MoonPay just released an open-source tool called the Open Wallet Standard (OWS), designed for AI agents. This open-source wallet is designed for AI agents that can hold funds, manage assets, and sign blockchain transactions across multiple networks without a human in the loop.
This move addresses a major gap in the current market where agents had trouble managing funds because each system used its own separate wallets and private keys. Fragmented AI wallets are coming to an end, where each wallet managed its own keys and balances separately.
The new standard fixes this by giving all AI agents one simple and safe way to manage funds. Instead of many disconnected accounts, agents can now work from a single pool of money across many blockchains.
How the open wallet standard works
MoonPay’s OWS keeps private keys safe in an encrypted vault on the user’s device. Keys are only unlocked for a very short time when a transaction is signed, then they are immediately deleted from memory. Keys never appear in the agent’s code, logs, or chat with AI models.
OWS works with all major blockchains, making it a very standard tool for developers to build on, and for the AI agents, users can set clear rules, like spending limits, to have transactions in control. Because OWS is open source, developers can readily incorporate and expand upon it. They can leverage the pre-built packages available on GitHub.
This new infrastructure is built on MoonPay Agents, which was launched in February 2026. where the tool already lets AI systems make transactions without a human. Now, with the OWS, it becomes even stronger and more useful.
MoonPay CEO and co-founder Ivan Soto-Wright noted that while the agent economy had payment rails, it lacked a wallet standard, and this release finally completes that infrastructure stack. Security and technical architecture.
OWS was developed with contributions from over 15 major organizations, including PayPal, OKX, Circle, Ripple, and the Ethereum Foundation.
The rise of AI agent economy
The whole crypto landscape is moving to support an economy run by AI agents rather than humans. With MoonPay’s new standard, BitGo launched a protocol allowing AI to manage wallets using natural language, while Coinbase introduced its x402 protocol for automated stablecoin payments. With additional tools from Visa and Stripe-backed Tempo, the industry is united in a single goal, building the financial infrastructure for autonomous AI bots to trade, spend, and earn on a global scale.
