Moonpay has introduced the Open Wallet Standard to give artificial intelligence agents a secure and universal way to manage digital assets across major blockchains.
The framework was officially launched on 23 March 2026 as an open-source solution aimed at reducing fragmentation within the growing agent economy.
The Open Wallet Standard allows AI agents to hold value and sign transactions without directly exposing private keys.
The initiative received support from more than 15 major organisations, including the Ethereum Foundation, Solana Foundation, and Paypal.
The framework is now publicly accessible through platforms such as Github, npm, and PyPI for developers and enterprises.
The system tackles a major issue in machine-to-machine commerce by introducing a unified encrypted vault for digital asset management.
It supports eight blockchain families, including Bitcoin, Ethereum, and Solana, ensuring wide compatibility across ecosystems.
The technology uses policy-based controls and local-first storage to keep AI agents operating within defined spending limits.
This approach ensures that autonomous systems remain secure while still allowing seamless transactions across multiple platforms.
Moonpay highlighted that the solution maintains full compatibility with different AI agent frameworks currently in use.
The company currently serves over 30 million users across 180 countries through its global payment infrastructure.
It also supports more than 500 enterprise partners, reinforcing its position in the digital payments and crypto services sector.
The release follows Moonpay’s recent integration of Ledger hardware signing into its agent ecosystem.
This move strengthens its role as a key infrastructure provider in the emerging autonomous and AI-driven economy.
"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,"
Ivan Soto-Wright said.
