MoonPay open-sourced OWS in March 2026 (PR Newswire). openwallet.sh describes it as a local-first standard: keys are encrypted with AES-256-GCM under ~/.ows, policy checks run before any key is used, and agents authenticate with scoped API tokens rather than seeing plaintext keys. It ships as @open-wallet-standard/core on npm, with PyPI and crates.io packages, and has MCP, SDK, CLI and REST interfaces. The GitHub repo is MIT, has 370 stars and was last released as v1.4.2 on 2026-06-19.
