HOLYTRANSACTION WALLET 4.2.1.1 — DESKTOP PREVIEW Platforms: Windows x64, Linux amd64, macOS arm64 (Apple Silicon). Source project: holytransaction-wallet-allplatforms. Current scope The supplied source contains a PySide6 desktop installer, branded setup stages, a worker and local installation logs. Its backend writes a temporary test file and emits demonstration progress messages. It does not install a complete wallet engine, create accounts, store keys, query supported networks or submit transactions. Distribution The three downloadable files are copied unchanged from the platform release folders. SHA256SUMS.txt records their exact hashes. A matching hash establishes file consistency, not an independent security assessment or trusted publisher identity. The project documents temporary development signing; this is not equivalent to a production trusted certificate or Apple notarization. Future platforms Mobile applications and browser extensions are perspectives only. There are no current downloads or announced release dates for those platforms in this desktop project. Documentation The original August 2026 DOCX discusses historical HolyTransaction browser/mobile products and supported networks architecture. It is research context, not a release note or implementation claim for this desktop preview.
