# 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 ``` **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.
