Moonpay rolled out PayBox on July 29, a new payment vault designed specifically for AI agents like Claude and ChatGPT. This innovation lets users convert simple language prompts into token trades, travel bookings, or money transfers without handing over control of their funds directly to the AI.
Users interact by typing commands such as converting $100 into PYUSD or swapping tokens for SOL. The AI agent drafts the transaction, but payment only happens after the user approves it with a passkey. This preserves human control, ensuring no transaction is signed or funds moved without explicit consent.
Security Built Into Every Transaction
Moonpay places wallet keys inside secure hardware enclaves and splits keys using multiparty computation, so no single party not Moonpay, not the AI, nor any device has full control over a user’s funds. Payment cards are kept safely, allowing charges through Visa’s agentic commerce protocol without exposing card details to the AI.
Users pick how their AI interacts financially: one mode requires passkey approval for every action, while the other lets AI act autonomously within user-set limits. Permission changes need fresh approvals, and each transaction requires new authorization that can't be reused.
This architecture addresses common fraud routes including stolen credentials, leaked card info, or compromised systems that traditionally could move funds unchecked. By dividing wallet keys and limiting transaction scope, Moonpay ensures a breached phone or stolen passkey won't grant full account access.
The company managing $50 billion in assets behind PayBox is Sodot, powering Moonpay’s secure backend. Next up, Moonpay plans to integrate decentralized finance swaps and perpetual futures trading for AI agents, expanding the vault’s capabilities.
