MoonPay Launches PayBox: AI-Powered Crypto Payments for ChatGPT and Claude
MoonPay has launched PayBox, an AI-powered payment vault that allows users of ChatGPT and Claude to complete crypto transactions through a normal conversation while staying in control of their money.
The platform enables users to buy crypto, swap tokens, move assets between blockchains, and use decentralized finance without leaving the chat. To initiate a transaction, users simply need to type a simple request in plain language, and the AI assistant will prepare the transaction for approval.
MoonPay has implemented advanced security measures to protect user funds, including multi-party computation (MPC) and trusted execution environments (TEEs), which divide and store wallet keys across secure hardware environments. This means neither MoonPay nor the AI assistant can access the full key or move a user's funds by themselves.
The company has also integrated PayBox with x402, an open payment protocol that enables AI agents to make internet-native payments. The protocol was contributed to the Linux Foundation in April 2026 and is now managed as an open, vendor-neutral industry standard.
