MoonPay Launches PayBox for AI Transaction Management
MoonPay has introduced PayBox, a new payment vault designed to integrate seamlessly with AI agents like Claude and ChatGPT, enabling them to autonomously conduct transactions on behalf of users.
This innovative service acts as a secure digital wallet for both cryptocurrencies and payment cards. Users can instruct the AI chatbot to handle purchases, which are processed after user approval via a secure digital passkey, similar to Face ID.
MoonPay CEO Ivan Soto-Wright highlighted the evolution of financial transactions, stating, "The card hid the cash. The phone hid the card. This is the era where money disappears into conversation." He noted the necessity for secure financial management as billions of AI agents emerge.
Previously, AI assistants could only provide insights and help users plan purchases, but PayBox allows for direct transactions. Currently, it supports restaurant bookings, flight reservations, and shopping with major online retailers, along with token exchanges and decentralized finance (DeFi) investments.
PayBox is compatible with multiple blockchain platforms, including Solana and seven Ethereum-compatible chains, and utilizes the x402 open payment protocol developed by Coinbase, which allows AI agents to facilitate payments across various services.
The development of PayBox has been a priority for MoonPay throughout 2026, following earlier initiatives like an open wallet standard for AI and an application for purchasing cryptocurrency within ChatGPT. The technology powering PayBox comes from Sodot, an Israeli key management startup acquired by MoonPay for around $100 million in April. This technology safeguards over $50 billion in assets and employs multi-party computation (MPC) to secure wallet keys, ensuring that no single entity can access funds independently.
Payments are processed through Visa's agentic commerce protocol, which enhances security by preventing AI from accessing users' card numbers directly. MoonPay asserts that PayBox addresses the tradeoff between convenience and control found in traditional payment solutions, ensuring that neither the platform nor the AI can unilaterally access users' funds.
