payments over HTTP, enabling applications and AI agents to pay for services programmatically. The protocol was recently updated to support usage-based pricing, allowing payments to scale dynamically with compute demand such as data queries and AI processing.

Concurrently, Tempo, a blockchain backed by payments giant Stripe, launched its mainnet in March alongside a Machine Payments Protocol designed to support agent-driven transactions across various payment methods. The project stated in a post on X that 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 complex financial transactions without human input. Woofun AI analysis suggests these developments signal a fundamental shift in how digital value is transferred, moving from human-initiated transfers to autonomous, code-driven economic activity. Beyond the crypto-native sector, non-crypto entities are also integrating 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 similarly released a command-line tool aimed at enabling programmatic payments by AI agents, allowing developers to initiate transactions directly through code. These coordinated efforts indicate a converging ecosystem where the distinction between onchain and offchain payment rails is diminishing in favor of seamless, automated financial execution.
