MoonPay launched PayBox, a payment vault that integrates directly into Claude and ChatGPT and allows AI agents to execute transactions autonomously. Wallet keys are protected by MPC and TEE cryptography, meaning no single party, neither MoonPay nor the AI itself, can access funds or sign transactions alone. The infrastructure comes from Sodot, an Israeli key management firm acquired for roughly $100 million in April, whose technology already secures over $50 billion in assets and 10 million wallets. PayBox supports Solana and seven Ethereum-compatible chains at launch, along with Coinbase’s x402 open payment protocol. First integrations include restaurant reservations, flight bookings, and shopping across major online retailers.
