MoonPay Launches PayBox: A Payment Vault for AI Agents
MoonPay has launched PayBox, the first payment vault designed to enable secure transactions by AI agents within platforms like Claude or ChatGPT. Users can connect PayBox through a custom connector and allow their AI agent to transact across the open internet without transferring custody of funds. The system allows users to describe financial actions in natural language, with the AI preparing the transaction for user approval via passkey before execution. PayBox supports Solana and EVM-compatible chains such as Ethereum, Hyperliquid, Base, Robinhood Chain, Arbitrum, and Polygon. It leverages threshold cryptography (MPC) and secure enclaves to protect wallet keys, ensuring no single entity can access or sign transactions independently. The product also integrates with x402, an open standard for agent-initiated payments, enabling AI agents to pay services built on that protocol. MoonPay's CEO emphasized the importance of PayBox as a foundational infrastructure for billions of upcoming AI agents needing secure financial capabilities. The platform is designed to close common fraud vectors by splitting wallet keys and using Visa’s agentic commerce protocol.
