MoonPay has expanded PayBox, its payment vault designed for AI agents, to Grok, allowing users to connect self custodial wallets, payment cards and other credentials to the AI assistant.
The integration allows Grok users to request transactions using natural language, including buying stablecoins, swapping tokens, bridging assets, interacting with decentralized finance protocols and making purchases.
Grok prepares the transaction before the user approves it through a passkey.
PayBox initially launched in July with support for ChatGPT and Claude. The addition of Grok expands the product to another major AI platform as companies develop assistants capable of executing actions on behalf of users rather than only providing information.
MoonPay said PayBox can connect Grok with platforms across the open internet for token trading, asset bridging, DeFi and payments. The system also supports x402, an open payment standard designed to allow AI agents to pay services that accept agent initiated transactions.
