MoonPay has added Solana lending protocol Kamino to its PayBox product, allowing eligible users to lend assets or borrow against collateral through conversations with ChatGPT or Claude. The integration announced on August 27 extends PayBox beyond payments, swaps and bridging into collateralized decentralized finance.
AI instructions replace the usual lending interface
Users can instruct the AI interface to supply tokens to Kamino in pursuit of yield or borrow USDC against collateral already placed in the protocol. The integration does not create a new loan product. Instead, it provides a conversational route into Kamino’s existing markets and transaction flow.
MoonPay said users can require passkey approval for every transaction or permit the AI agent to operate within preset limits. That control structure is important because the software is acting on positions that can change in value after execution. The rollout follows MoonPay’s earlier expansion of crypto access in the United States, including its Cash App Pay integration.
Collateral risk remains with the user
A natural-language interface does not remove the mechanics or risks of DeFi lending. If collateral falls below Kamino’s required threshold, liquidators may repay the debt and take part of the collateral. Execution errors are another concern when an AI system is allowed to submit transactions involving user funds.
PayBox therefore sits at a more consequential point in the agentic-crypto stack than small automated payments. An instruction can open or adjust a leveraged position that may require continued monitoring. Similar efforts to give software agents controlled access to blockchain services are also appearing outside Solana, including Algorand’s AC2 communication framework.
Access is geographically restricted
MoonPay introduced PayBox in July with payments, token swaps, bridging and access to Aave-based yield. Adding Kamino gives the product a direct connection to a major Solana lending venue, but availability is limited.
The company said the integration is unavailable in the United States, United Kingdom, European Union and Australia. Access can also vary by asset and jurisdiction. MoonPay has not disclosed a timetable for expanding eligibility, leaving the immediate rollout focused on markets where the product is currently permitted. The restricted launch also means PayBox’s lending adoption cannot yet be treated as evidence of broad retail demand across MoonPay’s full customer base.
