Sep 1, 2025September 2025 (2025-09) Monthly Summary for ava-labs/core-mobile: Key delivery highlights focused on expanding mobile capabilities, improving code quality, and enabling safer feature releases. The team balanced delivering tangible mobile user value with maintainable, scalable infrastructure enhancements. - Key features delivered: - Mobile networking capability for Blockaid/vm-module: injects httpAgent and fetch into the vm-module to enable network requests in mobile environments (commit 51f2eb9b09fcc8bbaa472ccc6a93aab6fc0cc3e8). - Codebase maintenance: Type safety improvements and dependency updates, including refactoring type imports from avalanchejs and upgrading axios/form-data; bundler moduleResolution in tsconfig and axios upgrade (commits 2151fec0c1c6cd9ee6abe9169818773de59d1240 and 07aa0dbf9a2dad1a914573d07694a55bb78ccba6). - In-app update feature for mobile: new update banner and screen to initiate updates, plus About section enhancement to copy app version to clipboard (commit d45c14e37c702ef5f1c924de250e8b396ecfdef1). - Solana launch modal feature flag: remote gate to control visibility without app release (commit 10a9d283fb4833b25a44d645bea1e37fc4d5f928). - In-app DeFi features and staking enhancements: enhanced staking flows and initial deposit experiences, refactoring related hooks/screens for yield earning (commit 402035a3ed469a31a4ac433223aa797a633fd02f). - Major bugs fixed: - Deeplink handling fixes: ensured each deeplink opens a single tab and restricted processing to HTTPS URLs (commits 13ad805fbb44b45ed61c40a0255d48b9bfdd29a5 and d3801b23a1753d1953383e59e3d45cfb9a84ab63). - Overall impact and accomplishments: - Enhanced mobile network capabilities broaden the Blockaid/vm-module use cases, improving app functionality and reliability for mobile users. - Strengthened maintainability and safety with type-safe imports and up-to-date dependencies, reducing technical debt and risk across the codebase. - Accelerated release flexibility via a remote feature flag and in-app update flow, enabling faster, safer iterations without full app redeploys. - Expanded user value through in-app DeFi features and improved staking UX, supporting higher engagement and potential yield opportunities. - Opportunity to remove legacy packages (k2-mobile) and streamline the repo, reducing maintenance surface in upcoming cycles. - Technologies/skills demonstrated: - TypeScript type-safety practices, tsconfig moduleResolution strategy, and dependency upgrades (axios 1.12.0). - React/React Native patterns, including useUiSafeMutation and useRefreshStakingBalances for robust UI interactions. - Feature flagging and remote configuration for non-disruptive release control. - Deep-link handling, URL validation, and secure HTTPS enforcement for mobile navigation flows. Business value takeaway: Accelerated mobile capabilities in Blockaid/vm-module, safer code through targeted maintenance, and a more controllable release process with feature flags and in-app updates, driving improved user experience and lower risk in production.
