Crypto payments firm MoonPay has open-sourced a new wallet infrastructure standard designed to support autonomous AI agents transacting across blockchains, marking its latest push into AI-native crypto tooling.
MoonPay has introduced the Open Wallet Standard (OWS), an open-source standard that enables AI agents to securely hold assets, sign transactions, and make payments across multiple networks without exposing private keys, according to a statement shared Monday with The Block.
The release — available on GitHub, npm, and PyPI — builds on MoonPay’s earlier rollout of “MoonPay Agents,” a non-custodial software layer launched in February that allows AI systems to interact with wallets and execute transactions programmatically.
“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, CEO and co-founder of MoonPay, said in the statement.
Agent economy
MoonPay said the new standard addresses a missing layer in the emerging “agent economy,” where AI systems increasingly perform tasks such as purchasing data, accessing APIs, or paying for compute services.
By open-sourcing the wallet layer, MoonPay aims to standardize how AI agents manage keys, sign transactions, and interact with different blockchain networks. “The standard is not competing with existing protocols,” the company said. “It makes them more valuable. Any protocol that requires a signed transaction now has a common wallet to call.”
The OWS is designed to act as a universal infrastructure, allowing agents to use a single wallet across protocols and chains. It supports multiple blockchain ecosystems, including Ethereum-compatible networks, Solana, Bitcoin, and others.
A central feature of the standard is its emphasis on secure key management. Private keys are encrypted, and only briefly decrypted to sign transactions before being wiped from memory, according to the statement.
MoonPay noted that more than a dozen organizations — including PayPal, Ripple, Circle, Solana Foundation, and TON Foundation — have contributed to the standard, reflecting broad industry interest in AI-driven financial infrastructure.
