AI agents have taken a significant leap in their capabilities, now able to autonomously trade cryptocurrencies, manage portfolios, and pay for services. However, a critical barrier has been their inability to agree on how to utilize digital wallets—until MoonPay recently introduced a solution.
On March 23, following extensive development, MoonPay launched the Open Wallet Standard (OWS), an open-source framework that provides AI agents with a secure, universal interface to manage funds, sign transactions, and engage with blockchains. This initiative aims to create a shared language for AI agents, eliminating the need for each to forge its own unique method of interacting with wallets. The standard is now available on platforms such as GitHub, npm, and PyPI, receiving support from over 15 organizations, including major players like PayPal, OKX, Ripple, and the Ethereum Foundation.
Historically, the rapid evolution of the “agent economy” has resulted in a chaotic landscape, where AI agents often reinvent essential tools for wallet management. For instance, during the first quarter of 2026 alone, over 340,000 on-chain wallets were controlled by AI agents, but each framework developed its own key management protocols. Consequently, this led to severe fragmentation and security risks, as private keys frequently ended up in unsafe environments like plaintext files—analogous to hiding a house key under a welcome mat.
MoonPay’s foray into this space began with the launch of MoonPay Agents in February 2026, a non-custodial software layer allowing AI to access wallets and transact via command line seamlessly. This product featured compatibility with the x402 protocol and multi-chain support. Despite these advancements, MoonPay identified a core issue: the lack of a standardized method for how AI agents should engage with wallets. Therefore, the company opted to develop and open-source the OWS.
According to Ivan Soto-Wright, CEO and co-founder of MoonPay, “The agent economy has payment rails. It didn’t have a wallet standard. We built one, open-sourced it, and now the full stack exists.”
At its essence, the OWS defines a framework for how AI agents should create wallets, manage keys, sign transactions, and communicate with blockchain networks—all while keeping private keys secure and hidden. This mechanism allows AI agents to authorize transactions without ever directly handling sensitive cryptographic information. The standard’s multi-chain compatibility is critical, accommodating various blockchain networks, enabling agents to conduct transactions across different platforms seamlessly.
The diverse list of contributors to the OWS underscores its potential impact; institutions like PayPal lend traditional financial credibility, while organizations such as the Ethereum Foundation and Solana Foundation reinforce the standard’s relevance to major blockchain ecosystems. Moreover, the inclusion of LayerZero adds cross-chain interoperability, highlighting a concerted industry effort to solidify this initiative.
The timing of the OWS release aligns with the rapid growth of the AI-crypto intersection, projected to expand from a market size of $5.1 billion in 2025 to $55.2 billion by 2035. Some research suggests that AI agents might manage up to 30% of all crypto transactions by 2035, a prospect supported by recent strides like the launch of micropayment platforms specifically designed for AI-to-AI transactions.
From an investment perspective, the introduction of the OWS could significantly impact the landscape. Standardization generally accelerates adoption rates, simplifying the process of creating AI-driven financial products. This shift may pose challenges for companies that have relied on proprietary wallet integrations, while simultaneously offering MoonPay a pathway to establish itself as a foundational layer within the ecosystem.
However, there are also challenges and risks to consider. Recent vulnerabilities in AI-driven smart contracts have resulted in substantial losses, sparking concerns about security in implementations of the OWS. The open-source nature of the framework means anyone can build on it, but not all developers will prioritize security to the same degree as MoonPay and its established partners.
Furthermore, regulatory uncertainty continues to pose a dilemma. Jurisdictions are still trying to define how to classify AI agents for compliance, raising questions about liability and transaction legitimacy, especially when it comes to potential sanctions violations. Additionally, the role of cryptocurrency in the evolving agent economy remains in flux, with traditional payment giants like Visa and Mastercard not remaining idle.
In conclusion, MoonPay’s Open Wallet Standard represents a potentially transformative infrastructure project that, if widely adopted, could underpin the burgeoning AI agent economy. The implications of this framework could significantly expedite the integration of AI agents into economic systems, determining whether the future of automated transactions unfolds over a few years or stretches out longer, while also influencing whether they rely on crypto or traditional banking infrastructures.
