Note

Displays sync progress with 5-decimal precision for Piratechain wallets, gated by a new SpecialCurrencyInfo flag, plus minor typing tweaks.

• UI:
  • src/components/themed/BuyCrypto.tsx: Shows sync progress using toPercentString(syncRatio, { minPrecision: 5, maxPrecision: 5 }) when SPECIAL_CURRENCY_INFO[pluginId].highPrecisionSyncRatioDisplay is true.
• Constants:
  • src/constants/WalletAndCurrencyConstants.ts:
    • Add highPrecisionSyncRatioDisplay to SpecialCurrencyInfo and enable it for piratechain.
    • Use strict undefined check in getSpecialCurrencyInfo.
    • Add explicit return type to getFiatSymbol.

Bug: Robust Destructuring for Optional Data

Destructuring SPECIAL_CURRENCY_INFO[pluginId] directly will throw a runtime error if the pluginId doesn't exist in the record. The code should use getSpecialCurrencyInfo(pluginId) or add a nullish coalescing operator (?? {}) to safely handle missing entries, similar to how other parts of the codebase handle this case.
