MoonPay launches open-source cross-chain wallet for AI agents

• MoonPay has launched the Open Wallet Standard (OWS), an open-source infrastructure designed for autonomous AI agents to manage assets and execute transactions.
• The initiative is supported by major industry players including PayPal, Ripple, Circle, and the Solana Foundation.
• The standard enables secure cross-chain payments without exposing private keys, building upon the MoonPay Agents software layer released in February.

Standardizing the AI Agent Economy

Crypto payments firm MoonPay has introduced a new wallet framework specifically tailored for the growing "agent economy." The Open Wallet Standard (OWS) aims to provide a unified way for AI systems to interact with blockchain networks, allowing them to perform tasks such as purchasing data, accessing APIs, and paying for compute resources autonomously. By open-sourcing the protocol on GitHub, npm, and PyPI, MoonPay intends to create a common language for any protocol requiring signed transactions from an automated agent.

According to Ivan Soto-Wright, CEO and co-founder of MoonPay, while payment rails for AI already existed, a standardized wallet layer was the missing piece of the stack. The OWS is designed to fill this gap, making existing protocols more valuable by providing a universal wallet interface they can call upon.

Technical Features and Security

The OWS is built to be chain-agnostic, supporting a wide range of ecosystems including Bitcoin, Solana, and Ethereum-compatible networks. A primary focus of the development is security, particularly the management of sensitive cryptographic keys. To prevent unauthorized access, private keys are kept encrypted and are only decrypted briefly to sign specific transactions. Immediately after the signature is generated, the keys are wiped from memory to minimize the risk of exposure.

Key technical aspects of the release include:

• Full cross-chain compatibility for diverse asset management.
• Integration with the MoonPay Agents non-custodial software layer.
• Availability across major developer repositories for immediate adoption.

Broad Industry Collaboration

The development of the Open Wallet Standard reflects a significant collaborative effort within the cryptocurrency industry. More than a dozen organizations contributed to the project, highlighting the shared interest in AI-driven financial infrastructure. Notable contributors include:

• Financial giants PayPal and Ripple.
• Stablecoin issuer Circle.
• Protocol organizations such as the Solana Foundation and the TON Foundation.

By establishing this standard, MoonPay and its partners aim to ensure that as AI agents become more prevalent in the digital economy, they have a secure, interoperable, and standardized method for handling financial value across the decentralized web.
