MoonPay open wallet standard
MoonPay published an Open Wallet Standard — an open-source wallet framework that lets AI agents securely hold and spend crypto across chains without exposing private keys. That creates a primitives layer for agentic commerce and programmable payments, which could matter for SaaS or CPG pilots experimenting with tokenized loyalty or automated agent workflows.

MoonPay published the Open Wallet Standard on March 23, 2026 and framed it as the open-source successor to internal tools MoonPay developed this year. (moonpay.com) The launch package lists contributions from “over 15” organizations, explicitly naming PayPal, the Ethereum Foundation, the Solana Foundation, Ripple, OKX, Tron, the TON Foundation, Base, Polygon, Sui, the Filecoin Foundation, LayerZero, Circle and others. (moonpay.com) The core repo documents a pre-signing policy engine that enforces chain allowlists, expiries and custom executables before key decryption, and it advertises local, policy-gated signing to keep key material encrypted at rest. (github.com) OWS exposes SDKs and a CLI with Node and Python bindings plus a Rust core, and the project is published on GitHub, npm and PyPI to enable cross-tool wallet portability. (github.com) MoonPay and coverage note native support for external payment rails and standards at launch, including Coinbase’s x402 and Tempo/Stripe’s Machine Payments Protocol, and the project builds on MoonPay’s Ledger hardware-signing work. (decrypt.co) The GitHub repository shows active development metrics — several hundred commits at launch and visible community signals such as stars and forks — indicating the codebase is already receiving public contributions. (github.com) MoonPay released the standard under an MIT open-source license and explicitly positions OWS as a shared, chain-agnostic wallet layer intended to make wallets created by one tool usable by others.
