MoonPay Introduces PayBox: Streamlining Cryptocurrency Transactions with ChatGPT Integration

MoonPay has introduced PayBox, a noncustodial payment vault that enables users to carry out cryptocurrency transactions and shop online utilizing the features of ChatGPT and Claude.

Revolutionizing AI-Enabled Transactions with MoonPay PayBox

PayBox combines a payment vault with AI technologies such as ChatGPT and Claude, boosting transactional efficiency through user-friendly conversational interfaces. The AI evaluates options, monitors transactions, and executes tasks based on user approval.

This feature allows users to buy digital assets with fiat, swap tokens, transfer assets between blockchains, and interact with decentralized finance platforms. Additionally, PayBox simplifies booking flights, making reservations, and online shopping.

This innovation elevates AI assistants from simple transaction facilitators to proactive agents capable of executing specific tasks for users, all while adhering to the security protocols established within the PayBox account.

MoonPay has announced that PayBox will be available on its platform, requiring users to connect to the relevant AI service via a dedicated connector before initiating payment actions.

Authorization Features: Passkeys and Spending Limits

PayBox provides two authorization options. The “Always Ask” feature mandates user approval for each transaction via a one-time passkey, ensuring that the AI cannot initiate payments without explicit consent.

The “Autonomous” mode allows the connected assistant to act within user-defined spending limits and conditions, eliminating the need for approval for every transaction while ensuring vault security.

Any changes to permission settings or transaction methods require new passkey authorization, enabling users to set spending limits and specify acceptable actions for the assistant before activating autonomous functionalities.

PayBox accommodates both cryptocurrency wallets and payment cards. For wallet transactions, private keys are securely managed using multiparty computation and stored in secure hardware environments. MoonPay assures that neither it nor the connected AI can fully reconstruct the key or independently initiate asset transfers.

For card transactions, the Visa agentic commerce protocol is employed, allowing the assistant to manage authorized purchases without requiring access to or storage of the card number.

Supported Blockchains: Solana and Major EVM Networks

MoonPay has broadened its offerings to include Solana and several Ethereum Virtual Machine-compatible networks, such as Ethereum, Hyperliquid, Tempo, Base, Robinhood Chain, Arbitrum, and Polygon.

The vault adheres to the x402 open payment standard, specifically designed for services that enable AI agent-initiated transactions. MoonPay’s initial x402 integrations focus on streamlining travel bookings, dining reservations, and retail purchases from notable online platforms.

This extensive compatibility facilitates a wide range of coordinated actions, allowing an assistant to help a user in acquiring an asset, transferring it across blockchains, and depositing it into a connected DeFi platform based on account permissions.

The product benefits from advanced security measures implemented by Sodot, a key management firm acquired by MoonPay in 2026. MoonPay emphasizes that Sodot’s infrastructure protects over $50 billion in assets across more than 10 million wallets.

From Institutional Trading to AI Payments: MoonPay’s Vision for the Future

PayBox is a crucial component of MoonPay’s recent initiatives focusing on tokenized financial products. Reports from crypto.news indicate that Franklin Templeton has partnered with MoonPay Trade to link its BENJI tokenized money market fund.

This collaboration allows institutional users to exchange USDC, USDT, and other stablecoins for BENJI through MoonPay’s on-chain trading platform, enhancing liquidity for BENJI holders while improving treasury management, portfolio rebalancing, collateral oversight, and liquidity availability.

PayBox uniquely merges consumer payments and cryptocurrency transactions through conversational AI. MoonPay markets the vault as a noncustodial solution, ensuring users retain control over their assets and preventing both MoonPay and the AI provider from independently executing transactions.

For U.S. users, the integration of Visa’s agentic commerce framework within PayBox may enable AI-assisted card payments, with passkey mechanisms addressing concerns about unauthorized transactions. Access to various cryptocurrency assets, DeFi platforms, and payment services may still be subject to specific geographic and provider-related regulations.
