MoonPay's PayBox Empowers Users to Control AI-Initiated Crypto Transactions

MoonPay has introduced PayBox, a payment vault designed to let users authorize AI assistants such as ChatGPT and Claude to carry out crypto actions directly from a conversation. The tool is positioned as a safer way for AI agents to handle tasks like token swaps, cross-chain transfers, and DeFi interactions, while keeping users in control of their funds.

PayBox protects wallet keys using multi-party computation and trusted execution environments to prevent unilateral access by either the AI or MoonPay. It supports multiple chains and payment rails, including debit cards, bank accounts, Apple Pay, and PayPal.

The launch highlights the growing role of x402, an open payments protocol developed by Coinbase for internet-native payments by AI agents. x402 has been moving toward wider industry standardization, including governance under the Linux Foundation and integration across cloud and custody infrastructure.
