Currency resolution and formatting invofi/apps/frontend/src/lib/formatters.ts, invofi/apps/frontend/src/lib/formatters.test.ts |
The formatter validates the stored currency, falls back to XLM, and uses the stored value when no explicit currency is provided. Tests cover persistence and explicit overrides. |
Settings currency control invofi/apps/frontend/src/app/settings/page.tsx |
The settings page adds persisted XLM and USDC radio buttons for the default display currency. |
Estimated code review effort: 3 (Moderate) | ~20 minutes
Merge Risk: 🔵 Low · up to 261a8
The settings page can briefly render inconsistently after loading a saved currency, and invalid stored values may leave no currency selected even though amounts fall back to XLM. This is a localized, mergeable risk with explicit owner follow-up.

Normalize the stored currency before rendering the radio controls.
useLocalStorage reads localStorage during initialization, so persisted USDC produces different server and browser values during hydration. Any persisted value other than XLM or USDC leaves both radios unchecked, while getDefaultCurrency() falls back to XLM. Use a hydration gate and derive the rendered value from the XLM/USDC allowlist.

useLocalStorage. The sharedformatAmountformatter falls back to this preference when no explicit currency is given.Changes
