MoonPay has introduced PayBox, a payment vault designed to let users of AI chat platforms ChatGPT and Claude authorize cryptocurrency transactions through natural-language prompts while maintaining control over their funds. By connecting their crypto wallets and payment methods to these AI tools, users can instruct the AI to prepare operations such as token swaps, cross-chain asset transfers, and DeFi interactions. Each transaction can be approved manually via a passkey, or users can set spending limits permitting the AI to carry out certain actions automatically.
According to MoonPay, PayBox employs multi-party computation and trusted execution environments to securely protect wallet keys, preventing either the AI assistants or MoonPay from accessing user funds independently. The service supports multiple blockchains and payment methods such as debit cards, bank accounts, Apple Pay, and PayPal. Additionally, MoonPay offers a software development kit enabling third-party developers to integrate PayBox into other AI applications.
PayBox also supports the x402 open payment protocol, originally developed by Coinbase and contributed to the Linux Foundation in April 2026, which facilitates internet-native payments by AI agents. The x402 ecosystem has been expanding, with Coinbase launching tools this year allowing AI agents to accept USDC payments, trade cryptocurrency, and efficiently process micropayments. Major tech firms like Amazon Web Services and Fireblocks have integrated x402-compatible payment solutions, further advancing the protocol’s adoption.
Blockchain analytics firm Chainalysis reported in early June that agentic payments on Coinbase’s Base network using x402 surpassed 100 million transactions within roughly nine months, suggesting significant growth driven partly by speculative applications. At the time of reporting, x402’s public dashboard indicated over 12.7 million transactions in the past 30 days. MoonPay's PayBox integration with x402 aims to enhance secure and user-controlled crypto interactions within AI chat environments, signaling evolving uses of blockchain technology in AI-driven financial services.
