Jaime Toca Muñoz contributed to vultisig/vultisig-android by engineering cross-chain wallet features, swap enhancements, and robust transaction workflows over six months. He unified fee estimation logic for EVM and Mantle chains, expanded TRON and Solana integrations, and improved swap reliability by converting token fees to native currency. Jaime enhanced the referral and onboarding flows, implemented security scanning with Blockaid, and refined UI/UX with Jetpack Compose and MVVM architecture. His work in Kotlin and Android focused on maintainable state management, error handling, and CI-driven testing, resulting in a more stable, user-friendly wallet that supports diverse blockchain assets and secure transactions.

Month: 2025-11 — Key delivery across vultisig/vultisig-android focused on UX improvement for Discount Tiers. Implemented single-expand behavior by updating DiscountTiersViewModel to collapse all other tiers when a new one is selected, ensuring only one tier is expanded at a time. This reduces confusion, improves usability, and aligns with product goals. Work is tracked with commit df4d2e10d31d20f53d920d7c1ee22ee26ba2a274 ('close other tiers (#2749)'). No major bugs fixed this month in this repository. Overall impact includes improved user experience, maintainability, and state predictability. Technologies demonstrated include Android, Kotlin, MVVM architecture, and UI/UX optimization.
