X’s AI tool Grok now allows users to buy or lend crypto with MoonPay integration

MoonPay has dropped its PayBox wallet and payments tool into Grok, X’s built-in chatbot, giving users a way to buy, lend and move crypto without leaving the conversation. The service is live globally, and MoonPay says it can handle transactions across different blockchain networks.

This is more than a neat demo. MoonPay is clearly betting that the next useful AI assistant won’t just tell you what to do — it’ll prepare the transaction, wait for your passkey approval, and move the money. The company described that flow in plain terms: Grok prepares it, the user approves it, the money moves.

PayBox also plugs into Kamino, the Solana-based lending platform, so users can earn yield on USDC, Circle’s dollar-pegged stablecoin. And the tool isn’t limited to crypto chores. MoonPay says Grok can also help with non-crypto tasks like booking flights or making restaurant reservations.

The timing is telling. MoonPay announced the Grok integration just days after adding a crypto lending feature for eligible users on ChatGPT or Claude. That rollout, however, excludes users in the United States, the United Kingdom, the European Union and Australia. The company has been moving fast: in July it launched a platform for businesses and institutions to trade and move digital assets across more than 200 blockchain networks, and five months before that it released developer tools for AI agents to manage wallets and trade crypto on their own.

X is a natural fit for this kind of experiment, if only because Elon Musk has spent years circling payments, crypto and digital money. But the bigger story is the same one playing out across the industry: Coinbase, Stripe, Circle, Visa and Mastercard are all trying to turn AI agents into something closer to financial actors. The bots are no longer just chatting. They’re getting a checkout line.
