MoonPay Introduces PayBox for AI-authorized Crypto Transactions

MoonPay has introduced PayBox, a payment vault that enables users of ChatGPT and Claude to authorize AI transactions without compromising their control over funds. The feature allows users to connect a crypto wallet and payment methods, preparing transactions such as token swaps, crosschain transfers, and DeFi interactions using natural-language prompts.

Users can approve each transaction with a passkey or set spending limits that allow the AI to execute certain actions automatically. PayBox uses multi-party computation and trusted execution environments to protect wallet keys, preventing either the AI assistant or MoonPay from independently accessing user funds.

The platform also lets users require approval for every transaction or allow AI to act autonomously within predefined spending and permission limits. PayBox supports multiple blockchains and payment methods, including debit cards, bank accounts, Apple Pay, and PayPal.
