MoonPay unveils open-source standard for AI agent cryptocurrency wallets
MoonPay has introduced an open-source standard for cryptocurrency wallets that enables autonomous AI agents to manage digital assets and conduct cross-blockchain transactions, as organizations develop infrastructure to support machine-driven cryptocurrency payment systems.
MoonPay has unveiled an open-source standard for cryptocurrency wallets that enables autonomous AI agents to manage digital assets and conduct cross-blockchain transactions, filling a critical void in the way automated software systems engage with cryptocurrency infrastructure.
Based on the announcement released Monday, the standard establishes a unified approach for AI agents to interact with and utilize wallets across various tools and blockchain networks, eliminating fragmented configurations where individual systems handle their own private keys and account balances. The framework enables agents to function from a consolidated fund pool instead of managing multiple isolated accounts.
AI agents can employ standard building blocks, such as APIs, to communicate with other agents and humans, receive and send money, and access and interact with the internet

According to MoonPay, current initiatives aimed at facilitating machine-driven payment systems concentrate on transaction infrastructure but fail to resolve the challenges surrounding wallet and key management.
The newly introduced system maintains private keys within an encrypted vault stored locally and executes transaction signing through an isolated process, ensuring keys remain separate from the AI agent's operational environment. Additionally, it incorporates policy control mechanisms that enable users to establish spending thresholds and transaction restrictions prior to authorization.
The standard has been released as open source with a modular architecture, featuring components that address storage, transaction signing, policy enforcement and blockchain compatibility, and can be accessed through developer platforms including GitHub, npm and PyPI.
Established in 2019, MoonPay operates as a financial technology enterprise that delivers infrastructure enabling businesses and individual users to transfer funds between traditional fiat currencies and digital assets, providing services including on-ramps and off-ramps, cryptocurrency trading and payment solutions across international markets.
According to the company, more than a dozen organizations participated in developing the new specification, including PayPal, OKX and Circle, in addition to multiple blockchain foundations and infrastructure service providers.
Companies expand tools for AI-driven crypto transactions
Cryptocurrency enterprises are progressively developing infrastructure designed to support AI agents functioning as independent economic participants.
In another announcement released on Monday, BitGo, a provider of digital asset custody and infrastructure solutions, revealed it had introduced a Model Context Protocol (MCP) server that enables AI-powered tools to interface with its developer platform through natural language processing, allowing agents to navigate wallet capabilities, transaction processes and staking infrastructure.
This integration bridges BitGo's infrastructure with AI-native development ecosystems, permitting tools like ChatGPT and programming editors to access documentation, API specifications and product details directly within their operational workflows.
This development represents part of a wider industry effort to incorporate cryptocurrency services into AI-powered systems, as organizations explore methods for software to engage with financial infrastructure while bypassing conventional user interfaces.
Additional initiatives have concentrated on facilitating machine-driven payment systems, including Coinbase's x402 protocol, which facilitates stablecoin transfers via HTTP for APIs, applications and AI agents, alongside tools introduced last week by Visa and Stripe-backed Tempo that enable AI systems to trigger payments and perform transactions through programmatic commands.
