Overview

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.

Self-reported rows are the project’s own words, dated when we recorded them — not a check. Only reproduced and reviewed rows carry a mark. None of these rows is a safety or quality rating.

This is the share of our daily checks that succeeded — not an availability guarantee. A check can fail because the host was down, because our runner timed out, or because the network in between dropped it, and only the first of those is a fact about this project. Failures are split by what we can attribute; anything we cannot attribute is counted, not hidden.

A gap is a day we have no attributable observation — never a zero. Thirty points is the whole shape the free layer carries; the daily rows behind it stay in the snapshot series.
