Breakdown:
- TokenPairSelector: 12/12 tests passing
- useTokenPairUrl: 6/6 tests passing
- Other existing tests: 26/26 tests passing
All acceptance criteria from the issue have been met:
- User can pick base and quote assets
- Order can be flipped with one control (swap sides button)
- Search/filter by code, name, or issuer
- Handles long issuer strings gracefully (truncate + copy)
- Invalid pair state is clear with message + link to change assets
- Selection reflected in URL for refresh/back navigation
- Uses existing stack (Next.js App Router, TypeScript, shadcn/ui, Tailwind)
- Matches current design patterns
Status: YES ✅
The implementation is complete, tested, and ready for push. The only linting warnings are pre-existing in the codebase and our code follows the same patterns.
