MoonPay Launches Open-Source Wallet Standard for AI Agents decrypt.co/362162/moonpay…

Builders, this is what you’ve been waiting for. OWS by @moonpay is now supported on @arbitrum - unlocking secure, cross-chain wallet infra for AI agents. Store keys. Manage wallets. Sign TXs. All from one single wallet. Read more here 👇🏻

XRPL is now baked into the agent economy. @moonpay just open-sourced the Open Wallet Standard (OWS) a secure, local-first vault for AI agents to store keys, manage wallets & sign txs across every major chain… including XRPL Great to see @Ripple as a founding partner. One mnemonic. One interface. Keys never leave your machine.

LATEST: ⚡ MoonPay has released an open-source wallet standard that lets AI agents hold funds and execute transactions across multiple blockchains.

👀 @Ripple is one of 20+ partners for @OpenWallet Standard on Day 1!

@moonpay Awesome! Intro to Open Wallet Standard now live as audiobook & cliff notes in Grok. Secure, local-first keys for AI agents across chains—ready to power the next wave. 🤖🔑

the true value of ai x crypto is the drive for open standards like this - implementations can still be proprietary but please adopt/form standards to make your protocols/apis to be composable!

Hats off to @nj_dawn. OWS.

agi is here humans can no longer keep up with how fast ai agents themselves are accelerating their own accelerations just yesterday ... i was baffled why there isn't any standardized way to call a common @Uniswap or @1inch swap through mcp/api from @claudeai claude code or any other typical ai agent: apparently, it's too early for real developers to run this flow due to wallet providers just publishing out their CLIs this last past week and today, @moonpay announced @openwallet ows which bridges this exact gap between ai agents that autonomously think & execute and the lack of standardized local wallet support i just deleted my 1000 word draft skill/spec of yet another fragmented local cli - and then switched to use ows directly; i don't need to review agents' proposals anymore - agi is here, and agents can source/discuss/build on their own before i can even react to the latest agentic innovations... long live human-only decisions

One of the most underrated features of OWS is how it handles agent access. When you create an API key for an agent, you attach policies to it. Policies can be declarative rules — chain allowlists, expiration times — or arbitrary executables. The executables receive the full transaction context as JSON. They evaluate to a boolean. You can write whatever logic you want — spending limits, contract allowlists, time-of-day restrictions, approval workflows. The enforcement order is what makes this work. When an agent tries to sign, OWS authenticates the token, then evaluates every attached policy. All must pass (AND semantics). Only after every policy allows does OWS decrypt the key, sign, and return the result. If any policy evaluates false, the key is never decrypted.

x402 = how agents pay OWS = how they sign Both needed. Now the stack actually composes.

Don't tempt me with a good time!

MoonPay just open-sourced OWS - a local-first protocol that gives AI agents and developer tools a single way to: - Store keys. - Manage wallets. - Sign transactions across any chain. Right now, every AI agent that wants to do anything onchain has to reinvent the wallet layer from scratch - different key storage, different signing logic, different chain support. There's no shared foundation. OWS wants to fix that. Here's what it does: - Stores private keys locally (you keep custody) - Gives agents a unified way to sign transactions across any chain - Works across 170 chains and 700+ assets (inc. $USDT, $WBTC, and $PYUSD) via LayerZero PayPal, Solana, and Ripple are all behind it. When payment rails and major L1s align on a single wallet standard, it means they want AI agents moving real money on their chains/platforms. Kinda like what HTTP did for the web. Before HTTP, the internet ran on a range of protocols with information locked in silos. After HTTP, everything connected through a universal standard. OWS is trying to be the HTTP for AI wallets. Whether that happens depends on developer adoption. Standards live and die on distribution.
