# All Issues and Errors Fixed ✅

## Summary
All issues and errors in the bridge dApp have been identified and resolved.

## Issues Fixed

### 1. React Router Future Flag Warnings ✅
**Issue**: React Router v6 warnings about future flags for v7 compatibility
**Fix**: Added future flags to `BrowserRouter` in `App.tsx`:
```typescript
<BrowserRouter
  future={{
    v7_startTransition: true,
    v7_relativeSplatPath: true,
  }}
>
```
**Status**: ✅ Fixed - Warnings eliminated

### 2. useContractRead "requires X arguments" Errors ✅
**Issue**: Thirdweb's `useContractRead` was trying to execute with `undefined` or `null` arguments, causing "Function requires X arguments, but 0 were provided" errors
**Fix**: 
- Use zero address (`0x0000000000000000000000000000000000000000`) as placeholder when `address` is not available
- Use zero amount for fee calculation when amount is invalid
- Always pass valid argument arrays instead of `undefined` or `null`
**Files Modified**:
- `src/components/bridge/BridgeButtons.tsx`
**Status**: ✅ Fixed - No more argument errors

### 3. TypeScript Unused Variable Warnings ✅
**Issue**: TypeScript compilation warnings for unused variables
**Fixes**:
- Removed unused `refreshKey` state variable from `BridgeButtons.tsx`
- Removed unused `LoadingSkeleton` import from `XRPLBridgeForm.tsx`
- Removed unused `useEffect` import from `Tooltip.tsx`
**Status**: ✅ Fixed - TypeScript compilation passes with no errors

### 4. Balance Display Logic ✅
**Issue**: Balances might show incorrect values when wallet is not connected
**Fix**: Updated balance display to only show actual balances when wallet is connected, showing "0" or loading skeleton otherwise
**Status**: ✅ Fixed - Correct balance display

### 5. Refetch Error Handling ✅
**Issue**: Refetch functions might throw errors when contracts aren't ready
**Fix**: Added error handling with `.catch()` to gracefully handle refetch failures
**Status**: ✅ Fixed - Robust error handling

**Warning**: `Lit is in dev mode. Not recommended for production!`
**Status**: ⚠️ Informational only - This is expected in development mode and doesn't affect functionality. Will be resolved in production builds.
