MoonPay Unveils Open Source Wallet Standard Allowing AI Agents to Execute Crypto Transactions Globally

MoonPay has taken a major step in bridging the gap between artificial intelligence and cryptocurrency by releasing an open-source wallet standard.

This new framework allows AI agents to hold funds and execute transactions across multiple blockchains, solving a problem that has long hampered autonomous software: fragmented wallet management.

A Unified Approach to AI Wallets

Traditionally, AI systems interacting with crypto had to juggle multiple accounts and keys, creating complexity and inefficiency.

MoonPay’s standard changes this by enabling agents to operate from a single pool of funds.

AI tools can now communicate with other agents and humans, send and receive money, and interact with the internet using standard APIs, according to researchers at MIT Sloan.

The system stores private keys in an encrypted local vault and signs transactions in an isolated environment, keeping sensitive data secure.

Policy controls allow users to predefine spending limits and restrictions before transactions occur, ensuring both autonomy and safety.

Open Source and Modular for Developers

The MoonPay wallet standard is open-source and modular, covering storage, signing, policy controls, and blockchain compatibility.

Developers can access the specification through GitHub, npm, and PyPI, encouraging collaboration across the crypto ecosystem.

Founded in 2019, MoonPay provides infrastructure for moving funds between fiat and digital currencies, offering trading, on- and off-ramps, and crypto payments worldwide.

AI-Driven Crypto Infrastructure Expands

MoonPay isn’t alone in enabling AI-powered crypto functionality.

On Monday, BitGo announced its Model Context Protocol (MCP) server, allowing AI tools to access wallet functions, transaction flows, and staking systems using natural language.

This integration connects BitGo’s infrastructure with AI development environments, letting agents like ChatGPT retrieve documentation, APIs, and product information within workflows.

Other industry initiatives include Coinbase’s x402 protocol for stablecoin transfers via APIs, and Visa and Stripe-backed Tempo’s tools that enable AI systems to programmatically initiate payments.

The push signals a wider trend: making AI active economic participants in decentralized finance and digital payment systems.

Impact and Consequences

This development could fundamentally change how AI interacts with finance.

By allowing AI agents to manage wallets securely and autonomously, the standard may accelerate adoption of machine-driven transactions in business and consumer markets.

At the same time, regulators and security experts may face new challenges in monitoring AI-controlled financial activity.

What’s Next?

Developers and companies are likely to build on MoonPay’s standard, expanding integration with AI-native tools and financial services.

Expect collaborations with major fintech and blockchain players, as well as new AI-first applications for payments, staking, and multi-chain asset management.

Summary

MoonPay’s open-source wallet standard marks a milestone in AI and crypto convergence.

By unifying wallet management, securing private keys, and enabling autonomous transactions, it paves the way for AI agents to operate as independent economic actors.

The broader ecosystem is quickly responding, with BitGo, Coinbase, and others rolling out complementary tools.
