Can ChatGPT spend your crypto? MoonPay’s AI payment vault says yes
Most people still think of AI assistants as tools that help you find things — not buy them. MoonPay just moved to change that. The company has launched PayBox, a new AI payment vault that lets users connect their crypto wallets and payment cards directly to ChatGPT and Claude, enabling purchases to happen inside a conversation without handing over control of their funds to anyone.
Key takeaways
- MoonPay’s PayBox is a non-custodial AI payment vault integrating with ChatGPT and Claude via a custom connector for in-conversation transactions.
- Users choose between “Always Ask” mode (passkey approval per transaction) or “Autonomous” mode (AI acts within user-defined spending limits).
- Wallet keys are protected using multi-party computation (MPC) and trusted execution environments (TEEs), so no single party — including MoonPay — holds a complete private key.
- PayBox supports Solana and seven EVM-compatible blockchains, with DeFi features including token swaps and perpetual futures trading planned within the next month.
- The x402 payment standard, originally developed by Coinbase and now governed by the Linux Foundation, underpins PayBox’s cross-service transaction capability.
