Recompose deprecated in 2018 (7 years ago) requiring migration to modern patterns. Account recovery feature using outdated architecture creating maintenance burden and future compatibility risks.

Modernization Solution: PR #705 completely reimplemented recovery using modern React Native architecture:

  • Replaced deprecated recompose with function components (current React standard)
  • Implemented nested navigator pattern for recovery flows (cleaner architecture)
  • Modernized component architecture throughout recovery
  • Addressed technical debt from 7-year-old patterns

Work Completed:

Technical Impact: Significant architectural improvement establishing foundation for future maintenance. Function components represent current React Native best practice. Nested navigator provides cleaner, more maintainable navigation architecture. Removes deprecated dependency eliminating future compatibility issues. Improves code clarity making recovery features easier to understand and modify.

Maintenance Philosophy: Work demonstrates commitment to maintaining code quality even in maintenance-mode applications. Rather than minimum-viable fixes, team invested in proper modernization. Prevents technical debt accumulation that would eventually make any changes prohibitively difficult. Important maintenance work preventing gradual decay into unmaintainable state.

Technical Details: Recompose was React component composition library deprecated in 2018 when Hooks introduced. Function components with Hooks represent current standard pattern. Nested navigator pattern from React Navigation provides better separation of concerns for complex multi-step flows.

Investment Significance: Substantial effort for maintenance-mode application. Demonstrates prioritization of code health and maintainability over feature velocity. Ensures application remains modifiable for future needs.

Sextant v2 Foundation

Context: New sextant-v2 repository created late June representing next-generation account creation infrastructure.

Business Context: Sextant is shared account creation platform powering Anchor, MetaMask Snap, Unicove, and Web Authenticator. Original sextant serves multiple products but represents older architecture. Web Authenticator pushing toward production deployment likely exposing scaling or architectural needs requiring sextant evolution.

Approach: Ground-up rebuild rather than incremental updates:

  • New repository (sextant-v2) instead of updating original
  • Template-based foundation using Bun for rapid development
  • Created late in month (June 25) suggesting early planning stage
  • Minimal initial content representing foundation work

Work Status: Repository created June 25 with template-based setup. README contains placeholder instructions for template customization. No significant implementation yet - represents early foundation phase.

Technical Impact: Signals major infrastructure investment in account creation platform. Clean slate approach enables modern architecture without legacy constraints. Multi-product infrastructure critical for ecosystem - improvements benefit all consuming applications. Timing aligns with Web Authenticator production push likely supporting its scaling needs.

Strategic Significance: Account creation remains critical onboarding infrastructure. Quality and reliability of account creation directly impacts user adoption across all products. Investment in v2 demonstrates commitment to robust, scalable onboarding infrastructure.

Future Implications: Major infrastructure projects typically span multiple months. Sextant v2 creation in late June suggests extended development timeline. Success critical for Web Authenticator production deployment and ongoing onboarding improvements across all products (Anchor, MetaMask Snap, Unicove).

Architecture Evolution: Modern service template with Bun runtime. Contract codegen support for blockchain integration. Likely represents evolution from original implementation addressing lessons learned from production usage.
