Dec 1, 2024December 2024: Delivered safety, reliability, and UX enhancements for vultisig-android that reduce user error and strengthen critical workflows. Key features include consent gating for critical actions, vault creation safeguards (mandatory backups and duplicate-name guard), and address book editing. UX and error handling were improved across the keysign flow (mixed-share errors, offline QR join, blockhash-not-found), with added EVM memo decoding for transaction context. Data reliability improvements include Solana token price fetch fixes and Bitcoin fee estimation refinements. Platform stability gains include Android SDK 35 upgrade and targeted performance optimizations. Together these efforts improve user safety, operational reliability, and cross-chain transaction context.

Nov 1, 2024November 2024 saw a set of stability, UX, and performance enhancements for vultisig/vultisig-android. Key efforts centered on hardening the sign/verification flow, refining the user interface, and expanding gas handling capabilities for token operations. Notably, we delivered a major refactor of keygen/keysign to improve maintainability, enhanced QR address display for better usability, and strengthened safety by ensuring signatures occur only when the correct vault is selected. We also expanded gas/token balance handling and added an estimated EVM gas limit fetch to improve cost visibility, and introduced proactive backup reminders to reduce data loss risk. These changes collectively improve reliability, reduce user friction, and enable faster, more secure transactions across wallets.
