Key Highlights
- MoonPay introduced the Open Wallet Standard as an open-source solution for AI agent cryptocurrency management.
- The framework delivers a unified, secure interface for handling digital assets across various blockchain networks.
- Over 15 major organizations, including PayPal and Circle, have endorsed the framework.
- The system isolates private key access from AI agent transaction processes.
- MoonPay published the source code with an MIT license across GitHub, npm, and PyPI platforms.
MoonPay unveiled the Open Wallet Standard on March 23, establishing a unified approach for AI agents to interact with cryptocurrency wallets. The organization made the framework publicly available as open-source software under an MIT license. This standard establishes secure protocols for wallet generation, cryptographic key oversight, and transaction authorization across diverse blockchain ecosystems.
Cross-Chain Framework Standardizes AI Agent Wallet Operations
MoonPay distributed the Open Wallet Standard through GitHub, npm, and PyPI repositories. The framework offers AI agents a consistent interface for asset custody and transaction validation. The architecture maintains separation between agents and private cryptographic keys throughout all operations.
According to the company, over 15 industry participants have endorsed this initiative. The supporter roster includes PayPal, OKX, Ripple, Circle, the Ethereum Foundation, and the Solana Foundation. Ivan Soto-Wright, MoonPay’s CEO, stated, “The agent economy has payment rails, and it did not have a wallet standard.”
The framework accommodates EVM-compatible blockchain networks including Ethereum, Base, Polygon, and Arbitrum. Additional supported networks include Solana, Bitcoin, TON, Tron, and Sui. Developers receive full permissions to implement and customize the codebase under the MIT licensing terms.
This framework emerged following MoonPay’s launch of MoonPay Agents in February 2026, which provided AI agents with command-line wallet access. During March, the company added Ledger hardware signing capabilities to its agent infrastructure.
Growing AI Agent Presence on Blockchain Networks
MoonPay documented over 340,000 on-chain wallets controlled by AI agents during the first quarter of 2026. The company observed that numerous agent platforms developed isolated key management approaches. This fragmentation led developers to frequently maintain private keys within environment variables or unencrypted text documents.
The Open Wallet Standard resolves this challenge by decoupling authorization mechanisms from key storage. This architecture allows agents to initiate payment requests while keeping cryptographic secrets isolated. MoonPay emphasized that this design minimizes direct private key exposure.
Several prominent organizations joined as framework contributors. The contributor network spans 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.
Industry projections indicate the AI-crypto sector may expand from $5.1 billion in 2025 to $55.2 billion by 2035. Research forecasts suggest AI agents could process 30% of cryptocurrency transactions by 2035. Shortly before MoonPay’s announcement, Stripe and Tempo introduced their own AI-oriented micropayment solution.
