MoonPay Launches PayBox Bringing AI Payments to ChatGPT and Claude

MoonPay has unveiled PayBox, a new payment vault that enables ChatGPT and Claude users to securely send cryptocy, trade digital assets, and even pay for real-world goods and services directly from AI conversations. The platform is designed to give AI assistants the ability to prepare and execute financial transactions without ever taking custody of a user’s funds, marking a major milestone in the emerging field of agentic commerce.

Rather than exposing wallet private keys to artificial intelligence, PayBox uses advanced cryptographic security and user-defined permissions to keep assets under the owner’s control. Users simply describe what they want to do in natural language, approve the transaction with a passkey when required, and the payment is completed through MoonPay’s non-custodial infrastructure.

AI Can Now Execute Real-World Payments

PayBox allows users to connect their crypto wallet directly to ChatGPT or Claude through custom connectors.

Once connected, users can ask their AI assistant to perform actions such as:

• Purchase cryptocy.
• Swap one token for another.
• Bridge assets across blockchains.
• Deposit funds into DeFi protocols.
• Book flights and hotels.
• Pay for everyday goods and services.

The AI prepares the transaction, while the user remains in control of final authorization through secure authentication.

Users Keep Full Control of Their Funds

A key feature of PayBox is that it never gives custody of assets to either MoonPay or the AI assistant.

Instead, the platform uses multi-party computation (MPC) and hardware-secured enclaves to split wallet keys into multiple encrypted pieces. No single party—including MoonPay, ChatGPT, Claude, or the user alone—possesses the complete signing key.

This architecture significantly reduces the risk of theft while ensuring every transaction remains cryptographically secure.

Flexible Permission Controls

PayBox offers two operating modes depending on how much autonomy users want to give their AI assistant.

Users can choose:

• Always Ask, requiring approval with a passkey before every transaction.
• Autonomous Mode, allowing the AI to execute transactions automatically within predefined spending limits and rules.

These controls enable users to automate repetitive financial tasks while maintaining strict limits on what an AI agent can do independently.

Supports Multiple Blockchain Networks

At launch, PayBox supports transactions across several major blockchain ecosystems, including:

• Solana
• Ethereum
• Base
• Arbitrum
• Polygon
• Hyperliquid
• Tempo
• Robinhood Chain

The platform is designed to work across both crypto-native applications and traditional online commerce, giving AI assistants a broader role in managing digital finances.

MoonPay Expands Beyond Crypto Payments

The launch represents another step in MoonPay’s evolution from a fiat-to-crypto payment processor into a broader financial infrastructure provider.

Over the past two years, the company has expanded through acquisitions, stablecoin initiatives, institutional payment products, and AI-focused financial tools. PayBox builds on that strategy by positioning MoonPay at the center of the rapidly growing agentic AI economy, where autonomous software can perform financial tasks on behalf of users while remaining under human oversight.
