MoonPay is making a quiet but meaningful move into the future of crypto and AI.
The company has introduced the Open Wallet Standard (OWS), an open-source framework aimed at solving a problem that’s starting to matter more: how AI agents actually hold and use money.
The update, shared here, lays out a system where AI agents can store value, sign transactions, and make payments across different blockchains, without ever exposing private keys. It’s a small shift in design, but it changes how these systems can safely operate at scale.
A Universal Wallet Layer For AI Agents
As AI agents become more capable, one gap has been pretty obvious, they don’t have a clean, secure way to manage funds on their own. That’s what OWS is trying to fix.
Instead of giving an agent direct access to a wallet’s private key, the system separates the signing process entirely. The agent can still initiate transactions, but the sensitive part, handling the key, happens in the background, in a controlled environment.
In practice, this means an AI agent can send payments, interact with smart contracts, or move assets across chains without ever “touching” the key itself. It’s a safer setup, especially for systems that are meant to run autonomously without constant human oversight.
One thing that stands out with OWS is the level of support behind it. This isn’t just a solo effort.
More than 15 organizations contributed to the standard, including names like PayPal, OKX, Ripple, and Circle.
On the blockchain side, groups like the Solana Foundation and the Ethereum Foundation are also involved, along with networks such as Base, Polygon, Arbitrum, TON, and Sui.
That kind of collaboration usually signals something bigger than a one-off release. It suggests the industry is starting to align around shared infrastructure for AI-driven finance.
OpenWallet Protocol And The Shift Toward Local-First Design
Alongside OWS, MoonPay also open-sourced OpenWallet, which focuses on how keys are actually stored and used.
What makes it interesting is the “local-first” approach. Instead of relying on cloud services or custodial setups, everything happens on the user’s device. The wallet vault stays local, and transaction signing happens instantly without needing to ping a server.
That reduces both risk and delay. There’s no external system holding your keys, and no extra step where something could go wrong. As more developers move toward self-hosted AI agents, this kind of setup feels more practical.
How OWS Fits Into A Growing Payment Stack
OWS is just one part of a larger picture that’s slowly coming together.
Other tools are already tackling different parts of the same problem. For example, x402 has been working on token support and authentication, while MPP is exploring more flexible payment flows, including streaming payments.
What OWS does is fill in the missing layer, the wallet itself. While those systems focus on how payments move, OWS focuses on how assets are held and how transactions are approved.
Put together, it starts to look like a full stack for AI-powered payments, where each piece handles a specific role.
Security Model Designed For Autonomous Systems
Security is where most of the thought has clearly gone.
Instead of leaving keys exposed, the system only decrypts them when needed, inside a separate process. They’re held briefly in protected memory, used to sign a transaction, and then wiped immediately.
Even the AI agent running the transaction doesn’t get direct access to the key. That separation is important. If something goes wrong on the agent side, the keys are still protected.
For systems that are meant to operate independently, this kind of design isn’t just helpful, it’s necessary.
Building Toward An Autonomous Financial Future
By open-sourcing OWS under an MIT license, MoonPay is also making it easier for others to build on top of it. Anyone can use it, modify it, or integrate it into their own projects.
That openness could speed things up across the space. As more teams experiment with AI agents that can transact on their own, having a shared standard like this removes a lot of friction.
The bigger shift here is subtle but important. AI agents are starting to move from being tools to becoming participants in the economy. And if they’re going to operate at that level, they need infrastructure that actually supports it.
OWS is one step in that direction. Whether it becomes widely adopted is still an open question, but it’s clear the groundwork is being laid.
