MoonPay PayBox is a non-custodial payment vault that turns Claude and ChatGPT into autonomous financial agents capable of executing transactions on Solana and other blockchains through conversational prompts.

The introduction of PayBox represents a pivotal advancement in how artificial intelligence interacts with financial systems on blockchain networks. By allowing direct integration with popular AI platforms, MoonPay has created a bridge that enables agents to perform real-world actions based on user instructions given in natural language. This capability transforms static AI conversations into dynamic, actionable processes that can handle economic exchanges on decentralized ledgers like Solana.

This development comes at a time when AI agents are becoming more sophisticated and capable of handling complex tasks. The ability to manage payments without switching applications enhances the utility of these models in practical scenarios involving commerce and finance. Users no longer need to copy details between apps or rely on manual execution for routine operations.

## What background led to the creation of PayBox for AI agents?

Prior to this launch, AI models like Claude and ChatGPT were primarily limited to generating text responses and providing information without the ability to execute transactions independently. MoonPay identified this gap and developed PayBox to fill it with secure payment capabilities that align with the growing demand for agent autonomy in digital environments.

The company had previously acquired Sodot earlier in 2026, which provided the key management infrastructure necessary for building such a product. This acquisition allowed MoonPay to leverage established technology for securing assets on a large scale while maintaining the principles of user control and decentralization.

The open internet presents numerous opportunities for AI agents to engage in economic activities, but security concerns have historically hindered such integrations. PayBox addresses these by using advanced cryptographic methods to maintain user control over funds and approvals at every stage of the process.

## How does the prompt-approve-pay mechanism function in practice?

The flow begins when a user prompts their AI agent in Claude or ChatGPT to perform a transaction, such as booking a reservation or making a purchase. The agent then proposes the action, and the user approves it using a passkey that is scoped to that single action and cannot be reused for other purposes.

Once approved, the payment is executed on the blockchain without the need for the user to leave the chat interface. This seamless process is designed to make financial interactions as natural as sending a message while preserving security through explicit consent mechanisms.

The passkeys are non-reusable, adding an extra layer of security by preventing any potential misuse or replay attacks. This design ensures that each transaction requires explicit consent from the user and aligns with the non-custodial philosophy that keeps control in human hands.

## What blockchains receive support from the PayBox system at launch?

At the time of launch, PayBox includes support for Solana as a primary focus for its speed and low costs in transactions. Additionally, it covers several EVM-compatible chains that are popular in the crypto ecosystem and offer diverse features for different types of agent activities.

The listed chains include Ethereum for its established position, Base and Arbitrum for layer two scaling solutions, Polygon for its enterprise applications, and newer ones like Hyperliquid, Tempo, and Robinhood Chain. More chains are expected to be added over time as the product evolves.

This multi-chain approach allows AI agents to choose the most suitable network for each transaction based on factors like speed, cost, and specific use case requirements. The inclusion of both native and EVM environments broadens the scope of possible operations significantly.

The inclusion of Solana highlights the growing importance of this blockchain in the AI and crypto intersection due to its high throughput capabilities. Transactions on Solana can be completed quickly, which is essential for agent-driven activities that may require real-time responses from the AI model.

EVM compatibility ensures that PayBox can tap into the large ecosystem of decentralized applications and tokens that exist on those networks. This broad support maximizes the potential use cases for the AI agents across various trading and payment scenarios.

## How is security maintained through the non-custodial MPC and TEE architecture?

The non-custodial nature of PayBox means that users retain full control over their funds at all times. The use of multi-party computation and trusted execution environments ensures that private keys are never fully assembled in one place, reducing exposure to potential breaches.

Neither the MoonPay service nor the AI agent itself has access to the complete private key material. This prevents any single point of failure or unauthorized access that could lead to loss of assets and maintains the integrity of the wallet throughout its operation.

The infrastructure from Sodot, which secures more than $50 billion in assets and over 10 million wallets, provides the foundation for this security model. It has been trusted by leading crypto companies for similar purposes in the past.

## What permission settings are available for AI agent autonomy?

Users can choose between Always Ask mode, where a passkey approval is required for every transaction, or Autonomous mode, where the agent can operate within predefined limits set by the user. These options provide flexibility depending on the level of oversight desired.

Even in autonomous mode, any change to the rules or limits necessitates a fresh human passkey approval to maintain security and user oversight. This balances convenience with control and ensures ongoing human involvement in critical decisions.

The scoped nature of the approvals ensures that permissions do not extend beyond the intended transaction, reducing the risk of overreach by the AI agent. Custom connectors facilitate the initial setup between the wallet and the chosen AI platform.

## What are the market and stakeholder implications of this AI payment integration?

For the AI industry, this integration opens up new avenues for agents to participate in economic activities, potentially leading to more advanced autonomous systems in e-commerce and finance. Stakeholders in crypto may see increased adoption as AI drives transaction volume on supported networks.

MoonPay positions itself as a key player in the emerging space of AI-native financial tools. The launch could attract partnerships with other AI providers and blockchain projects looking to enable similar capabilities for their users and developers.

Retail users benefit from the simplicity of managing finances through conversation, while businesses may explore using AI agents for automated payments in supply chains or customer service scenarios. The x402 standard supports initial applications in reservations, travel, and retail shopping.
