MoonPay launches PayBox for ChatGPT crypto payments

Jul 31, 2026

MoonPay has launched PayBox, a noncustodial payment vault that lets users prepare and execute crypto transactions or online purchases through ChatGPT and Claude.

MoonPay PayBox turns AI conversations into transactions

PayBox allows users to connect a payment vault to ChatGPT or Anthropic’s Claude and describe a transaction in plain language. The AI assistant can then research available options, prepare the transaction, and execute it under permissions set by the user.

Passkeys and spending rules limit AI access

PayBox offers two authorization models. Under the “Always Ask” setting, every transaction requires the user to approve the action with a passkey. The approval applies to only one transaction and expires after use, preventing the AI from applying it to a different payment.

PayBox supports Solana and major EVM networks

MoonPay has added support for Solana and several Ethereum Virtual Machine-compatible networks. The initial list includes Ethereum, Hyperliquid, Tempo, Base, Robinhood Chain, Arbitrum and Polygon.

MoonPay expands from institutional trading into AI payments

PayBox follows MoonPay’s recent expansion into tokenized financial products. As crypto. news reported in June, Franklin Templeton added its BENJI tokenized money market fund to MoonPay Trade.

For US users, PayBox’s use of Visa’s agentic commerce framework could make AI-assisted card payments more practical, while passkey controls may help address concerns over unauthorized purchases. Access to individual crypto assets, DeFi protocols, and payment services may still depend on location and the rules applied by each provider.
