MoonPay open-sources a wallet standard so AI agents can actually spend money

MoonPay launched the Open Wallet Standard yesterday, an MIT-licensed open-source fMoonPay launched the Open Wallet Standard yesterday, an MIT-licensed open-source framework that gives AI agents a secure, universal way to hold funds, sign transactions, and pay for services across every major blockchain without exposing a private key.

The gap it fills: Coinbase, Google, Stripe, and the Ethereum Foundation have all shipped payment protocols for AI agents over the past year. Every single one assumes the agent already has a wallet. None of them defined where that wallet lives or how keys are stored. OWS is that missing piece.

The practical problem it solves is fragmentation. An agent running across three different tools today has funds scattered across three separate wallets that cannot see each other. OWS replaces that with one encrypted vault on the user’s machine, one interface for every chain.

Single seed, all chains: One seed phrase derives addresses across EVM, Solana, Bitcoin, Cosmos, Tron, TON, Sui, Filecoin, and XRP Ledger.
Policy engine: Spend limits, chain allowlists, and time-bound authorizations enforced before any key is touched.
Zero key exposure: Keys are decrypted only to produce a signature, held in protected memory, and wiped immediately after. The agent never sees them.
Local-first: The vault lives on the user’s machine. No cloud, no remote key management.

The coalition behind it includes PayPal, Circle, OKX, Ripple, the Ethereum Foundation, Solana Foundation, TON Foundation, Base, Polygon, Sui, Filecoin Foundation, LayerZero, and Arbitrum among others — over 15 organizations in total.

MoonPay CEO Ivan Soto-Wright put it plainly: “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.”

Available now: GitHub, npm, and PyPI. Install in one line: curl -fsSL https://openwallet.sh/install.sh | bash
The open question: Liability frameworks for autonomous agent payments don’t exist yet. When an agent sends funds somewhere it shouldn’t, nobody knows who is responsible.

The Bottom Line: The infrastructure is ready. The real question is whether you trust your agent enough to hand it your wallet.
