MoonPay open-sources Open Wallet
MoonPay released the Open Wallet Standard to let AI agents securely hold value, sign transactions, and pay across blockchains without exposing private keys—an explicit push for "agentic" payments. The spec frames wallets as interoperable, programmable APIs with agent identity, transaction scoping, and signature abstraction built in—exactly the infra patterns backend engineers will start designing around.

MoonPay published the Open Wallet Standard on March 23, 2026; the specification is MIT‑licensed and was released to GitHub, npm, and PyPI. (prnewswire.com) The launch notes contributions from “over 15” organizations, explicitly naming PayPal, Circle, Ethereum Foundation, Solana Foundation, Polygon, Base, Arbitrum, LayerZero, Filecoin Foundation, OKX, Ripple, Tron and TON among others. (prnewswire.com) MoonPay says the standard grew directly out of MoonPay Agents, a non‑custodial agent layer the company shipped in February 2026 that included x402 compatibility and multi‑chain support. (moonpay.com) Earlier in March MoonPay integrated Ledger hardware signing into its agent stack, which the company describes as the first agent‑focused wallet to support hardware‑backed transaction approval. (prnewswire.com) The announcement frames OWS alongside emerging agent payment primitives, referencing x402 (Coinbase/Cloudflare), Google’s Agent Payments Protocol (AP2) with “over 60” partners, Stripe/Tempo’s MPP for session micropayments, and Ethereum Foundation work on ERC‑8004. (prnewswire.com) MoonPay published the spec site at openwallet.sh and has related code and demo repos under its GitHub organization, including CLI and signature tooling that the company says underpinned the standard’s reference implementations.
