MoonPay launches open-source wallet standard to help AI agents manage funds across blockchains

MoonPay Launches Open-Source Wallet Standard for AI Agents - Decrypt

The standard addresses wallet and key management fragmentation challenges while enhancing security for AI developers. Crypto payments infrastructure company MoonPay has launched an open-source wallet standard designed for AI agents to manage funds and execute transactions across multiple blockchains, addressing key infrastructure challenges that have limited AI-crypto integration. The Open Wallet Standard (OWS), announced Monday, was developed with contributions from PayPal, the Ethereum Foundation, the Solana Foundation, Ripple, OKX, Tron, TON Foundation, and Base, among other companies. "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," said MoonPay co-founder and CEO Ivan Soto-Wright in a statement. The framework aims to solve fragmentation issues in wallet and key management that have complicated financial operations for autonomous AI systems, according to MoonPay, which is an investor in Decrypt's sister company Myriad. OWS supports the x402 open payment protocol developed by Coinbase, along with Stripe and Tempo's Machine Payments Protocol (MPP) for session-based micropayments. It also builds on MoonPay's earlier collaboration with Ledger that enables hardware wallet signing for MoonPay Agents transactions. "On-chain payments originate from wallet addresses, and every chain represents them a bit differently," said Mysten Labs co-founder and CTO Sam Blackshear in a statement, explaining that a "unified representation" streamlines processes and enables agents to focus on high-level tasks instead of details. According to MoonPay, OWS is designed in such a way that a wallet's private key is never exposed to agents, the LLM context or parent applications when transacting. The launch comes as AI agents increasingly require sophisticated financial capabilities to operate autonomously, and forms part of a "deliberate shift" at MoonPay towards AI-native infrastructure. Agentic payments are a growing concern for crypto infrastructure developers, with Coinbase launching a wallet specifically for AI agents with built-in guardrails, Stripe-backed Tempo Network focusing on enabling AI agent payment capabilities, and Sam Altman's World tapping Coinbase's protocol to verify humans behind AI agents.

MoonPay Unveils Open-source Wallet Framework for AI Agents

The framework aims to let AI agents hold funds and execute transactions across blockchains, addressing fragmented wallets and key management. MoonPay has released an open-source wallet standard designed to let AI agents hold funds and execute transactions across blockchains, addressing a key gap in how autonomous software interacts with crypto systems. According to Monday's announcement, the standard introduces a shared way for AI agents to access and use wallets across tools and blockchains, replacing fragmented setups where each system manages its own keys and balances. It allows agents to operate from a single pool of funds rather than across multiple disconnected 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 researchers at MIT Sloan. MoonPay said recent efforts to enable machine-driven payments focus on transaction rails but do not address how wallets and keys are managed. The new system stores private keys in an encrypted local vault and signs transactions in an isolated process, keeping keys out of the AI agent's runtime. It also includes policy controls that let users set spending limits and restrictions before transactions are approved. The standard is open source and modular, with components covering storage, signing, policy controls and chain support, and is available through developer platforms including GitHub, npm and PyPI. Founded in 2019, MoonPay is a financial technology company that provides infrastructure for businesses and consumers to move funds between fiat and digital assets, offering services such as on- and off-ramps, trading and crypto payments across global markets. The company said more than a dozen companies contributed to the new specification, including PayPal, OKX and Circle, alongside several blockchain foundations and infrastructure providers.

In a separate announcement on Monday, BitGo, a digital asset custody and infrastructure company, said it had launched a Model Context Protocol (MCP) server that allows AI-driven tools to access its developer platform using natural language, enabling agents to navigate wallet functions, transaction flows and staking systems. The integration connects BitGo's infrastructure to AI-native development environments, allowing tools such as ChatGPT and code editors to retrieve documentation, API references and product information directly within workflows. The move reflects a broader push to integrate crypto services into AI systems, as companies experiment with ways for software to interact with financial infrastructure without relying on traditional user interfaces. Other efforts have focused on enabling machine-driven payments, including Coinbase's x402 protocol, which enables stablecoin transfers over HTTP for APIs, apps and AI agents, as well as tools launched last week by Visa and Stripe-backed Tempo that allow AI systems to initiate payments and execute transactions programmatically.
