Jul 1, 2025

July 2025 highlights for shanimal08/universe: four core feature areas were delivered — Security & PIN Management UX, Wallet Connectivity and Identification, Offline Signing with cost reductions, and Settings/UI/Setup refinements. The work includes focused commits to strengthen security prompts, refine PIN flows (including masking and autofocus), and unify keyring handling; standardize wallet identification and robust HTTP-based wallet connectivity; introduce offline signing via SpendWallet with lower fees for one-sided transactions; and streamline setup and telemetry with remote-node improvements and enhanced node status visibility. Several bug fixes addressed security dialog texts, PIN-related issues, denial handling in keyring flows, seed backup checks, and edge cases like external Monero addresses during PIN creation. The overall result is improved security, reliability, cost efficiency, and user experience, with stronger developer velocity and maintainability.

Jun 1, 2025

June 2025 — Delivered a reliable wallet experience and stabilized core transaction flows in shanimal08/universe. Key features include Wallet Transaction Flow and History Enhancements with UI sending flow, enhanced history, export/import, zero-amount validation, and payment references after 5 confirmations. Implemented Tor Linux libevent handling to robustly start Tor when libevent is absent. Ensured immediate block height updates on mine to improve fund visibility. Tuned payref processing timeouts during node setup to boost reliability for version 1.2.9. Business impact: clearer user history, faster settlement visibility, and higher reliability with fewer support issues. Technologies: UI/UX flows, libevent loading via LD_PRELOAD, block height logic, and process timeouts.
