Wallets for AI Agents: MoonPay Launches Open Cross-Chain Wallet Standard

The rise of autonomous AI agents is reshaping the crypto landscape, and infrastructure is racing to keep up. Enter MoonPay, which has unveiled the Open Wallet Standard (OWS), a breakthrough designed to power wallets for AI agents across multiple blockchains securely and efficiently.

Announced in late March 2026, this innovation addresses a critical gap: while AI agents can already transact and interact with blockchain systems, there has been no universal standard defining how they should securely manage wallets. 

With OWS, MoonPay introduces a scalable, open-source framework that could become foundational to the emerging “agent economy.”

Key Takeaways

• OWS introduces a secure, open-source wallet standard tailored specifically for AI agents.

• It enables cross-chain functionality with a single seed phrase across multiple blockchain ecosystems.

• The system ensures zero private key exposure, significantly improving security for autonomous operations.

What Is MoonPay AI Agents Wallet?

The MoonPay AI Agents wallet is built on the Open Wallet Standard (OWS), an MIT-licensed specification that defines how AI agents create, manage, and use crypto wallets.

Unlike traditional wallets, OWS is purpose-built for machine-driven environments. It ensures that AI agents can perform transactions, manage funds, and interact with decentralized systems without ever accessing or exposing sensitive private keys.

This standard builds upon MoonPay’s earlier “MoonPay Agents” infrastructure, which already allowed AI systems to execute blockchain actions programmatically. OWS now completes the stack by introducing a universal wallet framework.

How the Open Wallet Standard (OWS) Works

OWS is designed as a modular and flexible system composed of seven core components:

1. Wallet Storage and Key Management

Defines how keys are securely stored and derived, ensuring consistency across implementations.

2. Transaction Signing

Standardizes how transactions are signed without exposing private keys to AI agents or applications.

3. Policy Engine

Before any transaction occurs, predefined rules such as spending limits or contract restrictions are enforced.

4. Agent Access Control

Determines how AI agents interact with wallets while maintaining strict boundaries.

5. Key Isolation

Ensures private keys are never accessible to AI models or external processes.

6. Wallet Lifecycle

Manages wallet creation, usage, and termination in a standardized way.

7. Supported Chains

Provides interoperability across multiple blockchain ecosystems.

This modular approach allows developers to adopt only the components they need while maintaining compatibility with the broader ecosystem.

Key Features of MoonPay AI Agent Wallet

Zero Key Exposure Security

Private keys are encrypted and only briefly decrypted in protected memory for transaction signing then immediately erased. This eliminates the risk of key leakage to AI models or external systems.

Cross-Chain with One Seed Phrase

A single seed phrase can generate wallets across multiple blockchain networks, removing fragmentation and simplifying operations.

Pre-Signing Policy Controls

Operators can define strict rules, such as:

• Spending caps

• Approved smart contracts

• Time-based permissions

This ensures AI agents operate within safe, predefined boundaries.

Developer-Friendly Ecosystem

OWS supports:

• Node.js and Python SDKs

• CLI tools

• Integration with AI frameworks like ChatGPT and LangChain

Hardware Wallet Integration

Support for Ledger devices adds an additional layer of security for high-value operations.

Supported Blockchains

OWS enables true cross-chain functionality, supporting major ecosystems including:

• EVM-compatible chains (like Ethereum, Base, Polygon)

• Solana

• Bitcoin

• Cosmos

• Tron

• TON

• Filecoin

• XRP Ledger

This unified approach allows AI agents to seamlessly operate across chains without managing separate wallets.

Industry Backing and Partnerships

The Open Wallet Standard is not a solo effort. It has been developed with contributions from major organizations, including:

• PayPal

• OKX

• Ripple

• Circle

• Ethereum Foundation

• Solana Foundation

This broad collaboration gives OWS strong credibility and positions it as a potential industry-wide standard.

Use Cases of Wallets for AI Agents

OWS unlocks a wide range of real-world applications:

Autonomous Trading

AI agents can execute trades and rebalance portfolios across multiple chains without manual intervention.

AI-to-AI Payments

Agents can pay each other for services such as data, compute power, or APIs.

Cross-Chain Transactions

An agent can purchase services on one blockchain and settle payments on another instantly.

Subscription and Micropayments

AI agents can manage recurring payments or microtransactions within predefined limits.

Why MoonPay AI Agent Wallet Matters

The launch of OWS marks a pivotal moment in the evolution of AI-driven crypto systems. As the agent economy grows, the need for standardized, secure wallet infrastructure becomes critical.

By introducing a universal framework, MoonPay eliminates fragmentation, enhances security, and accelerates innovation. The standard complements existing payment protocols rather than competing with them, acting as the secure execution layer for transactions.

With projections suggesting massive growth in AI-crypto integration over the next decade, OWS could become the default wallet layer similar to how operating systems standardized mobile ecosystems.

Conclusion

MoonPay’s Open Wallet Standard is more than just a technical upgrade—it is foundational infrastructure for the future of AI in crypto.

By combining cross-chain functionality, strict security controls, and open-source accessibility, OWS enables AI agents to operate autonomously without compromising safety. As adoption grows and more developers integrate the standard, it could redefine how digital assets are managed in an AI-driven world.

Before engaging with emerging technologies like AI agent wallets, always conduct thorough research and explore trusted platforms such as Bitrue to stay informed.
