On March 23, 2026, Moonpay unveiled and open-sourced the Open Wallet Standard (OWS), an open-source framework designed to overcome fragmentation in the agent economy by enabling artificial intelligence agents to hold value and sign transactions across multiple blockchains without exposing private keys.
Industry Giants Unite Behind OWS
The standard has received backing from over 15 major organizations, including the Ethereum Foundation, Solana Foundation, Paypal, Ripple, and OKX. OWS is now publicly available on GitHub, npm, and PyPI, allowing developers globally to integrate it into their projects.
Technical Core: Unified Encrypted Vault and Policy-Gated Signing
OWS provides a unified encrypted vault that supports eight blockchain families, including Bitcoin, Ethereum, and Solana. Its core innovations include policy-gated signing and local-first storage. These features ensure autonomous agents operate within human-defined spending limits while private keys remain encrypted at rest and are never exposed to the agent or large language model (LLM). This design addresses critical security and compliance needs in machine-to-machine commerce.
Moonpay's Agent Ecosystem Expansion
Moonpay previously introduced Moonpay Agents, a non-custodial software layer enabling AI agents to autonomously manage wallets and execute onchain transactions. With the launch of OWS, Moonpay completes the technology stack of “payment rails + wallet standard.” Ivan Soto-Wright, CEO and co-founder of Moonpay, stated: “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.”
Moonpay now serves more than 30 million customers across 180 countries and partners with over 500 enterprises. The company recently integrated Ledger hardware signing into its agent stack, further solidifying its role as a primary infrastructure provider for the emerging autonomous economy.
The open-source release of OWS marks a significant milestone in the convergence of AI and crypto payments, offering a trustworthy foundation for value transfer among next-generation autonomous agents.
