Key Highlights
- MoonPay introduced an open-source framework called the Open Wallet Standard designed specifically for AI agent wallet management.
- The protocol establishes a unified, secure interface for handling cryptocurrency across numerous blockchain networks.
- Over 15 major organizations, including PayPal and Circle, have endorsed the project.
- The system architecture keeps private keys separate from AI agents during transaction processes.
- MoonPay made the codebase publicly available through GitHub, npm, and PyPI under MIT licensing.
On March 23, MoonPay unveiled its Open Wallet Standard, establishing a unified approach for AI agents interacting with cryptocurrency wallets. The payment infrastructure company made the framework available as an open-source solution with MIT licensing. This protocol establishes standardized procedures for wallet generation, cryptographic key oversight, and transaction authorization spanning various blockchain ecosystems.
Cross-Chain Wallet Protocol Targets AI Agent Infrastructure
MoonPay distributed the Open Wallet Standard through GitHub, npm, and PyPI repositories. The framework delivers a consistent interface allowing AI agents to store assets and execute transactions. Crucially, the architecture ensures agents never gain direct access to private cryptographic keys throughout their operations.
According to the company, over 15 industry organizations have thrown their support behind this initiative. The roster of backers features PayPal, OKX, Ripple, Circle, the Ethereum Foundation, and the Solana Foundation. Ivan Soto-Wright, CEO of MoonPay, remarked, “The agent economy has payment rails, and it did not have a wallet standard.”
The protocol accommodates EVM-compatible blockchain networks including Ethereum, Base, Polygon, and Arbitrum. Network compatibility extends to Solana, Bitcoin, TON, Tron, and Sui infrastructures. MoonPay emphasized that developers retain full rights to implement and adapt the code under MIT license terms.
This framework emerged following MoonPay’s February 2026 launch of MoonPay Agents, which provided AI systems with wallet access via command-line tools. In early March, the company incorporated Ledger hardware signature functionality into its agent technology stack.
Growing AI Agent Presence Drives Wallet Security Concerns
During the first quarter of 2026, MoonPay documented over 340,000 blockchain wallets controlled by AI agents. The company observed that numerous agent frameworks developed isolated key management approaches. This fragmentation frequently resulted in developers storing private keys within environment variables or unencrypted text files.
The Open Wallet Standard resolves this vulnerability by decoupling authorization functions from key storage. Within this architecture, an agent can initiate payment requests without possessing the underlying cryptographic material. MoonPay emphasized that this design minimizes direct private key exposure.
Numerous industry stakeholders joined as framework contributors. The contributor roster encompasses Circle, the Ethereum Foundation, the Solana Foundation, the TON Foundation, and the Filecoin Foundation. Additional supporters include LayerZero, Virtuals, Dynamic, Allium, Dflow, Uniblock, and Simmer. Markets has also backed the effort.
Market analysis projects the AI-cryptocurrency sector expanding from $5.1B in 2025 to $55.2B by 2035. Industry research indicates AI agents could process 30% of all cryptocurrency transactions by 2035. Just days prior to MoonPay’s announcement, Stripe and Tempo introduced an AI-oriented micropayment infrastructure.
