July 2026: Focused on reliability, correctness, and performance improvements in the Android wallet stack. Delivered lifecycle-aware swap quote polling, TON integration enhancements with on-chain settlement verification, and multiple bug fixes that improve transaction safety and balance accuracy. These changes reduce failed/undetected edge cases, minimize background load, and demonstrate strong cross-provider robustness and test coverage.

June 2026 monthly summary for the vultisig team (Android and iOS). This period delivered high-impact features, significant refactors for testability and performance, and targeted reliability fixes across core flows. The work emphasizes business value through improved user experience, faster iteration, and more robust data loading and transaction flows.

May 2026 — Consolidated stability, performance, and business-value improvements across the Android wallet. Key features delivered include Bitcoin PSBT signing for dApp co-signing (SignBitcoin) with production-ready PSBT flow and unit tests, and the Unlimited Approval warning indicator (Phase 1.6) to surface risk signals earlier in the Send flow. Expanded test coverage and code-quality efforts increased maintainability and reduced risk across releases. Major bugs fixed improved resilience in SecurityScanner (Blockaid Simulation Error crash), THORChain/MayaChain DeFi nested-scroll crashes, LazyList subcompose/Android 15-16 crashes, and content URI read failures, significantly reducing crash surfaces for end users. UX polish across DeFi screens—LP join views, token-chain badges, and memo routing—enhanced clarity and consistency with the extension. Performance improvements moved QR decoding off the main thread and optimized bitmap handling to reduce UI jank. Technologies demonstrated include Kotlin, Jetpack Compose, coroutines, Kotlin test tooling (JUnit5/Kotest), ktfmt formatting, and robust testing strategies.

April 2026 — Vultisig Android: Delivered stability hardening across core modules, UI/theming modernization, modular validation for forms, and deposit-flow refinements. Strengthened error handling in master key handling, peer discovery, swap flows, and network operations; introduced safeLaunch for network calls to prevent crashes; refactored large SendFormViewModel into focused components and extracted ChainValidationService for testable validators; centralized theming tokens and UI gradients to improve consistency and maintainability; streamlined MayaChain deposit options and performed lint/config cleanups to improve developer productivity. These changes reduce crash surface, improve reliability in network interactions, and accelerate feature delivery, driving better user experience and maintainability.

March 2026 (2026-03) — Delivered cross‑platform improvements across Android and iOS, focusing on onboarding, reliability, and code health. Highlights include: Android: agent‑ready issue templates, loadAllAssets in SelectAssetViewModel, Cardano WalletCore integration for UTXO, DeFi cache consolidation, and ktfmt formatting with UI polish; iOS: Referral flow optimization and enhanced Transaction History with clearer failure reasons. Across both platforms, improved state management (StateFlow), performance optimizations, and numerous stability fixes (crashes, network handling). These changes reduce support burden, speed up feature delivery, and strengthen platform parity.
